As usual, work gets in the way (I'm organizing a workshop this coming July and so it is even more hectic than usual). So the answer to last week's vexer and a...
Hey all! (To the old & new folks) At the bottom of the editorial, 'participation in "inexpensive, small-scale, high-precision" experiments to study physics...
Hey booom0r, You mentioned that you are working on a small scale experiment to test beyond standard model physics. That's really cool. Which experiment are...
Hey Tom, I'm currently doing a high-precision measurement of the half-life and branching ratio of the superallowed beta decay of 10C. I'm based in Australasia...
Very cool. I believe some of my colleagues here at LBNL did some measurements on that for 10C back in 2001 using the gammasphere. Interesting stuff! As your...
Enter your vote today! A new poll has been created for the undernetphysics group: Which energy technology will be predominant in the future when fossil fuels...

Our Undernet Physics Yahoo Group turns 4 years old today! Happy Birthday! Thanks to everyone who participated in the group, especially those who stuck around...
I agree! Not everyone has access to big expensive accelerators, but I think if one is clever about it, one can still contribute to the field. I guess that's...
Hi everyone, Just voted in the poll and I see the majority of us are thinking Nuclear power. I'm just curious to see what people have to say about the new...
Not many member were willing to dig up their basic mechanics knowledge to do this, I suppose. ... The key thing to remember here is that for them to collide,...
... Stuart Freedman's weak interactions group at Cal/LBNL did the work a few years ago using Gammasphere. The first is a link to an LBNL report and the second...
OK, I have absolutely no idea how this will go down, and I have no clue if there's more than 1 possible answer to this one, but I'm going to give it a try...
... Hey Boomer, Do you know Paul Barker? Another postdoc here at LBL, Nikoli Tolich, was a student of his (working on other things) at the University of ...
Hey Tom, I am indeed working with Paul Barker, he's my supervisor for the 10C project. We were lucky enough to have Nikoli here in Auckland presenting a ...
Hello Can anybody help me with this question: A body stands on the peak of a triangle. What is the direction of the normal force? Is the sum of "lines" in this...
Hi, It sounds too much like a homework problem to me so I'm not going to answer it directly. But here are some hints: The body is standing still so from...
If you have a physical triangle that has some finite but small radius of curvature at the tip, then it's the same as two balls on each other. On the other...
very true but the simple equilibrium condition is suficient for describing the normal force. u don't have to say which atom is colinding with which, and...
I thought about it a bit more and I take back what I said about the normal force on the triangle. It's true that the normal is not defined at the point of the...
http://www.rochester.edu/news/show.php?id=2544 Something strange in this experiment. The animation 'backward light' looks impressive. Sort of subluminal...
... But this is almost the same thing as the pulse-shaping NEC experiment a while back, except that it uses negative refractive index material, thus the reason...
Hi, There is a tutorial for Green's functions at http://www.boulder.nist.gov/div853/greenfn/tutorial.html How does the subtitution of Fourier transorm becom ...
Are you asking why that's the representation of the Helmholtz equation in Fourier space? I suppose the way to do it formally is to multiply both sides of ...
Hey, I'm disappointed that more of you didn't take up this one! :) ... and ... A thermometer left in space will warm up until it is absorbing as much radiation...
These types of puzzles always annoys the hell out of me. :) BTW, you have 2 weeks to do this since I will be on vacation starting this Friday. Peter picked one...
Hi, He probably just made a mistake. The post with his answers have been deleted as well as the reply (since it quoted the original message!). Please remember...
