Gases are distinguished from other forms of matter, not only by their power of indefinite expansion so as to fill any vessel, however large, and by the great effect heat has in dilating them, but by the uniformity and simplicity of the laws which regulate these changes.
Interpretation
Gases have unique properties that allow them to expand and fill any space, influenced significantly by heat.
In this quote, James Clerk Maxwell emphasizes the distinct characteristics of gases that set them apart from other states of matter. He highlights their ability to expand indefinitely to occupy any space and the critical role that heat plays in this process, alongside the simplicity and uniformity of the laws governing these behaviors, which makes understanding gases fundamentally different from understanding solids and liquids.
In practice
In a physics lecture discussing the properties of gases.
Science appears to us with a very different aspect after we have found out that it is not in lecture rooms only, and by means of the electric light projected on a screen, that we may witness physical phenomena, but that we may find illustrations of the highest doctrines of science in games and gymnastics, in travelling by land and by water, in storms of the air and of the sea, and wherever there is matter in motion.
... that, in a few years, all great physical constants will have been approximately estimated, and that the only occupation which will be left to men of science will be to carry these measurements to another place of decimals.
Very few of us can now place ourselves in the mental condition in which even such philosophers as the great Descartes were involved in the days before Newton had announced the true laws of the motion of bodies.
What's the go of that? What's the particular go of that?
I have also a paper afloat, with an electromagnetic theory of light, which, till I am convinced to the contrary, I hold to be great guns.
If we betake ourselves to the statistical method, we do so confessing that we are unable to follow the details of each individual case, and expecting that the effects of widespread causes, though very different in each individual, will produce an average result on the whole nation, from a study of which we may estimate the character and propensities of an imaginary being called the Mean Man.
We have such a terrible, terrible misconception of science. We think it involves the definite, the precise, the known; it is a horrid series of gates to an unknown as vast of the universe; which means endless.
If your economy grows [by] 4 percent, you ought to reduce child mortality 4 percent.
The facts will eventually test all our theories, and they form, after all, the only impartial jury to which we can appeal.
We are here to celebrate the completion of the first survey of the entire human genome. Without a doubt, this is the most important, most wondrous map ever produced by human kind.
The growth of our understanding of the world through science weakens some of the motivation which makes people believers. But that's not the same thing as saying they're incompatible. It's just that I think some of the traditional reasons for belief, going back thousands of years, are rather undermined.
[Decoding the human genome sequence] is the most significant undertaking that we have mounted so far in an organized way in all of science. I believe that reading our blueprints, cataloguing our own instruction book, will be judged by history as more significant than even splitting the atom or going to the moon.
