How's everyone doing on any resolutions made for the New Year? Mine: Obey the posted speed limit. Progress: Good progress on side streets. Caught self doing 70-mph in a 60-mph zone on the freeway once, but generally staying within 2 or 3 mph of posted limit.

Hey, Physics World has http://images.iop.org/dl/physicsweb/PWDec07quiz.pdf" from 2007. There's a £50 prize for someone who gets most of the answer. Wouldn't it be nice if a PF member wins this? :) Zz.

Hi, at the moment I am using the set book (Physics for scientists and engineers, Tipler) for my core physics modules at uni. However I want something which has roughly the same stuff in it but which will present it in a slightly different way. A good analogy is my use of maths books, I use both...

I won't be around tomorrow night to enjoy the annual near-beer and Nyquil New Year's Eve countdown (I actually have real life friends to spend the evening with this year :biggrin:), so I thought I'd wish everyone a Happy New Year a bit early, and at least get the party started. Hopefully by...

I'm about to begin a bachelor of science with a physics major. I've already found some books on electrodynamics and relativity and such, but I can't find the motivation nor resources to intepret some of the more abstract mathematics, especially to do with linear algebra, tensor analysis and...

I just read that the Gregorian calendar is off by 26 seconds a year from the solar calendar. That adds up to about 43 minutes ever 100 hundred years. Does this mean that if it starts to get dark at 5:30 pm on the East coast on December 1st, that it got darker 43 minutes earlier or later 100...

Hi, second term is coming up, woot. I have e&m next semester and I heard that griffiths is one of the best texts around on numberable occasions, my university has it but it's not for my class but a senior class instead. I don't see why I need to use a certain textbook, I didn't for calc or...

hey, I am curious to hear how everyones grades changed as they progressed through higher education? In high school I had around a 40% average, then after 5 years I re-took all my high school math and science then applied at university to get my honors in physics, my first year I had a 65%...

I've always heard that 2007 was the year that may falsify string theory at a large collider in CERN or somewhere. 2007 is nearly over. I haven't heard anything about it. What has happened over there?

2007 Paper of the Year (A+ for "leadership ability") in junior high school they started telling us about "leadership ability" which apparently was exemplified by some guy who was good at sports, didn't bug the teachers, and was perhaps a bit cleaner than usual. It certainly wasn't clear to me...

Suppose i have two clocks on Earth showing 12:00 hours. After, one of the clocks is put in a gps satellite for a year. After one year that clock returns to earth. Due to relativistic effect what time that clock shows? Less than 12:00? If so why?

This is a very long story; please bare with me! I am a first year undergrad student nearing the end of the year. I am from South Africa (at the University of Cape Town). The way it is here, is that for your undergrad degree, it is standard to take two or one majors. In first year you take 4...

I am in a little dilemma. I have taken interest in a 2 year EET program at my local community college but am unsure if it is marketable. From my research, an AAS in Electronics Engineering Technology would qualify you for a technician's job. Are technician's in high demand these days? For...
