This is incredible. Watching the duality of light in super duper slow motion! Awesome! Science rules!
In 1964 MIT professor Harold Edgerton, pioneer of stop-action photography, famously took a photo of a bullet piercing an apple using exposures as short as a few nanoseconds. Inspired by his work, Ramesh Raskar and his team set out to create a camera that could capture not just a bullet (traveling at 850 meters per second) but light itself (nearly 300 million meters per second).
Stop a moment to take that in: photographing light as it moves. For that, they built a camera and software that can visualize pictures as if they are recorded at 1 trillion frames per second. The same photon-imaging technology can also be used to create a camera that can peer “around” corners , by exploiting specific properties of the photons when they bounce off surfaces and objects.
Among the other projects that Raskar is leading, with the MIT Media Lab’s Camera Culture research group, are low-cost eye care devices, a next generation CAT-Scan machine and human-computer interaction systems.

“Though photographs in the near future will still be composed by people holding cameras, it will gradually become more accurate to say pictures were computed rather than ‘taken’ or ‘captured.’”Popular Photography magazine
Photographer Michael Chrisman used a pinhole camera fitted with photosensitive paper to make a 365-day exposure of the Toronto skyline from Jan. 1, 2011, to Dec. 31, 2011.
A lovely year-long exposure of the Toronto Skyline made with a pinhole camera. Over 365 different streaks of the sun as they slowly pass the sky creating the streaks.
I’ve TRIED to make a pinhole camera myself and it is not easy – this is super impressive.
The camera, a simple black box, was mounted to the side of a rusty metal box next to a shipping beacon near the shipping canal. Chrisman used tape and a few bricks to “secure and position the camera for its long wait,” he said in an email exchange with the Star.
Chrisman, a 31-year-old freelance editorial and art photographer, put it there on Jan. 1, 2011, knowing a lot could go wrong. Mishaps could include the camera being stolen, which has happened in some of his earlier time-exposure experiments.
Look at me go! Writing another blog post! There’s just a few things that happened today/a few days ago that are worth posting!
Also – hit play on this video and then read the below stuff. Just a little mood music to make your reading experience that much more enjoyable. Look at me, a multi-media blogger.
If you didn’t hear, NASA made a big announcement about extraterrestrial life today. I borrowed this from io9.com it’s Everything You Need to Know about NASA’s completely new life-form.
What is the discovery?
The discovery, made by NASA scientist Felisa Wolfe Simon and her team, is straightforward enough. We often think of carbon as the crucial element for life, but actually there are six elements that work together as the basis of every last organism we’ve ever found. These are carbon, oxygen, hydrogen, nitrogen, sulfur, and phosphorus. Phosphorus is part of the structural framework of DNA and RNA, essentially acting as the molecular girders that hold everything else in place.That makes phosphorus essential to the stability of DNA and, in turn, the existence of life.
Wolfe Simon investigated whether a different element could be substituted in the place of phosphorus. The obvious place to start is with arsenic, which is directly below phosphorus on the periodic table and thus shares many of the same properties. Her team headed to California’s Mono Lake near Yosemite National Park. Mono Lake is an incredibly unusual ecosystem, with three times the amount of salt as seawater and, crucially, it’s poor in phosphorus and rich in arsenic. Despite this, life thrives in Mono Lake, and so the team collected some microbe-rich mud and took it back to the lab.
There, they placed mud in a setting where the microbes would have everything they needed to live, such as sugar and vitamins. Crucially, however, they created a phosphorus-free environment and pumped the test area full of arsenic. Nothing should have survived in those conditions – indeed, arsenic is notoriously toxic. But the microbes didn’t just survive, they actually thrived in the seemingly impossible conditions.
Essentially, instead of things needing phosphorus to live, they can now use arsenic, which is found abundantly in our galaxy. So this proves that there is a bigger chance of things being out there. So yay!
In other news that no one I know cares about. Lebron James came back to Cleveland after being a dick in the off season. He got booed lots. Big deal.
