Nick Lucid on mass and energy

I’m a bit busy today, but thought I’d leave you with this Science Asylum video on the difference between mass and energy.  (Hint: there isn’t any.)

 

Nick Lucid on entropy

Entropy is something I have to re-read about from time to time.  It tends not to stick in my head for some reason.  Nick, in the way only he can, suggests a possible way of thinking about it.

I’m still not entirely sure the statistical description answers the questions he asked at the beginning though.  Personally, I tend to think of entropy as burnt out stuff, such as dead stars or ashes.
