A living cell requires energy not only for all its functions, but also for the maintenance of its structure.

A discovery is said to be an accident meeting a prepared mind.

To regulate something always requires two opposing factors. You cannot regulate by a single factor. To give an example, the traffic in the streets could not be controlled by a green light or a red light alone. It needs a green light and a red light as well. The ratio between retine and promine determines whether there is any motion, any growth, or not. Two different inclinations have to be there in readiness to make the cells proliferate.

Discovery consists of looking at the same thing as everyone else and thinking something different.

The key to happiness is not to get more, but to enjoy what we have and to fill the empty frame of our lives instead of enlarging it.

Through the ages, man's main concern was life after death. Today, for the first time, we find we must ask questions about whether there will be life before death.

If structure does not tell us anything about function, it means that we have not looked at it correctly.
