decoherence explains why observers see an illusion of a collapse as they become entangled

the wavefunction never truly collapses, thats why i say many worlds makes more sense

or consistent histories

@glamp in a way, he is saying there is an alternative theory.

it cant explain something that doesnt happen... wavefunction collapse is an illusion only true from an entangled observers perspective

I plan on reading a chapter a day.

@Rogal Dorn what book are you reading?

"A First Introduction to Quantum Physics" by Pieter Kok. It's a textbook.

I got a pdf though.

oh

yes, that's a good one

Kok

sorry

is it good

I want to understand it as well as an undergrad on the subject would understand it.

All QM interpretations are untestable as they make the same predictions but certain interpretations may be favored for reasons such as Occam’s razor. I prefer many worlds because it has one less postulate, the postulate I’d wave function collapse

you should know a little bit of calculus, some linear algebra, and a bit about complex numbers though

before you read it

I know some calculus. I might know some linear algebra from a fresh stats class.

Feynman explains it about as well as it possibly can be with minimal math in his QED series

I haven't looked at calculus in over 20 years

algebra is everywhere though

Susskind also has a great series, “The theoretical minimum”

I do calculus all the time for fun

calculus is the science of zooming in on shit until they appear straight/flat

i was good at math until that

@glamp what’s the answer here

you know what, i think it was cause of a women teacher

my horones wanted me to look at her rather than listen

So where's my hovercar dammit!?

Hit me with this absurd integral

What method did you use to integrate that if not numerically

You’re not a true calculus nerd until you think about the difference between riemann and lebesgue integrals

Here @Daddy

I would just use numerical methods

I mean the answer is C no doubt

where are the vraibles in the answer, are those variables known?

No it’s trivial to solve

But getting there rigorously
