Body Quote by Archimedes
“Any solid lighter than a fluid will, if placed in the fluid, be so far immersed that the weight of the solid will be equal to the weight of the fluid displaced. On floating bodies I, prop 5.”
About This Quote
Source Treat: On Floating Bodies, Archimedes, 3rd century BC
A solid less dense than a fluid will sink until the displaced fluid’s weight matches its own, achieving equilibrium.
In simple terms: Less dense objects float by displacing equal weight of fluid.
Key Takeaway
Float by matching displaced fluid weight.

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)
