TIL: The coastline paradox and Baader-Meinhof phenomenon

“Uh, what?” you say.

A few weeks ago, I read a post on Hacker News about something called “the coastline paradox.” Despite my geology background, I hadn’t heard of this before.

The measured length of the coastline depends on the method used to measure it and the degree of cartographic generalization. Since a landmass has features at all scales, from hundreds of kilometers in size to tiny fractions of a millimeter and below, there is no obvious size of the smallest feature that should be taken into consideration when measuring, and hence no single well-defined perimeter to the landmass.

Essentially, the smaller unit of measurement you use to try and measure something with a fractal pattern, the longer it becomes.

So, I’m currently reading a book called “Reading the Rocks” by Marcia Bjornerud and there is an entire section devoted to the coastline paradox, which I just learned about.

Mandelbrot’s point was simple: If you use a very long stick to measure a coastline, you will capture the broadest arcs but miss the fjords, firths, and coves, and you will conclude that the coastline is not terribly long. As you use shorter and shorter rulers, however, the coast actually stretches. Mandelbrot named such stretchy features fractals…

Neat!

This brings up the second TIL: What is the phenomenon called when you hear something for the first time and then suddenly start seeing or hearing it everywhere?

It’s the Baader-Meinhof phenomenon, also known as the frequency illusion:

The frequency illusion (also known as the Baader-Meinhof phenomenon) is a cognitive bias in which a person notices a specific concept, word, or product more frequently after recently becoming aware of it.

Well, here’s to seeing more coastline paradoxes.

My 2023 Reading List

I didn’t do a great job of reviewing every book I read this year, but still read a good number of books this year. My Goodreads goal was 24 books and I hit 30.

This is down from 40 in 2022, 56 in 2021, and 60(!) in 2020. Kind of an interesting correlation between the pandemic years and what has happened as we’ve come out of various lockdowns (e.g., more activity outside is less time reading inside).

Anyway, this year’s list of books is below. My favorites were The Making of the Atomic Bomb and Tracers in the Dark. My least favorite was easily Blindsight.

Book Review: The Explosive Child

This was one of the first books I’ve read that so specifically addressed the unique difficulties we’ve been encountering with one of our kids, and the insight it provided was eye-opening and validating.

Dr. Greene’s descriptions of some scenarios people encounter at home were strikingly accurate. It kind of shook me up with how absolutely on the mark some of these descriptions and scenarios were. For me, the scenarios depicted weren’t just abstract concepts but felt like real-life situations that played out in our home.

It had some interesting ideas and strategies for navigating situations that might cause these explosions that I can’t wait to try. Namely, a concept called “collaborative problem solving”, which involves validating your child’s feelings and concerns and then working with them to come up with a solution.

The book is refreshingly honest about the complexity of these challenges, acknowledging that there’s no magic solution or quick fix. Even though there is no silver bullet, it definitely gives me hope that the light at the end of the tunnel isn’t an oncoming train.

I found “The Explosive Child” to be an insightful and valuable resource.

Book Review: The Last Island by Adam Goodheart

A few days ago, I stumbled upon a Reddit post about someone taking a photo as they flew over North Sentinel Island. I can’t recall hearing about this particular island at all, so I popped into the comments to see what the big deal was.

As it turns out, this island has one of the last remaining un-contacted tribes on Earth. Oh! Now this is interesting. It’s especially relevant, because a recently released book dives into the history of this island.

The Last Island, by Adam Goodheart, documents the author’s journey to the Andaman Islands in the late 90’s and his attempt to see the island with his own eyes.

It’s a very quick read (272 pages) and I went through it in about 2 days. After the author sharing his initial experience with visiting the Andamans, he explores the history of British colonization of the archipelago, the attempts to convert (“save”) local tribespeople, and some of the exploitation and abuse that happened as well.

