Ah, now we know why the Doctor visits our planet so often. Via NASA’s website:
Einstein was right again. There is a space-time vortex around Earth, and its shape precisely matches the predictions of Einstein’s theory of gravity.
Researchers confirmed these points at a press conference today at NASA headquarters where they announced the long-awaited results of Gravity Probe B (GP-B).
“The space-time around Earth appears to be distorted just as general relativity predicts,” says Stanford University physicist Francis Everitt, principal investigator of the Gravity Probe B mission.
“This is an epic result,” adds Clifford Will of Washington University in St. Louis. An expert in Einstein’s theories, Will chairs an independent panel of the National Research Council set up by NASA in 1998 to monitor and review the results of Gravity Probe B. “One day,” he predicts, “this will be written up in textbooks as one of the classic experiments in the history of physics.”
Time and space, according to Einstein’s theories of relativity, are woven together, forming a four-dimensional fabric called “space-time.” The mass of Earth dimples this fabric, much like a heavy person sitting in the middle of a trampoline. Gravity, says Einstein, is simply the motion of objects following the curvaceous lines of the dimple.

Oops, how did this slip onto this blog…
This counts as “nerdy,” right?
SETI, the Search for Extra-Terrestrial Life, has shut down one of its satellite arrays after 90% of its funding was cut by NASA. Now we’ll never know they’re coming…
Why Old Books Smell Good
“Lignin, the stuff that prevents all trees from adopting the weeping habit, is a polymer made up of units that are closely related to vanillin. When made into paper and stored for years, it breaks down and smells good. Which is how divine providence has arranged for secondhand bookstores to smell like good quality vanilla absolute, subliminally stoking a hunger for knowledge in all of us.”
“The human heart stripped of fat and muscle, with just the angel veins exposed.”
Can you spot the photobomb? Look for it around 8 o’clock at the moon’s rim. Trollplanet is a troll. ;D
I had to post this. It’s already gone from the store, but TeeFury had this as a T-shirt for a while, and my absolute favorite heroine of all time has to be Samus Aran (pre-Other M, though, because I haven’t played it yet and I’ve heard they really turn her into a needy bitch or something). I love the Metroid series!

Jonathan Keats, a philosopher and artist, is offering to entangle partners on a quantum level in NYC from May 12th to June 18th. It’s absolutely free, so go take your beloved and entangle your photons! The process involves prisms and splitting light and all kinds of fun stuff. It’s totally harmless, go check it out! It’s mostly bullshit, but it’s amusing, romantic bullshit. (Wait…does romance come in any other form?)
Hey guys, since I lost a follower probably due to the spammination of Doctor Who on this blog, Cross-Section-of-the-Nerd, I’ve decided to split the blogs into my Nerd blog which will just report on science and nerdy things in a better balance, and a new Cross-Section of the Whovian blog to feature all things Whovian. So if anyone’s been following this blog for its DW content, wander over to that one instead, because there probably won’t be any more Whovian goodness on this one.
Unless I find something particularly adorable or awesome or Nerdy.
