again, life is good

life is good

that pencil cap i found last night turned out to be a sign of luck, indeed
who needs a four-leaf clover? hah! take that, you stupid leprechaun

physics final was by far the best final i've had this quarter
or, to put it differently: the only final i have an idea on what i'm doing
some problems were boring and i have to admit i did fall asleep for a minute or two once or twice, or thrice
but some other ones actually got me thinking and although hard, was much better than the boring ones
the pleasure doubles--no, triples, or even quadruples--when you managed to figure out a way to solve the hard ones =)

i need to pay more attention to some more variety of periodic functions, SUCH AS COSINE
when they tell you it's a periodic function with angle = (kz-wt) but you get a maximum when z=t=0
know immediately it's a COSINE
i did notice there's something wrong with using a SINE function but that's what my cheat sheet said so i just followed it
oh well
at least i know how to derive the poynting vector function =)
and at least i got a full working knowledge of diffraction and interference effect =D
either way, the final is over ^^

I ALREADY GAVE IT MY BEST, I HAVE NO REGRETS AT ALL

HAHAHAHA
