Ooookay! This is now getting even more interesting. For those of you who have been following the saga of the poor fine structure "constant", here is another...
Humm.... Frisbee must be out of fashion nowadays. We didn't have plenty of attempts on this one. ... well. The principle is the same as an airplane wing -...
This week's vexer requires you to be deligent in working out the details of a problem. The base of a tub is square with sides of length 1 meter. It contains ...
Some of you may recall this topic from a few months ago. As a reminder, I mentioned that I was doing photoemission on Mg using photons with energy (3.3 eV)...
Ok.. I almost typed "Einstein's BOXERS" there in the topic a second ago, but this certainly isn't about his undergrament. http://arxiv.org/abs/quant-ph/0404016...
Since the largest percentage of our members here are physics undergraduate students (per our Poll), I thought I'd post this. College students should check out...
Hey, another doable problem gone to the dogs! ... contains ... the ... the ... Denote the dimensions of the block by a, b, and c. The total volume of water is...
In many cases in physics, the force acting on a system has a dependent on displacement. An example of this is the simple harmonic oscillator, where F = -kx,...
... Hey Tom, Have you managed to tinker your way toward any new insights? Over at bell_bohm, Travis Norsen is unconvinced of my conclusion (that Alice and Bob...
Hi David, ... and ... -- ie get a step ... I'm sorta stuck. Glad you got back to me. I'm having some "email issues" (servers dying etc.). I actually composed...
... Hey Tom, Well if you happen to find your email, send it too me, even if it's wordy -- I'd be interested. Re: KG/Dirac. Perhaps it would be worthwhile to...
* Hey all, There are lots of illustrations of quantum nonlocality in the literature that we have all run across that take the form of a game of some sort,...
As a side note, in our Links section under Quirky Odds and Ends folder, libwasme posted a rather amusing link to an illustration of Bell Inequality applied to...
... Hey Zz, The above situation would not be non-local. There's really nothing strange or counterintuitive at all about it -- it behaves just like we would...
... OK, having thought about it some more, I think the setup of my previous post could be explained like this: one coin is "preprogrammed" to come up the same...
Hi straycat, ... I like the overall approach and think there is great potential for pedagogical value. The questions at the end are particuarly nice and drive...

Hi David, ... Be careful. Don't throw the baby out with the bath water here. The distinction between quantum versus classical correlations will not emerge in...
"ZapperZ" ... I agree! But I think is a matter of definitions, not a matter of words. ... Non-Locality. Given any two space-like separated systems, A and B, ...
Making citations and references to various papers in peer-reviewed journals would be a lot easier if everyone here has access to them. Unfortunately, this is...

Hi David, ... What you say may be true (re: not enough dof). However, if the heads/tails or win/lose basis isn't rich enough, then dead/alive isn't either --...
... This web page seemed a little cryptic and incomplete to me. Here's a bit of amplification as to how that mathematical inequality probably applies to...
Another surprise. With a large number of physics undergrads in here, I would have expected more people to try this. After all, this vexer was directly relevant...
This week's vexer is a bit morbid, but maybe that will get more people to participate. The Chompem Cannibals of the Island of Undernet Physics have the ...
