#Chemistry

"You either have chemistry or you don't, but a lot of what attracts me is a guy's mind and humor and talent. I need to get to know all those things before I fall for someone."

"Sometimes the best and worst times of your life can coincide. It is a talent of the soul to discover the joy in pain—-thinking of moments you long for, and knowing you’ll never have them again. The beautiful ghosts of our past haunt us, and yet we still can’t decide if the pain they caused us out weighs the tender moments when they touched our soul. This is the irony of love."

"Those distinct substances, which concretes generally either afford, or are made up of, may, without very much inconvenience, be called the elements or principles of them."

"Mathematics is the cheapest science. Unlike physics or chemistry, it does not require any expensive equipment. All one needs for mathematics is a pencil and paper."

"Thus, for those of us who make only a brief study of chemistry, the benefits to be expected are of an indirect nature. Increased capacity for enjoyment, a livelier interest in the world in which we live, a more intelligent attitude toward the great questions of the day--these are the by-products of a well-balanced education, including chemistry in its proper relation to other studies."

"Chemistry can be a good and bad thing. Chemistry is good when you make love with it. Chemistry is bad when you make crack with it."

"I try to show the public that chemistry, biology, physics, astrophysics is life. It is not some separate subject that you have to be pulled into a corner to be taught about."

"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?"

"The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed."

"There has to be chemistry in a duet, but if you go beyond the point of friendship and attraction, you lose something."
