Henry: God gave us thermodynamics but not kinetics!
Me: What do you mean?
Henry: I mean -- we can measure differences between where we are and where we've been, and also between where we are and where we'll be. Those things never change -- they're tabulated.
Me: But you're talking about free energy differences and chemistry....
Henry: Yes, of course...that too.
Henry: How things get from here to there is what we fight and argue about...it's the kinetics!
