Good for you. I was only trying to convey that I really did know what an exponential function was. LOL. Incidentally, I decided after the BS that I wasn't that interested in particle physics, which was all the rage in the 70's, so I went in to engineering (spacecraft and computer systems) and have been working there ever since. I didn't go for advanced degrees, so you've got me there. :-)
Have a great day.
