Say I have two lists, List1 and List2 containing elements such as words. Some words are common two both List1 and List2. I want to create a distance metric that tells me how far apart the two lists are based on a similarity "score". The similarity score and distance metric are as follows...

Hi all, the title I think says it all! Is there a list "out there" of PhD physics departments with the lowest application fees?

Back when Einsteins theory was very new I think there was a small list of people who understood relativity. For example Freeman Dyson wasn't on it, so when he wrote a book about Einstein the publishers were skeptical and it ended up with him meeting Einstein and all went well.. and there are...

I've been reading some papers about electron double slit experiments, including the one by Jonsson which seems to be the most detailed and well written so far, but I've only been able to find about five papers total. Jonsson was one, then a 1989 single-electron double slit experiment, and a few...

Hi, Can someone suggest good sites to find a fairly comprehensive list of upcoming workshops (meaning for the rest of 2010) in all areas of theoretical particle physics or mathematical physics (especially quantum gravity related stuff but I am interested in other fields as well)? I might be...

Not so much a homework problem as a curiosity on my part. I chose to give a presentation recently on undefined numbers. With that, indeterminate's unsurprisingly found their way into my presentation. After reading up on the list of indeterminate forms, I stumbled upon the form 0^\infty and...

After using NSolve, I have a list of numbers but I only want mathematica to print the ones which are real numbers between 0 and 1 (inclusive). How do I do that? Thanks!

I just took my final for Data Structures and there was a question on it dealing with linked lists. A part of the question really threw me off. It looked something like this: public class Node { int contents; Node next; } public class LinkedList { Node head, tail...

This may be somewhat of an odd request, but I need a list of all physics formulas in the broad subject of physics (probably just into to physics level), preferably in plaintext. Anyone know where I can get this? I'm not looking to study it, so I'm not looking for a list of nicely categorized...

Is there such a list somewhere in the www? My motives are pure... :!)

Does anyone know where I can find a list of Christoffel Symbols for various metrics? Metrics of general forms, as well as famous ones like Schwarzschild and Robertson-Walker? Yes, I can calculate them all if I really need to, but it's pretty tedious.

Is it safe to assume that the absolute value of sin x is greater than zero for all positive integer values of x? I have no real experience in number theory, and I don't know if you can say that there are no irrational numbers in an infinite list of integers.

Hi there! Just asking for a website with a detailed list of winter/summer schools, workshops and so on for the full present year, related with quantum gravity. Thank you very much in advance.

http://rjlipton.wordpress.com/2009/12/26/mathematical-embarrassments/: i didn't think the invariant subspace problem would be an embarrassment. i guess it's not all that hard for finite dimensions. only one person mentioned goldbach's conjecture, & nobody said anything about perfect numbers...

If I have a .TXT file with comma-separated e-mail addresses, is there some way that I can quickly send an e-mail out with all of them in the BCC field? For example, could this be done from the command line in Linux (Ubuntu 9.04)? Is there some way that I could have the contents of another .TXT...

The most recent version of the theorem, as stated by Nikonorov in 2004 Let G a connected compact semisimple Lie group, which acts almost effectively on a seven-dimensional simply-connected homogeneous space M^7=G/H. If (G/H,\rho) is a homogeneous Einstein manifold, then it is either a symmetric...

Hi everyone, I have a folder of Vietnamese songs (files). The file names are in Vietnamese. I used a VB6 program to create a list of file names and output them to MS-word. The program won't understand the Vietnamese characters, suc as ^, ., ~..., so it was represented by question marks...

How extensive is your "To Do" list? I have more items on my list than I could possibly complete in my lifetime, but it's mostly for keeping busy. Prioritised by the more important things to get done, I think a decade or two will see fulfilment. So I was curious about to what extent everyone...

I couldn't find list of functions or operators. My naive approch was to list the elements of Symbol as Symbol seems to be the Head of all functions--but this didn't work. Is there a way for Mathematica to generate this?

I'm sure this has been asked numerous times so I apologize ahead of time. I have no physics background but have been increasing interested and have read a few books in the recent months and my curiosity has only grown. So far I have read the following. In Search of Schrodinger's Cat - John...

Hey guys, I'm trying to implement a linked list in C, with each node carrying fields from a text file. The problem is that whatever was the last line read from the text file gets placed into every single node. Even more strange is that when I add an additional node outside of the while loop it...

So my algorithm compares a node that needs to be inserted with the current linked list set. it goes from first (which contains the lowest integer) and moves forward until it hits null or when the key trying to be inserted is no longer greater than the nodes being compared to. My input of 23...

I have a list L={a_{1}, ..., a_{n}}. I would like to find the mean of L_{i} := {a_{1}, ... , a_{i}} for each 1<i<n, and then plot the means. How do to do that in a smart way?

Hi, I've just ploted a graph in Maple from a list thanks to the function pointplot(...,style=LINE). The graph(cf attachment) "looks like" a continuous function. So my question is the following: Is it possible to define a function from a list in Maple (provided that the plot of this list...

I'm currently a freshman at UIUC and a physics major. I've asked for a lot of advice on these forums and elsewhere and I think I may want to consider a double degree in some sort of engineering and physics. I have all my general education requirements done (thanks to a lot of AP credits) so all...
