I find somethings in physics insanely provocative. Lets call them majins.
majin(n): A majin is that which gains value proportional to the thought invested in it.
Majins can make me drop game-pads in the middle of an assassination, unplug my earphones while listening to Cream and sometimes even walk out from a game of football.
Physics is full of majins. It is in fact Majin-Central!
Here's a majin: The principle of least action. Nature can transit from state A to state B in an infinite number of ways. But she chooses the path that minimizes her action. The action is a quantity which takes everything physically relevant into account, like mass,speed,etc.. It is also path dependent, which means that no two actions are the same because no two paths are the same. The path nature chooses to tread is that which minimizes her action. It is why throwing a ball makes it traverse a parabolic path. It is why Earth goes around the Sun. It is why light reflects off mirrors and refracts off lenses. It is why we see auroras near the poles and why fire happens.
Please note that when I say "why" something happens, it henceforth implies that I'm addressing the limit of our understanding through observation. So no more "why"s can follow. They are surely very interesting "why"s, but that isn't the subject of this post. Note: Making conclusions about the origins of your majin deprecates its value, often passing it on to a superior majin. This is often a good thing as it leads to exciting discoveries and more robust and versatile majins. But sometimes, to one's disappointment, this receiving majin might not be superior at all but simply an adhoc means to instate one absolute majin, ruler of all majins. Such a majin has not been verified with observation and if you think it does, you're a crazy person.
Here's another majin: The law of increasing entropy. Entropy is simply our net ignorance of the universe. Ignorance here refers to our lack of knowledge of the positions and momenta of the particles that constitute the universe." But we had no idea about the universe to begin with!", you ask? In physics, one often tends to take a word in existing vocabulary and modify it to suit the idea one is attempting to encapsulate. In this case, the word "universe" simply refers to something thermodynamically isolated meaning no information can escape or enter. Then we're still losing information? Yes! Because things get mixed up. Suppose you knew 2 numbers say 3 and 4. We then mix them up to get 7. There is no way we can recover those 2 numbers. The process of addition kills previous information. One can think of nature as constantly adding things up.
And if those majins weren't entertaining enough, try bringing them together. How is it that when we have such a powerful law like the principle of least action, we're confounded by the equally impressive law of increasing entropy? Is there some cosmic disharmony between these 2 majins? Perhaps one majin is more powerful than the other? Maybe both majins are plain wrong and there is a 3rd more superior less ambiguous majin somewhere? I'll leave this to your imajination.
