-
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.

That is his style these days ... get on TV and pontificate about things he knows next to nothing about, He loves being treated like an...

weirdoguy replied to the thread I Compact manifold cannot be represented by (single) parametric equation.All definitions of parametrization I were taught were having an open subset as a domain. I checked lecture notes of my superivsor (link...

weirdoguy reacted to dark_matter_is_neat's post in the thread A Scattering cross section between charged particle and magnetic moment with
Skeptical.
I'm trying to calculate the scattering cross section between a charged particle and a particle with a magnetic moment. I believe the... -
weirdoguy reacted to renormalize's post in the thread A Scattering cross section between charged particle and magnetic moment with Like.
What responses are you looking for that weren't covered in your previous thread...

weirdoguy reacted to Karmyogi01's post in the thread A Charge to mass ratio of a photon with Skeptical.
Photon is supposed to have a vanishingly small amount of charge and a vanishingly small amount of mass. However, I have been unable to...
