So it is a mistake in the video. Many Thanks Indeed everyone! Happy to close the thread if that's the normal protocol.

This Veritasium video https : / / youtu.be / XRr1kaXKBsU?si=zNqHwmCTq-cmcsbW (spaces added in case there's an issue with posting URLs) at 13:04 makes a statement which I can't get my head around. Veritasium videos always seem to be well researched so my working assumption is it's my lack of...

Thank you. That makes complete sense now. Happy for this thread to be closed!

I'm watching the Stanford University Lecture series: Einsten's General Theory of Relativity presented by Leonard Susskind (who incidentally has to be one of the greatest educators I've ever watched). Whilst deriving the basic divergence equations relating acceleration, mass density, and...

PS... the spinning/flipping nuts in Zero G you can see linked bottom right in that first video to is also fabulous; makes a very unintuitive topic quite reachable

Hey A.T. - I've watched plenty of Gyroscope vids in my time and I have to say that first one is superb - I've seen the Veritasium one before but not the first one. Excellent find!

Hi Sayetsu There are literally hundreds of videos you can find; the challenge is finding the "good" ones - which will differ for most people depending on background etc Based on your question I would try these two (in this order) Special Relativity (E = mc2) Explained...

Thank you - this has really helped.

Thanks again Hutchphd. I've been doing some more reading based on what you've said and I have one final (I think it's final anyway) question on the tail that extends into the lower index medium. From what I've read, this evanescent tail extends but does not propagate into the lower index...

Thanks hutchphd; i have to say that's not what I had expected! How is the reduction in reflected beam intensity / increase in evanescent wave intensity explained in classical physics?

I've been reading into - and watching videos on - FTIR as an explanation of Quantum Tunnelling. The articles and videos I've watched switch between classical and quantum systems so frequently its left me with a question I can't find an answer to - the texts that seem like they might answer it...

It was part of the question, but location is the other part. The lack of symmetry that never seems to be addressed in the non-academic texts that I have been (self) limited to, is that the "birth" of entangled particles always seems to have to involve very local processes (even during...

Thanks for taking the time to reply EPR. I certainly wasn't suggesting there was anything questionable, just that in the explanations I've read (that have been limited to non-textbook articles and books), there has always been local interaction to kick things off. PeroK has kindly pointed out...

Thanks PeroK - definitely my very clumsy wording to use the phrase "same place"! It's probably one of the many issue with limiting reading to non-textbooks; in all the books and articles I've ever read on entanglement, the starting point is always something that happens "at very short distance"...

Thank you! I have a feeling I'm making a rookie mistake of trying to treat light as an EM wave and a photon at the same time... In my head I am following the EM diagram and thinking "at that point there where the E & M components cross the axis, where is the <whatever> in the photon?" The string...
