TED-Ed’s Andrew Zimmerman Jones provides a brief overview of the different ways in which physicists theorize how time and space relate, and ponders the question that time may not be a fundamental property of the universe, and only exists in our collective minds.
If you live somewhere that snow coats roads in the wintertime, you’ll want to check out Engineering Explained’s latest clip, as Jason walks us through the variables at work when driving on slippery surfaces, and provides some tips on how to maintain control on the snow.
Getting spaceships and satellites into orbit requires powerful rockets and all of the challenges that come with them. But would it be possible to use a giant cannon of sorts to shoot these objects safely into orbit instead? Curious Droid explores the possibilities.
A while back, a video made the rounds showing what was supposedly a flying phone case. We figured it was fake, but as Mark Rober and Captain Disillusion point out, it also scammed people out of cash. Keep an eye on Peter Sripol’s channel for his WORKING version.
While we’re certain there’s way more at play in the physics of space flight than EC Henry’s video mentions, it’s still interesting to learn about the relative speeds of various ships from the Star Wars universe, and what sort of drag coefficient their designs would result in.
More cars than ever are relying on electricity for propulsion, but using electric motors and batteries for aircraft poses challenges. Real Engineering explores whether a pure electric flyer would be possible, and why it’s so difficult to achieve. Caution, physics equations ahead.
In theory, energy consumed by a black hole is trapped forever. But it turns out it might be possible to harness the rotational energy of a spinning black hole to do everything from powering civilization to creating the biggest explosive device ever. Kurzgesagt explains.
Most of the aircraft have traditional wings or helicopter-style blades to take flight. But this contraption works very differently. Watch as an ingenious kid named Finley shows Essential RC his plane that takes advantage of the spinning Magnus Effect to stay airborne.
Engineer Mark Rober and teacher Al “Doc Fizzix” Balmer explain the physics of these primitive race cars that get their power solely from the energy stored in a mousetrap’s spring. Along the way, you’ll learn about the principles of mechanical advantage, levers, and wheels.
You never want to get too close to a mound of fire ants. But from the comfortable distance of your browser, they’re neat little buggers. Vox explores some of the fascinating ways in which colonies stick together to form structures, and how they can act as both a solid or fluid.
Destin from Smarter Every Day teamed up with Gav and Dan from The Slow Mo Guys to see what exactly happens when a bullet hits a piece of bulletproof acrylic, both with a bullet that can’t make it through, and then with a .50 cal that can. Watch The Slow Mo Guys’ video here.
Part of how CGI has gotten so much better in recent years is the development of systems for specific types of physical realism. Here Soeren Pirk demonstrates an amazing system designed for simulating the motion of tree branches, and the way wood burns when set on fire.
With the help of his fans around the globe, Destin Sandlin digs into a surprisingly deep and perplexing topic – measuring the steady state velocity of toppling dominoes. The slow-motion footage is fascinating to watch, and you’ll definitely feel smarter after this one.
It’s not too hard to travel faster than sound, but amping things up to the speed of light is a whole other level. Life Noggin pontificates on the what might happen if we could exceed 186,000 miles per second. The whole slowing down light thing seems like a cheat though.
