Decoy Font 6 days ago

Nice! A few years ago during my PhD I had made a Mathematica notebook that would take two images, crop them to the same size, apply a high-pass filter to one (which keeps the small sharp details) and a low-pass filter to the other (which keeps the large blurry blobs) and then superpose them back together. It was a bit hit and miss because e.g. if the eyes of two people were not in the same location the illusion would kind of break, but for text with outlined fonts it was amazing. I made a large one that would read "SCIENCE" from afar and "WORKS" from up close and stuck it on my office door.

The Vespa at 80 18 days ago

In my 20s I tried with two other friends to raise some money from local businesses to sponsor a coast to coast trip in the US on our vespas (I had 1968 150 Sprint Veloce in red). It didn’t work out, but now that I’m in my 40s I understand it would have been a terrible idea ^^’

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.

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.
