The concrete shell of this stove would surely crack if its strength were not reinforced with steel rod, wire fabric, or barbed wire. The latter is our choice. We laid continuous strands of barbed wire between the rows of slip form masonry. The thermal expansion rate of concrete is the same as steel up to a temperature comparable to boiling water... Beyond that, steel expands at a faster rate than concrete. At a temperature of about 500 degrees F., the bond between the concrete and steel is destroyed... The type of aggregate in the mix is primarily responsible for this kind of failure.

The method of successive approximations is often applied to proving existence of solutions to various classes of functional equations; moreover, the proof of convergence of these approximations leans on the fact that the equation under study may be majorised by another equation of a simple kind. Similar proofs may be encountered in the theory of infinitely many simultaneous linear equations and in the theory of integral and differential equations. Consideration of semiordered spaces and operations between them enables us to easily develop a complete theory of such functional equations in abstract form.

We may lay it down as an incontestible axiom, that, in all the operations of art and nature, nothing is created; an equal quantity of matter exists both before and after the experiment; the quality and quantity of the elements remain precisely the same; and nothing takes place beyond changes and modifications in the combination of these elements. Upon this principle the whole art of performing chemical experiments depends: We must always suppose an exact equality between the elements of the body examined and those of the products of its analysis.

Broadly speaking, [Keynesianism means] that the government has a specific responsibility for the behavior of the economy, that it doesn't work on its own autonomous course, but the government, when there's a recession, compensates by employment, by expansion of purchasing power, and in boom times corrects by being a restraining force. But it controls the great flow of demand into the economy, what since Keynesian times has been the flow of aggregate demand. That was the basic idea of Keynes so far as one can put it in a couple of sentences.

Always mystify, mislead, and surprise the enemy, if possible; and when you strike and overcome him, never let up in the pursuit so long as your men have strength to follow; for an army routed, if hotly pursued, becomes panic-stricken, and can then be destroyed by half their number. The other rule is, never fight against heavy odds, if by any possible maneuvering you can hurl your own force on only a part, and that the weakest part, of your enemy and crush it. Such tactics will win every time, and a small army may thus destroy a large one in detail, and repeated victory will make it invincible.

There are things about organized religion which I resent. Christ is revered as the Prince of Peace, but more blood has been shed in His name than any other figure in history. You show me one step forward in the name of religion and I'll show you a hundred retrogressions. Remember, they were men of God who destroyed the educational treasures at Alexandria, who perpetrated the Inquisition in Spain, who burned the witches at Salem. Over 25,000 organized religions flourish on this planet, but the followers of each think all the others are miserably misguided and probably evil as well.
