Hi Video, ... I am referring to "the wave function of the universe", which is symmetrical in time. So for all the the events you describe, there are ...
YOWZAH! This is another one of those things that I thought wasn't too difficult. Again, I was wrong.... or maybe people are just distracted by all the...
This week's vexer is just a plain, mindless entertainment. When Sid Bone was murdered, in a rather compromising position, Inspector Twiggit suspected Sid's...

Hi George, The purpose of pure science is to answer the question "Why?" and the traditional method is backward time evolution. A wave equation (is that what...
This paper has finally appeared in PRL with the citation B. Hessmo et al., PRL v.92, p.180401 (2004) .. but you can also get the preprint on arXiv at ...
I think this is an appropriate time to remind everyone of our rules and guidelines posted in message #1, as pointed to in the main page of our website. Trying...
Today marks the 2nd year anniversary of our Undernet Physics Yahoo group (and to think that Toro said it will never last....). I would like to thank all the...

Back from the dead... Being still an undergrad and not the smartest one at that, I have not learnt many too complex equations, so here are some of my favourite...
Stoke's Theorem: (this is a mathematical one) Integral loop f.dl = Integral surface curl(f).dA Tells us the surface integral of any curl(f) depends only on the...
It is appropriate that, while we're talking about the greatest equation ever, I point out a new link in our collection. In the Links section of our website,...

Time to put on your physics thinking caps once more... A particle that hangs from a spring oscillates with an angular frequency of 2 rad/s. The spring is...
Hi Video, I'm back from my trip, so I can finally reply. :-) ... Yes. ... Agreed! However, we were discussing MWI, and there are no initial conditions...
A physicist at the State University of New York, New Paltz has produced a quantum "hide-and-seek" game called Quantum Focus. Can you find the red, blue, and...
One aspect of quantum entanglement is that all the particles that are entangled are described by QM is ONE single particle,i.e. one cannot write the state...

OK, more follow up to this saga, and more woes to the Arkani-Hamed et al. predictions and String theory. At the recent APS April meeting, a team from...