More recently, attempts to interact with native tribespeople in other parts of the Andaman Islands has given insight into various issues the tribes face as they integrate with modern society. Disease is obviously the biggest, but alcoholism plays a part as well:

They live now in a restricted tribal reserve at the southern end of the island; these onetime hunter-gatherers now depend largely on food supplied by the Indian authorities. Malnutrition rates, alcoholism, and infant mortality are reportedly high. In 2008, at least eight Onge men and boys⁠—almost a tenth of the tribe’s remaining population⁠—died after drinking the contents of a bottle that they had found on the beach, which they believed to be an alcoholic beverage; it was actually a toxic chemical solvent.

Through it all, a tiny little island located 20 miles off the coast seemed to defy these attempts. It’s partly due to the treacherous reefs around the island, and partly due to the fact that British colonizers saw nothing of value on the tiny island.

Calling the Sentinelese an “un-contacted” tribe is a bit of a misnomer, since there were various expeditions throughout the last 100 years or so that involved kidnapping (!), dropping off various gifts (coconuts, pots and pans), a shipwreck in 1981 (check it out on Google Maps!), and the misguided attempts of an American evangelical who illegally landed on the island in 2018 and was quickly killed by the inhabitants.

In 1956, the Indian government passed a law that prohibited visitors from coming in contact with the island (though as seen above, this has not been strictly enforced). In more recent times, the Sentinelese have taken a more protective approach (rightly so, considering recent history).

Via Wikipedia:

The Sentinelese have repeatedly attacked approaching vessels, whether the boats were intentionally visiting the island or simply ran aground on the surrounding coral reef. The islanders have been observed shooting arrows at boats, as well as at low-flying helicopters. Such attacks have resulted in injury and death. In 2006, islanders killed two fishermen whose boat had drifted ashore, and in 2018 an American Christian missionary, 26-year-old John Chau, was killed after he attempted to make contact with the islanders three separate times and paid local fishermen to transport him to the island.

Overall, I thought the book was an interesting look at the history of this area, and an exploration into our fascination with un-contacted tribes that still exist in the modern world and the way in which we tend to idealize them (and treat them in a similar way to the animals we see at the zoo or on a safari).

3/5 stars

Book Review: Leonardo da Vinci by Walter Isaacson

I recently finished Leonardo da Vinci by Walter Isaacson. I’ve long been intrigued by Leonardo and his seemingly limitless curiosity. I think I decided to finally pick up this book due to the release of another Isaacson biography that I don’t really have a desire to read — Elon Musk (cue booing sounds).

While I appreciated learning about Leonardo’s various endeavors and various aspects of his personal life, I found myself distracted by Isaacson’s narrative style. Maybe I’ve read too many of his books as of late (Benjamin Franklin, Einstein, Steve Jobs, Innovators, and Code Breaker), but I’ve found that his method of telling a biography has become somewhat repetitive.

That said, the book isn’t without its merits. The accounts of Leonardo’s projects, especially insights into various works such as his anatomical studies, the Last Supper and the Mona Lisa held my attention. These serve as reminders of da Vinci’s unique contributions to both art and science.

For those unfamiliar with Isaacson’s previous works, this biography might come off as more enlightening. But as someone who’s journeyed through his other books, there was a sense of “been there, read that.”

Overall, “Leonardo da Vinci” earns a 3 out of 5 from me. Informative, but perhaps not the standout biography of Leonardo I was hoping for.

Book Review: The Making of the Atomic Bomb by Richard Rhodes

The Making of the Atomic Bomb by Richard Rhodes captured my attention from start to finish. Going into it, I was fascinated by the idea of understanding the convergence of minds that led to the creation of one of history’s most powerful and controversial weapons. And of course, the recent buzz about the Oppenheimer movie contributed to this interest as well.

Rhodes doesn’t just delve into the technicalities of the bomb’s construction, which, on its own, would have been captivating. He masterfully presents the lives, backgrounds, and motivations of the characters involved.

