In modern society where most people live in cities and where both needs and wishes are absolved through the same remote agency - money - the distinction between wishes and needs has altogether vanished.

This society cannot go forward the way we have been going forward where the gap between the rich and the poor keeps growing. It's not politically viable it's not morally right it's just not going to happen.

Class is not a fixed designation in this country. We are an upwardly mobile society with a lot of movement between income groups.

Similarly thought is a system. That system not only includes thought and feelings but it includes the state of the body it includes the whole of society - as thought is passing back and forth between people in a process by which thought evolved from ancient times.

We sometimes laugh from ear to ear but it would be impossible for a smile to be wider than the distance between our eyes.

Laughter is day and sobriety is night a smile is the twilight that hovers gently between both more bewitching than either.

All the mathematical sciences are founded on relations between physical laws and laws of numbers so that the aim of exact science is to reduce the problems of nature to the determination of quantities by operations with numbers.

Science is based on the possibility of objectivity on the possibility of different people checking out for themselves the observations made by others. Without that possibility there is no empirical principle capable of deciding between different arguments and theories.

If you publish a scientific paper it is very hard to start a nationwide debate about something. If you do this in a movie you can start a debate. We like to create a bridge between those two worlds - film and science.

The further a mathematical theory is developed the more harmoniously and uniformly does its construction proceed and unsuspected relations are disclosed between hitherto separated branches of the science.
