I was rather hoping this would be a hawking radiation method, i.e. actually generating light using gravity

Looks really good, can't quite tell if it can interleave lines from several sources if not this would be an excellent feature.

I think this might be a daft question, but why can't they inject packets with a (roughly) appropriate TTL for the current sequence that they're hijacking? From the two examples shown one might think they're picking ttl's

in figure 7, Faradays Law: changing magnetic field in the left torus induces a variable current in the wire, then via ampere's law the changing current in the wire induces a magnetic field in the second torus. However in figure 8 while the

In which area of interest? As for journal access, i suggest using public computers in a university library. Not tremendously practical but they're always subscribed.

Yet another article about the parity breaking at rhic, i work in this field and while this would be very exciting it's not a cut and dry result. Running the numbers for the proposed theoretical cause of the parity violation leads to somethi

downloaded the linux version, nice music and it seems like it mostly takes place through bbs conversations which is great but its a shame you cant type the messages, just click. Fantastic music

don't forget the yang-mills mass gap and the navier-stokes initial value problem, both clay millennium problems and both rather important. Well the yang-mills one is probably more important, this list is a bit m-theory biased. I think the m

title is misleading, the gold nucleii collide to create the a quark-gluon-plasma (probably) which eventually cools and condenses to create these new particles which are made from regular old quarks and gluons like every other baryonic parti

I think the imaginary time should be taken as an indication that it doesn't make sense to talk about travelling at v > c, in terms of a Special Relativistic framework at least :)

The usual energy loss mechanism for cosmic-rays (fast protons) is reverse-compton scattering off the cosmic-microwave background photons, which is quite amazing really. Some of the most energetic particles scattering off the ubiquitous but

One of the authors, Baez, wrote "Gauge Fields, Knots, and Gravity" a lovely, cheap, and fairly accessible intro to applications of topology in mathematical physics. Worth a glance if you find yourself wondering about all this

check out "the structure and interpretation of classical mechanics" by sussmann et al for a whole raft of things like this done in scheme. I don't see why would you want to stay away from floats, using rationals isn't going to magically fix

Seems pretty clear to me, it doesn't claim to be an article for the non mathematically inclined. Not that "pop" articles on this subject wouldn't be pretty cool too.

I liked this but it really slowed things down. Perhaps because my home folder etc are all on nfs shares?

Nice. This helped straighten up my idea that svd is just eigenvalues for nonsquare matricies.

I'm all for the good things in modern life, dentists, technology &c &c and I don't believe that the author is explicitly against this either. Rather his main point was that we-the-people have been manipulated into thinking that the

Good resource, i had to start using R recently and most of the examples and books i found were of the "stats with R" variety which all emphasise how to just roll along with the library functions. The general advice i got from some statistic

string theory, if you look at it too cynically it's a high dimension optimisation process. edit: also the headline seems a bit over-dramatic it's not running out it's slowing down.

strange article, they seem to cite one example of the scary feds huting one guy down without really going into any of the details at all. Does fox have some kind of devolution agenda?
