Charles Darwin (1809-1882)
Charles Darwin is a well-known scientist. One thesis that brought him a lot of attention was the Natural Selection and Evolution thesis. Darwin had gone out and collected many fossils, rocks and samples form plants and animals after he traveled around the world in 1831. What caught his attention were all the fossils of extinct animals and his curiosity led to why they went extinct. Also, the change and progression within a family of animals which lead to his evolution discovery. -
Niels Bohr (1885-1962)
Bohr greatest contribution to science was his atomic atom model. It had just been discovered about the atom containing a heavy positive charge. Bohr believed that electrons would be able to jump to different orbits and that only occurred when the electromagnetic radiation was lower in another atom. At first scientist did not agree with Bohr, but that was until he came out with his model. Bohr's atomic model was able to show that his theory was true. -
Pierre Duhem (1861-1916)
The Quine- Duhem Thesis stated, "is a form of the thesis of the underdetermination of theory by empirical evidence." Duhem argument was that if you wanted to make a statement true you would just have to adjust another statement to make it a true statement. Quine focused his bases off making drastic adjustment to the statement it will eventually make the conflict go away and it will then become a true statement. From both their thesis's it created the Quine-Duhem thesis. -
Karl Popper (1902-1994)
Popper came up with the theory of Falsification. "For Popper, science should attempt to disprove a theory, rather than attempt to continually support theoretical hypotheses." since a theory can never be fully proven since new discoveries and evidence is constantly being discovered, Popper believed in disproving theories. Through Falsification it was a way to test the hypothesis of the experiment to attempt to disprove it.
