April 10th: Lluc to Sa Calobra via Bike Shuttle


We ate breakfast early and started riding towards the pickup location at around 7:30, with pick up time at 7:45. We rolled into Port Blue exactly as the shuttle bus was rolling in. Stephan and Otto were getting into their “private shuttle” as we rolled out of Club Del Sol. He would later tell us that the “private shuttle” was actually a rescue van that was delivering repaired bikes all over the island. Nobody had told the driver that he was to carry a tandem, and the driver had to do some work to fit that long bike into the trailer.


Unlike the Andratx transfer where Port Blue was the last stop, Port Blue was actually the first stop and the shuttle pulled into Port Pollenca where there were more bikes waiting for pickup. I used the rest room and got a nice picture of the shuttle.


The shuttle ride was relatively short—it being early there wasn’t a lot of traffic to slow down the van with its trailer. We were dropped off at the Respol gas station where Otto and Stephan were already cooling their heels (they’d grabbed some food and popped back into the shuttle) waiting for us.


With that, we started riding towards Sa Calobra. Arturo would later explain to us that the name meant “The Snake” in Spanish, an apt metaphor for the twisty curves the road would take all the way down to the Mediterranean from 2400’ up.  The approach was not flat, but a series of easy rollers along baby-bottom smooth roads that characterize that part of the island.


At the high point, I kept going, only to receive a text message from Xiaoqin later saying that the kids had reached the high point and refused to keep going. Arturo said later, “It was clearly pre-planned. Boen even looked a bit disappointed.” I assumed the kids would ride home from there, since they knew the route, but they had misunderstood and would wait there the entire time. I was willing to let them do this—one of the reasons Boen brought the single was so that he had a modicum of independence, and if you don’t give your kids any rewards for independence then they would just learn to dependent the whole time.


We made it to the Sa Calobra intersection, waited for everyone to gather, and then I gave instructions: if you’re going to take pictures do it on the way down, because on the way up you might not feel like doing so. There’s a climb to the saddle, and there’s a café at the bottom so we’ll regroup there so those who want to ride the entire descent in a flow state won’t feel obliged to stop for regroups. Watch out for traffic because there are places where the road turns into a one lane road and the cars will go in both directions.


We then started the 200m climb to the summit. Once at the top, it was so warm that I decided to just start riding down without waiting for the others. I might have stopped a few times to take pictures, but by and large I just took advantage of the relative quiet to enjoy the flowy descent. At 7%, it was just gentle enough to enjoy the views while still gathering serious speed between corners.


At the bottom, I parked my bike unlocked, walked into the self-service café, bought a cup of coffee and some cake, and waited for the others. They arrived just as I’d taken the first sip. I waved the folks over and we all had a snack at the coffee shop to fuel up for the climb.


Before starting the climb, I mentioned the beach to the group, so we made the customary journey to the tunnel, passed through both tunnels, and reached the beach. It was already bustling with sunbathers, swimmers—most wearing wetsuits—and tourists.


We took photos and walked back, except for Joe, who’d realized that with his speedplays he was better off riding to the tunnel. Once we were back, I told everyone to do the climb at their individual pace, and that the regroup was at the intersection where there was a café. However, if you got there early and got bored, you could turn right onto the main road and ride 200’ up to the tunnel. Past the tunnel, you’d get a nice view of the lake/reservoir.


With that, we were off. Today was the day my training program called for a high intensity of effort, going for 180+ watts for the climb. This proved to be challenging—while 180W seems easy at the beginning, after a few minutes my heart rate started to rise, and it would keep going until it hit pretty high intensity. I tried sustaining this, but after 20 minutes I fatigued and had to back off a bit before resume that intensity. It turns out that learning to hold this power for longer is one of the differences between a structured training program and “riding any old how” the way I’d always done.


At the top, I paused and sat down for a bit. Mark caught up and we rode together to the tunnel and visited the lake. Mark was feeling frisky and rode all the way to the end of the lake and back while I turned around and went back down, parked my bike. Arturo and Joe showed up, as did Mark, and we grabbed a table in the shade. Joe was in a hurry to get back to the hotel, so he left pretty quick, but I bought a couple of cans of coke for Arturo and Mike and a glass of fresh squeeze orange juice for Xiaoqin.


When Xiaoqin came back we started riding back, because Joe texted us that our kids had been waiting for us the entire time and were hungry. Unfortunately, I’d bonked and wasn’t making good speed, though by the time I got to the kids they were already reassured by Joe that I was coming, so they weren’t antsy, though complained a bit about how long we took. “I thought you were going to go straight back to the hotel!” “Mom told us to wait!” “Really?” “Um.. maybe…”


I rode the kids to the Respol garage, where we parked our bikes, and bought a bunch of food to eat. I immediately started feeling better, and by the time Xiaoqin showed up and ate her fill we were raring to go again. The ride back down Col de Feminia was easy, despite the headwind, and when we got to Pollenca I turned on the GPS and routed ourselves back to the hotel along another of Mallorca’s narrow, beautiful backroads, dumping us within a block of the hotel at the main road.


Over dinner, we debated what to do. Everyone was so tired that Puig Major was out of the question. Mark had a proposal, which was to do parts of the roads he’d missed on the first day of riding. That didn’t appeal to me, so I decided that we would do Cap Formentor again, but early in the morning so we wouldn’t get any traffic. The kids didn’t want to ride at all, so we’d get back, eat breakfast, and then take them for a hike.


The others debated options back and forth. Stephan wanted to take both kids on the tandem (Benjamin would fit on a WeeRide, but the constraint then became to get him back to the hotel before he fell asleep). The rest eventually decided on doing the reverse of the short loop we had done 2 days before.

