DaveE replied to the thread High School Just a cool high school problem.Yes, so there is no unique answer for the purely vertical motion of the particle. It will hit the wheel at the same height it left... -
I don't understand why is infinity a problem. Sure, it is not intuitive and sometimes it complicates things. But to negate the infinity...

Like.
OK, so the test you are proposing is actually not a strong test of this. If you want to test for “apparatus history” you would want the... -
DaveE replied to the thread Graduate An electrolytic capacitor keeps charging by itself.Wait. Are you disrespecting the 100pW of charging power my previous data clearly demonstrated (at least once, anyway)? :wink: Yea...

DaveE reacted to Baluncore's post in the thread Graduate An electrolytic capacitor keeps charging by itself with Like.
Fifty years ago I remember reading about a device from fifty years before that. There can be rectifier action in every asymmetrically...

DaveE replied to the thread Graduate An electrolytic capacitor keeps charging by itself.Not precisely true. While larger in electrolytics, this is a well known effect in HV film and oil caps, which is why they are always...

DaveE replied to the thread Graduate An electrolytic capacitor keeps charging by itself.This is a DC effect. 60Hz energy harvesting would require a rectifier of some sort (like dissimilar metals?). Yet dielectric absorption...

A very thin metallic coating would possibly screen an Electric Field but would have little effect on any Magnetic Field so that some...

DaveE reacted to renormalize's post in the thread High School When light is polarized with itself with Like.
Yes, please do make a drawing since I don't understand your description. But do bear in mind that both the electric and magnetic field...

I was joking. (Poe's Law strikes again.) Yeah. It's not worth all my data and apps.
