atomic theory

Manchester had been steadily attracting scientific prestige after John Dalton pioneered studies in atomic theory and colour blindness, while fellow student James Joule became a household name after his work in energy conservation.

Thus, the atomic theory required that the universe be filled with emptiness—an infinite void.

These fluids mix well together in outer portions of such a planet’s deep interior, but in the depths, the tenets of atomic theory predict they will “unmix” like water and oil.

Scientific advances like X-rays and atomic theory seemed to reinforce the existence of a truth beyond appearances.

The progress in chemistry in the 19th century depended on the atomic theory.
