I love reading Asimov's monologues on sciences, as well as his fiction. Some of the books I have are crumbling with age, and I keep piecing them together. That's devotion, chum.
I'm confused, though, about the laws of Thermodynamics. Maybe someone can easily answer it here, if they'd be willing.
As I understand it, the First law says that energy can change form, but that there's a fixed amount in the cosmos, and that that is unchangeable.
How, then, can that comport with the concept of entropy? Isn't entropy involved with the Second Law, which tells us that no use of energy can ever be 100% efficient, that some energy will always be lost and can never be recovered?
Don't these two things conflict? How can the universe "wind down" (entropy) when it has a fixed amount of energy that is static and unchangeable?
Probably a first year college Physics major could answer that one in a coma. I'd ask Mr. A. if he were still alive and was online answering basic and inane questions like mine.
I'm not a student, though I'd like to be. But I'd be too sexy and old for it; the students wouldn't be able to resist me and would flunk because they couldn't pay attention in class. I wouldn't want to jeopardize the next generation's intellectual achievements.
Thanks,
