Or perhaps I don't have such an option readily available.

Perhaps this is a little too speculative to be in accordance with PF rules... I guess I should probably delete it.

Europa, one of Jupiter's large moons, is predicted to have a salty ocean beneath its icy surface. This ocean is expected to have more liquid water than the oceans of Earth have. Virtually every place on Earth that we find liquid water we find at least microbial life. Based on this it seems...

Also, the edge contains the covariance. Anything else? Again, thanks.

Nevermind. I think I found it. A pose graph is a graph data structure where each node is a frame with a specific origin and each directed edge is the transformation (translation and rotation) from one node (frame) to another. Is this right? Or wrong? Or is there something anyone thinks should be...

I've been looking for a definition for a while now. A google search turns up plenty of research papers using them but I haven't found a definition yet. Can anyone explain it to me? Thanks for your time!

I've recently been learning about how to tell if a matrix is positive definite and how to create a positive definite matrix, but I haven't been given a reason why they're useful yet. I'm sure there are plenty of reasons, I just haven't seen them yet. In what ways do the properties of a positive...

Not a classic or anything. I'm an undergraduate and I'm working with two of the authors. The Three-Dimensional Structure of Cassiopeia I forget am I allowed to just post a link here? Remove it please if not: http://arxiv.org/pdf/1011.3858v1 Edit: Also, it's not a major part of the paper. It...

I'm reading a research paper and they bring up the term "natal kick". And google didn't turn up a great explanation immediately so I thought I'd check here. Can anyone help me? Thanks.

Right. It's a scalar multiple of the entire function. Got it. Thanks!

Homework Statement Is the following a vector space: The set of all periodic functions of period 1? ( i.e. f(x+1)=f(x) ) Homework Equations If v1 and v2 are in V then v1 + v2 is in V If v1 is in V then c*v1 is in V where c is a scalar The Attempt at a Solution I'm thinking no...

Fantastic! Thanks! I knew there had to be something like this, but wasn't finding it.

Right now I'm running this with a brute force program which takes points on an ellipsoid and checks the distance to the point, slightly readjusts, and keeps moving toward the minimum, but it takes far to long for the mass amount of points I want to run through the program. Is there an equation I...

Making fun of the fact that I mistakenly added a t to the end of a word when it shouldn't have been there was a bit uncalled for. Physics forums seems to be lacking a little in people who are willing to answer questions without telling the people who asked them that they don't know how to do...

I'm sorry, I didn't meant to put it in cycle notation. I just meant to put it into set notation. Even just as a set does it still make sense? If so could you explain why?
