The more thoroughly I conduct scientific research, the more I believe that science excludes atheism.

I need scarcely say that the beginning and maintenance of life on earth is absolutely and infinitely beyond the range of all sound speculation in dynamical science. The only contribution of dynamics to theoretical biology is absolute negation of automatic commencement or automatic maintenance of life.

In science there is only physics; all the rest is stamp collecting.

Mathematics is the only true metaphysics.

I believe that the more thoroughly science is studied, the further does it take us from anything comparable to atheism.

Although mechanical energy is indestructible, there is a universal tendency to its dissipation, which produces throughout the system a gradual augmentation and diffusion of heat, cessation of motion and exhaustion of the potential energy of the material Universe

There is nothing new to be discovered in physics now. All that remains is more and more precise measurement.
