What are interesting subfields of math?
I'm planning on buying a book for summer and learn a new topic from scratch. What are good subjects/books for an undergraduate?
(ie: a book that doesn't require too much background)
Also, ITT discuss your summer plans and ask/give recommendations.
do a fucking internship.
>>8104309
Bit late for that innit
>>8104322
is it?
Which programming language is best to learn for math fags (not necessarily majoring in CS or anything). I'm thinking Python.
Lisp
Haskell
>>8104016
Best: Maple, Matlab, C++
Useful: Lua, Python, Julia
Neato: Scheme/Racket, Haskell
If your job requires it: R, Fortran, Mathematica
Waste of time: Java, C#, Ruby, PHP, Brainfuck
Anyone ever read Feynman's lectures? would you recommend them?
>>8098914
No
read the book by dirac on qm and the one on black holes
yeah, they're fantastic if you've already learned the physics
when i'm feeling disheartened/unmotivated, i crack these open and just read them for a while, by the end I'm smiling and motivated to do physics again
>>8098926
>>8098941
ah shit, sounds like they're not much for me then. I heard feynman described as "the great explainer" and thought it might be good out-of-term reading to keep up with/ahead of my lectures. I'm an undergrad, do you know of any books which would provide good additional reading at essentially babby level?
I'm having trouble reconciling what I know about physics and the concept of free will.
1. There is no distinction between atoms in a human and atoms in the wall, air, star, anywhere else.
2. The laws of physics are deterministic (other than probabilities in QM, but the outcome of statistical interactions are still out of human control so the argument still works)
3. At t = 0, a particle is at position x. With a given velocity and forces acting upon it, at t = 1 it is GUARANTEED to be at a given position y. This occurs with every particle. So if at t = 0 our...

Prove you have no free will

>The laws of physics are deterministic
There are no laws of physics. Only approximate models which are deterministic. Even in classical mechanics, we have no way of knowing if any of the relationships are slightly random but beneath the thresholds we can measure them by.
>>8105413
Do you have the ability to go to the nail salon wearing a pink tutu and riding a tie dye skateboard? Yes, you do. Therefore, you have free will. Stop circle-jerking over the nature of determinism and do some real science.

>The puzzle that required the 200-terabyte proof, called the Boolean Pythagorean triples problem, has eluded mathematicians for decades. In the 1980s, Graham offered a prize of US$100 for anyone who could solve it. (He duly presented the check to one of the three computer scientists, Marijn Heule of the University of Texas at Austin, earlier this month.) The problem asks whether it is possible to color each positive integer either red or...

can we agree that brute forcing problems isn't that cool
>>8104675
I think it's pretty cool to be able to force a problem, it shows how much power we got.

So, will it or won't it launch on schedule?
>>8096537
Maybe it will. Maybe it wont.
The cost of waiting a couple weeks is a lot less than the cost of fucking up.
What time will it launch?
Sorry, i'm at uni
What is the /sci/entific consensus on veganism?

If you have to take supplements to make it work, it don't work.

You'd serously trust a scientific consensus? Do you believe the scientific consensus on smoking, junk food, and global warming too?
Other than writing research papers, what do you guys use LaTex for? I recall some anon's on here saying they actually put their lecture notes or example problems in LaTex. Worth it or autistic? Any other tips for using LaTex to make math life easier?
I use it for making notes on Anki a lot. Being able to make flash cards for certain concepts and equations is neat to have in addition to reinforcing with problem sets. It's also great for making your own custom notes. Say you have several textbooks that you want to learn from, you simply take what's best out of all of them and transcribe into a LaTeX document, equations and all. It's like writing your own textbook
>>8099338
Revision notes - it really helps to keep things organised around exam time.
>>8099338
If you are going to be writing papers in LaTeX, getting practice by writing your notes in LaTeX is good anyway. You will eventually be able to type in TeX about as fast as you type normally. I have bad handwriting, so I like typing my notes, and when I took classes like model theory or commutative algebra, something which uses a lot of different alphabets (fracturs, script, greek, etc.), it became really helpful to be able to type things using the right symbols straight away.
Then you will also have a bank of...

Is he right, /sci/?
Is this topic actually not interesting?
Or you actually don't know about this matter?
If we try to terraform by nuking Mars for example then I doubt it
First, we don't have the technology to make another planet habitable, secondly, if/when we do develop this technology it will likely require the complete deconstruction of the planet's surface which is something we can't really do with an already-inhabited planet.
Does the guy who made this have a point?

>spends a fair amount of time walking upright
is not the same thing as
>is fully adapted to walking upright
if you watch bonobos walk, their gait is awkward as fuck. it's nowhere near as smooth as an animal fully adapted to upright walking
you can teach dogs or cats to spend lots of time upright too. that doesn't mean they're bipedal

Evolution is yet to be proven to be disproven by anyone

Evolution is not a falsifiable claim.
what was the biggest scientific mistake that stopped/drew science progress backwards for centuries ?
i'm asking for a scientific mistake, no religious debate allowed
>>8088198
Probably the aether. At the time it was pretty reasonable, but still wrong.

Well I mean dark matter is pretty similar isn't it?

Gambling noob, heres my question
So lets say youre at a casino, putting money on a coinflip which is exactly 50/50. What im thinking is that there should be almost no possible way to loose money provided that you can bet as much money as you would like as many times as you like and always recieve either the exact amout back if you win or loose the exact amount if you loose. So what Im thinking is that if you bet 5$ and loose, youre down 5. So you bet another 5 for the chance of making the money back. Now lets say you loosr again and youre down 10. You bet 10$ for a chance...

It's possible, but it's also possible you could lose for eternity.

https://en.wikipedia.org/wiki/Martingale_(betting_system)
This is one of the simplest betting systems that a gambler discovers. It does not work and leads to tears and ruin. It doesn't take much analysis to realize that this strategy only works if you have infinite money and there is no bet limit.
Casinos exist because they make money. You can only beat the system in games that you have some control over, such as counting cards in blackjack.
hey /sci/ I'm trying to see if I could make a proof of concept exo skeleton inspired by Fallout 4's power armor frame, should I use hydraulic cylinders or pneumatic air muscles?
>>8101858
hydraulics would be much heavier, right?
I'd go with pneumatic
then again, I'm not an engineer
>>8101872
That's exactly what I thought, but they could take more weight overall, my main concern is the power supply

I've been considering becoming an Organ Donor but have been watching videos on the matter and am scared.
I see that they keep your body alive and it responds as if it was in pain.
Can you feel pain when donating organs?
They keep your body "alive" for a long time and the surgery alone takes hours.
>Can you feel pain when donating organs?
If you can feel pain after death you can surely feel the smug sense of self-satisfaction when donating the organ, so I say it evens out.
/n/ here, want to know this too, my organs might be useful when a truck crashes my bike on the road
Being an organ donator is allowing the doctor to murder you prematurely so they don't have to wait around for you to slowly die
