For any mathbros out there, what are some interesting properties of Pythagorean triples? I'm looking for some unique results for a proof I'm working on. Also, number theory thread.

if you take a triangle that has sides the lengths of the numbers in any given pythagorean triple, then that triangle is a right triangle.

Did I blow your mind yet.

I was looking for results more along the line of primative Pythagorean triples...

I've been using Mathematica for years, and I've learned to program there in the hard way: trial and error.
I've tried the Leonid Shifrin book, but it's outdated (some examples with "===" are no longer valid, for example.)
Anyone suggest a good source to learn how to program in Mathematica?

I also started with Mathematica.

But I don't see why you'd ever have to do more than writing scripts in that language, and they are slow.
It's good for symbolic computation, e.g. symbolic series expansions, and generally stuff which you'd have to represent in an ugly form in another language.

But if you want to learn to program, learn to program. Programming paradigms etc.

If you need to stick to it, I assume the Mathematica Stackexchange page knows more.

Would really appreciate a starting point for learning Mathematica.

If you'll look closely, you can see some kind of differential equation on the truck.

What does it mean? Often the random math/science tidbits dropped into the simpsons actually mean something

Looks Navier - Stokesy but I don't recognize that notation, maybe an engineer's notation?

Probably related to fluid mechanics, hence the joke
>>
>>7934701
I don't think it's Navier-Stokes, RT is a common product in thermo and stat mech. So perhaps something from there.
>>
>>7934714
>thermo

Yeah the first part looks like a diffusion equation. Maybe something to do with solutions/mixtures

you'll be glad you did it, it's one less math course to worry about and it's 2 month long instead of 4.

That's the problem, though. From what I've heard, calc 2 is one of the hardest math classes. Taking the whole thing over 2 months is just going to make it even harder.

what in the actual fuck?

I thought 2 months were the standard?

Hey /sci/ could a couple of you guys explain something to me? What sense does it make to say that alien life doesn't exist if we assume the universe is infinite?

In other models where the universe is finite in size I can understand there being no aliens, but doesn't there being an infinite universe mean there's a infinitely high chance of alien life?

Even if there's no proof of alien life, isn't life arising on earth and assuming it is just one small speck in the universe enough to warrant the belief in alien life?

You're right, it doesn't make sense to say alien life can't exist.
>>
>>7934618
It's the same problem as with the sum of all natural numbers.
If you calculate the chance of there being alien life in an infinite universe, you count 1 + 2 + 3 + 4 + ... and end up with -1/12, so the chance of there being life in the universe is actually negative.

I don't know what course that is, but just use that MIT lrn2lrn page it's help generations of freshman /sci/entists and it will help you too.

its really good. it actaully made me think of learning in a whole different way. it doesnt just say things that are normally said about learning. it also gives scientific facts about it. following this methods, i saw noticible changes in my marks and in my understanding.

don't post if you haven't watched the video through.

I want to get some opinions on it because I want to write a C program using this.

I imagine it could provide me an infinitely repeating matrix which, no matter how big the number, I can navigate through with the rules given. (±7 and ±2, ±5 and ±4, multiply, divide, mod 9 and so forth...)

But I'm not sure if it could be a 1D array or needs to be a 2D array and where the rules would need to apply (pointers or array).

this is not properly phrased but I hope you get the idea...

Not watching the video, you're an idiot OP. There is no "math" here to write a program with, just the ravings of a mathematically illiterate schizophrenic.

It's almost like you only want to hear things that affirm your delusions and will not listen to reason.