A large part of the first third or so of the book digs into nuclear chemistry and the intense research going on to figure out these chain reactions. It was just absolutely fascinating.

What I found particularly interesting were the insights into the parallel efforts in Japan and Germany. It provided a unique view of the global race that was underway, further elevating the stakes and suspense of the story.

Throughout the book, there was this compelling juxtaposition: the brilliance of the minds at work against the backdrop of the impending devastation their creation would bring. It’s a testament to Rhodes’s storytelling that he managed to weave these narratives seamlessly.

“The Making of the Atomic Bomb” was a stellar read, and it easily gets a 5 out of 5 from me. For anyone curious about the people and the drama behind the science, this is a must-read.

Book Review: The Anthropocene Reviewed by John Green

I’m just going to start off and say that this was a beautifully written book and it really struck a chord with me.

The Anthropocene Reviewed is a collection of essays adapted from a number of episodes from John Green’s podcast. I hadn’t actually heard of the podcast before, so the material in this book was new to me. Each chapter in the book is a review of a different subject on something created by or affecting humankind.

Everything from Dr. Pepper and Canadian geese to the Notes app on our phones and the Internet in general. The chapters are part review and also part historical research. I just loved it. I think part of the reason I enjoyed this book was because we’re roughly the same age. So, a number of his thoughts and experiences roughly correlated with my own. “Are you me?!” is something I thought a number of times in the book.

Take, for example, his review of Super Mario Kart:

I was in tenth grade when Super Mario Kart was released, and as far as my friends and I were concerned, it was the greatest video game ever. We spent hundreds of hours playing it. The game was so interwoven into our high school experience that, even now, the soundtrack takes me back to a linoleum-floored dorm room that smelled like sweat and Gatorade. I can feel myself sitting on a golden microfiber couch that had been handed down through generations of students, trying to out-turn my friends Chip and Sean on the final race of the Mushroom Cup.

We almost never talked about the game while playing it—we were always talking over each other about our flailing attempts at romance or the ways we were oppressed by this or that teacher or the endless gossip that churns around insular communities like boarding schools. We didn’t need to talk about Mario Kart, but we needed Mario Kart to have an excuse to be together—three or four of us squeezed on that couch, hip to hip. What I remember most was the incredible—and for me, novel—joy of being included.

That rang so true.

Another chapter of the book reviews Canadian geese. Fun fact: growing up, my mom had a flock of (non-Canadian) geese in our yard. The wings were clipped, so they couldn’t fly away. But I have distinct memories of them running after me in the backyard, pecking at my legs and back. And that awful honking. It’s no wonder that I really think that geese are the worst animals in the world.

But even though Canada geese are perfectly adapted to the human-dominated planet, they seem to feel nothing but disdain for actual humans. Geese honk and strut and bite to keep people away, even though they’re thriving because of our artificial lakes and manicured lawns. In turn, many of us have come to resent Canada geese as a pest animal. I know I do.

The Anthropocene Reviewed is of my favorite books that I’ve read this year.

The Anthropocene Reviewed by John Green

Book Review: Moonwalking with Einstein by Joshua Foer

Josh Foer’s book starts out by looking into an esoteric competition featuring mental athletes competing in various memory competitions. Along the way, he discovers interesting mnemonic tricks for memorizing various types of things and follows a group of people who frequently compete in these events. With dedicated practice, he uses this effort to win the United States Memory Championship just a year later!

While Foer’s book documents his journey in becoming a mental athlete, it also features a number of interesting asides that dive into the latest research in memory and explores how and why humans are good (and not so good) and remembering various types of things.

