I know the feeling, so I'm taking the edx Thermodynamics MOOC to try to learn more about the subject.
Something I learned in the first week: the assumptions of Thermodynamics are astonishingly limited. According to Professor Gaitonde, the science of Thermodynamics is macroscopic (so it doesn't say anything about microscopic phenomena). The assumptions are:
1) No quantum effects
2) No relativistic effects
3) No scale effects.
So any limits derived by Thermodynamics only apply to a small range of phenomena, when you consider the universe. Dark Energy, Dark Matter, Quantum Physics, and Computer Science (since scale effects are very important) are not limited by the assumptions Thermodynamics makes. The laws of thermodynamics, based on these assumptions, don't apply as broadly as people commonly assert.
