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).
Such discoveries are often a multi-step, multi-person process. Multiple discovery sometimes occurs when multiple research groups discover the same phenomenon at about the same time, and scientific priority is often disputed. The listings below include some of the most significant people and ideas by date of publication or experiment.
The two Voyager spacecraft have travelled farther than any human-made object in history, and as they reach interstellar space, experts explore their most astonishing discoveries and how their extended operation has transformed into the ultimate mission.
August – Asteroid 4769 Castalia is the first asteroid directly imaged, by radar from Arecibo. August 25 – The Voyager 2 spacecraft makes its closest approach to Neptune, providing definitive proof of the planet's rings.
