“As the grand discordant harmony of the celestial bodies may be explained by the simple principles of gravity and impulse, so also in that more wonderful and complicated microcosm, the heart of man, all the phenomena of morals are perhaps resolvable into one single principle, the pursuit of apparent good; for although customs universally vary, yet man in all climates and countries is essentially the same.”

I've also done some gravity tests with ZERO-G [a charter-flight service in Arlington, Va., that uses modified Boeing 727s to simulate weightlessness], which went great.” quote by Richard Branson](https://sms4smile.com/quotes/img-quotes/aa1/richard-branson-256_adventure_i-ve-used-the-phoenix-centrifuge-to-repl_903.jpg)
