“No, this trick won't work... How on earth are you ever going to explain in terms of chemistry and physics so important a biological phenomenon as first love? ”

“Gravitation cannot be held responsible for people falling in love. How on earth can you explain in terms of chemistry and physics so important a biological phenomenon as first love? Put your hand on a stove for a minute and it seems like an hour. Sit with that special girl for an hour and it seems like a minute. That's relativity.”

“If it squirms, it's biology. If it stinks, it's chemistry. If it doesn't work, it's physics. And if you can't understand it, it's mathamatics.”

“If it dies, it's biology; if it blows up, it's chemistry; if it doesn't work, it's physics!" As quoted from grafitti on a bathroom wall.”

“To be born again,' sang Gibreal Farishta tumbling from the heaveans, 'first you have to die. Ho ji! Ho ji! To land upon the bosomy earth, first one needs to fly Tat-taa! Takatun! How to ever smile again, if first you won't cry? How to win the darling's love mister, without a sigh?”

“...how much needless despair has been caused by a series of biological mismatches, a misalignment of the hormones and pheromones? Resulting in the fact that the one you love so passionately won't or can't love you. As a species we're pathetic that way: imperfectly monogamous.”
