Hello everyone! I hope this is the correct spot for this question. Basically I was wondering who exactly can call themselves a scientist? I have several co-workers who have degrees in Environmental Science. We do not work in that field though. And during several debates - one in which they were arguing that Einstein hadn't "proved" anything and that it was all "theory". I was trying to explain to them that "theory" within science is not the same as in lay conversation. I explained that "theorys" explain facts. For example gravity is a fact. And the "theory of gravity" explains that fact. They responded to me - "Well, I'm a scientist. I have a degree in Environmental Science. And I'm telling you you're incorrect". I do not have a degree in any science so basically they feel as though my understanding of anything scientific is meaningless because I have no credentials. But back to my question. Does having a degree in Biology or Physics or Chemistry...etc....make you a scientist? Or does it simply say you have the credentials to get a job in that field of science? I'm not even sure that an Environmental Science degree is a "real" science degree actually. But I was hoping someone could shed some light on this for me!
