1971: Place cells in the brain are discovered by John O'Keefe. 1974: Russell Alan Hulse and Joseph Hooton Taylor, Jr. discover indirect evidence for gravitational wave radiation in the Hulse–Taylor binary. 1977: Frederick Sanger sequences the first DNA genome of an organism using Sanger sequencing.
The discoveries of the 118 chemical elements known to exist as of 2024 are presented here in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined. There are plans to synthesize more elements, and it ...
The timeline of discovery of Solar System planets and their natural satellites charts the progress of the discovery of new bodies over history. Each object is listed in chronological order of its discovery (multiple dates occur when the moments of imaging, observation, and publication differ), identified through its various designations (including temporary and permanent schemes), and the ...
The Discoverers. The Discoverers is a non-fiction historical work by Daniel Boorstin, published in 1983, and is the first in the Knowledge Trilogy, which also includes The Creators and The Seekers.

Henry Hudson (c.1565–c.1611) explored what is now New York and northeastern Canada. Today he has both a river and bay named after him. Abel Tasman (1603–1659) was a Dutch seafarer who was the first known European to sight the islands of Tasmania (named after him), New Zealand, and Fiji (1642–43). James Cook (1728–1779).
The discovery of these particles required very different experimental methods from that of their ordinary matter counterparts, and provided evidence that all particles had antiparticles—an idea that is fundamental to quantum field theory, the modern mathematical framework for particle physics. In the case of most subsequent particle ...
1610 – Galileo Galilei: discovered the Galilean moons of Jupiter. 1613 – Galileo Galilei: Inertia. 1621 – Willebrord Snellius: Snell's law. 1632 – Galileo Galilei: The Galilean principle (the laws of motion are the same in all inertial frames) 1660 – Blaise Pascal: Pascal's law. 1660 – Robert Hooke: Hooke's law.
In 2018, archeologists from Cairo University and the University of Catania reported the discovery of the oldest known cheese from Egypt. Discovered in the Saqqara necropolis, it is around 3200 years old. [237] Earlier, remains identified as cheese were found in the funeral meal in an Egyptian tomb dating around 2900 BC. [238]
