Pierre Fermat made a hypothesis in the mid-17th century that fundamentally revolutionized science. He argued that the changing path of light when it passes from one medium to another could be understood as light taking that specific path that would bring it most quickly from its origin to its destination. In the modern form of least action, this is the most universal principle of physics. How did Fermat make his breakthrough? And why is "purpose" a scientifically useful concept? Join us for an exploration of one of the key thinkers of Lyndon LaRouche's "narrow path" of discovery!
