I'm not sure this question makes sense your asking what knowledge and understanding of scientific principles have been significant but knowledge and understanding is on an individual basis of comprehension of a certain subject or area of science. There have been individual people who have significantly helped in certain fields of science like Stephen Hawking specialising in theoretical cosmology and quantum gravity, specifically furthering our understanding of Black Holes.
Unfortunately I cannot directly answer your question due to it being too vague but I hope this helps.
