  • This reminds me of a one of Zeno’s Paradoxes of Motion. The following is from the Stanford Encyclopaedia of Philosophy:

    Suppose a very fast runner—such as mythical Atalanta—needs to run for the bus. Clearly before she reaches the bus stop she must run half-way, as Aristotle says. There’s no problem there; supposing a constant motion it will take her 1/2 the time to run half-way there and 1/2 the time to run the rest of the way. Now she must also run half-way to the half-way point—i.e., a 1/4 of the total distance—before she reaches the half-way point, but again she is left with a finite number of finite lengths to run, and plenty of time to do it. And before she reaches 1/4 of the way she must reach 1/2 of 1/4=1/8 of the way; and before that a 1/16; and so on. There is no problem at any finite point in this series, but what if the halving is carried out infinitely many times? The resulting series contains no first distance to run, for any possible first distance could be divided in half, and hence would not be first after all. However it does contain a final distance, namely 1/2 of the way; and a penultimate distance, 1/4 of the way; and a third to last distance, 1/8 of the way; and so on. Thus the series of distances that Atalanta is required to run is: …, then 1/16 of the way, then 1/8 of the way, then 1/4 of the way, and finally 1/2 of the way (for now we are not suggesting that she stops at the end of each segment and then starts running at the beginning of the next—we are thinking of her continuous run being composed of such parts). And now there is a problem, for this description of her run has her travelling an infinite number of finite distances, which, Zeno would have us conclude, must take an infinite time, which is to say it is never completed. And since the argument does not depend on the distance or who or what the mover is, it follows that no finite distance can ever be traveled, which is to say that all motion is impossible. (Note that the paradox could easily be generated in the other direction so that Atalanta must first run half way, then half the remaining way, then half of that and so on, so that she must run the following endless sequence of fractions of the total distance: 1/2, then 1/4, then 1/8, then ….)













  • This reads like an absurd Kafkan affair. Here’s a quote from the article:

    Over those same years, however, Gambaryan has taken an even more unlikely path: In 2021, he left the IRS to take a job as the head of investigations at Binance, the world’s largest cryptocurrency exchange—a move seen widely as driven by Binance’s belated attempt to clean up its own widespread use for money laundering, which led the company to pay a $4.3 billion criminal fine to the US government last year. When Nigeria followed that fine by accusing Binance of similar criminal misconduct and devaluing the country’s national currency, it was Gambaryan who was invited to Abuja to negotiate with the Nigerian government earlier this year. Instead, the Nigerian government detained Gambaryan, took his passport, and has now jailed him for over six months, charging him with money laundering and tax evasion as a proxy for his employer.

    This reads like a total farce. What could possibly be the end goal for the Nigerian government here? Do they just want someone in handcuffs for the press ops to cover up their own incompetence?
