I have succeeded in getting my actual work down to thirty minutes a day. That leaves me eighteen hours for engineering.

Mathematics is the most exact science, and its conclusions are capable of absolute proof. But this is so only because mathematics does not attempt to draw absolute conclusions. All mathematical truths are relative, conditional. In E. T. Bell Men of Mathematics, New York: Simona and Schuster, 1937.

Marking dynamos for repair $10,000.00-2 hours labor $10.00; knowing where to mark $9,990.00.

Money is a stupid measure of achievement, but unfortunately it is the only universal measure we have.

Electricity is doing for the distribution of energy what the railroads have done for the distribution of materials.

Indeed, the most important part of engineering work-and also of other scientific work-is the determination of the method of attacking the problem, whatever it may be, whether an experimental investigation, or a theoretical calculation. ... It is by the choice of a suitable method of attack, that intricate problems are reduced to simple phenomena, and then easily solved.

No man really becomes a fool until he stops asking questions.
