comment How can I stand on the ground? EM or/and Pauli?
Actually, I think Ron Maimon is right.

comment How much effect does the Bernoulli effect have on lift?
@MikeDunlavey I stumbled across Denker's website about seven or eight years ago and it made a huge impression on me.

@mike Thanks Mike. I'm not used to people agreeing with me.

It is equally true that all the lift depends on the change in airflow direction. You have to calculate one or the other but not both.

comment Can light be canceled by merging with an inverted wave?
@EduardoGuerras Acutally I did downvote and then regretted it. I think it's more important to leave the upvotes as evidence of the quality of voting that goes on here.

comment Radiated power and energy density for a black-body
I may have been hasty in my explanation when I said you get a "factor of 2" on the average speed of energy perpendicular to the surface. I've redone my calculations carefully and I seem to be getting an overall energy density of (3*pi/2)(power/c). I'll try to post the analysis as an edit to my answer.

comment Is there any thing other than time that “triggers” a radioactive atom to decay?
Thanks, Helder. It's too bad that this website doesn't promote more discussion. I feel like after the first day or two, the topics just disappear from the radar.

comment How does scattering work?
I find it disturbing that people are upvoting this answer. Surely the scattering of sunlight by molecules in the air has nothing to do with coulomb potentials. And there is no attempt to address the question of why the sky is blue.

comment Tidal force on far side
Yes, the electrostatic case is the same as gravity. The immobility condition however is problematic. An important aspect of the tidal system is that the earth and moon are in free-fall about each other. That's why the average field has no visible effect, and only the distortional component is at work. Also, I question Nick's asymmetry. In my analysis, the quadrupole force is symmetric.

comment Angular Momentum of Diatomic Molecules
Yes, that's the same bond length I'm using; I've expressed it as 2.2 Bohr radii, using a value of 53 picometers.
