atomic theory

Modern atomic theory was formulated by John Dalton, who published a book in 1808 on the atmosphere, and the behavior of gases, where he laid out a refined atomic theory that serves as his basis. Even today, it consisted of four basic ideas. Chemical elements were composed of atoms, the atoms of an element were identical in weight, the atoms of different elements had different weights, and atoms combined only in small whole number ratios, such as one to one, one to two, two to one, two to three to form compounds. Thanks to this incredible discovery, we now understand the inner workings of matter, even going so far as the subatomic level. We take the existence of bacteria for granted these days, and even use such deadly products as mouthwash to get rid of them. But bacteria were not always taken for granted. In fact, the knowledge of their existence is a fairly recent thing. And we have to thank the Dutch scientist Antony van Leeuwenhoek. For their discovery in the 17th century, Antonie discovered protozoa single celled organisms, he referred to as Unimog, coulees, or little animals and that he made refinements to the primitive microscope of his time, improving it, and creating the modern basis for the microscope, creating the foundations of modern microbiology, which is why van Leuven hook is sometimes referred to as the father of microbiology. Without this important discovery, all the science and medicine that revolves around bacteria, including but not limited to penicillin, and other antibiotics would not exist. Indeed, even people prior to the modern formulation of a theory of gravity, passively had to acknowledge his existence. But one man rose above the rest, in mapping out an actual theory that explains gravity. His name was Sir Isaac Newton. When not engaging in biblical exegesis and the workings of his alchemy, Sir Isaac Newton made some of the most important contributions to our understanding of the physical universe, the laws of universal gravitation, as formulated by Newton state, that a particle attracts every
