I earned my Ph.D. in philosophy, and one of my specializations was the logic and mathematics of game theory. I’ve also got a degree in drama, so I know about stories, characterizations, plot arcs, and the like. Lots of game designers can do one or the other: I’ve got the skills for both.

John Ambrose Fleming
After developing a primitive theory (1968) I therefore did not pursue this subject. However, the work was taken up by others and in 1974 the first experiments were done in the ISR.

Bruce Lipton
My parents encouraged us to commit to things, so if we wanted to learn an instrument, it was all the grades and all the theory.
Laura Mvula
We cannot even predict what kinds of emergent properties would appear when animals begin interacting as part of a brain-net. In theory, you could imagine that a combination of brains could provide solutions that individual brains cannot achieve by themselves.
