Here is a paper that talks about quantum gravity modifications to the Heisenburg uncertainty principle. It’s neat b/c it allows for a minimization of the measured length to be quantified and sets up a situation where someone with enough time, money, or graduate students could conceivably test the hypothesis and put upper bounds on Quantum Gravity.

Isn’t it amazing how I said I would do one thing, and have done just about everything else instead?

From the number of anon postings I have, I guess most of you have figured it out already. Happy posting!
I’ve decided to solve the Goldbach conjecture. I’ll be away from my blog for a while.
Sorry.
Introductions to Supersymmetry
Here are some good internet articles and pages on understanding supersymmetry. The arxiv articles are a little dated, but still good.
Some references for ya. Wikipedia, I know…
Clue and dinosaurs. What a combination.
Around a rotating black hole described by the Kerr metric,
This metric is equivalent to a co-rotating reference frame that is rotating with angular speed Ω that depends on both the radius ”r” and the colatitude theta
we see there are two solutions. The first solution is the event horizon of the black hole 
Within this block, we find that 
In 2004, Gravity Probe B was launched, and one thing they did was examine frame dragging, however, the data still has to be analyzed.
It is natural to ask what happens to space as we wind it up in the ergosphere, seeing as spacetime is smooth at the level of GR.
At the quantum level, it is postulated that spacetime comprises of a “foam” that flows smoothly around itself, unwinding the frame dragging effects as spacetime moves away from the black hole.

Tommaso Dorigo has set up a page that explains the basics of experimental particle physics.
When torturing scientists it is better to use chess and unsolvable problems then waterboarding and finger smashing.
During WWII, the US government understood the need to get German scientists and engineers before anyone else did, so we could use their tech and knowledge to advance our own. Maybe I’m being old and bitter, but it seems like nowdays no such thing would happen. I would be easier to capture, and torture them for some knowledge, then shoot ‘em.

I just came across this article in Wired, detailing how a newly discovered rainforest fungus creates a diesel like fuel.
The fungus, Gliocladium roseum is detailed in the Journal Microbiology.
IF this plant can be harvested and grown commercially, it may help alleviate the oil situation. With the advent of solar power, and this plant providing oil for plastics manufacture, we could reduce our dependence on foreign oil greatly.
