I'm giving a presentation to a group next week made up of mathematicians, physicists and mechanical engineers. My talk is going to be related to my work so it's going to be very biology based. I want to start the talk pointing out that life science and the physical sciences are very different in their cultures and I thought it would be fun to have a slide with terms both use but completely differently. The point of this is to lead on to saying that if at any point I'm using a term that you know but don't see how it fits then feel free to ask. Examples I have so far are vector, plasma and differentiate, can anyone think of any others?
