UP is like an invitation-only swimming pool on a blazing summer day. The moment you learn that you have received an invitation, you get so excited you’d want to jump straight in. And jump straight in you do, not minding the initial discouragement provided by long queues. Your body makes a cold splash into the surface and underneath you go. The water is cool. You smile in between segments of underwater respiration. You cherish the smooth feel the enveloping water gives. Wonderful.
And when your lungful of air is over, you break through the film of the surface once more, this time around attacking it from below. You look back and you realize that you’re already quite far from the shore. Must’ve been quite a dive eh? Then someone taps you and points forward. You see sharks. You try to turn back but then this person who pointed the sharks points to a sign saying “No swimming backwards”. Most likely, your parents are sitting near this sign as well, egging you on. You look at the sharks. You look at the sign. Repeat until satisfied. Repeat until you arrive at the conclusion that there is no other way but to get out of this pool in the proper state, id est, unmangled by the sharks and still breathing, still capable of continuing LIFE. This is where you realize that your initial excitement is nothing but the manifestation of hidden feelings of self-hatred and disgust stemming from the sociopathic urges you’ve had and repressed as a child. Not wonderful.
If my imagery allows, Physics is like another pool inside this UP-pool. Physics IS NOT a shark. It is another pool (inside this this pool, yes) which you are just so excited to toss yourself into at first glance but realize that you want to get out of this freaking hell alive as soon as possible. Erm no…Physics is an eddy current that seemed wonderful at first sight, further reinforcing the conclusion that your initial excitement is nothing but the manifestation of hidden feelings of self-hatred and disgust stemming from the sociopathic urges you’ve had and repressed as a child. Who else, aside from an atoning sociopath, would find the idea of tossing himself into an eddy current exciting? Dante shouldn’t have bothered describing the grotesque, the disgusting. He should’ve made them study Physics.
Despite that, Physics remains to be a wonderful foil for our intuition as well as for mathematical induction. Mathematical induction won’t always work in Physics. Mathematical induction is a poor way to conclude your experiments in Physics. Physics defies first impressions and base cases.
Physics is one of the things we should be thankful for. When was the last time you thanked gravity for rain fall? I thank friction for making rappelling possible, angular momentum for spinning kicks and electronics for computers. One of the good things inside this eddy current is that you get the right perspective to appreciate these simple gifts from natural laws.
What is the direction of the induced electric field in the reference frame of the rod shown in the figure at the right?
Nonetheless, with all the gratitude it makes me realize, I must admit that Physics is one subject that I’d like to get done with as soon as possible. And can someone please help me with the problem mentioned above? I do not need a solution just an answer. I have a guestbook ya’ know…
Or I have better idea:
Physicists I’m warning you (and mathematicians too). Ours is the final laugh.
Okay. Must make a sign now.
