"Books cannot be killed by fire. People die, but books never die. No man and no force can put thought in a concentration camp forever. No man and no force can take from the world the books that embody man’s eternal fight against tyranny. In this war, we know, books are weapons."
String Theory predicts the existence of more than the 3 space dimensions and 1 time dimension we are all familiar with. According to string theory, there are additional dimensions that we are unfamiliar with because they are curled up into tiny complicated shapes that can only be seen on tiny scales. If we could shrink to this tiny, Planck-sized scale we could see that at every 3D point in space, we can also explore 6 additional dimensions. This animation shows a Calabi-Yau surface which is a projection of these higher dimensions into the more familiar dimensions we are aware of.
Brian Greene’s book, The Elegant Universe, was made into a documentary and has a chapter that does a good job of explaining this concept. The Elegant Universe [documentary]
Can’t stop, won’t stop: Protesters in Ferguson rally again, seeking justice for Mike Brown. More than a month and a half after his death, his killer, Darren Wilson, is still a free man. (Pt 2)
Because it wouldn’t be a protest in Ferguson without fuckery from the police. A driver plowed his car through protesters, grazing several and running over a young boys foot. Beyond taking several hours to transport the boy to the hospital, they took even longer to arrest the motorist. Who did they not wait long to arrest? Two of the protesters who had been documenting the altercation for the world to see. If you’re not angry, you’re not paying attention. #staywoke #farfromover #nojusticenopeace
REMINDER: if you have a vagina and want to use Plan B as an emergency contraceptive, it loses effectiveness if you weigh more than 165 lbs (74.84 kg) and is completely ineffective for those that weight more than 176 lbs (79.83 kg) (x)
Whhhhat? Excuse me. Let me spread the shit out of this.
On Wednesday, at 12:10:27 GMT, ESA’s Planck space telescope ended its four and a half year mission when project scientist Jan Taube sent the command telling the unmanned probe to switch itself off. Called ESA’s “time machine,” the spacecraft was sent into solar orbit to prevent it from becoming a hazard to future space missions.
Launched on May 14, 2009 from the Guiana Space Centre in French Guiana along with ESA’s Herschel space telescope, Planck was sent to the Sun-Earth L2 point, where the gravitational forces of the Earth and Sun cancel one another out, allowing the craft to maintain it’s position. It was tasked with studying the Cosmic Microwave Background (CMB); the echo of the Big Bang that kicked off the physical universe.
Built by Thales Alenia Space, Planck’s cryogenically cooled instruments were more sensitive than any previously sent up to study the CMB and allowed the telescope to produce more detailed maps in the microwave and infrared spectra at higher resolution than was previously possible. Operating at a tenth of a degree above absolute zero, the telescope allowed scientists to look back to the beginnings of the Universe to about 380,000 years after the Big Bang.
Planck completed both its primary and secondary missions, which ended in January when it ran out of liquid helium to cool its main detector. But it continued on using its secondary instrument until the decision was taken to end the mission. In August, Planck was sent into solar orbit and instructed to fire its engine until all its fuel was expended. On Tuesday, the command was transmitted to deactivate it.
