Hi everyone- I'm a junior at U. Penn doing a research project on thermal expansion in complex perovskites. I'm having trouble with a computer program that I'm using to control and obtain data from our dilatometer. The problem is that the software was made in the mid to late 80's, and it only...

I was in the bus traveling at 100km/h going to N and i saw another bus going to direction S at the same speed and the same bus and when the other bus that was heading S passed by ( it was 80~100cm between the buses ) i felt the bus shake and heard a swoosh sound ( the window was open on my...

I was watching the Elegant Universe on PBS, and the show was talking about the string theory. there was one thing that i didnt really get though. It was the relation between strings and branes. I think i heard that if you were to add energy to a string, it gets bigger, and is stretched into a...

I had an idea the other day that if I could set up a wireless connection from my laptop to my pc which is connected to the internet via cable I could work on my laptop down the road (in a pub or park depending on the weather) I guess it would involve some protocol like bluetooth has anybody done...

Last December, I noticed that the December issue of "National Geographic" magazine had a feature story (30+ pages long) on samurai. I immediately suspected that this was an advertisement/PR for Tom Cruise's latest movie "The Last Samurai," probably paid by him or his camp. What do you think?

Does existentialism have to do with idealism? I mean, in the sense that nothing exists outside of the minds' awareness of it? Sort of like Berkeley's idea? Do they have anything to do with each other?

I've been studying the rule of 72 lately, which gives the time in years that it takes for an investment to double based on the annual percentage rate of growth.I have tried to compare it's formula t=72/x (x being the number in front of the percent sign) with the exact value for the doubling time...

A good read. This gets a little more serious though. Please see what follows the mythology below. http://www.vanhunks.com/tokoloshe1.html This is the story that I was actually reviewing when I ran across the brown, hairy, one-butts with a lisp. Formally known as The Zimbabwe School...

An incredibly loose thought, which i do not care to think about any further, is expressed here... The Bible fames light alot... It characterizes light as a life giving component and a gift. Light, physically, is possibly the most fundamental component of our universe. a connection...

This has been bothering me for a long time. This thread (for those who will argue) will also go under the particle physics section too. Ok, in our world we live in, we have our basic particles (strings, quarks, gluons, electrons, whatever) these particles held together by forces make up our...

how can the God connection be developed if you don’t have one? it is not difficult. start by consciously having that as a goal. try the following prayer: God that i be with you in conscious contact, that i feel your presence in my life. then observe obstacles you have in place against feeling...

I ran across this paper some time ago. I would be interested in any comments that you may have. http://www.laboratory.ru/articl/hypo/eax060.htm

Members of Bush's Cabinet, all from big oil and energy and mining? You bet. http://news.bbc.co.uk/1/low/world/americas/1138009.stm http://www.opensecrets.org/bush/cabinet.asp

In the Physics forum, jby started a LQG thread which at one point included some discussion of Connections. It might be helpful to have a thread focused on the connection which is taking over the central role from the metric for some purposes. GR used to be the study of the metric on a smooth...

My first post, about rotation groups.. A result about rotation groups. To me this seems clear, simple and very intuitive, but in all the papers and books I've read on the subject I have never seen it presented. Maybe some of you have seen it, or maybe it is new. It is very simple to state...

can u share files and printers on a router as well as a internet connection?

What hardware do i need to buy ?

Here's the idea. We can help each other study for our qualifier exams by posting qualifer-type questions along with the solutions in this thread. I think this thread will also help those studying for the physics GRE... or even those just wanting to get good at solving exam-type physics...
