Where no economist had gone before
. Paul Krugman posts a type-written paper on interstellar trade which he wrote as "an oppressed assistant professor" in the '70s. I do not propose to develop a theory which is universally valid, but it may at least have some galactic relevance.

Einstein TOR DVD
is a mostly animated feature film from the early 1920s, long thought to be lost, featuring animation from the incredible Max Fleischer
(who is responsible for the seriously cool Superman animated cartoons). For $15, looks like a must-have for animation buffs and science geeks.

Hyperdrive and a possible Unified Theory.
New Scientist article about a paper and proposal to NASA outlining development parameters and possiblities for a faster-than-light anti-gravity propulsion system, based on some rather interesting physics theories originated by a guy named Heim. You mean you've never heard of the Millenium Falcon? (via

Does dark matter exist?
Dark matter has been suggested as a solution to the galaxy rotation problem
where individual stars don't seem to rotate the way Newton's laws would predict. Now, some scientists are saying that observations fit with Einstein's general relativity, without any dark matter needed. I just find it amazing that no one has tried this yet.

Does relativity have any practical significance? In fact, relativity had to be taken into account
by the designers of the Global Positioning System. The GPS satellites are affected both by special relativity
(since the satellites are moving, clocks aboard them appear to run slower as seen from the ground), and by general relativity
(since the satellites are farther away from the mass of the earth, clocks appear to run faster as seen from the ground). The net effect of both is that clocks aboard GPS satellites would gain 38 microseconds per day relative to the ground, if relativistic effects were not corrected for--a figure which can be confirmed by using Google calculator
