>> One annoying thing about both the Collatz and Goldbach conjectures is that if they are unprovable, it's also impossible to prove they're unprovable (unless math is inconsistent). This has been proved!

That’s the most fun thing I’ve read all day!

It's both. The axioms are invented, the corpus of theorems is discovered. As once the axioms are chosen the provable theorems are already fixed.

But the axioms are a choice, and we can pick different ones. The common choice of axioms is utilitarian, they lead to interesting math that helps us describe the universe.

I would agree the axioms are chosen, but what’s the connection between choosing something and inventing it?

Choosing to study molecular biology doesn’t mean cells are a human invention.

I went to an in-person Q&A featuring a Fields medalist. The audience was a collection of undergraduate and high school math students, with a few professors in attendance.

One of the young students asked exactly this question to which everyone in the audience collectively groaned. The Fields medalist gave a short answer, something along the lines of "I don't know a single mathematician that thinks it's invented."

He was being polite, but you could tell he didn't think there was anything else interesting to say.

Have you read the letter? "Because you are attacking us" is on the list, yes. But then it goes on to specifically call out our freedoms. Pretty much using those words, even.

> How could any person with even a high school education ever repeat that nonsense, much less accept it as true.

I'd guess that most high schoolers can read the letter.

Thanks for mentioning this. He states explicitly he hates America for giving individuals personal freedom and not abiding by Sharia Law.

This is a really bad article. There is a nugget of truth, but it's never properly articulated because the author himself doesn't actually understand the distinction.

If you've already decided you want to build a unicorn and are willing to make take that <1% chance of success, YC will help you. If you want a lifestyle business, you could probably skip YC (though you probably wouldn't get accepted even if you applied with that idea anyways).

For clarity it should be:

MOTIVATION = EXPECTANCY x VALUE / (IMPULSIVENESS x DELAY)

It's surprising that Code, by Charles Petzold, didn't make the top 50. That's one of the most approachable books out there for learning how computers really work. I see a lot of mentions of Code on HN but maybe that is skewed by the links for which I read the comments.

"here's what we should do" is not advancing science.

do the thing, get the results, and if they're significant, then author a paper.

I think there is a lot of resume oriented science, these days, because publishing lots of papers looks good on your resume. i mean, we can't let actual science get in the way of our science careers, right? we gotta publish papers telling people what we're thinking about, and how to do those things.

this type of discourse is very common in physics, where the theoretical physicists propose a testable hypothesis and then the experimentalists verify or disprove it.
