I don't see how that makes that assumption...could you elaborate?

I would think that quantum random number generators (that are based off truly random quantum processes) are random (http://photonics.anu.edu.au/qoptics/Research/qrng.php))

As for the other part of your question, perhaps the mind's processes are quantum ones and not classical. Penrose believes this, I think.

Textbook help. I know there's a sticky, but that lists a bunch of stuff and I'm not just looking for a list but for the awesome subjective opinions of you guys on which is the BEST introductory/first-year-undergrad textbook on
-Math (Analysis, Algebra, nothing too advanced)
-Physics (Mechanics, E&M, Thermal, Quantum, etc)

Never had too rigorous a highschool education so even some sort of bridging text (like 'A Concise Intro to Pure Mathematics', etc.) would be great as long as it's very rigorous and among the 'best'. But nothing beyond first-year undergrad level, pls

Would appreciate a lot, just looking for what you guys think are the best books, from experience, I'm sure if you really loved a book you wouldn't mind sharing the name. Something like Spivak for Calculus (already on my list) Thanks

1st year uni. Could you elaborate on how you can solve for n using the gamma function?

pic is random

Hi guys, I was working on some random inequalities (not hw) and wondered if it was possible to solve a factorial-involving inequality, for example the smallest n for which 10^n<n!, analytically...

Any ideas? I'm fairly certain there would be at least one method that does not involve extremely advanced math.

How old are you? they're obviously small changes in the gradients which translates to a big area difference. The pieces don't "perfectly fit" even though they appear to.

Haven't you come across this in primary school? : https://upload.wikimedia.org/wikipedia/commons/thumb/5/5e/Missing_square_puzzle.svg/300px-Missing_square_puzzle.svg.png

Watch when the piece from the top right is descending down the left, the little triangular bit at the end magically grows on its way down even though it is not as big as the little triangular tip of the original piece

I think he means which is the largest cardinality for infinity. Which doesn't really make sense, I know

>is this the largest?

No, because you can add 1 to that and it will be even larger.

Stick to biology.

I understand that you are still in high school. But you should be
1) learning everything that you really are supposed to have learnt by your age. After the IB I had a decent knowledge of complex numbers beyond de moivre, and also infinite series, series approximations more complicated D.E.s, etc. These are all offered as higher level modules in high school math courses...you should be exhausting these.

2) Learn stuff beyond your age (once you're done with that). Most geniuses don't follow the same learning curve as the rest of us. Take ANY example, Gauss, Ramanujan, Terry Tao, even Feynman. That's the point of a genius.

Don't boast of your ignorance. Only just learnt about Matrices and Complex Numbers? Clearly your immediate plan of action should be to familiarize yourself with some of the core fundamental topics (including complex analysis, matrices--leading up to Linear Algebra, etc.). I don't think you need much more than a high school textbook at this stage.

okay, thanks.

damn.

really? example?

ff(x)=f(f(x))

f(x)=x^2
ff(x)=(x^2)^2

hypothetical scenarios dont necessarily have to be probable or even plausible. you're confusing the scientific usage of the word with the colloquial usage. when used in the phrase 'hypothetical scenario' it is used in the colloquial sense.

Spivak Calculus 4th edition?

No wonder, your mother seemed pretty decent looking tome
