Hey all! I finally decided to code a puzzle kind-of game I came up with a few weeks ago and I would love it if you tried it. Let me know what you think ;) (It's hosted in my github page):

Usually, in homework problems, I come across something like, "Let F be the set of all functions f:\mathbf{N}\rightarrow\{0,1\} that are eventually zero."
But I don't really understand what is meant by that. Is it right to think about it as the set of binary numbers? If I take each f to be a...
Hello, I am trying to simulate the gammas from certain radioactive decays but I am really puzzle as to how to approach this. The site I'm using as a reference lists the intensities of the different gammas corresponding to an specific decay.
The thing that confuses me is that, for example...
Hello, I recently run into a problem. Let's say I have the point (a,b) and (-a,-b). The, I know that θ_1 = atan(b/a) and θ_2 = atan((-b)/(-a)) = θ_1.
But, what if I want to go back to Cartesian coordinates? If I assume r = 1,
a = cos(θ_1) and b = sin(θ_1) while
-a = cos(θ_2) and b =...
Hello, I am reading this article in wikipedia http://en.wikipedia.org/wiki/Attenuation_length about attenuation lengths and there is something I'm hoping someone here can explain to me.
Lets say I have one small solid sphere and one big hollow sphere. And let's say I put the small sphere...
Makes sense. Thank you.
One last thing. For the gamma rays, do the intensities represent the probability of getting that gamma ray energy? They appear to be very low since U-238 does not decay to the ground state of Th-234 ~21% of the time. I would think that Th-234 needs to be in its ground...
Hello, I need some help understanding this.
http://atom.kaeri.re.kr/cgi-bin/decay?U-238%20A
it says that 79% of the time U-238 goes to the ground state of Th-234 emitting a 4.198 MeV alpha ray. But the difference between the ground state of U-238 and Th-234 is more than 4.198 MeV. What...
