Today we got a lesson in floating from Rick Crosslin, scientist in residence for MSD Wayne Township. He demonstrated a cartesian diver lesson from a “discrepant event” point of view.
Rene Descartes was a French Philosopher and Mathematician. He invented Coordinate Geometry (x y-axis, with +1 or -1).
He also invented an interesting toy that we can learn about the difference between liquids, gases and buoyancy.
He invented the Cartesian Diver, a toy that can be used to demonstrate the transmissibility of pressure! It’s an object that ordinarily floats and can be made to sink.
You can watch a longer version of the experiment.