April 9th: Col Feminia


My jet lag was almost completely over, getting up at a normal time and eating breakfast. We hit a snag—Boen had lost the key to his bike at the bike shop! It was a 5 Euro penalty for the bike shop to break the lock, but they were pretty forgiving about it. (I”d tried to pick the lock with various tools, but the lock was clearly of better quality than the locks I had picked on Montebello road 30 years ago)


Leaving the hotel at 9:00am, we rode towards Pollenca and then headed on the gentle climb after drafting a couple of cyclists. Boen was flexing his muscles again, riding hard up the hill drawing thumbs up from the many cyclists who passed him and yet were impressed by a 10 year old riding these big mountains on his own single bike. Whatever else you can say about Mallorca, the feedback from other cyclists were making Boen quite enthusiastic. Boen finally mastered drinking from the water bottle while riding, and then placing the water bottle back onto the bottle cage.


At the top of Col Feminia, I doubled back down to pick up Bowen, who wasn’t actually very far back. From there, it was a couple of climbs before we saw the Respol gas station, which had more cyclists than a typical century lunch stop in the US. The place probably made far more money selling food to hungry cyclists than it made from selling gas!


After that, we descended down to Lluc and followed the limestone cliffs. The road here made Serpentine switchbacks along the cliffs. I had to keep reminding myself to slow down so as not to goad Boen into exceeding a safe speed, but Boen crowed with joy when he caught up t the tandem by finally shifting into his big chainring and pedaling hard.


We rode down to the valley and then back again via the bike route we were now all too familiar with. We dropped the kids off at the hotel but made sure that they didn’t keep their bike at the bike shop, but rather in the balcony of our apartment unit, since we had an early ride the next morning.


Xiaoqin had decided that her shorts were too small, and Mark was also interested in visiting the Assos Outlet so rather than just stop riding I picked up a backpack, stuck Xiaoqin’s shorts and receipts in there, and we rode to the Assos Outlet, only a half hour by bike rather than a 40 minute bus trip wich interminable waiting times at bus stop. Arturo took a look at the prices on Assos’s website and complained that a full kit from them cost more than his bike (which was an exaggeration). I was too tired to explain that only the shorts are worth it for me (though Xiaoqin loves their jerseys)  and they were 40% off at the Outlet rather than paying inflated US prices.


I’d been dreading riding the Playa du Mura strip, but to my delight our Garmins routed us onto beautiful backroads, including a gravel bypass which was a delight. Even the short section on the strip wasn’t oo bad as trains of cyclists dominating the road chased away annoying cars!


I was so impressed by the Assos half-shorts that I was determined to buy a second pair for touring use this summer. Xiaoqin exchanged her shorts for one sized bigger (despite the staff continually telling her that she really was in the right size), and found a nice pair of sunglasses as well as another item at a great price. We made it back to the hotel in time for dinner (and for Arturo to say that he would have come with us if we’d told him we were riding there instead of taking the bus) Mark didn’t find any tops his size but did buy shorts as well as the deals were really too good to pass up. We also bought cereal and lactose free milk for breakfast the next morning, as well as instant noodles and mortadella.


At dinner, we ate well. Stephan had managed to arrange for a private shuttle to take him to the Respol gas station the next day, since his tandem wouldn’t have fit in the regular shuttle and the regular shuttle was sold out anyway. He would report later that the “private shuttle” (which was not at a big premium to the regular shuttle) turned out to be a driver who was delivering repaired bikes all over the island.


The kids complained about riding the next day. I pointed out that the bike shuttle was basically giving us a free 1700’ of climbing!

That evening, Mark did extra homework and gave us a new route that started from the Respol gas station instead of Lluc proper. In addition, he noticed that there was the possibilities of using the backroads through Pollenca instead of the main road we had ridden the day before.

Review: The Beauty of Falling

 The Beauty of Falling is a memoir/teaser for Claudia de Rham’s theory about heavy gravitons I claim it’s a teaser since it doesn’t actually cover any of the math involved in her theory. In fact, I was nonplused by her statement that with a high mass graviton could exist, since my understanding was that gravity waves travelled at the speed of light and anything that had to travel at the speed of light had to be massless.

(A book I later read talked about how photons can have gravitational effect, since spacetime isn’t warped just by mass, but also by energy due to the mass-energy equivalence)

The memoir part of the story is pretty amazing—born in Lausanne and then having an international lifestyle, she spoke multiple languages with an accent, which apparently can be annoying as everyone you meet tells you it’s amazing how quickly you learned their language, not knowing that she was a native speaker.

A large part of the book covers her attempts to become an astronaut and making it deep into the selection process until she was disqualified for having a latent TB infection acquired during her time in Madagascar.

I happen to know professional physicists and I can attest to their extreme travel lifestyle. It’s definitely not an easy lifestyle that’s conducive to raising kids and I can only imagine doing so while attempting to qualify for the European astronautics program makes it even more challenging—she describes taking flying lessons as soon as she could afford them as part of her plan.

I enjoyed the book, but I’m afraid I didn’t come away with any more understanding of how heavy gravitons change how we view gravity than before reading the book.

April 8th: Emita de la Victoria

We all woke up late and had a leisurely breakfast. Before getting organized for the hike, I replaced Bowen’s front tire. I also took the time to rewax my chain and Xiaoqin’s chain rather than replace the chains with freshly waxed chains we’d brought with us. For the hike, Arturo was so impressed by Emita de la Victoria that we booked 2 taxis to do the hike. This was an out and back hike to the summit of the peninsula, which granted us a nice view of the area. Unfrotunately, Benjamin’s stroller couldn’t get up the super step stuff, so when we had all regrouped we elected to walk back to the bus stop at Bonaire.


The bus stop at Bonaire, however, turned out to be decommissioned, so we had to order taxis anyway though the taxi was cheaper this time since w’d walked a couple of klometers off the fare! Back at the Club Del Sol, Mark suggested going sailing on the Hobecat rental he’d seen in Pollenca. Boen was at first excited but as soon as they mentioned they were going to ride there Otto mysteriously got a headache and Boen decided not to bother. The kids definitely took the “rest” part of the rest day seriously.


Xiaoqin and I had spotted that there was an Assos Outlet and I determined that we could visit the Outlet by bus. It was a 40 minute journey, but once there I found what I had never found before in the US, which is size medium Assos men’s half-shorts (no-bibs) at 75 Euros. I actually test wore both the medium and the large and they both seemed to fit fine, but the staff there looked at me and said, “You’re a medium. Large is too large.” Xiaoqin had found some shorts, a nice jersey and a jacket as well. We spent our money and made it back to dinner.


