A favorite author (now-a-days) writes some 1/2 century ago, in his text (2nd edition, 1970) what could be considered a foundational basis to our existence. He writes, italics all mine:
"We now know" ... [ written on page 14 of his 2nd chapter titled A mathematical description of the universe - imagine that! ] ... "that any object, however complex" ... [ object defined p. 784 Webster = something that is or capable of being seen, touched, or otherwise sensed ] ... "can be visualized as a sufficiently complicated structure" ... (whew) ... "built out of atoms," ... "and that the atom itself is a structure composed" ... (almost there) ... "of three fundamental particles, electrons, protons, and neutrons."
What a deal! Written some 57 years ago. What do we now know?

The image is to show a carbon atom with 6 protons and 6 neutrons. The electrons circle about the nucleus suggesting their probable pattern of movement. Anyone for a spin?Dull, C.E., Metcalfe, H.C., Williams, J.E., Modern Physics, Holt, Rinehart and Winston, N.Y. 1964.
