Adventure Quote by Alfred North Whitehead
“In a living civilization there is always an element of unrest, for sensitiveness to ideas means curiosity, adventure, change. Civilized order survives on its merits and is transformed by its power of recognizing its imperfections.”

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)
