Yep. I corrected my typo in a later post. It's amazing how one can type the word "electron" but be thinking "neutron".

Greene is one of the sharper knives in the drawer. His explanation of the observed flatness of the universe is mind-expanding.

Yes, I often get terms confused myself, there are so many in physics. Then I often get ahead of myself : brain thinks much faster than one can write. Ok then, have you got an answer to t=dKE? Or, can you demonstrate a time event that is not a kinetic energy event? $1000 quick cash if you can(small, unmarked bills in a brown paper bag, out in the alley, furtive glances all around...). W=P

I typed "nucleotides" when thinking "neutrons" once. Then there was the time I typed "Romania is landlocked."
