Thanks. My personal theory (take it for what it's worth) is that at least two major factors in the stagnation: The first technical. Scientific advancement seems to be dependent upon two technical factors: our tools of observation (which includes mathematical tools like statistics which help us to "see" patterns in data) and the ability to produce energy. We need better tools for "seeing" and more abundant energy to make further advancements. The second factor is social. Scientific innovation requires creativity, but scientific institutions are increasingly hostile to the needs of creativity.
