With twin primes a simple approach rips the prime distribution out of the equation. that is not even a sentance. Since the result equals prediction correlation is 1. the word "correlatio... 14 Mar 2010 14:18

about maths: strictly speaking, off topic, but justified.
Apologies in advance for posting somewhat off topic, but I would like to address this questions to scientists only as I'm not interested in the view of Phil-Sci students in this particular instance. Its a fairly simple one. I'm studying physics and am okay with the scientific process - using maths to describe ... 30 Mar 2010 09:25

Space flow and energy flow
Energy flow increase raises energy. Space flow increase lowers energy in stronger gravity when falling stops. Gamma for energy gives total energy for energy that flows. Gamma for space flow lowers mass for objects in slower aether gamma time. Space flow pushes matter flow into slower flow of aether over energy... 13 Mar 2010 23:05

You quite sure you aint one of those rocket scientist fellas?
Just wondering what that was. Is it some kind of stereotype used to derogate people who know more than others? --------------------------- It is interesting that Thales has both stories told about his great practical skills and also about him being an unworldly dreamer. Aristotle, for example, relates a story ... 14 Mar 2010 21:00
