As a man who has devoted his whole life to the most clear headed science, to the study of matter, I can tell you as a result of my research about atoms this much: There is no matter as such. All matter originates and exists only by virtue of a force which brings the particle of an atom to vibration and holds this most minute solar system of the atom together. We must assume behind this force the existence of a conscious and intelligent mind. This mind is the matrix of all matter.

-Max Karl Ernst Ludwig Planck

One of the most important German physicists of the late 19th and early 20th century, winning the Nobel Prize in Physics in 1918; he is considered to be the inventor of quantum theory.
