Yes, processed meat alternatives tend to be significantly higher protein per unit mass than beans. But other metrics like protein per calorie can be useful.

I see. But now you're in a weird state where you're saying (something a bit like) "at most n^2" to mean "not at most n". Which isn't particularly precise.

It's entirely nonsensical to use O as a lower bound though. You could have two companies no growth whatsoever in value and correctly state that one has O(n) growth rate and the other has O(n^2) because a constant is both O(n) and O(n^2) (and O(n!) and O(exp(n^n)) ...). The author is trying to argue that there's some separation between two hypothetical startups' growth rates and as such an upper bound on one, say O(n), and a lower bound on the other, say Omega(n^2), is warranted. It sounds like you're not entirely an expert despite your recently-passed final. Strange concept, eh?

Yep

This is one of the myriad situations where Omega should have been be used, not O. What are they teaching in schools these days?

This seems like a new definition of entropy unrelated to existing notions of entropy relevant to language. I'm not sure I buy "entropy = 1/abstractness"...

Have you heard of pandoc?

I've never understood striking guidance either. It seems that over long enough distances everyone is a heel striker too, it's just more efficient. So I'd assume that any advice you hear is more pace-dependent than it appears.

There are more accidents in the US than in civilized countries. Per mile.

This is often user error. Many bike lights have a daytime mode that is far too bright for night. But winning the arms race is so important...

Some of the current players are already screwed. There is less water available than is desired. The government isn't supposed to come in and screw everything up they're supposed to spread the hurt around "fairly" or in some other way compatible with the national interest. This isn't some arbitrary reorganizing of water rights for political ends, there just isn't enough water in the American West for old ways to continue.

Right, naively assuming the creation of a management class is a good thing doesn't sound wise.

Most academics didn't choose the career for the management side of their responsibilities. Perhaps concentrating those responsibilities in a few managerial types would free many people to do what they really want.

British, run by some fantastic people from the University of Cambridge. Arguably there is no institution with a better reputation in this domain. I did some front end and back end work for them over a decade ago and there's definitely some good mathematics in there. Their mission is to enrich mathematical learning for all levels, but there's plenty of content designed for gifted teens.

I suggest looking outside the US for a curriculum. The nation that came up with the terms "precalculus" and "prealgebra" surely has a pessimistic view on the value of elementary mathematics. The ideas do not exist only to prop up calculus and algebra!

Warning: study is in mice and is quite specifically about schizophrenia. Your mileage may vary.
