An Italian circumnavigation of the globe that made important scientific observations in South America. The purpose of the trip was also to establish diplomatic relations with China and Japan, but without success. De Filippi set out in 1866 on a government-sponsored scientific voyage to circumnavigate the globe.
The Scientific Revolution occurs in Europe around this period, greatly accelerating the progress of science and contributing to the rationalization of the natural sciences. 16th century: Gerolamo Cardano solves the general cubic equation (by reducing them to the case with zero quadratic term).

[121] 1869 – American naturalist John Wesley Powell leads the first expedition to travel the entire length of the Colorado River through the Grand Canyon.
1021 – Ibn al-Haytham (Alhacen) pioneers the experimental scientific method and experimental physics in his Book of Optics, where he devises the first scientific experiments on optics, including the first use of the camera obscura to prove that light travels in straight lines and the first experimental proof that visual perception is caused ...
This timeline lists significant discoveries in physics and the laws of nature, including experimental discoveries, theoretical proposals that were confirmed experimentally, and theories that have significantly influenced current thinking in modern physics. Such discoveries are often a multi-step, multi-person process.
