Wookiepedia says AT-AT walkers go at a top speed of 60 km/h (about 37.28 mph), but when you look at them in episode 5, they don’t seem to go that fast. So what’s the true speed of those walkers? watch this video from EC Henry to find out! [EC Henry]
Watch as Youtuber Mark Rober does the elephant toothpaste (aka slime foam) experiment on a very, very large scale. [Mark Rober]
Billions of years ago, simple organic compounds assembled into more complex coalitions that could grow and reproduce. At the time, Earth had widespread volcanic activity and a hostile atmosphere that made it almost devoid of a suitable environment for living things. So where did life begin? Luka Wright searches for the cradle of life that […]
Many forms of birth control are hormone-based–but not everything mixes well with those hormones. This week on Reactions, learn about some common products that could make your birth control less effective or cause dangerous side effects. If you have any concerns, be sure to consult your doctor.

From Mike: Here’s the first song in my Computer Science Rap series! I thought it would be a good idea to lay down some ground work before we get into coding. We get into questions like, what is code? Why do we write code? Who gets to write code? So let’s dive in and critically […]
We’ve seen plenty of time-lapse videos of stars moving across the sky. Aryeh Nirenberg took a different route and stabilized the stars, therefore showing how the earth moves relative to the sky. Images were recorded at 12-second intervals over a period of three hours. [via Boing Boing]
From Joe Hanson: I met Molly Burke a few months ago. She’s awesome. I absolutely love what she’s done on YouTube to bring awareness to living with disability, and turning it into ability. And her guide dog Gallop is awesome too! When Molly and I first met, we started talking about how she navigates the […]
Quantum computers could eventually outstrip the computational limits of classical computers. They rely on the behavior of atomic and subatomic particles, whose quantum states are incredibly fragile and easily destroyed— which is why this technology remains largely theoretical. How would quantum computers work, and are they really possible? Chiara Decaroli investigates. [TED Ed]
In this video from TED Education, discover the science of how viruses can jump from one species to another and the deadly epidemics that can result from these pathogens. [TED Ed]
This video is about how Albert Einstein made a mistake when applying the Field Equations of General Relativity to cosmology (in particular, to a static, constant density universe), and solved the problem by introducing the cosmological constant, rather than allowing for a dynamic universe with a scale factor – that is, the Friedmann-Lemaitre-Robertson-Walker universe, first […]
