Now, the velocity of wave propagation can be seen, without the aid of any mathematical analysis, to depend on the elasticity of the medium and its density; for we can see that if a medium is highly elastic the disturbance would be propagated at a great speed.
I was not ready for abstraction. I clung to earth and her dear shapes, her density, her herbage, her juice. I wanted her volume, and I wanted to hear her throb.
Sashimi is velvet dust, verging on silk, or a bit of both, and the extraordinary alchemy of its gossamer essence allows it to preserve a milky density unknown even by clouds.... my cheeks recalled the effects of its profound caress.
We believe that every being is divine, is God. Every soul is a sun covered over with clouds of ignorance; the difference between soul and soul is owing to the difference in density of these layers of clouds.
There is simply no other exercise, and certainly no machine, that produces the level of central nervous system activity, improved balance and coordination, skeletal loading and bone density enhancement, muscular stimulation and growth, connective tissue stress and strength, psychological demand and toughness, and overall systemic conditioning than the correctly performed full squat.
So many of the properties of matter, especially when in the gaseous form, can be deduced from the hypothesis that their minute parts are in rapid motion, the velocity increasing with the temperature, that the precise nature of this motion becomes a subject of rational curiosity. Daniel Bernoulli, Herapath, Joule, Kronig, Clausius, &c., have shewn that the relations between pressure, temperature and density in a perfect gas can be explained by supposing the particles move with uniform velocity in straight lines, striking against the sides of the containing vessel and thus producing pressure.
If the moon and earth were not retained in their orbits by their animal force or some other equivalent, the earth would mount to the moon by a fifty-fourth part of their distance, and the moon fall towards the earth through the other fifty-three parts, and they would there meet, assuming, however, that the substance of both is of the same density.
He that can swim needs not despair to fly; to swim is to fly in a grosser fluid, and to fly is to swim in a subtler. We are only to proportion our power of resistance to the different density of matter through which we are to pass. You will be necessarily upborne by the air if you can renew any impulse upon it faster than the air can recede from the pressure.
I used to say the evening that I developed the first x-ray photograph I took of insulin in 1935 was the most exciting moment of my life. But the Saturday afternoon in late July 1969, when we realized that the insulin electron density map was interpretable, runs that moment very close.
Nature protects us in our uttermost losses by a density through which conviction is slow to penetrate.
Love, like everything else, exists in a spectrum. Love of another, love of the world, love of God, all these loves are really one love in different degrees of light and density.
Cultivate an ongoing stream of self-description, telling yourself what is happening. Get used to the idea that mind can penetrate the immediate surface of being and reveal the tactile density of it as a manifold whose measure cannot be immediately taken by the eyes, that it's deep, it's connected, it's complex. Everything holds within itself the anticipation and the memory of everything else.
There is today a frightful disappearance of living species, be they plants or animals. And it's clear that the density of human beings has become so great, if I can say so, that they have begun to poison themselves. And the world in which I am finishing my existence is no longer a world that I like.
