Zeev, good of you to share and you did it very good. Question: If you
could go back to young age, imagine the contribution you could have
made to advance technology if you became a physic & chemistry teacher
and with your good skills to teach. I mean do the math...rather than
produce 1 world class scientist of Zeev Hed, Zeev 'held' back and
motivated at least 3 or 5 at the highschool level to enter the sciences
and produce as Zeev has done. See, you could of indirectly created
three times as much by being that special highschool teacher.
But I shouldn't complain, one Zeev is better than none. I wonder what
those 3 or 5 gifted kids did, probably butcher baker & candle stick maker.
Back to the copper thing. In the future when a room temperature ceramic
is finally created that electricity can flow thru like copper wire, you mentioned
that there will be a weight reduction if it patterns along the same characterists
as current high temperature ones. A question along the lines of what
weights more, a pound of gold or a pound of feathers, using todays stuff,
the ceramic roll of wire will weigh as you said about 1/5 that of copper,
but will the volumn or say the diameter of ceramic wire be the same as
the copper. I think if you sit on a pound of feathers it might have less volumn
than a pound of gold. Need a tank of water to find out, assuming that the
feathers and stalks will not absorbe water, and if did then need a liquid
like mercury maybe if its molucules are much bigger.
<< these [high temperature] superconductors need to be cooled to
liquid nitrogen temperatures.>>
See what a good teacher you are Zeev, you give us interesting information,
and included in the "answer" is a question.
<<liquid nitrogen temperature>> = ?
and then...what was the prior coolent used, and its temperature
....and then scales of F for USA and C for Canada and A for Zeev.
yes Zeev gets an A
Thanks