The book opens with what seems like a non-sequitur:

“Dom DeLuise, celebrity fat man (and five of clubs), has been implicated in the following unseemly acts in my mind’s eye: He has hocked a fat globule of spittle (nine of clubs) on Albert Einstein’s thick white mane (three of diamonds) and delivered a devastating karate kick (five of spades) to the groin of Pope Benedict XVI (six of diamonds). Michael Jackson (king of hearts) has engaged in behavior bizarre even for him. He has defecated (two of clubs) on a salmon burger (king of clubs) and captured his flatulence (queen of clubs) in a balloon (six of spades). Rhea Perlman, diminutive Cheers bartendress (and queen of spades), has been caught cavorting with the seven-foot-seven Sudanese basketball star Manute Bol (seven of clubs) in a highly explicit (and in this case, anatomically improbable) two-digit act of congress (three of clubs).”

You read this and immediately think, “what?!” But! There’s a method to this madness. It’s a specific technique that Foer describes later in the book. He’s built a “memory palace” to make recalling a list of items easier. It’s something I hadn’t heard of before and is an interesting concept.

Foer describes a memory palace as:

“The idea is to create a space in the mind’s eye, a place that you know well and can easily visualize, and then populate that imagined place with images representing whatever you want to remember. Known as the “method of loci” by the Romans, such a building would later come to be called a “memory palace.”

[…]

When we see in everyday life things that are petty, ordinary, and banal, we generally fail to remember them, because the mind is not being stirred by anything novel or marvelous. But if we see or hear something exceptionally base, dishonorable, extraordinary, great, unbelievable, or laughable, that we are likely to remember for a long time.

The more vivid the image, the more likely it is to cleave to its locus. What distinguishes a great mnemonist, I was learning, is the ability to create these sorts of lavish images on the fly, to paint in the mind a scene so unlike any that has been seen before that it cannot be forgotten. And to do it quickly. Which is why Tony Buzan tells anyone who will listen that the World Memory Championship is less a test of memory than of creativity.

When forming images, it helps to have a dirty mind. Evolution has programmed our brains to find two things particularly interesting, and therefore memorable: jokes and sex—and especially, it seems, jokes about sex.

While there’s no secret to easily unlocking a flawless memory, I found this book really enjoyable to read and thought some of the techniques for recall were pretty useful.

As far as the title of the book goes — it ultimately has nothing to do with Einstein. It’s related to using a mnemonic technique he used for remembering a set of cards (in this case, a four of spades, king of hearts, and three of diamonds).

Moonwalking with Einstein, by Joshua Foer

Book Review: Columbine by Dave Cullen

The recent horrific (and all too frequent) school shooting in Uvalde is shocking, sickening, and absolutely impossible to understand. I can’t even begin to imagine what the parents of those children are even going through.

Dropping my kids off at school the day after this happened was especially emotional. I wasn’t the only parent wiping tears away from my eyes as we waved good bye to our little ones.

In an effort to try to understand more about these sorts of tragedies, I decided to read about the event (that I feel like) started this madness: the tragedy at Columbine.

I have a vague recollection of hearing about the news. I was in high school myself at the time, and I remember leaving school a bit early for a volleyball match against another school. As we were loading up the bus and getting ready to depart, I heard another student ask if anyone heard about “what happened at a high school in Colorado?”

At the time, we had little information and kind of just filed it away in the back of our mind.

It wasn’t until I got home later that night that I began to understand just how horrific it was. The media was quick to come up with scapegoats: music, video games, trench coats, loners who were bullied, etc.

We tried to comprehend it, even though we couldn’t. We also couldn’t imagine something like that happening again because it was so egregious. It was a random, unfortunate (and terrible) act, designed to inflict terror. We would move past it.

And we did… for a bit.

And then the school shootings kept happening. (And mass shootings in general.)


Dave Cullen’s book does a deep dive into the events around the massacre at Columbine — using journal entries and videos recorded from both the shooters and evidence sourced from the Jefferson County Sheriff’s Office. He creates a detailed timeline of the things that actually happened that day, and how the city has since tried to recover.

One of the things that stood out to me at first was how shockingly… normal Eric seemed. He had a lot of friends, got good grades, had girlfriends, and people generally had nice things to say about him. Deep down though, he was a true psychopath with a deep seated anger toward everything and everyone.

