I think this vastly overstates Popper's influence. First, if you're trying to say that he's responsible for how science is done, I think that's flatly untrue. Popper's role is to describe and explain scientific practice, and understand how it is effective in producing understanding (assuming it does so--and most philosophers of science tend to agree).
If you mean that he's responsible for our understanding of science, that's debatable. Outside of philosophy, Popper is extraordinarily well known, and you can't avoid people speaking as if falsification is all there is to philosophy of science. Within philosophy, he is respected, but I don't think his particular views are particularly popular.
