James Clerk Maxwell

I have been trying to make a mechanical model of the electromagnetic field, but I find it very difficult.

The value of a scientific theory is its power of prediction.

I have a great desire to know what is going on in the world of science.

The most important thing in science is to ask the right questions.

I have been thinking about the nature of color, and I believe that it is a physiological phenomenon.

The great aim of science is to find out the laws of nature.

I have been trying to make a model of Saturn's rings, and I believe that they are made of small particles.

The only way to avoid error is to have no ideas.

The true logic of this world is the calculus of probabilities.

In the study of nature, we must not only observe, but also measure.

The velocity of the electromagnetic wave is equal to the velocity of light.

We have thus a physical theory of light, which is free from the hypothesis of an elastic solid ether.

The most important results of the scientific work of the past century have been the establishment of the laws of conservation of energy and of the transformation of energy.

The history of science shows that the progress of science is often due to the discovery of new methods of investigation.

The scientific method consists in observing, experimenting, and reasoning.

The aim of science is to understand the world in which we live.

The greatest discoveries of science have been made by men who have been guided by their imagination.

The true value of a scientific theory is not in its ability to explain known facts, but in its power to predict new ones.

The most profound discoveries in science are often the simplest.

The progress of science depends on the free exchange of ideas.