When he and Dylan were caught stealing electronic equipment from someone’s work van one night, they were assigned community service work and ordered to attend counseling services.

According to the counselors notes, he excelled at the program and always said the right things and displayed the right amount of humility and sorrow for what he had done. At the same time, he was writing in his journal at home about how much he hated the world and wanted everything to burn.

Eric was a full on psychopath in every sense of the term. A section in the book dives into this history of this psychological phenomenon.

Psychopaths are distinguished by two characteristics. The first is a ruthless disregard for others: they will defraud, maim, or kill for the most trivial personal gain. The second is an astonishing gift for disguising the first. It’s the deception that makes them so dangerous. You never see him coming. (It’s usually a him–more than 80 percent are male.) Don’t look for the oddball creeping you out. Psychopaths don’t act like Hannibal Lecter or Norman Bates. They come off like Hugh Grant, in his most adorable role.

In the wake of these mass shootings, people often talk about warning signs and mental health issues (but never the easy access to guns and the carnage they cause, because God forbid we ever talk about those). I myself have thought, “if only this person could have gotten therapy or been helped earlier, it might have changed things.”

Cullen digs into this with a simple answer regarding true psychopaths: it doesn’t work. An excerpt from the book:

Dr. Hare’s EEGs suggested the psychopathic brain operates differently, but he could not be sure how or why. […] Dr. Kent Kiehl wired subjects up and showed them a series of flash cards. Half contained emotionally charged words like rape, murder, and cancer; the others were neutral, like rock or doorknob. Normal people found the disturbing words disturbing: the brain’s emotional nerve center, called the amygdala, lit up. The psychopathic amygdalae were dark. The emotional flavors that color our days are invisible to psychopaths.

Dr. Kiehl repeated the experiment with pictures, including graphic shots of homicides. Again, psychopaths’ amygdalae were unaffected; but the language center activated. They seemed to be analyzing the emotions instead of experiencing them.

So what’s the treatment for psychopathy? Dr. Hare summarized the research on a century of attempts in two words: nothing works. It is the only major mental affliction to elude treatment. And therapy often makes it worse. “Unfortunately, programs of this sort merely provide the psychopath with better ways of manipulating, deceiving, and using people,” Hare wrote. Individual therapy can be a bonanza: one-on-one training, to perfect the performance. “These programs are like a finishing school,” a psychopath boasted to Dr. Hare’s team. “They teach you how to put the squeeze on people.”

To me, that was one of the most frightening passages in the book.

I don’t think this book helped me understand why these sorts of things continue to happen — can anything really do that? That said, it was a fascinating piece of investigative journalism that pieced together material from a variety of sources. I can’t say I enjoyed reading it (because the contents are obviously tragic and heavy), but I felt that it was interesting and informative.

Book Review: The Ministry for the Future by Kim Stanley Robinson

For me, this book was a bit of a slog to get through. I had originally started it early last year and had read pieces of it in fits and starts. It’s been partially read for nearly 12 months now, so I decided to try and finish it in earnest.

It’s an account of the near future, as drastic side effects due to climate change become more prevalent and catastrophic (the book opens with a heat wave in India that kills millions).

The story is told through a series of eyewitness accounts that take us across the world, detailing the effects of climate change and some of the (far-fetched and even fantastical) ideas people have to cope with it.

Some of the accounts and stories told by various characters are compelling, but a number of them are dry and uninteresting.

Eventually we get into current events and a discover a sort of utopia being created around the world to combat climate change together. Side note: the negative response of various groups of citizens and even some countries to the COVID-19 pandemic makes me think this sort of thinking is truly in the realm of fiction. Cli-fi if you will.

Anyway, I really couldn’t get into it. In general, I think I like the idea of Kim Stanley Robinson books more than I like reading them.

(That said, there are still a number of his other books on my bucket list that I will inevitably read.)
