Meredith Scheff has an interview with scientist/artist Alan Rorie. Alan was involved in the Steampunk Treehouse and the Dihemispheric Chronaether Agitator.
To me, science is largely about taking concrete aspects of the world and abstracting so that they can be communicated. I would spend weeks and months working on my thesis and the result would be some bit of data that only existed on the computer and in the mind of my peers. I realized that I needed to create real objects, things and stuff that existed in the world. Art, to me, is the flip side of science; it’s about taking the abstract ideas that exists in your mind and communicating them by instantiating them in the real world as solid objects.
So I taught myself how to weld.
