The idea of a point cloud representation is similar to what I had in mind. The f(x,y,z) spans many magnitudes in value. I'm only interested in those points that have a larger value of f(x,y,z). As such, perhaps I could have a lower threshold, below which a point will not even be generated...

First of all, let me apologize if this is the wrong section to post to. I am in need of ideas on how to visualize a large dataset. I have a dataset (~4GB) of x,y,z,f(x,y,z) values. To best be able to draw conclusions from my data, it must be plotted in such a way that at each x,y,z there is...

We have: mR^2\ddot{\theta}=mgRSin(\theta) Which can be rewritten: mR^2\frac{d\dot{\theta}}{dt}=mgRSin(\theta) We make the substitution: \omega=\dot{\theta} Such that: mR^2\frac{d\omega}{dt}=mgRSin(\theta) By chain rule...

Homework Statement Consider a smooth hemisphere of radius a placed in the Earth's magnetic field. Place a small point mass on the top of the sphere and provide an initial small displacement as to allow the mass to slide down the sphere. Calculate the point where it falls off the sphere...

Homework Statement Prove the following: (\vec{r}\times\nabla)\cdot(\vec{r}\times\nabla)=r^2\nabla^2-r^2 \frac{\partial^2}{\partial r^2}-2r\frac{\partial}{\partial r} Homework Equations (\hat{e_i}\times\hat{e_j})=\epsilon_{ijk} (\hat{e_i}\cdot\hat{e_j})=\delta_{ij} The Attempt at a...

Homework Statement Given a rocket that is accelerating upward until escape velocity, find m_gas/m_rocket. Should be near 300, I'm getting 6.5.Homework Equations The Attempt at a Solution Here's a pdf in google docs...

Thank you very much! I will make some revisions. Come to think of it, revisions might not help this. Thanks for your time!

I'm not wanting to get into an awesome school. I just want someone to look over this to make sure that I don't sound too bad. Here goes nothing... Any feedback would be appreciated! (I know you all are probably tired of reading these.) It seems to me that life is a constant uphill battle...

Good luck!

What forces are going to be acting on the passengers? How does the coefficient of friction play into finding the frictional force? These questions should get you started on getting an answer.

I got accepted to a Physics REU at Boston College at the end of my sophomore year. I come from a small liberal arts college in Kentucky. It doesn't cost anything to apply, so why not?

Thank you, I was able to get to the solution!

Homework Statement Tan[60 degrees]=Sin[theta]/(1/3+Cos[theta]) Homework Equations Trig identities? The Attempt at a Solution Tan[60 degrees]=Sin[theta]/(1/3+Cos[theta]) (1/3+Cos[theta])Tan[60 degrees]=Sin[theta] 1/3 Tan[60 degrees]=Sin[theta]-Tan[60 degrees]*Sin[theta] Now I'm...

The reason I want to to switch fields is because I don't think that I will enjoy doing research in physics. All of my life I've loved computers, when I first entered college I was wanting to go for computer science/electrical engineering but it would have required me transferring to a different...

I'm soon to be finishing up my bachelors in physics and I'm wondering if it's possible to go into a PhD program in computer science? I haven't taken any courses at my university in the CS department, but I've spent most of my life learning and fooling around with computers (probably more than...
