I could watch and listen to brian my love for the rest of my days.... "energy is eternal" *sigh*

[ProfessorBorax]

Brilliant, beautifully simple, good job!

[xwhEdward]

energy is eternal. The evolution of the universe is just a story of the transformation of the energy. Isn't that interesting?

Then he discovers the 2nd law and some inevitable philosophical pessimism kicks in: energy while being eternal degrades it's quality or capability of producing work.

Fun fact: There's more bacteria in your gut than the number of people who have ever lived on Earth.

How do we know that the 1st law of thermodynamics is actually true?  I mean, do we really have a means of falsifying it?  Or actually proving it?   It obtains for isolated systems, sure -- but that's about it.  To make a metaphysical statement out of that strikes me as a bit premature, a bit silly.

I really don't care much for this guy... I'd rather another host.
