Motion of the Earth
“Hence, I feel no shame in asserting that this whole region engirdled by the moon, and the center of the earth, traverse this grand circle amid the rest of the planets in an annual revolution around the sun. Near the sun is the center of the universe. Moreover, since the sun remains stationary, whatever appears as a motion of the sun is really due rather to the motion of the earth.”

Ordering Others About
“It does not follow from the separation of planning and doing in the analysis of work that the planner and the doer should be two different people. It does not follow that the industrial world should be divided into two classes of people: a few who decide what is to be done, design the job, set the pace, rhythm and motions, and order others about; and the many who do what and as they are told.”

System of Nature
“The present state of the system of nature is evidently a consequence of what it was in the preceding moment, and if we conceive of an intelligence that at a given instant comprehends all the relations of the entities of this universe, it could state the respective position, motions, and general affects of all these entities at any time in the past or future. Physical astronomy, the branch of knowledge that does the greatest honor to the human mind, gives us an idea, albeit imperfect, of what such an intelligence would be. The simplicity of the law by which the celestial bodies move, and the relations of their masses and distances, permit analysis to follow their motions up to a certain point; and in order to determine the state of the system of these great bodies in past or future centuries, it suffices for the mathematician that their position and their velocity be given by observation for any moment in time. Man owes that advantage to the power of the instrument he employs, and to the small number of relations that it embraces in its calculations. But ignorance of the different causes involved in the production of events, as well as their complexity, taken together with the imperfection of analysis, prevents our reaching the same certainty about the vast majority of phenomena. Thus there are things that are uncertain for us, things more or less probable, and we seek to compensate for the impossibility of knowing them by determining their different degrees of likelihood. So it was that we owe to the weakness of the human mind one of the most delicate and ingenious of mathematical theories, the science of chance or probability.”

Time and Motion Code
“I know of one organisation that attempts to apply time and motion standards to the output of programmers. They judge a programmer by the amount of code he produces. This is guaranteed to produce insipid code”

Three Great Orders
“The whole annual produce of the land and labour of every country... naturally divides itself, it has already been observed, into three parts; the rent of land, the wages of labour, and the profits of stock; and constitutes a revenue to three different orders of people; to those who live by rent, to those who live by wages, and to those who live by profit. These are the three great, original, and constituent orders of every civilised society... The interest of the first of those three great orders, it appears from what has been just now said, is strictly and inseparably connected with the general interest of the society. Whatever either promotes or obstructs the one, necessarily promotes or obstructs the other... The interest of the second order, that of those who live by wages, is as strictly connected with the interest of the society as that of the first... Employers constitute the third order, that of those who live by profit. It is the stock that is employed for the sake of profit which puts into motion the greater part of the useful labour of every society... But the rate of profit does not, like rent and wages, rise with the prosperity and fall with the declension of the society. On the contrary... The interest of this third order, therefore, has not the same connection with the general interest of the society as that of the other two... The interest of the dealers... is always in some respects different from, and even opposite to, that of the public. To widen the market and to narrow the competition... The proposal of any new law or regulation of commerce which comes from this order ought always to be listened to with great precaution, and ought never to be adopted till after having been long and carefully examined, not only with the most scrupulous, but with the most suspicious attention. It comes from an order of men whose interest is never exactly the same with that of the public, who have generally an interest to deceive and even to oppress the public, and who accordingly have, upon many occasions, both deceived and oppressed it.”

Heat and Temperature
“Heat is the randomized motion of molecules. Heat is a feature of the microscopic structure of matter. If matter wasn't made of molecules there wouldn't be heat in the same sense. And so the concept of temperature is a feature of a characterization of the amount of randomness in these molecules... It's just the average kinetic energy of molecules... That's what defines temperature.”
