weirdoguy replied to the thread B The work done by two objects on each other.You don't seem to be aware that throwing out established terminology will make it even worse. They will not get it even more. Physics is... -
weirdoguy reacted to jbriggs444's post in the thread B The work done by two objects on each other with
Like.
You seem to have a problem with using the words "on" and "by" when speaking of the work done by a force. As if the distinguishing... -
weirdoguy reacted to sophiecentaur's post in the thread B The work done by two objects on each other with
Sad.
So why use 'on or by'? The work is already determined by the sign you have chosen and that will determine the behaviour (acceleration /... -
weirdoguy reacted to PeroK's post in the thread A The Causal Bootstrap Paradox in General Relativity with Like.
My take is that the argument is at best philosophical and in any case irrelevant to the physics. The search is for a quantum theory of...

weirdoguy reacted to Owe Kristiansen's post in the thread I Intuitive look at bending of light by gravity with Sad.
Cool formula, I think in terms of energy preservation. Whether it is frequency, mass, potential or kinetic energy. Vibrations...

That is no reason to conflate them. Yes, from these two you can compute work. This has been explained to you so many times in previous...
-
The sign of work doesn't just depend on the reference frame, but also on whether the value represents work done by A on B, or by B on A...

weirdoguy reacted to A.T.'s post in the thread B The work done by two objects on each other with Like.
If you are not clear about what is doing the work on what for the work quantities you define, then you are not being scrupulous.

weirdoguy replied to the thread I Reframing Light Bending Using Density Instead of Radius.Don't look at the formulas, look at the whole story!

weirdoguy reacted to Owe Kristiansen's post in the thread I Reframing Light Bending Using Density Instead of Radius with Like.
Ok, I am looking at the general and special relativity formulas now.

weirdoguy reacted to sophiecentaur's post in the thread I How does the electron come back down in energy level after absorbing a photon? with Like.
Just what is your point here? Can you show me just one formula in which 'colour' is used in any other study but colour analysis /...

weirdoguy reacted to hutchphd's post in the thread Potential difference defined in non-conservative electric field with Like.
I don't think so. The comment was to "just put a Voltmeter on it to measure V12" This is exactly what Lewin was warning against. It...

weirdoguy replied to the thread I Reframing Light Bending Using Density Instead of Radius.But we are doing physics, and newtonian physics does not work in this context.
