Great Post

NO RATINGS
Cabe, I have admired your posts since you started for the broad range of topics discussed.  The volume you mentioned seems to be off, however, since it is not measured in mm, which is a linear unit.  Perhaps you meant milliliter (ml).  In any case, 600 atoms compared to the volume of 1 mole is tiny.  Since a mole (6.02 x 10^23) of gas takes 24.5 liters (l) at room temperature, one can figure out its volume using 1 l = 1000 cc and 1 cc = 10^12 micron^3.  If my calculation is correct, that volume is shockingly small, about 3 nanometer on a side.  Help, anyone?

This is indeed fascinating, Cabe. I wonder how this affects Big Bang Theory or String Theory.  It is always gratifying that scientists re-evaluate long held facts and adjust their hypotheses and theories. It adds even more credibility to science and mathematics. I think you have contributed a very important article.

I also wonder if the different latitude or altitude of the French researchers accounts for the different measurements. Does the rotation of the earth make a difference in the measurement? We know that it makes a difference in the rotation of storms.

In the words of our friend Spock...Fascinating! Thanks for a very interesting article,Cabe. I would think we will see more and more of this as technology advances our capibility to quanitfy measurements more accurately, although the methodology you described is mind-boggling. Nice to know that the effect is more noticeable at temp extremes but the ramifications for scientific study are clear. It is a little unsettling to think that constants as we have thought of them in the past may no longer be what we thought...
