Can physics develop reasoning?
Robert G. Fuller, Robert Karplus, Anton E. Lawson · Physics Today · 1977
The life of every physicist is punctuated by events that lead him to discover that the way physicists see natural phenomena is different from the way nonphysicists see them. Certain patterns of reasoning appear to be more common among physicists than in other groups. These include: ▸ focussing on the important variables (such as the force that accelerates the apple, rather than the lump it makes on your head); ▸ propositional logic (“if heat were a liquid it would occupy space and a cannon barrel could only contain a limited amount of heat, but this is contrary to my observations, so…”), and ▸ proportional reasoning (for example, the restoring force of a spring increases linearly with its displacement from equilibrium).
