Edward Teller - Schrödinger's cat: I don't need to look (28/147)

[@RoverT65536]

The next video in the playlist tells why he doesn’t have to look.

Teller was the cat

[@NisseOhlsen]

0:59 he meant: 'The position of the particle and it's derivative', or r(t) and dr(t)/dt

[@MrFujinko]

its derivative in respect of time, just for the sake of completness

[@-danR]

That took me by surprise. I guess he was getting a little older. At 1:20 he fixes it.

[@richinoable]

Sensitive dependence on initial conditions?

[@Upgradezz]

What's does he mean to say" I don't need to look"?

[@rhomaioscomrade]

He means that an observer is not defined as a sentient being actively making an observation. The act of observation is technically defined as any physical system or process that interacts with the quantum system at hand and provides observables like energy or momentum. The counter and the cat are classical systems that interact with the alpha particles and cause the wave function to collapse regardless of our own observation. There is no reviving or killing the cat by looking - the cat's own "observation" determined its fate. Then we can simply interpret the uncertainty as just a regular case of odds for or against something; in this case the cat dying.

@@rhomaioscomrade Any physical system, which interacts with the cat, will get into the same superposition. All systems are quantum systems. Classical systems just exist as approximations. For a collapse to occur, you need the observer, which observes what has happened and then updates the wave function. Yes, quantum amplitudes gradually turn into classical probabilities which is callled decoherence. But yes, maybe he wants to say, that the obsever is only needed to check the probabilities and it is hard to imagine, how you can formulate a fundamentally probabilistic theory without referring to observers.

Nuclei and line-of-sight superposition Fluxions correspond in logarithmic condensation wave-packaging formation, e-Pi-i orbital-orbits interference, holography. Therefore "The Observer" is this Universal Holographic 1-0-infinity Entanglement Resonance, a sum-of-all-histories, Eternity-now omnidirectional-dimensional self-defining coherence-cohesion objective.

[@morpher44]

i don't need to look : ah. the cat is the observer

[@dougr.2398]

Am I?

[@dougg1075]

Doug R. Yes

[@RK-fr4qf]

Subtitles would be great

[@frun]

There's a transcript in description.

[@ray.shoesmith]

English is hard to understand

[@ghostmanscores1666]

A tree falling in the forest makes a noise. It doesn't need me.

[@HyperFocusMarshmallow]

In the asymptotic future I hope we’ll all just learn the Everett interpretation in kinder garden…

[@MariusRiley]

: I do not. For my money, it's a fairy tale made up to get out of looking any further.

[@Sharperthanu1]

The cat is a consciousness that collapses it's own wave function.That's why the speaker in this video doesn't have to "look."

[@urosuros2072]

Im not sure why do people keep using the term conscious, if you put unconscious camera inside and leave it to film it , system will behave excatly like concious being was observer Implying that consciousnesses dosnt mater Interactions are what matters

[@bill_lumbergh]

No the human outside the box is part of the same system. The box isn’t a closed system. it’s already collapsed

Truly living up to your username..

Of course one doesn't need to look, it is the interaction of the quantum state with any force or field that flips the uncertainty, so the cat is of course never in two states. I am surprised a man as smart as Schroedinger came up with this ridiculously dumb and false thought experiment.
