Does anyone know the book "Optimization over Integers"? Is it available as a pdf somewhere?

what's the best adderall alternative that's legal without prescription? adrafinil? noopept? piracetam? come on /sci/

What was Richard Feynman's GPA as an undergrad?

Any of you guys using nootropics?

Pic related, it's a projection of a rotating 2-sphere onto a plane. Anyone know of any images of an isoclinically rotating 3-sphere projected onto a volume in this way?

One problem before going to sleep? Im stuck at this, I would like to see the opinion of others...

explain

Okay, one of you genius anons must have studied in the medical fields or know a fair amount about the inner workings of the human body... Lately I've had trouble pissing alongside feeling bloated, and when I poop it smells like straight up cow manure Can anybody offer insight as to what may be wrong? >in4 OP the problem is your a faggot

Which science is harder: biology or particle physics?

What lies beyond the universe /sci/? Since it has been said that it is expanding, then the universe is expanding into what? Is the universe making new spaces as it expands?

>yfw casuals are acting like they knew who the fuck Schrödinger was before google put his cartoon up today

The other day I accidentally wrote a number theory problem that nobody I know can solve. Can you guys solve it please? Find all integers a, b such that a^2+b^2 is a square (pythagorean triple) and that (a^2+1)/(2a^2+2) is the square of a rational number (eg. 4/9, 8/18, 1/25 etc.) pic unrelated I would be so grateful if you could solve this.

What does /sci/ think about this? >http://www.youtube.com/watch?v=AzE_IHGUssY Apperently, the Egyptians couldn't have built the great pyramid using their technology. It also shows the mathematical beauty of it(pi and the golden ratio appear often), which is contradictory to our current beliefs about Egyptian mathamatics. Also, they somehow knew the meter and were able to make perfectly symmetrical faces on statues using rocks and chisels. I just want an engineers perspective of this.

Hi /sci/. I'm writing a novel which includes highly modified Sol. Sun is 14% lighter, Moon's (52% lighter) orbit is circular perpendicular to the line between Sun and Earth and Jupiter, its year is as usual 28 days. Earth orbit is circular and it's in L1 Lagrangian point of Sun-Jupiter (kept stable). I tried to make a program that predicted when the Moon is visible, but it turned out quite complicated. Are there any tools to do it easier? Any tips, at least?

p-please help /sci/ I'm struggling with a few differential equations questions and would greatly appreciate some guidance. So i'm trying to find equations in terms of Q dQ/dt=(m-n)Q , m=0.1, n=0.06, Fairly certain I ended up with the right thing Q=200e^t/25 My actual trouble was with the DE: dQ/dt=(m-n-kQ)Q , m=0.1, n=0.06, k= positive constant Any points in the right direction would be greatly appreciate. And yes, I already know this is sub-babby tier.

What can be done for it? I hear taking DHT suppressors works/slows it down.

Which scientist do you believe has the classiest glasses and has made significant scientific contributions to STEM pursuits? >pic related My nigga Planck.

if you move the point M along the AC line, then the lengths of BM and MA changes, which means that sin, cos, and tan of angle A also changes, even if the angle A is the same all time. I feel like an idiot now for not understanding what's wrong.
