This and tightening up the 2000 number to 1840 yields 1/3350, which should be within a percent or so of the truth. (Hydrogen makes a 10% difference for water, which is 72% of us, and about a 7% difference for the remaining 28%. The typical vertebrate organic molecule is mostly H,C,O,N with roughly as many H's as the combined number of C,O,N's.) -- ======================================================| God found the positive Vaughan Pratt pratt@cs.Stanford.EDU 415-494-2545 | integers, zero was ======================================================| there when He arrived.
