Homework Statement I'm trying to create a program which models fluids using the finite difference methodHomework Equations This is what I'm looking for:)The Attempt at a Solution I'm hoping someone can point me in the right direction. I guess at first I'll just simulate incompressible fluids...

That makes sense. Thanks!

Hi, Could someone briefly explain Cabibbo suppression to me? I can't seem to find any info on it. Is it like OZI supression where things that decay through 3 gluons are suppressed? I found it in the paper "Search for CP Violation in Charged D Meson Decays" accessible here...

Thanks everyone!

Hi, I thought pions were assigned parity of -1, but how then can the Pi0 decay into two photons with parity -1?? What am I missing? Thanks, Joe

ok, so T=T0/(sqrt(1-2Gm/Rc^2)) is an approximation for weak gravitational fields, but for massive objects it is necessary to use the equation that Pete mentioned. How would I find g00? Can this be determined directly from the potential? Thanks for your help, Joe

Hello, I have a question about general relativity and time dilation. I found an expression for the time dilation around a sphere of radius R and mass m. T=T0/(sqrt(1-2Gm/Rc^2)) http://hyperphysics.phy-astr.gsu.edu/hbase/relativ/gratim.html Is there a way to calculate the time dilation for...

Hello, I just made a program that puts numbers into a two dimensional array, and then saves them in a text file that looks something like this: 4 4 4 4 4 4 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 4 4 4 4 4 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 7 4 4 4 4 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 7 7 4 4 4 5 5 5 5 5...

NeutronStar, The problem is that we don't have a normal textbook (if we did, I wouldn't have posted here). The book that we use(which cost only $10, so I'm not complaining) contains primarily theoretical problems that don't help much for tests (and I've spent a lot of time on those also).

I am in the process of studying for my math finals, and I was wondering if anyone could help me find some math problems that I could work on to prepare. Thanks! Joe These are the topics: 1 Vectors a. Dot Product a•b=|a||b|cos(θ) i. Angles between vectors ii. Projections...

Points are measured in 4 dimensions sometimes, three spatial and the time dimension...so it would have to strike in the same place at the same time. Otherwise it could be argued that since the Earth is moving through space, spinning, etc, that it moved and no longer struck it in the same "place".