At dinner, we discussed the next day’s route. I walked through all the options, including Ruda Cuda, which was an 82 mile ride. With fresh memories of the 83 miles the day before in mind, nobody was excited about that. I’d also suggested doing Cap Formentor again—in fact, everyone agreed that Joe who hadn’t done the lighthouse ride chose the next day to do so, and to do it early. With an e-bike, he could leave at 7:00am, bike to the top of the lighthouse, and get back to the hotel before the breakfast room was closed and avoid all the traffic we had seen on Monday!


We eventually decided on a short loop I’d designed to climb Col Feminia, and then descend to Lluc. I’d laid it out so that folks would have a chance to ride up Col Feminia which was the designated descent for Friday’s ride, where Sa Calobra would eliminate any desire to take the harder route back to the hotel if ridden at maximum intensity.

Review: Empire of AI

 Empire of AI is about OpenAI, with the inside story about how a couple of years ago over a weekend, Sam Altman got fired by the non-profit board and then got himself brought back. It's got all the juicy details behind that backstory, and describes a high level of corporate politics that I'm glad I've never had to witness first hand, despite having various toxic managers in the course of my long career in Silicon Valley.

The book is also about a lot more, such as the environmental and social costs of the scaling up of modern LLMs. The problem with the author's approach, however, is that she appears to be writing for a non-technical audience, giving you abstract ideas of the environmental costs of serving a gemini query vs a regular google search. I would have rather gotten absolute numbers. There's an entire section on how the human reinforcement folks in 3rd world countries working for scale.ai or one of those analogues suffered from mental health problems. But any skeptical reader would see that the fact that those workers continued working indicated that they didn't actually have any better jobs available, and that the AI sweatshops were actually the best jobs they could find!

Ultimately, I came away with an understanding of how Sam Altman could get so much resources to build massive data centers and consumer 40% of the world's RAM production. But if you had a computer scientist's mind, you'd also realize that the current LLM approach is already hitting their limits --- when you've already added all of reddit and 4chan into your training corpus and is already using video to speech to create more text for your LLM to train on, where's the next order of magnitude of scaling up going to come from? Sooner or later you're going to hit diminishing returns (assuming you haven't already), and I'm guessing that eventually the lawsuits about OpenAI and other companies illegally scraping content they didn't have permission to use will get to the point where those creators would have to be compensated.

Anyway, the book is good reading (but you need to read it with skepticism), and I'm guessing the OpenAI employees are getting paid so much so they will happily put up with a level of toxic politics that I've never encountered.

April 7th: Andratx to Club Del Sol

Waking up early, we ate breakfast in our room, which had a kitchenette so we could make instant noodles and a couple of coffee pods. Mallorca is on the far end of the central European time zone, which meant it would be dark fairly early in the morning, but in exchange it stayed light enough for cycling until 8:00pm.


The bus ride was  uneventful. I’d always assumed that people taking the bus were all going to do the gorgeous coast route, but in fact, the English cyclists who shared the bus with us were planning to use the easier inland route. They were very impressed when they heard that Stephan and Otto were also going to do the coast route.


The coast route to Estellences starts with a 1000’ 5% grade. Joe was worried about his battery lasting the entire day, so he chose to do the first couple of climbs without battery assist. Once past the first climb, the ride develops an undulating character, swooping up and down the contours of the terrain, granting beautiful views of the mediterranean that rival California’s highway 1. What made it better, of course, was that first, the road was in exceedingly good condition, amost perfectly smooth, as though repaved only in the past year or so. Mallorcan drivers are also far more polite than their California counterparts.


We stopped for coffee early on, and ate Empanadas and had coffee to fight jet-lag. After that we rode to Esporles and then towards Deia, where a supermarket lunch was the order of the day. At this point, the group was broken up—Xiaoqin, Joe, myself, and Mark Brody in the forward group, with Arturo providing support for Stephan and Otto on the backend.


Past Deia, the road does one final climb before descending to Soller where rather than ride Puig Major we would ride Col Soller, itself a 1600’ climb from almost sea level. What sucks about Soller is that the road pavement is terrible, and up until the auto-only tunnel, cars and bicycles share the same road. At the tunnel entrance, however, bicycles get to ride the old road rather than the tunnel. While this adds 1000’ of climbing, in the mid afternoon the shadows were long enough to provide ample shade, and there’s a café at the top that wasn’t there the last time I rode by 7 years ago.


I was feeling bloated and mildly nauseated from having eaten so much over the day, so all I did was order a lemonade to share with Xiaoqin. Mark came by, and then we all elected to ride together the rest of the way. Mark had routed us through Bunyola, where we did decide to give the Orient valley a pass for lack of time. From there, it was not 10 miles of riding before we hit the bike path we saw 2 days ago. Since I now knew all the short cuts I took over navigation duties. I even had enough energy for a finishing spring kick.


We made it back to Club del Sol just in time to take a shower before dinner with the kids., who had gone for a ride with Adria Bauza, a guide highly recommended by Brad Silverberg. Ironically, the kids had ridden the Orient Valley via ar shuttle (which had newly paved roads) , and they would be the only ones to ride the Orient valley on the trip. Bowen even had a flat which highlighted that his front tire had worn out. Good thing we had a spare tire with us!


Arturo, Stephan and Otto would make it right after dark, giving themselves 15 minutes to load up their plates for dinner. That night, Arturo's call for an after dinner walk got no takers.

The kids had had a great time with Adria, and they considered the ride with him one of the two best rides on the trip.

April 6th: Cap Formentor


The last time I’d gotten to Mallorca, I’d ridden every road I could, but at the last minute Linus Gerdemann had informed me that I had neglected to include Cap Formentor. This time, I was determined to rectify that oversight. Rosie would join us today so Stephan and Otto had a chance to rest up in preparation for Tuesday’s cross island tour.


