berkeman reacted to A.T.'s post in the thread Undergrad Extreme Negative Polarization (peer reviewed Astrophysical Journal) with
Like.
It's explained in the paper you linked: Polarized sunglasses do not generate polarization by scattering, so you cannot apply the above... -
berkeman replied to the thread Undergrad Can nested solenoids trap particles?.Sorry, that does not help; it is not the sketch that I asked for. What are you trying to accomplish?

berkeman replied to the thread Undergrad Can nested solenoids trap particles?.Huh, interesting. I need to do more reading, but their system of direct energy extraction is interesting. I wonder how fast they are...

Informative.
Oh yes. Helion energy is banking on it. They started construction on a power plant in July, 2025. Whether they will succeed is... -
Welcome to Physics Forums @Adina C, I'm a bit confused by the question and a bit confused by the input file. The number of histories...

berkeman reacted to Steve4Physics's post in the thread Questions about a parallel plate capacitor apparatus for lab experiments with Like.
@DDesulgon, you might find the following link useful - it describes an experiment with the sort of capacitor similar to the one you...

berkeman reacted to renormalize's post in the thread Undergrad Spectrometer of James Webb Space Telescope with Like.
Alas no, my familiarity with the literature of comets is too meager to offer suggestions. Yes, exactly as is explained in the last...

berkeman reacted to phyzguy's post in the thread Undergrad Can nested solenoids trap particles? with Informative.
I think what you are talking about is similar to the field reversed configuration, which is being studied as a possible path to...

berkeman reacted to Demystifier's post in the thread Undergrad Why is thermal energy treated differently than other kinds of energy? with Like.
In principle, we could completely ignore statistical mechanics and thermal energy, and explain everything as you would like, in terms of...
