  • The decimalization of money is its own fun history, with a lot of different countries undergoing their own transitions at different times.

    The Spanish dollar, which was the world reserve currency in its heyday, was divided into 8 reals (see how pirates used to refer to money in the form of “pieces of eight”) but issues with the supply of silver led to the introduction of the lesser real de vellón, which eventually settled at 20 to the dollar after over 100 years of uncertainty and confusion.



  • The animation is actually slowed down. Kinesin can take something like 100 steps per second. Each step is about 8 nm, and they’ve been observed to move 600-1000 nm per second.

    In reality it wiggles around in Brownian motion but the equilibrium of it “clicking” into place is so attractive that it keeps happening really fast.



  • it’s more when people are almost using the metric system then fuck it up, like the “Watt Hour” for measuring energy use.

    Energy is just so important to physics and engineering that it will be measured in whatever unit is most convenient to convert in that particular context: joules as the SI unit, watt hours for electricity usage, calories for certain types of heat or food energy calculations, electron volts in particle physics, equivalent tonnes of TNT for explosion energy, things like that.




  • There’s a book I read, Range by David Epstein, that really reinforces the idea that lots of experiences that don’t cleanly fit into a CV are still very valuable. The core idea is that late specialization makes for better specialists, because very few fields stand alone. Having contextual background makes it so that you can better mix and match cross disciplinary skills, with your own experience and knowledge of yourself, to be better at whatever it is you’re doing.

    The examples used in the book are Roger Federer (played many sports and didn’t specialize in tennis until much later than the typical pro), Django Reinhardt (never formally schooled in music but an amazing jazz guitarist even after he lost 3 fingers), Van Gogh (many failed careers before finding success as a painter), and a bunch of others.

    But the core principle is the same: the real world is messy and doesn’t boil down to simple factors, so having breadth is important when the system you come up in changes underneath your feet. The book also uses the counterexamples of Tiger Woods and the Polgar sisters who were dominant chess players, to describe how the fields of golf and chess give immediate, true, and objective feedback in a way that most of the world doesn’t.

    He was constructing his own languages and scripts in his teens, after having learned Anglo Saxon and Latin (and seeing how those fed into modern English), plus Esperanto.

    He traveled all over Europe in the summers between university semesters, taking in the different landscapes, cultures, and languages.

    He was a British Army Officer for World War I, leading units consisting of men from different backgrounds (class, education, trade) from his own. He devised a code system to bypass Army censors to keep his wife updated on his location and movements. And he experienced the horrors of being in the front lines of one of the most horrific wars in history.

    Then after the war he became an accomplished academic, worked on the Oxford English Dictionary, specialized in Middle English and Old English translations, and translated several major works (including the definitive translation of Gawain and the Green Knight).

    So by the time he started formally working on Lord of the Rings, he had built up such a rich set of experiences, skillsets, and knowledge that everything he knew was going into that world building.

    No way a 25-year-old could have written Lord of the Rings. He needed 20+ years of adult experience to get to the point where he could write it.





  • The humor mainly comes from overly elaborate execution of fundamentally simple ideas, so it’s usually pretty easy to summarize, even if the sheer amount of effort involved is so far outside the realm of plausible (or cost effective).

    The amount of effort that went into the Dumb Starbucks store, or the Michael Richards impersonator leaving a $10,000 tip, were mind bogglingly intricate ways to execute fundamentally simple big picture plans.

    His current show, The Rehearsal, really leans into that dynamic, too.


  • In an episode of Nathan Fielder’s Nathan for You, he once convinced a haunted house to try a gimmick that it starts off normal, but halfway in the staff and management freak out that one of the staff accidentally touched a guest, pulls them aside out of the haunted house into normal lighting, and a whole biohazard suit team and ambulance has to quarantine the guest for a bit in a series of escalating interactions that they’ve contracted some highly contagious and deadly disease, before they reveal that it was all part of the haunted house.

    Then a real lawyer is waiting at the end asking if they want to sue for emotional distress, because Nathan Fielder wants the haunted house to drum up publicity that it was so scary that they’ve been sued for it.


  • That’s basically what an HSA is.

    You sign up for a high deductible plan where you pay for your own medical expenses, but document them, up until you hit your out of pocket maximum ($8300 for individuals or $16600 for families), at which point your insurance kicks in to cover the catastrophic bills you typically won’t have in a typical year.

    Meanwhile, you are eligible to contribute $4300 per year for individuals or $8750 for families into an HSA, which has very favorable tax treatment (pretax money deposited, not taxed when taken out for health expenses, even after growing a lot), and allows you to invest everything above the minimum cash balance (varies by provider, usually something like $1000 or $2000).

    That way in a year you happen to hit a $1 million illness or injury you’re still covered against catastrophic financial loss, but you generally pay your own way with tax-deductible funds that you’re allowed to invest for growth.
