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.
c.16th century BCE – Mesopotamian cosmology has a flat, circular Earth enclosed in a cosmic ocean. [ 1 ] c.15th–11th century BCE – The Rigveda of Hinduism has some cosmological hymns, particularly in the late book 10, notably the Nasadiya Sukta which describes the origin of the universe, originating from the monistic Hiranyagarbha or ...
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.
t. e. The chronology of the universe describes the history and future of the universe according to Big Bang cosmology. Research published in 2015 estimates the earliest stages of the universe's existence as taking place 13.8 billion years ago, with an uncertainty of around 21 million years at the 68% confidence level.
The Scientific Revolution was a series of events that marked the emergence of modern science during the early modern period, when developments in mathematics, physics, astronomy, biology (including human anatomy) and chemistry transformed the views of society about nature. [1][2][3][4][5][6] The Scientific Revolution took place in Europe in the ...
First flight of the Wright Flyer I, December 17, 1903, Orville piloting, Wilbur running at wingtip. One of the prominent traits of the 20th century was the dramatic growth of technology. Organized research and practice of science led to advancement in the fields of communication, engineering, travel, medicine, and war.
On the left, the dramatic expansion occurs in the inflationary epoch; and at the center, the expansion accelerates (artist's concept; neither time nor size are to scale). The Big Bang is a physical theory that describes how the universe expanded from an initial state of high density and temperature. [ 1 ]
Hubble's law, also known as the Hubble–Lemaître law, [ 1 ] is the observation in physical cosmology that galaxies are moving away from Earth at speeds proportional to their distance. In other words, the farther they are, the faster they are moving away. For this purpose, the recessional velocity of a galaxy is typically determined by ...
