The chemist in America has in general been content with what I have called a loafer electron theory. He has imagined the electrons sitting around on dry goods boxes at every corner [viz. the cubic atom], ready to shake hands with, or hold on to similar loafer electrons in other atoms.

From that night on, the electron-up to that time largely the plaything of the scientist-had clearly entered the field as a potent agent in the supplying of man's commercial and industrial needs... The electronic amplifier tube now underlies the whole art of communications, and this in turn is at least in part what has made possible its application to a dozen other arts. It was a great day for both science and industry when they became wedded through the development of the electronic amplifier tube.

Science walks forward on two feet, namely theory and experiment.

Cultivate the habit of attention and try to gain opportunities to hear wise men and women talk. Indifference and inattention are the two most dangerous monsters that you ever meet. Interest and attention will insure to you an education.
