WebThis was their theory, and the name "atom" originates from this. In other words, there is a lower limit to the division of matter beyond which we cannot go. Atoms were impenetrably hard, meaning they could not be divided. In Greek, the prefix "a" means "not" and the word "tomos" means cut. Our word atom therefore comes from atomos, a Greek word ... WebWe explore the idea of an antiforce to explain dark matter. We imagine an electromagnetic force whose magnetic component precedes rather than lags the electric field. This, then, gives rise to the idea of dark matter, dark energy, and dark radiation.

WebDalton noted from these percentages that 100g of tin will combine either with 13.5g or 27g of oxygen; 13.5 and 27 form a ratio of 1:2. Dalton found an atomic theory of matter could elegantly explain this common pattern in chemistry - in the case of Proust's tin oxides, one tin atom will combine with either one or two oxygen atoms.
