I undersand the term era but I don't know how to describe an era? Heisenberg's contribution was in 1927, what era was he living in?

20th century?

thats an era?

I counsel for fg

Hmm, century =/= era, at least not necessarily.

It seems that since Heisenberg was in the 20th century and that he was a theoretical physicist who was one of the key contributors to quantum mechanics, I would say this era would be called the "Birth of Modern Physics Era", since I think other theories like superstring / general relativity had more breakthroughs and 20th century is the modern age anyways.
