The sun is made of fire. According to Google, it is 1.989 kilograms long and burns at a temperature of 5,778° Kelvin. Let's assume that there is a second sun made of ice. It is also 1.989 kilograms long, but burns a temperature of -5,778° Kelvin. What would happen if the two suns collided?

Hi, /sci/ I'm exploring the possibility of studying through open-source channels, namely MIT's OpenCourseWare (ocw.mit.edu/), and was wondering if it's viable. Is it possible to write exams at a uni, or could I be recognised some other way? I was planning on studying macroeconomic theory, and later on specialising in the austrian school of economics - though that may change during the course of my studies. Any advice would be super plox

Have average humans evolved to require and work for leaders (which may or may not be psychopaths)?

Interesting problem time /sci/: It is well known that in two dimensions it takes at least three circles (or 1-spheres) to arrive at a single solution/intersection. Let us call the number of n-spheres to arrive at a single solution #, where n is the dimensionality of the field minus 1. Thus for R^2, # = 3 Easy mode: For R^3, what is #? Hard mode: What is the relation f(#(n-1))|R^n? Meaning is there a function that dictates # based only on the dimensionality of the field? Godlike: Does this function apply to all other rational number fields? Please show all work. Good Luck.

Hey, /sci/. Why do we still teach arithmetic in schools? We have calculators, so isn't it a waste of time to spend years on arithmetic? Why don't we just start right away with algebra? That way, students can excel at math much faster than they do today, and the clever students will catch on and figure out what all of the operations mean in no time. It just seems trivial.

I am intending to do a reading course with someone I want to work with (math), and would like you to share your experiences with reading courses so that I show the guy that I know the fuck I am doing. Like, what did you do? What exactly does it mean to "discuss" what you read? ... pic unrelated

Completing a math course to get into college, this question is stumping me. Anyone willing to help solve it and explain it to me? Matt and his wife have 20 good friends, twelve of them are male and eight of them are female. They decide to have a diner party but can invite only eight guests. They decide to invite their gues ts by drawing their names from a hat. What is the probability that a) There will be an equal number of ma les and females at the dinner party? b) Mandie will be among those invited? c) There will be only one female guest? d) They will have only male guests? e) There will be at least one female guest?

I always heard about it in games like Antichamber and Portal 2. What is non-euclidian geometry?

why has science been so resistant to the idea that their are differences in behavior and intelligence between races? even james d. watson got fired for saying that the evidence shows that africans have lower iqs than europeans aren't scientists supposed to be neutral?

How do you make these numbers become the number 13: [20, 4, 12, 9, 2, 19, 7, 2, 5, 18] question to previous OP of this thread: where did you got this problem from / were you doing some recruiting / something else?

How is this explained scientifically? No motive or /pol/-influenced post, just curious. And I regularly fap to black chicks, by the way. (Somehow I feel this kind of disclaimer is necessary...)

So I have to write a small review paper on some studies concerning training effects, while comparing elites and amateurs. These have some methodological problems and the main criticism is that the training effects/different scores are to be attributed to genetic differences. While the studies as a whole are inconclusive, I'd like to make the argument, that much like in sports, there is an individual genetic potential AND training effects within that range. The question is how that would look like in the data. I believe the variance would be bigger in the amateur groups. Would I be right in that assumption? Does anyone know of studies in sports medicine or something that make this observation? Any other way to prove it?
