I think I've always had a certain amount of skepticism of this whole 'shut up and smile' theory. I haven't ever swallowed that pill so easily although I tried.

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.

The theory of undirected evolution is already dead but the work of science continues.

Science is not about control. It is about cultivating a perpetual condition of wonder in the face of something that forever grows one step richer and subtler than our latest theory about it. It is about reverence not mastery.

The birth of science as we know it arguably began with Isaac Newton's formulation of the laws of gravitation and motion. It is no exaggeration to say that physics was reborn in the early 20th-century with the twin revolutions of quantum mechanics and the theory of relativity.

Don't confuse hypothesis and theory. The former is a possible explanation the latter the correct one. The establishment of theory is the very purpose of science.

The 'science' for which the United States is respected has nothing to do with the unscientific and baseless theory of evolution.

I hesitate to predict whether this theory is true. But if the general opinion of Mankind is optimistic then we're in for a period of extreme popularity for science fiction.

If you start any large theory such as quantum mechanics plate tectonics evolution it takes about 40 years for mainstream science to come around. Gaia has been going for only 30 years or so.

Einstein was searching for String Theory. It not only reconciles General Relativity to Quantum Mechanics but it reconciles Science and the Bible as well.

Time travel used to be thought of as just science fiction but Einstein's general theory of relativity allows for the possibility that we could warp space-time so much that you could go off in a rocket and return before you set out.

Scientific theory is a contrived foothold in the chaos of living phenomena.

Science is organized common sense where many a beautiful theory was killed by an ugly fact.

Your theory is crazy but it's not crazy enough to be true.

My object will be first to show by what connections the history of the fossil bones of land animals is linked to the theory of the earth and why they have a particular importance in this respect.

Internationalism is a community theory of society which is founded on economic spiritual and biological facts. It maintains that respect for a healthy development of human society and of world civilization requires that mankind be organized internationally.

My theory is if you have a religion it's a good one. Because some people don't have any at all.