We rode North from the hotel, through the beach area of Port Pollenca before finding the main road to the Formentor lighthouse. Stephan had ridden this route earlier, and said that he’d never seen so many road cyclists on one road. Indeed, even though the hour wasn’t late there were cyclists in both directions (the route was an out and back).


After the first climb, the road descends almost all the way down to sea level before winding away around the Peninsula. As we started the second climb, Bowen rode up and said, “My shifter doesn’t work.” One look and it was obvious that his shift cable was a goner, along with the barrel adjuster on his downtube. Arturo happened along, which was fortunate. He ripped the cable away from the stop and make-shifted a knot. The chain settled onto 4th gear, which would let Bowen finish the ride albeit without the ability to shift.


To Bowen’s credit, he refused to let this obstacle stop him. He kept going on a single speed, demonstrating that even if he kept professing that he didn’t like riding, once he got started he had the will to finish. The ride passed through a tunnel, and then a final descent before a short climb to the lighthouse itself. The final approach had turned into a parking lot—there’s no metering for parking at the lighthouse, and despite it being a Monday the parking lot was already full and cars were now jammed up along the road, with many drivers making the ill advised decision to do a 3 point turn on a single road adding chaos to the clutter. While everyone agreed that the ride was gorgeous, we all agreed that the traffic was the least favorite thing about the ride.


I started descending from the lighthouse but then I heard Mark shout “Piaw, wait up!” A cyclist caught up to me and asked me if I had an 11s quick link. Normally I would have an extra quick link, but because Formentor was so short, I had swapped out my normal saddlebag for my extra small saddlebag which did not have any spare quick links! I was flattered that everyone thought that I was the kind of person who would have such spares and normally I did, but not today! I would remember much later that I actually did have a spare quick link in Xiaoqin’s saddlebag but she’d already gone on ahead!


The return felt far easier than the outbound leg of the journey. Part of it was that Xiaoqin was going to pace Bowen while I paced Boen. Boen had elected to bring his single bike on this trip and he was making the most of it, attacking each climb with vim and working for all he was worth, able to stay in any draft on the flat.


At the top, we waited for Bowen before doing the hike and then doing the descent to Pollenca, where we went to find a bike shop that could replace his derailleur cable. It took 2 tries since the first one we tried was about to close for lunch. I had also assembled the crank wrong, leaving too much space on the left crank, and I tried to borrow a Shimano tool to fix it, but the shop mechanic said he’d just fix that as well.


Boen wanted to head back to the hotel to play with Otto, so he rode off with Arturo while Xiaoqin, Bowen and I had lunch while waiting for the bikes to get fixed. Just as we had finished eating, the bikes were done. The charge—15 Euros including the replacement cable.


We rode back with no incident. To my delight, the buffet dinner was different every night and would remain so every day of the trip. Joe had arrived and picked up his rental bike. We had to get up and leave at 7:00am the next day for the shuttle to Andratx for the ride across the island. We discussed various options. Mark suggested that we leave out the Orient valley to save about 1000’ of climbing, and that appealed to most people.

Review: Exit Interview

 Exit Interview is Kristi Coulter's memoir of her 10 years at Amazon. The title of the Chinese translation of this book translates back into English as "I spent 10 years at Amazon and needed alcohol and a psycho-therapist." Clearly, the Chinese translation could save you a ton of time reading!

In all seriousness, the book traces her abandonment of a quiet Michigan career in a company where not much was happening, through her interview loop at Amazon, which led to her being the senior manager of the merchandising team. In 10 years, she'd managed to go from that to managing the Amazon Crossings (translation) imprint, to being part of the management training program to running the ill-fated Amazon Go's writing team.

The book has several themes, one is that the internal corporate culture of Amazon is just as dysfunctional (or functional) as any other tech corporation on the planet, but if you're coming from outside tech it feels like an alien culture, especially to someone who basically went to school in the humanities. The second, of course, is being a woman at Amazon is difficult. How difficult compared to other tech companies? You couldn't tell, because Amazon was the only tech company she ever worked for so she had no frame of reference. For instance, at one point she talked to her manager about getting a promotion to Director. His response, "When you change the world, you'll get a promotion." She took it as a denial or lack of support. In the unlikely event that a man would come to me for advice, I'd tell him to switch jobs. But of course, a job switch at that point would have cost her multiple millions in valuable stock, so she stuck around. That's the kind of career trade-off anyone at FANG has to do continuously, so it came off as unsurprising.

There's also a sense of total hostility towards Amazon whenever she has to meet or talk to people outside Amazon. For instance, in the publishing industry, Amazon is treated as the outsider who wants to eat everyone else's lunch. Her internal dialogue is, "We're just this tiny experimental outfit inside Amazon that can get shut down any time now, why are you treating us as a behemoth?" This strikes me as a little disingenuous, since Amazon clearly had a larger market cap than any single publisher and also owns the biggest bookstore on the planet:

Amazon Crossing recently became the world’s largest publisher of literature in translation. If you think that must mean we published hundreds of translated books, ha-ha, no. Fewer than 3 percent of books in English are translations from other languages, so we became the industry leader with a list of just twenty-nine. Naturally, people are mad about it. (page 208)

When I talk to tech people they always "forget to count that low." Many are always surprised that all it takes is to sell 10,000 copies of a book in a month to show up on the New York Times best seller list. 

Finally, the narrative has lots of gaps. There's no description of any single event that drove her to alcoholism. That's probably because she's beholden to an NDA or maybe even a non-disparagement agreement. But of course, there's no explanation. You have to treat this as "creative non-fiction" (which is a genre all in itself)

In any case, I enjoyed the book --- the author's voice is fun to read, but I can't help but take it all with a large dose of skepticism.

2026 Mallorca Trip Report


From April 4th to April 12th, I took my family to Mallorca for a fixed based cycling-oriented vacation. Joining us was the crew from last summer’s bike trip—Arturo, Mark, Stephan and Otto Ellner, who were also joined by the rest of the family, Rosie and Benjamin. At the last-minute, Joe Chung, who went to college with me decided to come, though a few later than the others.

