xkcd creator Randall Munroe’s latest book offers solutions to real-world problems. But don’t expect to get advice you can actually use. Instead, you’ll receive overly-complicated and impractical methods, in what he calls “world’s least useful self-help book.” Drops 9/3/19.
Stanford mathematician Tadashi Tokieda explains a strange phenonmenon which occurs when tapping the inside of a coffee mug with a spoon – as it creates differently-pitched tones depending on where you place the spoon. More from Quanta Magazine. (Thanks Susan!)
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.
Kurzgesagt explores string theory, and how it attempts to explain the nature of the universe. It’s supposed to solve the incompatibilities between quantum and gravitational physics by describing particles as “strings” rather than points. Yeah, we’re still confused.
