My discovery about mathematics

ζ(2)=π²/6=1+∑_i∈r1/2ⁱ (r⊂N)
r is a countable set. Existence of a countable set leads contradiction.
(Refer to "Defect of the formal algebra 1",3"" in this blog.) The standard
mathematics treating ζ(s) isn't consistent. Riemann hypothesis is nonsense.
Theory of the function √x is nonsense too.
