I'll buy a robot that can put fitted sheets and fold every piece of laundry no matter how contorted/inside-out it is. Till then, they're just gimmicks. Also, it should have legs.
Brilliant answer. It is not intuitive that while it takes the same energy to heat an object from 0 C to 1 C as it does from 1 C to 2 C, it takes 1/3 of the energy to speed up an object from 0 kph to 1 kph than it does from 1 kph to 2 kph.
Beautiful! I noticed this on the chess ratings distribution on Lichess: players like to cross a nice multiple of 100 and make an extra effort to avoid dropping below if they can: https://imgur.com/a/Db7fQdX
Physicist here. I don’t buy some of these distinctions, like the chirality. Chirality is an observable, it’s like saying there are two photons because they can come in two polarizations, but polarization is not an inherent property: it depends on how we measure it. So I could describe any photon in the left/right chiral basis just as well as in the vertical/horizontal basis or any two antipodal points in the Poincaré sphere, so which is the “right one”? Neither. Spin on the other hand (which is where polarization comes from) is well-defined for any photon and it’s always 1 (the astute reader will wonder why the projection of spin 1 does not take 3 eigenvalues 1,0,-1 and it’s because photons are massless so the 0 projection never occurs because there is no rest frame for massless particles).
Yep, that’s what happened to my wife… she started rhythmic gymnastic and ballet at 4 in Eastern Europe in the 90s with a brutal coach, had to stop at 12 for an injury, and she has been having chronic pain and arthritis since she was 17. Anything taken to the extreme can have lifelong consequences.
Good for you to have figured this out! This is how I always work, and I am as productive as I can be because I only do what's on top of my mind. I've also learned that if something is never on top of my mind it's because it's not worth doing, so it gets filtered away automatically.
I probably am in a privileged position to be able to do this (greenfield research in the private sector), but I just love it.
It did happen quite often to have to retake a few exams. Some students could never clear some particularly hard ones. But I have never heard any professor ever complain about it. Nobody wants a struggling student to finally succeed more than the professor who has to keep failing them.
I can’t help comparing this to the system I grew up in (Italy), which is vastly different and it seemingly produces very good graduates.
University was free and there was no test for enrolling in STEM degrees, and you could retry exams every semester as much as you wanted to. But goddamit exams were HARD and if you weren’t prepared enough you would keep failing until you gave up.
We weren’t entitled because we weren’t paying customers.
Also because Italy is Italy we had unlimited beer and wine on tap in the canteen. For real.
