To my reading this article saye that claims of lead poisoning were made but seem very unlikely. Pleae represent claims more carefully....or am I missing something?

Have you a reference for this? It seems unlikely to me, but data might be convincing. Also a red herring in this context.

Please read. I said torques not well defined. torques need to reference an axis.

"Torque on each leg" is not well well defined. I think you are confused......if these wires are rigid, force on each will resist the applied force. These forces will all lie in the plane of the paper. Note also that center of the "loop' is moving as well.

That's very impressive. I look forward to reading it. Congratulations.

I have a certain fondness for "The Big Bang Theory" television show and have been pleased not to have detected horrible gaffs when they do expound upon things in the Physics realm. Admittedly this is not very often which also inures to the benefit of show: there is no gratuitous "gee whiz"...

And in fact the solution for a "generic" two-slitted plane wave is easy to write down (at Fraunhoffer limit) and so why is this well-intentioned human wasting so much energy retpatedly (and obsessively) just waving her hands at it?? The actual answer, although of large historical...

Look at some limit cases.....what if atmospheric pressure is nil......does your equation for P1 seem correct? What if it gets bigger than 0?

This is, without doubt, the Nerdiest (Nerdliest?) effort ever produced. Congratulations to all involved!

Although I slighted @Gavran by not mentioning his attempt, I don't think anyone had called out Ptolemy's Theorem by name. How often do you get to cite Ptolemy directly?? Who wouldn't want to add that in.... lotsa fun....and pedagogically an impressive theorem IMHO.

Yes indeed. Through laziness I did not really look at the attempt.......bad form on my part (apologies!)

Please feel free. I have had an exhausting week and seem disinclined to do anything (feeling each of my 73 yrs I guess.....ah, well. I wish LaTeX was not such a chore for me)

There is also a lovely theorem by Ptolemy that deals with cyclic quadrilaterals. I think that will work......not an intuitive result! Will write it up if time/energy permits. https://en.wikipedia.org/wiki/Ptolemy%27s_theorem

I think it unlikely that any known hull material could have contained the colossal ego of Stockton Rush, a walking rebuttal to the aphorism that a man's reach should always exceed his grasp.

The neutral current path offers a very low resistance path for the current, and so most of the power follows this path. The local neutral ground is important to ensure that no large potential differences can accrue over time (i.e. the V=0 point remains good). The electrical resistance of...