Bowen's bike suffered a broken derailleur cable and a flat tire that was worn out and replaced during the trip. Joe Chung's rental suffered from an unreproducible intermittent failure in the power delivery. Because it was a fixed based tour, everyone did varying amounts of riding, but I got in 296 miles and 24,300' of climbing in 6 days.

This post contains all links to videos, photo albums, and the day by day trip report.

Review: Lies My Teacher Told Me

 Lies My Teacher Told Me is about the way history is taught in American classrooms. In many ways it's also about the ways history is not taught in those same classrooms. In particular, the textbooks used in history classes come in for particularly (and well deserved) sharp criticism:

In 2005, for example, the Pew Research Center found that 62 percent of Republicans agreed with the statement, “Poor people today have it easy because they can get government benefits without doing anything in return.” Twenty-seven percent of Democrats also agreed. Such responses can only come from people who have neither had a conversation with a poor person nor imagined their economic and social reality—yet somehow imagine they know enough to hold an opinion. Educated people are more likely to venture such ill-informed opinions.24 Education does not have this impact in other areas of study. People who have taken more mathematics courses are more proficient at math than those who have not. (kindle loc 7496)

 The book starts with a provocative question: what was Helen Keller famous for, other than being blind and deaf but managed to teach herself how to read and write? I found myself unable to answer that question, and in fact, history books deliberately left out her achievements --- she was a socialist activist! Similarly, President Woodrow Wilson was an extremist socialist who re-introduced segregation to the White House, but that fact is never mentioned in the history books, where he was treated as a hero for attempting to start the league of nations.

The book then goes on to eviscerate various typical American founding myths, such as the idea the Christopher Columbus was uniquely smart to believe that the world was round --- that fact was in fact common knowledge. The book points out:

Columbus is not a hero in Mexico, even though Mexico is much more Spanish in culture than the United States and might be expected to take pride in this hero of Spanish history. Why not? Because Mexico is also much more Indian than the United States, and Mexicans perceive Columbus as white and European. “No sensible Indian person,” wrote George P. Horse Capture, “can celebrate the arrival of Columbus.”90 Cherishing Columbus is a characteristic of white history, not American history. (kindle loc 1691)

This telling of history as the heroification of famous Americans, the author points out doesn't do justice to the heroes or to Americans. By not showing that Abraham Lincoln struggled with racism himself, there's also no appreciation that he did work hard (and ultimately sacrificed himself) to eliminate slavery. 

In 1863 Lincoln desegregated the White House staff, which initiated a desegregation of the federal government that lasted until Woodrow Wilson. Lincoln opened the White House to black callers, notably Frederick Douglass. He also continued to wrestle with his own racism, asking aides to investigate the feasibility of deporting (euphemistically termed colonizing) African Americans to Africa or Latin America...Saving the Union had never been Lincoln’s sole concern, as shown by his 1860 rejection of the eleventh-hour Crittenden Compromise, a constitutional amendment intended to preserve the Union by preserving slavery forever.32 Not one author explains the political context or the intended audience for the Greeley letter. Nor does a single textbook quote Lincoln’s encouragement that same summer to Unitarian ministers to “go home and try to bring the people to your views,” because “we shall need all the antislavery feeling in the country, and more.” If they did, students would understand that Lincoln’s response to the issue of slavery in America was hardly indifference. (kindle loc 4096-4121)

The book covers many more topics in great detail, including the nadir of anti-black racism, and how many history books written during that period could not make sense of the anti-slavery movement, and those templates carry over till today. As a result, we still have large numbers of educated Americans claiming that the civil war was about states rights, or that it was about economics, or continuing to spread the myth that black people actually enjoyed being enslaved and had a good life being slaves!

By pretending that the US had overcome racism and conveniently forgetting about the period between  Woodrow Wilson and the post-civil rights era, the author points out that it also glosses over what the country's greatest achievements were:

 Antiracism is one of America’s great gifts to the world. Its relevance extends far beyond race relations. Antiracism led to “a new birth of freedom” after the Civil War, and not only for African Americans. Twice, once in each century, the movement for black rights triggered the movement for women’s rights. Twice it reinvigorated our democratic spirit, which had been atrophying. Throughout the world, from South Africa to Northern Ireland, movements of oppressed people continue to use tactics and words borrowed from our abolitionist and civil rights movements. The clandestine early meetings of anticommunists in East Germany were marked by singing “We Shall Overcome.” Iranians used nonviolent methods borrowed from Thoreau and Martin Luther King Jr., to overthrow their hated shah. On Ho Chi Minh’s desk in Hanoi on the day he died lay a biography of John Brown. Among the heroes whose ideas inspired the students in Tiananmen Square and whose words spilled from their lips was Abraham Lincoln.81 Yet we in America, whose antiracist idealists are admired around the globe, seem to have lost these men and women as heroes. Our textbooks need to present them in such a way that we might again value our own idealism. (kindle loc 4457)

I learned lots and lots in this book, highlighting passage after passage. I smile every time Professor Loewen proudly proclaims that teenagers write to him about using this book to heckle their history teachers from the back of the class. I will say that I learned more about American history from this book than from an entire semester at Berkeley taking an American history class to fulfill a social studies requirement.

Highly recommended.

April 5: Santa Magdelena



To my surprise I actually slept a bit (just as I had slept a bit on the plane as well) and woke up only at 4:30am. By 5:30am, Boen was up and bouncing, so rather than have him annoy everyone else I took him downstairs to the lobby and asked if we could start assembling the bikes. The night receptionist felt sorry for me and told me that I could assemble the bikes indoors as it was cold, but that if anyone started trying to use the lobby, I had to give them room. I happily assented.


First to come together was Xiaoqin’s bike, because that was where all the tools were—her bike was by far the lightest, so her bike box had the capacity to store tools, an extra chain, and lubricant. After that, I assembled my bike, followed by Bowen’s, and then Boen’s which was the easiest—since it was too heavy to put into a Trico hard case without exceeding the 23kg weight limit, we opted to use the bike box in the garage left from when we had purchased the Lynskey GR300. Boen’s bike was so small that all we had to do was to remove the pedals, remove the handlebars from the stem, and the rear derailleur, and the front wheel, and everything fit into the box. We did not even have to lower the seatpost or remove it from the frame!


