Neil Armstrong once portrayed himself as follows [1, 2]:
I am, and ever will be, a white-socks, pocket-protector, nerdy engineer—born under the second law of thermodynamics, steeped in the steam tables, in love with free-body diagrams, transformed by Laplace, and propelled by compressible flow. As an engineer, I take a substantial amount of pride in the accomplishments of my profession.
Neil “slipped the surly bonds of earth” and “trod the high untrespassed sanctity of space” . He died yesterday [4, 5].
