[2] Democritus wrote extensively on a wide ...
Most scholars agree that Leucippus existed, but some have questioned this, instead attributing his ideas purely to Democritus. Contemporary philosophers rarely distinguish their respective ideas. Two works are attributed to Leucippus (The Great World System and On Mind), but all of his writing has been lost with the exception of one sentence.
The following is a list of people who are considered a "father" or "mother" (or "founding father" or "founding mother") of a scientific field.Such people are generally regarded to have made the first significant contributions to and/or delineation of that field; they may also be seen as "a" rather than "the" father or mother of the field.

Rutherford continued to make ground-breaking discoveries long after receiving the Nobel prize in 1908. [38]: 63 Under his direction in 1909, Hans Geiger and Ernest Marsden performed the Geiger–Marsden experiment, which demonstrated the nuclear nature of atoms by measuring the deflection of alpha particles passing through a thin gold foil.

Using analogies based on the experiences of the senses, he gave a picture or an image of an atom in which atoms were distinguished from each other by their shape, their size, and the arrangement of their parts. Moreover, connections were explained by material links in which single ...
An image from John Dalton's A New System of Chemical Philosophy, the first modern explanation of atomic theory.. This timeline of chemistry lists important works, discoveries, ideas, inventions, and experiments that significantly changed humanity's understanding of the modern science known as chemistry, defined as the scientific study of the composition of matter and of its interactions.
