Footnote †: Unstable Equilibrium

This video is a footnote for the video about the ring around the earth: https://www.youtube.com/watch?v=4xSPlQUejd8 Essentially, a ring around the earth is in unstable equilibrium, so it would stay put, but then fall one way or the other as soon as any asymmetry (even thermal or quantum fluctuations) developed.

Ring AROUND the Earth?

Thanks to http://www.squarespace.com/minutephysics for sponsoring this video; you can use offer code MINUTEPHYSICS at checkout for 10% off your first purchase. This video is about what would happen if we built a giant ring around earth – what would happen to the ring, that is. Would if fall? Collapse? Start spinning?

How Do We Know The Universe Is ACCELERATING?

Support MinutePhysics on Patreon: http://www.patreon.com/minutephysics Aatish Bhatia helped write this video! A big thanks for his help! Here's his blog: http://www.empiricalzeal.com The universe is expanding – this we know from looking at red shifts of distant galaxies – but the acceleration of the universe's expansion is harder to measure. It requires measuring the change of recession velocity over time, and it's done by comparing Type Ia ...

Can We Survive Curiosity?

There's a March for Science happening all over the world: http://marchforscience.com This is a video about how science is both inherently political and apolitical. And how hopefully we won't end up in nuclear war...

Should You Walk or Run When It's Cold?

Hi! My name is Henry, I make MinutePhysics, and you can support me on Patreon: http://www.patreon.com/minutephysics Is it better to walk or run when it's cold out? If you run, then you have to deal with wind, wind chill, etc, but your body generates more heat. If you stay still, standing or walking slowly, you don't generate as much heat, but don't deal with the wind. Note: the simple calculations in this video don't very well take into accou...

How to Teleport Schrödinger's Cat

Support me on Patreon: http://www.patreon.com/minutephysics Previous video on No Cloning: https://youtu.be/owPC60Ue0BE How to teleport Schrödinger’s cat: this video presents the full quantum teleportation procedure, in which an arbitrary qubit (spin, etc) is teleported from Alice to Bob by way of a pair of particles entangled in a bell (EPR) state and the transmission of information via a classical channel. Thanks to everyone who supports M...

The No Cloning Theorem

Support MinutePhysics on Patreon: http://www.patreon.com/minutephysics Three Blue One Brown: https://www.youtube.com/channel/UCYO_jab_esuFRV4b17AJtAw Why you can’t clone Schrödinger’s cat: this video presents the full proof of the “No Cloning” Theorem in Quantum Mechanics – without any fancy math! (stereotypical qubit has been replaced with Schrödinger’s cat). The full proof relies on the linearity of quantum (aka unitary) transformations, ...
