Hey, I hope everyone survived the festivities of the new year. I would like to take this opportunity to thank everyone who has participated in our Group, and...
As I have just finished the graduate school application process, I will focus on this aspect of my physics experience. First a quick summary of my experience...
Hey spurny! Thanks for the very informative essay on the trials and tribulations of applying to graduate schools. And to think that this is just the beginning...
Ok... we had a few members submitting answers that are in the right ballpark for our last week's vexer. If you recall, I asked the following: One of the more...
OK, this one is DEFINITELY an easy one. So send in your answer, especially if you've been shy in playing our vexer before this. On a very hot, steamy day, a...
Periodically, we have "creatively misguided" people coming into our IRC channel claming so-and-so theory is wrong, or invalid, etc. More often than not, these...
Nobel Laureate G. 't Hooft has made an interesting proposal that QM can in fact be extended to the Planck length scale and become "deterministic". You may read...
OK, since I was the one who proposed the group project of collecting all the various evidence, I thought I should start it. The focus in this post is the speed...
Hold your horses! In an earlier posting, I reported the experimental observation reported this week at the American Astronomical Society conference regarding...
Humm... people must still be off in the holiday mood. Last time I asked the following question: On a very hot, steamy day, a non-physics major (we won't name...
OK, this vexer may appear to not have enough information. But trust me, you have all the necessary information to solve it. So give it a go! A census taker is...
Continuing the series on the Top Ten most cited paper from Phys. Rev. Lett., this month's issue of APS News list this paper at number 8 (the 9th and 10th were...
Hey, I think almost everyone is back from vacation! We had quite a few people playing our last vexer! If you recall, last time I asked the following: A census...
OK, this week's vexer may be a hit-or-miss thing. Why do we see only one side of the moon? Because the moon turns on its own axis at such a rate that as it...
I supposed I didn't get EXPLICIT enough in telling you what is required to answer this vexer. "Why do we see only one side of the moon? Because the moon turns...

hi I got a question : how to determine the temperature of incandescence of a lamp, without using a pyrometer ? thanks in advance bye ...
Since Goldstein's "Classical Mechanics" is such a popular, almost standard text for intro graduate level classical mechanics, I thought I should point out a...
OK, switching gear a bit into frivolity, here's something from the mathematics world that might be fun to look at. Unless you've been living under a rock the...
Admittedly, last week's vexer wasn't easy. Even the "accepted" explanation is still being refined even today. And there is nothing wrong with looking up the...
OK, this is one of those questions where, if you have the patience and the skill, you could test this out for yourself. Blow up two identical balloons, one...
More frivolous stuff, this time from physics. The author of this paper, which will appear in the Feb. 2003 issue of the American Journal of Physics, have made...
Remember many weeks ago that one of our vexers asked the question on what would happen if you throwing a weight off a boat that's floating on water? It appears...
The last vexer was indeed a stumper! No one got it right! If you recall, last time I asked the following: Blow up two identical balloons, one more than the...
After a difficult one last week, this one should be a walk-in-the-park! A high-school level question that everyone should be able to answer! In fact, I asked...
A quick glance at one of our Polls shows that the prodominant academic group of our members are undergraduate students - in both physics and non-physics...
