Quotes About Density

The proportionality constant is 21.6, meaning that there is approximately one establishment for about every 22 people in a city, regardless of the city size.

Does ice float?

We have this interesting problem with black holes. What is a black hole? It is a region of space where you have mass that's confined to zero volume, which means that the density is infinitely large, which means we have no way of describing, really, what a black hole is!

The tall building, concentrating man in one place more densely than ever before, similarly concentrates the dilemma of our public architecture at the end of the twentieth century: whether the new forms made possible by technology are doomed by the low calculations of modern patrons and their architects.

Look closely, and you can see where the grooves of a record widen, indicating a sparseness that can only be a bass solo, or grow denser to accommodate a cresting density of sound.

I hope that any expansion of London will learn from the planning examples of some of its most desirable areas such as Chelsea, Notting Hill, Belgravia and Mayfair. All are characterised by high density and a generosity of green spaces.

According to the strange mathematics of the god of mutual affinity, the shadows that clouded their pasts when united became only half as dense instead of darker. - The World And The Door

Britain had just converted its entire fleet from the unsteady power of wind to the constant force provided by coal. Now, Churchill declared, Britain had to transform its navy a second time. Burning a pound of fuel oil produces about twice as much energy as burning a pound of coal. An oil-fueled ship could thus travel roughly twice as far as a coal-fueled ship of similar size. Oil's greater energy density meant that it, rather than coal, was the fossil fuel of choice.

When Columbus landed, Cook and Borah concluded, the central Mexican plateau alone had a population of 25.2 million. By contrast, Spain and Portugal together had fewer than ten million inhabitants. Central Mexico, they said, was the most densely populated place on earth, with more than twice as many people per square mile than China or India.

He probably wouldn't give her an opening (Robin was a perfectly spherical branch manager of uniform density: he had no handles or rough edges for blackmail)

I'm really sorry, sir, I was working on a final solution to the packing density problem in the sub-subbasement—" she glanced sideways at the dog-eared paperback lying facedown on her desk, copiously annotated: Stiff: The Curious Lives of Human Cadavers, by Mary Roach—"and I may have become slightly distracted.

most of the inhabitants of Dirt were crowded into a pawful of major cities, while most of the surfaces of the main land masses were barely inhabited at all.

Ah, Gwendolyn, while it may be true that "everyday existence' is the tirl of dull, repetitive activities that you infer, it's just one layer of a many-layered cake; and if it seems an exercise in pointless mediocrity, maybe that's only because most who live it are too narrowly focused to perceive its underlying kaleidoscopic density.

Pulses themselves have a digital character, for they are normalized in intensity and duration; they are therefore digital, but their density (the number of pulses per unit time) can have any number of intermediate values, and it is therefore analog in character. A commonly-held opinion today is that the human nervous system operates on this principle.

By scrapping the government's centrally dictated density targets we'll ensure that the right type of new homes are built where they're needed, ending the glut of one- and two-bedroom flats.

Certain kinds of speed, flow, intensity, density of attacks, density of interaction... Music that concentrates on those qualities is, I think, easier achieved by free improvisation between people sharing a common attitude, a common language.

And behold the greatest mystery of them all: an unopened can of diet Pepsi floats in water while an unopened can of regular Pepsi sinks.

During the quark–lepton era the universe was dense enough for the average separation between unattached quarks to rival the separation between attached quarks.

A millionth of a second has passed since the beginning. This tepid universe was no longer hot enough or dense enough to cook quarks, and so they all grabbed dance partners, creating a permanent new family of heavy particles called hadrons (from the Greek hadros, meaning "thick").

iridium is one of the three heaviest (densest) elements on the Table—two cubic feet of it weighs as much as a Buick, which makes iridium one of the world's best paperweights, able to defy all known office fans.

If you feed a black hole, its event horizon (that boundary beyond which light cannot escape) grows in direct proportion to its mass, which means that as a black hole's mass increases, the average density within its event horizon actually decreases. Meanwhile, as far as we can tell from our equations, the material content of a black hole has collapsed to a single point of near-infinite density at its center.

Ordered it with whipped cream, of course. When it arrived at the table, I saw no trace of the stuff. After I told the waiter that my cocoa had no whipped cream, he asserted I couldn't see it because it sank to the bottom. But whipped cream has low density, and floats on all liquids that humans consume. So I offered the waiter two possible explanations: either somebody forgot to add the whipped cream to my hot cocoa or the universal laws of physics were different in his restaurant.

Frozen water is less dense than liquid water…and ice floats. In the winter, the top surface [of a lake] gets cold. The top water will freeze, and not drop, thereby insulating the liquid water below, protecting the fishes through the winter months. It's a remarkable feature of water.

In recent years, astronomers have discovered that not all stars shine. There are some stars of such tremendous density, instead of radiating outwards they only draw light in. Therefore, they have named these stars, "Black Holes." Fortunately, the universe has enough Black Holes already. If you have light, shine forth.
