Majin

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.

Burning the Midnight Oil

You're either a morning person or an owl. The famous lark and owl dichotomy estimates when we are at our most productive. At some in your life, you will cross the line and step into the shoes of your alter-ego. The lark will inevitably oversleep for nights in a row- upsetting the circadian rhythm- and thus cross over into owl territory. Usually this happens at University, when you're up partying too hard with the roommates, watching one Matrix movie after another or just marathon watching seasons of 30 Rock.
With the advent of the personal computer (or Mac, for you Apple fans) and ultrafast Internet, burning the midnight oil has changed completely. No more are you stuck at the library's reference section, afraid to take a pee break lest someone up and offs with your textbook on Biochemistry. No more will the librarian bother you to put away your iPod, even though it isn't audible to anyone but you. And yes, there is so much information out there that studying becomes no longer a headache, but sometimes a pleasure.

During the day, I do little of educational worth. I do chores around the house, clean and dust up and do quick runs to the bank, check my email and watch reruns of The Big Bang Theory on television.
Then the government mandated 2 hour blackout occurs, during which there is plenty of sunshine but no electricity to escape the heat of the late afternoon. These two hours, I use to read up on my novels (Stieg Larsson's trilogy and a primer on the American Political system) and also on my Japanese. After the power returns, the next couple of hours are spent on coffee, TV and the loyal iPod. Then as evening arrives, the textbooks are opened up and the journals are opened and I read up on immunology. Each time I brush up on the basics, I learn something new and the prospect of being a tad more knowledgeable than ten minutes back is a real thrill. I split the week between boning up on basics and looking for PhD's. And more often than once, I have a question or am doubtful on the definition of a certain word. Open up Google and hey presto, done!
And Youtube is a rich treasure trove of information on biology and immunology. There are many lectures and demonstration videos covering everything from immunology to basics like 2D electrophoresis! Never again will you be building up on weak foundations or faulty assumptions.

The day ends for me at 2 am when my brain finally stops listening to me and shuts down. I plop down and before I know it it's late morning again. There are a few disadvantages to being an owl: You can't go for a morning walk; can't see the old uncles "jogging" in their shorts; you miss the extra Vitamin D that you get only at sunrise, but hey- you wake up just late enough to justify brushing your teeth and avoid being judged by the neighbours. Hey, atleast you're getting some work done, yeah?

Are you an owl or a lark? Hope to hear in the comments.
