The one thing everyone should know about quantum mechanics #shorts

April 14th is #WorldQuantumDay. I am not a big fan of special occasion days but cannot not use the opportunity to tell you what I think everyone should really know about quantum mechanics.

studying quantum mechanics gave me a constant feeling of being as thick as a planck

"If it were not for quantum mechanics, we would all fall through the floor."
Specifically, Wolfgang Pauli had to publish his Exclusion Principle..
That is why, before 1925, everyone fell through the floor.
Imagine the inconvenience!

I think Sabine did it because YT shorts are the smallest unit of YT that you can publish, therefore this is a quantum YT video for quantum day.

One macroscopic effect of quantum mechanics that I like is the effect of three stacked polarizing filters.

After being ripped off so many times by my mechanic, I wouldn't trust any kind of mechanics.

Always great to catch your newest posts. I appreciate you and all the insights you share here. My dear Sabine 💛🥰

"Here's the big deal, sir. I'll bet any quantum mechanic would give his life for a chance to fool around with this gadget."
- Quinn, Forbidden Planet, talking about the Klystron frequency modulator.

Yep, quantum mechanics can do *everything*.

The one thing that everyone should really know about quantum mechanics is that IT HAS NOTHING TO DO WITH MENTALIZING GOOD THINGS TO MAKE THEM COME TRUE.

So when I studied physics in school well before I ever heard the words quantum mechanics, I was really studying quantum mechanics without ever knowing it.

Thank you for the humble but clarifiying statment

[archstanton_live]

Lol, what a sense of humor!!! My perception has been flopped. You are fantastic Dr.

[CosmosNut]

Thanks for another short and concise explanation.

As a rule of thumb, objects lighter than the Planck mass have an Uncertainty Principle based upon wavelike behaviour, while objects heavier than the Planck mass have an Uncertainty Principle based upon classical Brownian motion on the same scale. A detector always has some part of it in classical Brownian motion, which is what distinguishes a detection from a simple interaction. This rule of thumb can be turned into a working computer simulation which makes use of a random number generator. It cannot deal with everything, but it's a start.

If you can please upload more videos like this very very informative in short form

hello sabine, how are you doing? i was wondering, since you recently made a video about nuclear energy, if you could make one about thorium nuclear reactors. we hear all sorts of things about it, as if it were a miraculous solution for all our energy problems. perhaps you could give other points of view about it

Hi Sabine, one thing I don't understand is that if general relativity says that gravity is a property of the curvature of spacetime, what don't we know about gravity ? Why do we need gravitons ? Are those needed to explain gravity at the quantum level ?

[billb]

I like the idea that gravity is not a force... that would seem to explain some of the problems with it.
But the vision of emitting anti-gravitons from the deflector dish _is_ enticing.

I living in Brazil and I'm not a physicist, but I like the matter and I can aknowledge and appreciate a good channel!

good that ur there to remind us, you rock!
