Dale replied to the thread Graduate How valid is the Block Universe theory?.I disagree with this. I can write the position of a particle as ##(x(t),y(t),z(t))## or... -
Dale replied to the thread Graduate How valid is the Block Universe theory?.I haven’t seen any different replies. They have been remarkably consistent. Can you point out what replies you thought were in...

Dale replied to the thread Graduate How valid is the Block Universe theory?.I am sure that there are more than this, but the two main interpretations of relativity are the block universe and the Lorentz aether.

Haha.
Oops. I had to go back and edit that post about 3 times because I kept making mistakes. Too early in the morning maybe? Oh well, what's... -
Dale replied to the thread Graduate How valid is the Block Universe theory?.I always feel that the overemphasis on “observers” can naturally lead to this kind of a misunderstanding.

Dale replied to the thread Graduate How valid is the Block Universe theory?.I think you mean 83 ps. The speed of light is about 30 cm/ns, so 2.5 cm must be less than a ns.

Dale replied to the thread Graduate How valid is the Block Universe theory?.Which specific implications? Some are probably parts of the interpretation (optional) but some are probably parts of the theory (not...

Dale replied to the thread Graduate How valid is the Block Universe theory?.The block universe is a specific interpretation of the theory of relativity. Like all interpretations, it makes no experimental...

It's an interpretation, so not testable as far as we know. It's far and away the most popular interpretation, and fits well with the...

Dale replied to the thread High School Confusion about one of Maxwell's equations.Correct. It can be slightly different because in one case an accelerometer will detect that one is accelerating and in the other case...

Dale replied to the thread High School Confusion about one of Maxwell's equations.I wouldn’t say “most cases”. In very many cases you do have changing magnetic fields.
-
Dale replied to the thread High School Confusion about one of Maxwell's equations.That is correct. The EMF in the wire is not due to an E field. The EMF in the wire is due to the Lorentz force on the charges in the wire.

Dale replied to the thread Undergrad Capacitor Voltages at t = 0: Zero or Split?.Yes. In other words there is no real-valued solution to the problem. I am not sure why you say “Norton” here. It is Kirchoff’s current...

I had not understood that the OP was specifically asking for the value at t = 0. In the general case, if one modifies the circuit in...
