Can't do this one in my head...As much as it seems inconceiveable, I dod not
memorize the Log tables... but I could take a shot at it......Is it cheating
if I use a set of Trig tables I got from my Father when HE went to MIT in
1939?

The Log is to the base of 2 or 10?

Frank Filippone.. getting psyched to do this with the least amount of
electrons destroyed......

The formula is

log(lux/2.5)/log(2)=EV
