From: eestath on 2 Dec 2009 08:33 How can anyone can model Erratosthenes sieve?? first you exclude the prime numbers that have as factor 2 (1/2 of them) 1-1/2 then you exclude one third of them but half of them have factor 2 so you actually exclude 1/3 - 1/(2*3) then you exclude one fith of them but 1 in 2 has as its factor 2 and 1 in 3 have factor 3 so you exlude 1/5 - 1/(2*3*5) ..... please it seems it is basic common logic but i do not know if it is correct! So the series might look like 1+1/3+1/5+1/7+....-{1/2+1/(2*3)+1/(2*3*5)+...} or [1/2+1/3+1/5+1/7+....] - [1/(2*3)+1/(2*3*5)+1/(2*3*5*7)+....]

Your posts indicate that you're a better mathematician than Musatov, but significantly worse than James Harris.
