comment Intereference rings by light transmission?
Wow! Great charting for an answer. I imagine Buttonwood could put a drop of optical fluid or water between the cells? A scrap of lens paper between them to make the gap wider and a wedge would at least move the peaks of the ripple closer?

comment I'm reading this in a senior year physics text book, need to know if this is true, and if so then how? :
I suspect the text has defined a 'complete magnet' as having both a north and a south pole, and that no matter how the magnet is broken down, there will never be just north or just south poles.

Found this: larryniven.net/physics.shtml. No ball of air, though.

comment Could a planet sized bubble of breatheable atmostphere exist?
Science Fiction author Larry Niven has a story, 'Smoke Ring' I think it was, that had a ring of atmosphere orbiting a neutron star or some such thing. But that would be a slightly different question: 'Is Larry Niven's 'Smoke Ring' possible?' I guess that question would be.

comment Path of an electron through an electric circuit
@SamamaFahim I am trying to make a cartoon model of the battery for a nephew, and this is a good question. In my cartoon, the electrons in the battery must hop a ride on 'ion cars' to get to the other side. I have them filling empty box-cars when they arrive at their terminal when the battery is discharging, and the filled box-cars (ions) pumped to the other side when the battery is charged. This may be way off base. Any help from the experts?

comment On the optics of high-resolution surveillance drones
@user20359, probably not. You need to consider the aperture (sp?) too. See Airy Disk:en.wikipedia.org/wiki/Airy_disk