By the time I finished, the breakfast room was open. We parked the bikes at the bike shop and put the empty boxes back into the luggage storage area and ate a breakfast. After all that, a change to bike clothing and we were ready to ride! All this time Arturo and Mark had been texting us about their progress, but they in fact only got to the hotel just as we departed on our ride.


I’d never been in this part of Mallorca before, and had picked out a gentle ride with two out and back climbs. Bowen wanted to skip them but had refused to load the route onto his bike computer, so he ended up doing the first (and prettiest) out and back climb to the start of the Victoriax hike parking lot. The day was gorgeous and the mediterranean looked as blue and beautiful as the Pacific Ocean does in California. Once back in the town of Bonaire, the route took us on what I consider classical Spanish roads—narrow single track roads lined with stone walls with next to no traffic and occasional views of beautiful flower fields. The day was warm but not too hot and the occasional sea-breeze felt refreshing.


Sadly enough, we had to ride through Playa du Muro, the super-touristy resort strip. However, the silver lightning was that this gave Bowen a chance to buy new sunglasses for his ride. We then exited on a main road. Since the prevailing wind was from the West, this meant we were hitting a headwind. The going was tough since the wind was light. The best feature of Mallorca is that there are cyclists everywhere—every day is  like a century ride. No matter where you look and which direction you’re riding, there’s a paceline of cyclists going this way and that.


At one point a group of women passed us and we jumped on the paceline, being disappointed when a couple of kilometers down the road they veered off into another direction. Bowen had fallen off the pace, however, as we skirted around Sa Pablo and we stopped often to let him catch up.


We eventually made it to Santa Magdalena, the start of the second out and back climb. The scenery wasn’t uninspiring, but Xiaoqin decided that since we were there anyway we might as well climb it. Bowen, Boen, Stephan, and Otto waited while we did the 30 minute 3km, 200m climb. It was a very pleasant climb, gentle in grade like in most of Mallorca.


When we got to the top I realized we should have made everyone do the climb as there was a very highly rated cantina on top! Nothing to do but to descend and then find another restaurant. It was already 2:30pm, so the other restaurant we found was already fully booked and refused to seat us! Instead, we found a supermarket and had a supermarket lunch before starting to ride back.


This time, we had a tailwind instead of a headwind and it was very pleasant going. We’d gotten a text from Mark and Arturo that they had abandoned the ride past Playa du Mura, since the headwind had strengthened. Our ride back along a designated bike route was nice, and at one point when the route deviated from the GPS track I had laid down ages ago we decided to just use the bike route. In fact, I turned off route following and used my Edge’s 840 instead, which gave us a short cut to our hotel.


Arriving back at the hotel at 4:30pm, Boen and I took a quick dip into the unheated swimming pool and we decided we had better options than being cold in a hotel pool for the rest of the trip.

Over dinner, we marveled at how the food was better than Miralago’s. Going back to the hotel room, we went to bed early hoping that the jet lag would be kind to us again.

Prologue: April 3-4 San Francisco to Club Del Sol, Port de Pollenca

 
Packing our bikes the day before, we got onto the plane and arrived in Copenhagen before transiting to the Mallorca flight. Unlike other airlines, rather than make us take the bikes to oversized luggage, the airline took the bikes directly at the bag drop and told us it would be checked all the way to Palma. The flight was uneventful despite a late start, and the dreaded EES system while slow, was no big deal as we walked quickly to the passport control and were close to the beginning of the line. They took pictures and fingerprint and stamped our passports.

Arriving at Mallorca, the first thing we saw when we exited our gate was a picture of cyclists riding! That put me in a good mood right away. SAS did a good job on the bikes, which arrived at the same time we did in luggage claim.


As promised, the hotel’s taxi operator met us at the exit to the baggage claim, and led us straight to the shuttle which had a trailer just for our bike boxes. He helped me put all the boxes in the trailer, and we got in and he drove us all the way for 115 Euros.

For this trip, we’d elected to stay at Club Del Sol, which was exactly in between Port Pollenca and Alcudia. You get a 10% discount for booking fairly early, and we’d booked half pensions for the entire week. Stephan and his family had already arrived a few days ago, since they were based out of Germany. In fact, they’d already ridden the Cap Formentor, which was the lighthouse ride I’d missed the last time I was on the island in 2019.

We’d arrived too late to put together the bikes, plus Xiaoqin and Bowen were hungry so they went to dinner at the hotel’s buffet while I checked us in. The hotel’s bike shop was already closed, but we were allowed to store our bike boxes at the hotel’s luggage room. We went to bed, with me dreading the impending jet lag.

Review: Lone Wolf and Cub: The Gateless Barrier

 The Gateless Barrier is book two in the Lone Wolf and Cub series. This volume is just as violent and bloody as the previous book, and the adventures the father and son go through make it quite clear that the protagonist is not a hero. Each story can be independently read like the old style TV episodes, so there's no character development.

In one episode, Ogami Itto is asked to kill a Buddhist priest. He tries to do so and discovers that he can't, yet the priest gives him hints that he first has to understand Buddha nature in order to kill him. The guy actually goes and meditates in the mountains for days in order to understand Buddha nature and successfully assassinates the priest. There's of course a bunch of things wrong with this, especially since Buddhist teachings prohibit killing (many Buddhists are vegetarians). In any case, these stories demonstrate something of Itto's character, but ultimately the effects of all that killing never seems to affect him. In another story, he abandons his son in a cave after an avalanche has buried the entrance in favor of his mission, saying that if fate wills his son will live and he will come back to rescue Daigoro.

Definitely a man with dedication to his mission!

Review: Miracle Children

 Miracle Children is the story of T. M. Landry College Prep, a prep school for black children that became famous on social media to sending children to top Ivy League schools, including Harvard, Brown, and Cornell. It was then later discovered that the entire school was a sham, fabricating transcripts in place of classes, and teaching applicants to lie about their life experiences in order to make a more compelling application.

