“It now appeared that the cylinder of the model, being of brass, would conduct heat much better than the cast-iron cylinders of larger engines,”

James Watt (1736–1819) British engineer

"Notes on Professor Robison's Dissertation on Steam-engines" (1769)
Context: In the winter of 1763-4, having occasion to repair a model of Newcomen's engine belonging to the Natural Philosophy class of the University of Glasgow, my mind was again directed to it. At that period my knowledge was derived principally from Desaguliers, and partly from Belidor. I set about repairing it as a mere mechanician; and when that was done, and it was set to work, I was surprised to find that its boiler could not supply it with steam, though apparently quite large enough... By blowing the fire it was made to take a few strokes, but required an enormous quantity of injection water, though it was very lightly loaded by the column of water in the pump. It soon occurred that this was caused by the little cylinder exposing a greater surface to condense the steam, than the cylinders of larger engines did in proportion to their respective contents. It was found that by shortening the column of water in the pump, the boiler could supply the cylinder with steam, and that the engine would work regularly with a moderate quantity of injection. It now appeared that the cylinder of the model, being of brass, would conduct heat much better than the cast-iron cylinders of larger engines, (generally covered on the inside with a stony crust), and that considerable advantage could be gained by making the cylinders of some substance that would receive and give out heat slowly. Of these, wood seemed to be the most likely, provided it should prove sufficiently durable. A small engine was, therefore, constructed... made of wood, soaked in linseed oil, and baked to dryness. With this engine many experiments were made; but it was soon found that the wooden cylinder was not likely to prove durable, and that the steam condensed in filling it still exceeded the proportion of that required for large engines, according to the statements of Desaguliers. It was also found that all attempts to produce a better exhaustion by throwing in more injection, caused a disproportionate waste of steam. On reflection, the cause of this seemed to be the boiling of water in vacuo at low heats, a discovery lately made by Dr. Cullen and some other philosophers... and consequently at greater heats, the water in the cylinder would, produce a steam which would in part resist the pressure of the atmosphere.

“Cézanne made a cylinder out of a bottle. I start from the cylinder to create a special kind of individual object. I make a bottle — a particular bottle — out of a cylinder.”

Juan Gris (1887–1927) Spanish painter and sculptor

“If it came on the evening news tonight that there were five grizzly bears roaming around Cobb County, do you know what would happen by six o'clock in the morning? They would all be dead. Because every redneck in four states would be out there with a rifle, trying to shoot one, right? And whoever could shoot the biggest one would be a hero. They would have his picture on the front page, "Bubba shot the Grizzly Bear" and saved the village. That is exactly what happened to the dragons. If you could figure out a way to kill a dragon, they would be telling stories about you around the campfire. People killed dragons for meat, because they were a menace, to prove that you were a hero, or to prove that you are superior, in competition for land, or for medicinal purposes. Many ancient recipes call for dragon blood, dragon bones, dragon saliva, why? Gilgamesh is famous for slaying a dragon. A Chinese legend tells about a guy named Yu that surveyed the land of China. It says, that after the Flood he surveyed the land, he divided it off into sections. He built channels to drain water off to sea and make the land livable again. Many snakes and dragons were driven from the marshlands. You know that's normal that if you want to build a city. You have to drive off the dragons, then build your city. It was expected that you have got to drive the dragons away or kill them. Why would the Chinese calendar have eleven real animals: the pig, the duck, the dog, and … the dragon? Why would they put just one "mythical" animal in there? Could it be at the time they that they came up with these animals there were 12 real animals? There is one of the oldest pieces of pottery on Planet Earth. It's a piece of slate from Egypt; the first dynasty of United Egypt. It shows long necked dragons […] Why would they put long necked dinosaurs on pottery 3,800 years ago? Here are two long necked dinosaurs with a sheep in between them in their mouths. Here is a hippo tusk from the twelve century B. C., showing an animal with a long neck, and a long tail. Here's a cylinder seal, showing what appears quite obviously to be a long neck dinosaur. The Bible talks about a fiery flying serpent, in Isaiah 14.”

“My experience of the original Edison phonograph goes back to the period when it was first introduced into this country. In fact, I have good reason to believe that I was among the very first persons in London to make a vocal record, though I never received a copy of it, and if I did it got lost long ago. It must have been in 1881 or 1882, and the place where the deed was done was on the first floor of a shop in Hatton Garden, where I had been invited to listen to the wonderful new invention. To begin with, I heard pieces both in song and speech produced by the friction of a needle against a revolving cylinder, or spool, fixed in what looked like a musical box. It sounded to my ear like someone singing about half a mile away, or talking at the other end of a big hall; but the effect was rather pleasant, save for a peculiar nasal quality wholly due to the mechanism, though there was little of the scratching which later was a prominent feature of the flat disc. Recording for that primitive machine was a comparatively simple matter. I had to keep my mouth about six inches away from the horn and remember not to make my voice too loud if I wanted anything approximating to a clear reproduction; that was all. When it was played over to me and I heard my own voice for the first time, one or two friends who were present said that it sounded rather like mine; others declared that they would never have recognised it. I daresay both opinions were correct.”

