I built a thing. It's notes and tasks. But not as a SaaS. Built it first for myself because I couldn't use apple notes at work, but then also for AI agents as a rich interaction surface between us both.

drewcsillagon How fast is quantum entanglement? Scientists investigate it at attosecond scale

Appreciate the reply! Now I have math and thinking to do :)

drewcsillagon How fast is quantum entanglement? Scientists investigate it at attosecond scale

First, I assume I’m missing some critical detail and am wrong somewhere.

Both the ERP, and the explanation of the CHSH with the difference being cos^2(theta) an isn’t that just Malus’s law? So in the case of the ERP experiment, if you fired single polarized particles at a polarizing filter at one angle or the other you still get cos^s(theta) as the difference without requiring entanglement, no?

That implies, in the case of entangled particles there is more than one dimension of “whatever” that causes the polarizing filter to “choose” whether to extinguish the particle on non-equal angles - like azimuth/elevation instead of just theta? It just seems to me that rather than disproving a “hidden variable”, it requires one?

Like I said, I assume I’m missing something and am wrong.

drewcsillagon Orthic Shorthand – Write as fast as you type

One of the things I like about Gregg is that similar sounds p/b f/v t/d have similar shapes so when reading, if it’s ambiguously or wrongly written, by pronouncing what’s there, I can figure out which one was meant. Also, since Gregg is phonetic, I don’t have to worry about how to spell either.

Orthic has some of that, but not to the extent of Gregg.

drewcsillagon The damaging results of mandated return to office

Would there still be as much pushback? Yes.

Open office environments are terrible for productivity, stress, health, etc. — the science is pretty well settled here.

“Cities aren’t loud; motor vehicles are”, especially busses and subways. They can be nearly deafening.

Cars comparatively are nothing.

Accepting random stuff like this is in the spirit of the protocols of the internet.

drewcsillagon Shorthand

There's this for Gregg https://www.amazon.com/GREGG-Shorthand-Manual-Simplified/dp/...

There's also handywrite (http://www.alysion.org/handy/handywrite.htm) which has the nice thing that the essence of it (not much different than gregg really) fits on an index card.