The book effectively reveals that the "Holistic admissions" process is a scam. There is simply no way for any school to effectively vet that what candidate submit as essays are the truth, nor do they actually care. In fact, these schools do not actually care about academic excellence or actually education:

“Princeton is a rich man’s college,” the university’s president Francis Landey Patton told the faculty when they complained about students’ behavior. “Rich men do not frequently come to college to study.” After Woodrow Wilson replaced Patton in 1902, vowing to raise academic standards, his wife quipped to The New York Evening Post that her husband was trying to destroy “the most agreeable and aristocratic country club in America by transforming it into an institution of learning.” But prep school students knew their success was ensured, regardless of how little they worked; in fact, in the early 1900s, more than half the boys admitted to Harvard and Yale and two-thirds of the boys admitted to Princeton had failed the entrance exams...Harvard capped its number of incoming freshmen, limiting the intake of students who passed the entrance test. Unable to take every academically qualified applicant, Harvard began to weigh non-academic qualities as part of the admissions process. It emphasized the importance of athleticism and good character to help maintain aristocratic, if not meritorious, classes. College interviews and feeder schools were all the more essential as admissions tools, as they helped officials weed out academically gifted but undesirable students. Wilbur Bender, the Harvard dean of admissions in the 1950s, argued for admitting students “with IQs well below others” because they became business executives, governors, and presidents, “our most distinguished and useful graduates.”(kindle loc 1109-1115)

What allowed Mike Landry to get away with all this for years was that Louisiana effectively allows private schools to be outside the jurisdiction of the department of education. This was because of segregation. By putting private schools outside of the jurisdiction of public supervision, these schools could discriminate as much as they liked, allowing parents to keep their white children from being forced to mingle with black children. However, that meant that Mike Landry's abuse of children or effective non-teaching of any kind of curriculum (later on, he focused on recruiting higher performing students rather than teaching the kids who joined at lower grades) could not be punished.

The elite college admissions offices are not setup to actually read applications very carefully:

In cases where the applicant attended a feeder school or one that admissions counselors have visited, the readers rely heavily on notes about those schools. “During my time inside admissions offices,” Selingo wrote, “I quickly discovered that the unit being evaluated was less often the applicant than the applicant’s high school.” Selingo cited a study by an admissions consulting firm that found that of 130,000 applicants to a brand-name college over a decade, just 18 percent of high schools were responsible for 75 percent of applications and 79 percent of acceptances. (kindle loc 2497)

What's even more damning was that after the fraud came out, the Ivy League schools closed ranks and refused to admit that they had done no vetting. They defended their admissions of students who had actively lied on their applications so the whole facade they had created about admitting "deserving" students had fallen apart.

 The Landrys “were selling to the colleges this perfect-package student, and to the parents, they were selling hope.” But colleges were also seeking out up-from-nothing tales, especially among minority candidates, and helping to create the conditions for a place like T.M. Landry to thrive. “The reality is the colleges weren’t interested in merely mortal children,” Stancil said. “They wanted miracle children.” The colleges involved defended the students they had accepted, continuing to support them even after the Times ran accounts of the Landrys’ abuse and fabrications. Wellesley said that the T.M. Landry graduates were “thriving and engaged.” George Washington University was confident that those who had been admitted “have the capability to succeed and graduate.” Harvard, Brown, Yale, and New York University also defended their students (kindle loc 2923)

After you've read this book, you'll wonder why elite schools in the US have the reputation they do. Recent surveys about how Americans are losing faith in the value of a college education start to make sense.

Review: The Anthropocene Reviewed

 The Anthropocene Reviewed is a book full of random reviews written by John Green. I was, of course, uneasy about reading another piece of non-fiction by him, given my one experience with his non-fiction left me feeling dumber for having read it.

Fortunately, this book avoids all the weaknesses of Everything is Tuberculosis. For one, every essays is relatively short, no more than 3-5 pages, essentially a blog post or short podcast, which is a format that enables any competent writer to hide his lack of knowledge about any topic.

Secondly, since he picks essentially random things to write about, and frequently the title of the topic is only a jumping off point to either a different point that caught Green's attention or for Green to provide some sort of autobiography, the human interest side-stories that would annoy me in a longer piece of work doesn't annoy me here. I will note that in the middle of this book, I had to take a break to read another book as a palette cleanser --- even in this format, I can only cope with unadulterated non-fiction Green for 100 pages or so at a time.

I learned that he settled down in Indianapolis, but that Kurt Vonnegut was also from there. He did note that Vonnegut moved away as soon as he could and never returned:

Indianapolis’s favorite literary son, Kurt Vonnegut, wrote that one of the flaws in the human character “is that everybody wants to build and nobody wants to do maintenance.” Home ownership was all maintenance. There were always window treatments to install and light bulbs to change. The water heater kept breaking. And most of all, there was the lawn. God, I hated mowing the lawn. The lawn and the mini-malls of 86th and Ditch became the two poles of my resentment. I couldn’t wait for Sarah to get a job somewhere else. (kindle loc 2163)

There was one particularly poignant story in which he discusses being on call as a trainee chaplain when he's asked to  serve when a badly burnt little boy of 3 came in. He described the story as one of the contributors to him quitting his career as a chaplain to become a writer, but then he finds out later that the boy survived.

The voice of the book is unaffected, at times sensitive, and at times very contemporary bro-like. Green seems to be an interesting character. I'm afraid to watch his youtube videos or podcasts for fear that I won't like him very much if I see or hear him instead of reading him.

In any case, I had fun reading the book. The star rating (1-5 stars) is kinda used weirdly. I give them book 3.5 stars.

Review: The Elements of Marie Curie

 The Elements of Marie Curie is a biography of the famous two time Nobel prize winner. It's a thorough, event by event description of her life. What's clear to me is that she overcame a lot of obstacles and prejudices to become who she was, but the price was her health. Of course, nobody studying radiation at that time didn't know it was dangerous. In fact, one of the first applications was in medicine, using both X-rays and for radiation therapy.

