2nd Law of Thermodynamics, according to Atkin's Physical Chemistry, 8th Edition, chapter 3, page 78 states: No process is possible in which the sole result is the absorption of heat from a reservoir and its complete conversion to work. In other words, it's impossible to get to absolute 0 or it's impossible to get 100% work from heat. No where did I say we'd have to get to absolute 0 or turn all form of heat/energy into work. In addition, no where do we break entropy, it's still all around Mundus. Why do spells decay? entropy. Why do things rot? entropy. In a natural state, the universe becomes more random and low energy, and in order to bring something to higher energy, we need to put work in, or something like that. Things don't spontaneously happen out of no where. Magic allows skilled mages to manipulate magic (potential energy) to induce a spontaneous change in the environment. So no, we're not breaking second law.
As for first law, we're not turning nothing into something. Again, magic is used as a something to induce a change. Everything is conserved.
And no where is speed of light mentioned or anything of the sort. In fact, I've only been discussing thermodynamics, not the physical states, Laws, and Theories of Mundus, or anything else outside thermodynamics. At this point, I find that you have been quite rude, and trying to pass off as some higher thinking intellectual. All you have pretty much done is tell me I'm wrong, and not even really back it up. I have in previous threads discussed more in detail about this subject, and addressed the issues with conservation, and entropy. And if you want to know my "credentials" I'm a senior in college working on my chemistry/American Chemical Society degree. I've taken plenty of physics courses and physical chemistry courses, so don't tell me I don't know what I am talking about.
If you want to discuss why it's impossible to warp a creature from Oblivion instantaneously, be my guest, I'm not touching that can of worms. But if you truly want to take down my argument that magic follows thermodynamics, try something else other than saying "You're wrong, because I'm a physicist." Use some magic on us.
Awful defensive, aren't we? If you have to quote a textbook in a discussion with a person with a degree in a subject, I'm sorry, but you've failed. You also quoted the wrong law of thermodynamics--that's the third, not the second [unless perhaps the numbering is not canonical? I suppose it may be different in physics / other languages]. I'm not going to be "specific" because your idea of specific is apparently "fancy words" and really, to be specific I'd need to use, you know, math. Regardless, the point is, you've made literally dozens of implicit physical assumptions that you evidently have no idea you've made, which contradict the laws of physics. You don't need to state (or, evidently, know you've made) assumptions to have made them!
But, really, classically, "magic" is necessarily essentially a "maxwell's demon" type of setup. You can't reorganize things without changing entropy, and arbitrary reorganizations clearly violate the second law of thermodynamics. Exercise for the reader: calculate the transition probability between the states "air" and "air with fireball" (hint: it's
really small). Quantum mechanically / relativistically, you've made things much worse, which were mentioned in my previous comment.
If you search through the literature, you can occasionally find published examples of what laws of thermodynamics / the rest of physics things like this would violate, usually under the guise of teaching examples, but the real reason is obviously because it's fun to think about
. So if you want to find actual calculations that have no place on a forum showing exactly what details go into thinking about these kinds of things properly, please consult your favorite journal's database.