“The centre of gravity of any cylinder is the point of bisection of the axis.”

Proposition presumed from previous work.
The Method of Mechanical Theorems

“We are now in the middle of a long process of transition in the nature of the image which man has of himself and his environment. Primitive men, and to a large extent also men of the early civilizations, imagined themselves to be living on a virtually illimitable plane. There was almost always somewhere beyond the known limits of human habitation, and over a very large part of the time that man has been on earth, there has been something like a frontier…
Gradually, however, man has been accustoming himself to the notion of the spherical earth and a closed sphere of human activity. A few unusual spirits among the ancient Greeks perceived that the earth was a sphere. It was only with the circumnavigations and the geographical explorations of the fifteenth and sixteenth centuries, however, that the fact that the earth was a sphere became at all widely known and accepted. Even in the thirteenth century, the commonest map was Mercator's projection, which visualizes the earth as an illimitable cylinder, essentially a plane wrapped around the globe, and it was not until the Second World War and the development of the air age that the global nature of tile planet really entered the popular imagination. Even now we are very far from having made the moral, political, and psychological adjustments which are implied in this transition from the illimitable plane to the closed sphere.”

“On the train I was going over the problem of Sixes versus Fours and the disturbing periodic vibrations with which the 'six-cylinder manufacturers were contending. I realized the emphasis our competitors were placing on the fact that six smaller cylinders, producing the same maximum power as four larger ones, would result in smaller individual impulses, and consequent smoother action.
I knew that we were having good results with well-balanced four-cylinder motors. I first reasoned that if six light cylinders gave the same maximum power and lighter impulses than the tour, then eight still smaller cylinders would give still lighter impulses than the six cylinders. I also reasoned that, because of the lighter weight, those eight cylinder pistons could be run at higher speeds than either sixes or fours. Furthermore I did not like the six crankshaft. If made small enough to be in proportion with those light pistons, the extra length might introduce those undesirable vibrations; if made heavy enough to avoid; if made heavy enough to avoid these periodic vibrations there was the wight problem contend with.
As I lay awake pondering these factors, the idea came to me that we were having good success with four-cylinder motors; we would surely have equally good results with blocks of lighter four cylinders and pistons. Why not make up those smaller blocks of lighter four cylinders and pistons, and put two of the blocks together at an angle and avoid that troublesome long crankshaft. The more I thought of this idea on that trip, the more convinced I became that it could be worked out.”

“My first essay at making a steam engine was when I was fifteen. I then made a real working; steam-engine, 1 3/4 diameter cylinder, and 8 in. stroke, which not only could act, but really did some useful work; for I made it grind the oil colours which my father required for his painting. Steam engine models, now so common, were exceedingly scarce in those days, and very difficult to be had; and as the demand for them arose, I found it both delightful and profitable to make them; as well as sectional models of steam engines, which I introduced for the purpose of exhibiting the movements of all the parts, both exterior and interior. With the results of the sale of such models I was enabled to pay the price of tickets of admission to the lectures on natural philosophy and chemistry delivered in the University of Edinburgh. About the same time (1826) I was so happy as to be employed by Professor Leslie in making models and portions of apparatus required by him for his lectures and philosophical investigations, and I had also the inestimable good fortune to secure his friendship. His admirably clear manner of communicating a knowledge of the fundamental principles of mechanical science rendered my intercourse with him of the utmost importance to myself. A hearty, cheerful, earnest desire to toil in his service, caused him to take pleasure in instructing me by occasional explanations of what might otherwise have remained obscure.”

“It is not given to a cylinder to move everywhere by its own motion,”

X, 33
Meditations (c. 121–180 AD), Book X
Context: It is not given to a cylinder to move everywhere by its own motion, nor yet to water nor to fire nor to anything else which is governed by nature or an irrational soul, for the things which check them and stand in the way are many. But intelligence and reason are able to go through everything that opposes them, and in such manner as they are formed by nature and as they choose. Place before thy eyes this facility with which the reason will be carried through all things, as fire upwards, as a stone downwards, as a cylinder down an inclined surface, and seek for nothing further. For all other obstacles either affect the body only, which is a dead thing; or, except for opinion and the yielding of reason itself, they do not crush nor do any harm of any kind; for if they did, he who felt it would immediately become bad.
