zonde reacted to Ibix's post in the thread Undergrad Is GR superior to Newtonian gravity? with
Like.
I think that depends on what you mean by "reasonable", and whether Newtonian theory is better at it probably depends what you mean by... -

Yes, I agree with that. I thought we were discussing gravity, which is different because of curvature. Edit: note that ##a##, ##b##...

zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.Of course, it's stress energy tensor. Agreed Sum of the invariant masses of the parts of the system is not the same as invariant mass...

zonde reacted to PeterDonis's post in the thread Graduate Do any Bell papers plot raw data for non-entangled controls? with
Skeptical.
This isn't possible; that's not how SPDC works. Either you get a pair of entangled photons triggered by the input "pump" photon, or you... -
zonde replied to the thread Graduate Do any Bell papers plot raw data for non-entangled controls?.Experimentalists can't prove what you are asking for. Proving is for mathematicians. But there certainly are things that...

zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.Let's say ##a## is rest mass of 2 protons and 2 neutrons, ##b## is negative binding energy of ## ^4 He## nucleus and ##a+b## is rest...
-
zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.Look, if ##(a+b)## is scalar and ##a## is scalar how could ##b## be anything else but scalar?
-
zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.No I don't. Look, mass equivalent of nuclear binding energy is a factor in rest mass of the atom. If rest mass of the atom is Lorentz...

zonde replied to the thread Graduate Why is Bell’s theorem still considered controversial?.My answer would be that QM predictions are statistics based while real world observations are event based. Considering (at least for me)...

Haha.
Unlike Copenhagen/orthodox type interpretations, which function as "let's just hide ugly stuff behind vague words, so when someone... -
zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.Rest mass and binding energy are Lorentz scalars. You see, you can look at binding energy from two different sides: from one side you...
-
zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.Yes, it seems so. Okay, even if I would like to look at similarities between the two cases it would be stupid to say there are no...

Well, EM sources are a vector with both positive and negative time components, while gravitational sources are a tensor with a positive...

To emphasize this to @zonde, you can write the weak field metric in terms of the standard Newtonian potential, like I mentioned above...
-
zonde replied to the thread Undergrad Is GR superior to Newtonian gravity?.You won't be able to get away with this. Newtonian potential is literally a tool for calculating gravitational binding energy. So you...
