Moshé Feldenkrais as a Physicist

Feldenkrais studied at the Sorbonne and earned a degree in Applied Physics. He uses physics terms in a playful but ultimately precise way — and 'differentiation' is a good example.

Remember calculus? Differentiation in calculus is about finding the rate of change — breaking a continuous process into infinitesimally small steps to understand how it is changing at any given moment. That's not a crazy analogy for what Feldenkrais lessons do: they build from variation to variation, each one isolating a slightly different slice of a movement to understand how it's organized and to put you in choice about what you want to do with it.
