No, it’s not a one way mirror. It’s much cooler than that. MIT scientists have invented a new invisible mirror that can show reflections like a typical mirror but also be see through like a window. The magic is in the alternating 84 ultra thin layers typical glass and tantalum oxide. It’s a mirror but when you spin it, it becomes transparent. Some light passes through, some light gets reflected.
Staying healthy is a lot like medieval warfare. Cells vs viruses. There are cells defending their castles and viruses trying to break through. If a sneaky virus manages to attack a cell, the cell fights it and notifies all the other castles about what to build to defend it. Man, learning about biology is so much easier when you have cute animations like this making it look like Game of Thrones.
Vsauce, the master answerer of life’s toughest questions and professional blower of minds, tackles something so philosophical in his latest video that you’ll start to wonder what in the hell our purpose is on this Earth. And if it’s any different than a purpose of a rock. It starts with the discussion of art and then fakes and forgeries of art and what forgeries really mean and what it means to be original and eventually leads into a discussion on how we’re pretty much all just forgeries too. What is real! Who is real! Nothing is. Damn. Sauce.
From this perspective and in their fully folded stow position, the Bell Boeing V-22 Osprey looks like a some weird spaceship concept. It’s amazing how these things fold. It’s fully automatic too. Here’s a video showing the process:
Ketchup, that delicious nectar of a condiment, is more annoying than it should be to pour out and enjoy. Why? Partly because of the dumb bottle it’s in but mostly because it’s a non-newtonian fluid in more than one way. Watch TED-Ed explain why it’s so damn hard to pour out and what you should do instead in this enlightening animation.
Sure, you know what food you’re eating, but you don’t necessarily know what’s in that food you put inside you. SITU is a food scale that doesn’t just measure weight – it offers up information about the nutritional value of the stuff you’re weighing, too. The Bluetooth-enabled scale talks to your iPad, listing any and all stuff you weigh as you go, with an… Read More
English isn’t the hardest language in the world to learn but it’s definitely a crazy one with wacky rules. Things that apply for some words, never seem to be considered for similar ones. Change one letter here and it can sound completely different there but sound the same somewhere else. It’s all pretty ridiculous.

If you’re still a little confused about why everyone is talking about The Big Bang and gravitational waves and cosmic inflation and space and twists of light and so forth, it’s okay. Much smarter people are taking care of answering those questions for humanity. But it’s a big effing deal so us less wrinkled brain humans should try and understand it too. How? Simple. With a towel, an apple and a ping pong ball.

According to physicists, there are three, er, two and a half different theories on how a person would die if they got sucked in by a black hole: stretched like a spaghetti noodle, burnt like a toast and maybe even scrambled. Nova PBS explains that if the argument on how people would die if swallowed by a black hole were to ever be settled, it would "revolutionize the fundamental laws of nature". Watch and learn why in the video below

I used to joke around about how I have learned so much more from YouTube than I ever did in school. I’m not joking anymore. Here’s a nice animation from Kurzgesagt that simplifies all you need to know about the Big Bang. It’s this type of education that plants a seed in my brain for future Wikipedia rabbit holes and YouTube note taking. All hail YouTube Class of 2014.
