You could say that jews had economic power in europe, even in medieval times. Jewish people lived seperatly from the gentile population so social and political power would not matter. If jewish people wanted to they could have discovered the scientific discoveries made by the white gentile people of europe long before those gentiles had made them. But jews did not care and had no understanding of what science is, they had to wait for the white gentile people to define it even though they had alot of time to think about it over the years.
How much do you think it takes to make scientific discoveries? All you need is a chemistry set, alot of jews were alchemist in medieval times but those jews made no fundamental discoveries in chemistry. Alot of jews throughout their history in europe were doctors but there were no medical revolutions eminating from these jewish doctors.
The reason why I say this is because if you listen to jews talk about the history of science they usually imply with everything they say that jews are the reason why science exists and that is completely incorrect. If it wasn't for the white gentile people who defined what science is there would have been no scientific revolution in europe even with the jews there.
