Feynman's Building Blocks of Thermodynamics - with Andrea Sella
How Richard Feynman's classic analogy of building blocks explains the conservation of energy. Professor Andrea Sella recalls Feynman's illustration of the first law of thermodynamics with...
========== The first law of thermodynamics, the one which
says that the total amount of energy is fixed, that energy can't be created or destroyed, Sometimes people say that that law states
that there's no such thing as a free lunch. That energy is a little bit like money in
a bank account. You can always account for it, that there
is a ledger where you can add or subtract and you can
keep track of the energy. There's a beautiful example of this from Richard
Feynman where he tries to explain how energy works. And he says it's a little bit like a child
that has a set of twenty eight wooden blocks that he uses as toys. And every day his mum comes in and she counts
the blocks when she puts them back into their box And every day she finds that there's 2...