What I didn't like about the book was the lack of information about how Curie approached the deaths of her lab employees --- by the time they started dying she should have realized that radition was dangerous. We never get any insight in the book about what she thought of it. Similarly, while we see how she crossed paths with many famous scientists, the book is very light on the details of what they discussed.

What Curie did during world war one was well documented in this book, but very little about the second world war. I kept reading in the hopes of getting more out of the book than I eventually did but got to the end with precious little additional insight.

Re-read: The Magician's Land

The Magician's Land is the third and final book of The Magicians trilogy. Following directly from The Magician King, the book starts with Quentin drawn into a heist. The heist, of course, goes horribly wrong, and in the mean time, in Fillory, the earthborn royalty discovers that Fillory is dying.

By the time everything weaves together, we get a reveal from Rupert Chatwin, and Quentin successfully resurrects Alice (I'd forgotten about this from the first read --- and the scene is faithfully replicated in the TV show as well), and discovers the secret to rejuvenating Fillory.

The writing style is just as bad as ever for the series, but for a change the plot doesn't suck, and a large part of the book is actually coherent, being in Rupert Chatwin's voice instead of Lev Grossman's omniscient 3rd party.

I enjoyed this book quite a bit more than the other two. I don't think the series will ever become a classic fantasy series, but it's quirky enough to deserve your time.

Review: The Haywire Heart

 One of my colleagues died in 2024, supposedly during a bike ride. The guy was fit, frequently passing me as though I was standing still, and the family (understandably) didn't disclose many details about what happened other than it was a sudden cardiac event.

I ran across an Outside article about Leonard Zinn getting into trouble because of years of endurance training. This was more fully documented by a book, The Haywire Heart. The book fully acknowledges that there can be no final medical study on whether excessive endurance training will cause you to die or get really poor medical outcomes. That's because you can't do a randomized blinded trial! On the other hand, intuitively we all understand that overdosing on any kind of medicine (and exercise is frequently listed as a medicine) can (and does) kill you.

The book starts with a description of what the heart does, and how both the muscular and electrical systems work. It's amazing how much the heart does, even in  sedentary person:

the heart produces as much energy in a single day as a 100-kg boulder does while falling from a building 383 feet tall (or as much energy as it would take to lift that boulder up to that height). That would leave a big dent in the sidewalk; 15 states in America don’t even have a building tall enough to do this experiment! The mechanical efficiency of the heart is less than 10 percent,9 so the heart will demand over 10 times as much energy (in Calories) as it produces, or in this case, 10 × 115,000 J = 1,150,000 joules in a day, or 1.15 × 106 J × 0.239 cal/J × 10-3 Cal/cal = 275 Calories. In other words, your resting heart requires about one Clif Bar per day in order to keep ticking. (page 43)

 The book has scattered throughout articles about various athletes who've succumbed to over-exercise syndrome. Some of these (including Dave Scott, multiple ironman winner) you might have heard of. The book describes how hard it is for athletes to get appropriate attention and medical care from doctors:

Most doctors don’t know the sensation of being in a road race, criterium, or time trial. They’ve never been in the gutter because of a crosswind, saying to themselves, Ten more pedal strokes, just do it for 10 more pedal strokes. Hold that wheel! Don’t let go! Most doctors don’t know the effort it takes to bridge across to a breakaway. When normal people feel the sensation that a curtain is closing in on their peripheral vision, they turn the tension down on the exercise bike or reduce the speed of the treadmill. They pull the plug on the pain. They are normal. Competitive athletes are not....at a European heart meeting where a doctor presented a case including an ECG that showed a heart rate of 32 beats per minute. The presenter withheld the fact that the ECG belonged to an athlete. He then asked the audience which treatment they would recommend. The audience response system, an automated way to ask the audience questions and compile the most common answers, revealed that a significant number of attendees recommended a pacemaker. Before the first presenter could clarify things, a fiery senior presenter stepped to the microphone and chastised the audience. He was visibly angry. He used the example of five-time Tour de France champion Miguel Indurain, who famously boasted a resting heart rate of 28 bpm. (page 144, 146)

 The book acknowledges the complete lack of data and studies. For instance:

research paper from Denmark garnered significant attention in the lay press because it boldly concluded there was a U-shaped association of running and death rate.62 That is, light and moderate joggers had lower death rates than sedentary controls, but strenuous joggers had death rates similar to the sedentary controls. This paper, with its common-sense conclusions, suffered from a severe statistical problem: The group of vigorous runners included only 36 of more than 1,000 runners in the study. Although the authors reported that vigorous runners had nearly twofold higher death rates, the confidential intervals were wide, ranging from a 50 percent lower death rate all the way up to an eightfold higher death rate. You simply cannot draw any conclusions from this sort of data. (page 111)

What's interesting is that the book doesn't recommend running out and getting tested immediately! That's because there's a huge risk of over-treatment! The book has a horror story in which someone got an MRI and that turned into a series of tests culminating in a completely unnecessary procedure that did permanent damage to that person's heart!

OK. What are you supposed to do? Well, you're supposed to listen to your body. By the way, that's a dangerous advice when you're reading this book, because after reading all these horror stories I found myself more sensitive than usual and can easily believe that I would hallucinate issues even when there were none. I'm very grateful now that my Garmin connect frequently tells me that I'm too lazy to have sufficient "high aerobic" or "anaerobic" workouts! (On the other hand, my 23andMe results once told me I hada high chance of Atrial Fibrillation)

In any case, the book recommends a few supplements that haven't been shown to do any harm (CoQ10, magnesium). They also recommend backing off a bit on the ultra-high-intensity events and intervals that people who are training for hard races do. I think that probably makes sense --- I observed that last year's tour was particularly easy, and I ended the tour stronger than at the start because I was resting so much. That's probably a much healthier tour than a full on, push yourself to the limit every day day after day!

The book's worth reading, and then giving yourself some time off to avoid being a hypochondriac before taking its advice to heart. Fortunately, most people are unlikely to ever push themselves to hard for whom exercise overdose is even a potential problem.
