My education and work history are in the biological sciences (although I have admittedly recently made a career change).

To my mind, science (formerly known known as natural philosophy) is a subset of philosophy. However, it is a subset that has grown to dwarf the other subsets and is given separate, special attention. You do not learn much, if any, science in a philosophy degree because philosophy degrees now focus on philosophies that have not been spun off into separate degrees/fields.

Within the sciences, you do learn philosophy (or at least it factored highly in my undergraduate degree), but it's not about Aristotle or Nietzsche. It's about the assumptions and logic underpinning the scientific method, statistical analysis, etc.

My introductory classes, at least, covered a number of arguments and assumptions that (to my ear) are very much questions of philosophy. For example, scientific inquiry is dependent on the assumption that the laws of the universe are consistent across time, meaning that experiments performed now can nonetheless offer insight into past and future phenomena.
