Prof David Deutsch - Quantum Information in Many Worlds

[@GarryBurgess]

I had not heard of Professor David Deutsch until a few days ago. I'm so pleased to have discovered this brilliant scientist.

[@TheFlamingChips]

New David Deutsch! Thank you

[@El_Diablo_12]

Fantastic interview Mert, and it's always hugely valuable to hear what David has to say.

[@zombieinjeans]

Omg I love the host's reaction to the final question. He was like "well damn."

[@deeplearningpartnership]

Awesome!

[@mrjaysahli]

Welcome David!

[@mikebueno6379]

Great talk as always!

[@aaronsloman8406]

Very interesting and in some ways related to problems I've been working on about how hatching processes in eggs of vertebrates produce their results, creating new individuals with both enormously complex physiologies and also useful kinds of knowledge available for use shortly after hatching, without requiring any learning. I wonder whether Deutsch has thought about that and published something I could look at. A different thought triggered by this recording is that all the questioners were male. That worries me -- does it reflect on the current state of education in fundamental physics and how students are motivated to apply, or how they are selected, or ....??

[@brendawilliams8062]

The exact thing about history and time occurred also to me. That’s a tough one

[@FranAlbani]

Can someboy provide a link to something related to the "dictionary accounting argument"? It's ungoogleable.

[@alanforrester]

Unended Quest by Karl Popper, chapter 7 has related arguments.

@@alanforrester Thanks. That table in chapter 7 was very useful.

[45:13] What is wrong with probability?

[@schmetterling4477]

He is rambling. Frequencies are never equal to probabilities. That's just totally obtuse nonsense... even at the high school level.

I will comment stupidly. I study numbers. There is always light at the end of tunnel If you are drawn to it or propelled from it. I am no judge of that. The surrender of it is not voluntary. The measures I do not know.

Icke evidensbaserade teorier så inte mycket värda.

[@speedymccreedy8785]

Twaddle. The Multiverse is a belief, and as much as you want to believe in the god of the multiverse, Kermit the Frog, it doesn't make it a reality.

[@jamesalexander958]

David Deutsch wrote a paper about the multiverse where he invented quantum computing. How productive have your ideas been?

[@schmetterling4477]

@@jamesalexander958 David Deutsch didn't invent quantum computing. Feynman did. At least he was historically the first one who talked about it as far as I know. Not only that but Deutsch lost his mind. MWI is trivially false. If you read Everett's dissertation, then you can find the mistake in the second sentence. Everything that follows after that is absolute nonsense.

[@schmetterling4477]

He makes no sense whatsoever. There is exactly one world. ;-)

[@VoloBonja]

Sure and time flows

[@schmetterling4477]

@@VoloBonja Time is that which the clocks show. We try to teach that to the five year old kids. What flows is energy. ;-)

[@VoloBonja]

@@schmetterling4477 oh, than he does make sense about time not flowing.

[@schmetterling4477]

@@VoloBonja What about "A five year old child knows what time is." did you not understand just now? This ain't rocket science. This is people who think of themselves as intelligent not remembering trivial definitions.

[@VoloBonja]

@@schmetterling4477 your definition and the definition scientists are trying to expain are two different things. Time in physics and 5 yo time are different right?
