Given a subset A of the primes and a positive integer N, we define the relative density delta (N,A) of the set of elements of A less than N as the quotient between the number of elements af A up to N and the number of primes up to N. Ben Green proved that if N is large enough and if the relative density delta (N,A) is large ...

... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...
