Matter, though divisible in an extreme degree, is nevertheless not infinitely divisible. That is, there must be some point beyond which we cannot go in the division of matter. ... I have chosen the word “atom” to signify these ultimate particles.
Interpretation
Matter has a fundamental limit to its divisibility, known as atoms.
This quote by John Dalton emphasizes the idea that matter is not infinitely divisible and that there are ultimate building blocks, which he refers to as 'atoms'. Dalton's assertion laid the groundwork for the atomic theory, suggesting that all matter is composed of these indivisible particles, fundamentally changing the understanding of chemistry and physics.
In practice
In a science lecture about atomic theory, this quote could illustrate the concept of matter.
No new creation or destruction of matter is within the reach of chemical agency. We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen.
My fundamental premise about the brain is that its workings - what we sometimes call "mind" - are a consequence of its anatomy and physiology, and nothing more.
It is interesting thus to follow the intellectual truths of analysis in the phenomena of nature. This correspondence, of which the system of the world will offer us numerous examples, makes one of the greatest charms attached to mathematical speculations.
Windmills installed around the world converting their direct current into alternating current and feeding the electric energy into the world network can harvest the planet Earth's prime daily energy income source-the wind--and adequately supply all the world's energy needs
We're always, by the way, in fundamental physics, always trying to investigate those things in which we don't understand the conclusions. After we've checked them enough, we're okay.
There is fuel in every bit of vegetable matter that can be fermented. There's enough alcohol in one year's yield of an acre of potatoes to drive the machinery necessary to cultivate the fields for a hundred years.
I had a bet with Gordon Kane of Michigan University that the Higgs particle wouldn't be found.
