Why is this infinite product for pi not in any textbook? Is it not interesting for some reason?

PI = sqrt(2) * sqrt(3) * 2/sqrt(2^2-1) * 3/sqrt(3^2-1) * ... * p/sqrt(p^2-1) * ... 

for all prime numbers p

    Why should it be ?  What use does it have ?  I have no doubt that it is well-know to math nerds who have a special interest in prime numbers, but the rest of us can have a happy, fulfilled life without ever knowing of its existence.

      Also, there are an infinite number of primes. So, it is impossible to list them all.
