I also get nervous when i feel observed.
@ARTiculations
Omg I'm on the flooring dying 😂 every time I hear that tree falling scream. This collab is so awesome!!!!
@phs125
Electron must be shy. It has to obey the stupid rules of quantum society. When no one's watching, he does whatever he wants.

Well, now I'm all freaked out at what things are doing when I'm not looking at them! Looks suspiciously at pet fish
@azdgariarada
Thank you for teaching me that trees make anthropomorphic screaming sounds when they fall down. This channel is very educational.
@therealEmpyre
Even if you define sound in such a way that it is not a sound unless it is heard (which I don't), there are always animals around to hear a falling tree, even if it is just insects. Also, in the Shrodenger's cat experiment, the cat itself is an observer, so it will not be in a superposition of alive and dead. It could even be said that the Geiger counter that is set to release the poison gas is an observer, detecting whether radioactive decay has happened.

circa 6:10 Well you had to mesure them in some way, we see through electro-magnetic waves for example, so the very thing used to dectect the particles IS the thing that determined the state, while before it was the screen. what I'm saying is that the result changed not because we knowing where the particle went changed it (the electrons couldn't care less about who was looking at them), but because in order to mesure in the first place we had to do something to the electrons and THAT is what changed the thing. It's like waking someone to see if they're sleeping or just have they're eyes closed... if you wake them they are definitely awake XD
@nubbmarr
Ive heard it and read it several different ways, but this is the very first explaination of the double slit experiment that I think pretty much anyone could understand. Very good job
@gianfrancofronzi8368
Sounds are energy, and even when nobody is there to hear it , the energy is still happening.
@DrawCuriosity
I've loved both sides of the collab so much!! I really want to make that falling tree sound effect to be made into a ringtone... That way if someone rings and I don't hear it, then I guess no one rang me 😈
@cliffordhodge1449
For some people the analysis is a bit different, not touching on quantum physics analogies. The claim is that the tree does not make a sound unless there is an ear and brain on which the compression waves impinge. The fact that compression waves are a causal factor in producing in the brain the experience of sound, it does not follow that compression waves are the same thing as sound, a mental event. One might also ask if a pin prick in a thumb frozen with anesthetic is still painful, whether an empty house with nothing but a rotten egg in it has a foul smell, or whether the grooves and notches of a vinyl record sitting on a shelf are actually compression waves. They can help produce compression waves, but are not compression waves; the air in the house holds molecules of the rotten egg, but is not the rotten egg; and the pin prick causes damage to the skin, which could hurt, but does not. To compare with a different kind of wave, ask whether radio waves in a forest with no radio receiver still make music. If you think they do, try to provide an answer as to which radio station, which piece of music, or whatever is being played there. Each analogy involves contrasting two distinguishable things, and if you think about it, we may sometimes gloss over the distinction in casual conversation, but for technical or precise purposes, we are actually very much committed to the idea that the two things are distinct and not identical.
@stevekerp1
Shrodinger's cat comes to mind. This is one of those "paradoxical" questions where the answer can be changed by changing the definitions of the words used in the question. We don't really learn much about sound or anything else when we get to the answer. Ten minutes of fog. "Because if you define ...." at about the 2-minute mark.
@d9e240
Ladies! This is the greatest video on the topic. Thank you for covering all the options and explaining it so well and comical.
@wens6395
Popular "science" tends to compare apple with orange, and tries to reach some sort of "conclusions"…but fails to remind people that it starts with a analogy.
@JTheoryScience
The answer is YES. just for those that dont really understand how 'the measurement problem' works, it doesnt require observation from someone, just interaction, which can come from the other particles that its bonded to as a macroscopic, non-quantum state or even comes from its own non-local self interactions such as with the double slit experiment. this is the same type of thought experiment as the Shrodingers cat thought experiment. If fact, given the true quantum nature of reality its possible that it both makes and does not make a sound simultaniously, and that would be the case for a quantum scaled version of how sound works. also sound is more of a pressure distribution so it kinda needs lots of particle interactions to actually be a thing, much like temperature does. So i really think this tree falling in the woods thing is kinda just a rehashed and annoying version of the already misinterpreted, but slightly less annoying Shrodinger cat experiment. thanks for reading, please correct all my errors, YouTube community!
@AkashShaan
It was a great video. I already knew about the double slit experiment, that's what got me curious about quantum mechanics in the first place. But the way you presented it with the context of trees was really appreciable. I have to tell you I never gave sound this much thought, as I did after watching this video. You literally changed my own reality. I just have a question for you. Can you tell me the exact method by which the detector detected the electrons in the experiment ? I mean they have to interfere with the electrons in some way to force them to collapse into a single state.

3:15 - "We're essentially all living in our own virtual reality" yessss I try to remember this whenever I am communicating with people :)
@oneibus
Your channel is so awesome!!! My 8 year-old son have watched them all and he has a notebook full of diagrams he made from them. You explain things in such a great way, keeping it fun and interesting! Kudos! More, more, more!!! :)
