Quotes About Density

Manhattanism is the one urbanistic ideology that has fed, from its conception, on the splendors and miseries of the metropolitan condition—hyper-density—without once losing faith in it as the basis for a desirable modern culture. Manhattan's architecture is a paradigm for the exploitation of congestion.

The problem of stability is then: Is the collection of structurally stable vector fields everywhere dense in the space B of all vector fields? A partial answer has been obtained recently: yes, when dimension m is less than or equal to 2 (Peixoto[18]), no when dimension m is greater than or equal to 4(Smale[22]), or 3 (Smale and Williams[24]).

None of this nine or ten nonsense and I don't care what the parish priest says. There will soon be so many people on this planet that it will be standing room only.

Evangelista Torricelli. Torricelli's experiments led to the invention of the mercury-column barometer, which responds to changes in air pressure—that is, to changes in the density of the column of air above the instrument.

His soul is too dense. If he comes out, he'll dissolve into pieces, like a deep-sea fish pulled to the surface too quickly. I suppose my job is to go on holding him here at the bottom of the sea.

So you have density, infectivity, mortality, and recovery—four factors interrelated as fundamentally as heat, tinder, spark, and fuel. Brought together in the critical measure of each, the critical balance, they produce fire: epidemic.

Another implication was that epidemics don't end because all the susceptible individuals are either dead or recovered. They end because susceptible individuals are no longer sufficiently dense within the population.

Nevertheless, there will always lurk, around a corner in a pocket of our knowledge of the odds, an indefensible hope, and this was one of the times, which you now and then find in sports, when a density of expectation hangs in the air and plucks an event out of the future.

todo es cada vez más veloz, menos duradero, y se da de baja y se archiva más pronto, y nuestro pasado se hace cada vez más denso y amontonado y nutrido porque se decreta —y aun llega a creerse— que el ayer es ya caduco y el anteayer sólo historia, e inmemorial lo de hace un año.

You need an infinite stretch of time ahead of you to start to think, infinite energy to make the smallest decision. The world is getting denser. The immense number of useless projects is bewildering. Too many things have to be put in to balance up an uncertain scale. You can't disappear anymore. You die in a state of total indecision.

there was a sheathing from stem to stern of greenheart, a wood so heavy it weighs more than solid iron

The density of space junk peaks around 620 miles up, in the middle of so-called low-Earth orbit. That's bad, because many weather, scientific, and reconnaissance satellites circle in various low-Earth orbits.

When I was writing the first few books, what I would do is write a bunch of sentences and then go back and expand and explode those sentences, pack as much into them as I could, so they'd kind of be like popcorn kernels popping... all this stuff in there to make the writing dense, and beautiful for its density.

In Hong Kong there is agglomeration beyond my fondest imaginings. The Kowloon district claims a population density four times that of New York City.

Cities are 2% of the earth's crust, but they are 50% of the world's population.

Without strong health systems in place, the higher the population density, the more difficult it becomes to prevent and control outbreaks, and not just because of the increased risk of contagion.

A result of the government program, therefore, was the increased population density that turned the African American neighborhoods into slums.

Even at relatively low population densities, sprawl tends not to pay for itself financially and consumes land at an alarming rate, while producing insurmountable traffic problems and exacerbating social inequity and isolation.

The air we breathe has about 1019 atoms in each cubic centimeter—and we usually think of air as empty space.

In Europe, it's common to hear about young professionals living with their parents. With the continent's high rents and taxes and its population density, it makes sense.

Por estudios realizados sobre otras especies en estado de superpoblación experimental, sabemos que llega un momento en el que el aumento de densidad de población alcanza un punto extremo en el que se destruye toda la estructura social.

In fact, if you have a very large volume of mass at constant density, then it is guaranteed to become a black hole if the volume is large enough — no matter how small the density! [13] This means that if we had a large volume of soft cotton wool, with a uniformly low density, it would collapse to form a black hole as long as the volume was large enough.

Whenever you look at light, basically it's just air. It has no tactileness to it. It's totally without density.
