“Gravitation is not responsible for people falling in 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.”

“It's one thing to fall in love. It's another to feel someone else falling in love with you, and to feel a responsibility toward that love.”

“That was easy compared to this. It’s one thing to fall in love. It’s another to feelsomeone else falling in love with you, and to feel a responsibility toward that love.”

“ In one,Einstein is pictured over the words GRAVITY IS NOT RESPONSIBLE FOR FALLING IN LOVE.”

“Sorrow is implicit in love as gravitation is implicit in mass.”
