Photographing the path of light.
A new camera developed at MIT can photograph a trillion frames per second.
Compare that with a traditional movie camera which takes a mere 24. This new advancement in photographic technology has given scientists the ability to photograph the movement of the fastest thing in the Universe, light.
The actual event occurred in a nano second, but the camera has the ability to slow it down to twenty seconds.
The amazing camera.

For some perspective, according to New York Times writer, John Markoff, "If a bullet were tracked in the same fashion moving through the same fluid, the resulting movie would last three years."In the video below, you'll see experimental footage of light photons traveling 600-million-miles-per-hour through water.
It's impossible to directly record light so the camera takes millions of scans to recreate each image. The process has been called femto-photography and according to Andrea Velten, a researcher involved with the project, "There's nothing in the universe that looks fast to this camera."

Because who can keep up with which laundry settings is for which item, anyway?
Once upon a time, our only option for getting clothes clean was to get out a bucket of soapy water and start scrubbing. Nowadays, we use fancy machines that not only do the labor for us, but give us free reign to choose between endless water temperature, wash duration, and spin speed combinations.
Of course, here’s where the paradox of choice comes in. Suddenly you’re second guessing whether that lace item needs to use the “delicates” cycle, or the “hand wash” one, or what exactly merits a “permanent press” cycle. And now, you’re wishing for that bygone bucket just to take away the mental rigamarole.
Well, you’re in luck. Turns out there’s only one setting you actually need. At least according to one laundry expert.While appearing on HuffPost’s “Am I Doing It Wrong?” podcast, Patric Richardson, aka The Laundry Evangelist, said he swears by the “express” cycle, as “it’s long enough to get your clothes clean but it’s short enough not to cause any damage.”
Richardson’s reasoning is founded in research done while writing his book, “Laundry Love,” which showed that even the dirtiest items would be cleaned in the “express” cycle, aka the “quick wash” or “30 minute setting.”
Furthermore the laundry expert, who’s also the host of HGTV’s “Laundry Guy,” warned that longer wash settings only cause more wear and tear, plus use up more water and power, making express wash a much more sustainable choice.
Really, the multiple settings washing machines have more to do with people being creatures of habit, and less to do with efficiency, Richardson explained.
“All of those cycles [on the washing machine] exist because they used to exist,” he told co-hosts Raj Punjabi and Noah Michelson. “We didn’t have the technology in the fabric, in the machine, in the detergent [that we do now], and we needed those cycles. In the ’70s, you needed the ‘bulky bedding’ cycle and the ‘sanitary’ cycle ... it was a legit thing. You don’t need them anymore, but too many people want to buy a machine and they’re like, ‘My mom’s machine has “whitest whites.”’ If I could build a washing machine, it would just have one button — you’d just push it, and it’d be warm water and ‘express’ cycle and that’s it.”
When was the last time you washed you washing machine? "Never" is a valid answer.

According to Good Housekeeping, there are some things to keep in mind if you plan to go strictly express from now on.
For one thing, the outlet recommends only filling the machine halfway and using a half dose of liquid, not powder detergent, since express cycles use less water. Second, using the setting regularly can develop a “musty” smell, due to the constant low-temperature water causing a buildup of mold or bacteria. To prevent this, running an empty wash on a hot setting, sans the detergent, is recommended every few weeks, along with regularly scrubbing the detergent drawer and door seal.
Still, even with those additional caveats, it might be worth it just to knock out multiple washes in one day. Cause let’s be honest—a day of laundry and television binging sounds pretty great, doesn’t it?
