Hello everyone, I've been watching the Khan Academy physics lectures and although they're nice (does anyone know a better one?) I'd like to get much deeper into the details of everything. So please if any of you knows a book, preferably available for free, which is really detailed and of an...

If this is true where is the core of that star, either a neutron star or a black hole should exist near by, right?

I've tackled a lot so far! I've created methods to delete, get the weight, and sort the tree by name. My goal is to have my switch criteria change how the tree is sorted, either by weight or by name. I haven't figured out how to implement it within my switchCriteria() method, so I've been...

I am having a hard time implementing comparing a given String name with the names of the Dog objects in my binary Search Tree. The problem comes from my containsRecursive() method. I need to use a String name to find if the name is already in my Binary Search Tree.Here's what I've tried...

The thread https://www.physicsforums.com/threads/how-close-is-earth-to-the-closest-black-hole.939912/ reached a conclusion that there is a 65% confidence level that there is one black hole within 50 ly of Earth. The link http://www.solstation.com/stars/s20ly.htm says there are 25 stars bigger...

For the first time in my lime I am not able to find home page for well-known and respected western periodical. I am looking for the paper titled «Définition covariante des équilibres thermodynamiques» by J. M. Souriau published in Supp. Nuovo Cimento, 1, I , 4 (1966) pp. 203-216 (given the fact...

Hello all! I'm preparing to transition out of the military, and will have about 4 courses left on my BS when I do. I think it's about time to start looking at grad schools! (YAY!) However, as I look, the possibilities seem almost overwhelming! My question, therefore, is not about how to...

Why does Google limit its searches with 32 terms? I think other search engines seems to not limit but adding more terms for some reasons such as filtering does not work, for example in Yahoo. Thank you.

I am on a quest for the most perfect spreadsheet designed to assist with choosing or applying to phd programs. If anyone is in possession of such an artifact, I implore you to bestow it upon me so I may bathe in the light of the knowledge garnered by those who came before. If your wondrous...

Hi, a very basic question: what is a good intuitive way to understand the importance of a reference prior? In the context of a signal search. Bellow, I also try to give the way I understand the approach in a Bayesian analysis (roughly): 1. You have your likelihood model L = p(x_{obs} | \lambda...

I am very interested in Astrobiology and just came across this 7-year old abstract by Seth Shostak (of SETI): http://www.sciencedirect.com/science/article/pii/S0094576510002195 There is a lot of emphasis on searching for biological life outside of our solar system, especially with the...

Hello all! I recently had a few major changes in my thinking about what I want to do with my life. For awhile, I thought I wanted to pursue my PhD in physics, so I signed up for the GRE and with it I signed up for the GRE Search tool, which I guess is a tool schools can use to find potential...

Say I want to do molecular dynamics simulations on a crystal of a specific substance. I get on Scopus and search for it, say going back a couple of years with the results, and then I also check the references in these papers. How can I be kind of sure that this background research is adequate?

What happens, if instead of having any pointer pointing to a node's parent, we had pointer pointing to the node's successor? We know, that Searching would remain the same. But in my opinion Insertion and Deletion would change. This would happen, because in insertion, we would be needed to find...

My instructor asked us to create a binary search tree in python that supports variables. i.e. the tree will have variables inside, and the user can get the values for those variables by looking for the name of that variable. I don't really know how to implement this. What I have so far: class...
