Like.
For massless fields with spin 1 or more, we can't construct position operator, so one can't think about photons traveling along any path... -

It has been discarded from modern quantum physics a long time ago (even though pop-science still talks about it). It has been discussed...

bhobba replied to the thread Undergrad Are classical optics and quantum mechanics double slit experiments fundamentally the same?.It isn't. Its resolution in QM is actually deep. Here is a deeper explanation: https://arxiv.org/abs/quant-ph/0703126 Even that is...

If you really think my problem is “basic math”, then it’s on you — for not understanding it and for this passive-aggressive argument...

To measure a quantity requires Energy, which is a function of Wave Energy (power times observation time) and Power is Amplitude Squared...

Good point here. Calculations with scalars don't seem to give the same awkwardness; we are very familiar with elementary school...

I'm not sure what this question even means. In actual experiments, there is no such thing as "quantum interference pattern" vs...

Thread has pretty much run its course, so it will now be closed. Thanks folks.

My problem with Cox is that during any talk he gives you can pretty much count on him turning to the audience and confidently...

One of the things that sparks public skepticism is when scientists with expertise in one area use their authority to make pronouncements...

Well this makes sense to me since the government is largely responsible for and leading the way on these issues. If I wanted a better...

I disagree. Mathematics is based on logic derived solidly from the axioms and stated assumptions. The logic is not "bent" to fit...

bhobba replied to the thread How good is Brian Cox as a science communicator?.Just for context, Malcolm Roberts here in Aus is well known as a bit of a loose cannon. Surprisingly, he actually is a qualified...

i.e. when we have found a working model We really don't need an apologist for Maths but, as it's based on axioms, it doesn't need...

bhobba replied to the thread How good is Brian Cox as a science communicator?.That's an old discussion. Feynman certainly agreed with you. My counterexamples are that mathematical physics is a branch of...
