Train wheels and tracks have a surprising amount of science going on. (I never noticed they're subtly cone shaped, or the sinusoidal motion.)

Technology from the 1800s (which took a century to develop to _that_ level) can be surprisingly advanced. No wonder Russia was importing all those western rail components they're now running out of: this is not "blacksmith making horseshoes" level of design/fabrication tolerances.

Why Are Rails Shaped Like That?

@landley there's a well-known exception: BART

BART decided to try and take a tradeoff to reduce hunting oscillation, but as a consequence they ended up with the horrible noise (especially when not maintained well)

@r Half of Adam Something's channel is "oh no, techbros have badly reinvented trains again".

Tech Bros Invented Trains And It Broke Me

@landley heh, are "aerospace engineers" the techbros of the 1960s?

@r It's called "Nobel Disease": https://en.wikipedia.org/wiki/Nobel_disease

Every grifter knows most smart people are easy marks who think they're too smart to be fooled.

Highly educated people are MORE susceptible to Freddy Kruger's sister Dunning, because they mistake deep knowledge for broad knowledge. If you spent 30 years becoming the world's leading domain expert on boll weevil genetics, how hard could everything else be? People line up to hear you speak at trade conferences, why not solve politics for them
