It is indeed nature !!

 I have been advocating "Rational Number Series" for two or more years. I claimed that n/(n+1) as nature.

I have a point. In fact 3 points. First is the finite series which gives 2n/(2n+1). Second is (n^k)/((n+1)^k) as infinite series. Third is ((-1)^k)(n^k)/((n+1)^k) as infinite series. The second and third points give easily expressible numbers. See the screenshots below.

I was right in advocating and popularising n/(n+1).
