The Nobel physicist on Tuesday honored three prominent cosmologists, Canadian-American James Peebles and Swiss Mayor Michel and Didier Queloz.
Price goes half James Peebles for his " theoretical discoveries in physical cosmology "And for the second half, along with Mayor Michel and Didier Queloz"the discovery of an exoplanet orbiting a solar-type starSaid Göran Hansson, Secretary General of the Royal Swedish Academy of Sciences.
Three researchers, astrophysicists and astronomers, contributed "a new understanding of the structure and history of the universe".
" Their work has forever changed our understanding of the world Academy added.
James Peebles is interested in the universe, with its billions of galaxies and clusters of galaxies. Its theoretical framework, developed over two decades, plunges into the genesis of the universe, from the Big Bang to the present.
Michel Mayor and Didier Queloz explored our galaxy, the Milky Way, in search of unknown worlds. In 1995, they made the first discovery of a planet outside our solar system: an exoplanet orbiting a solar-type star, 51 Pegasi b.
In a statement issued by the University of Geneva, they recalled their " excitation When they made this discovery. " Nobel Prize winner, it's just extraordinary They added.
For chemistry, Nobel on Wednesday awarded the trio – American John Goodenough, Briton Stanley Whittingham and Japan's Akira Yoshino – for inventing lithium-ion batteries, present in many everyday technologies.
" This type of lightweight, rechargeable, and powerful battery is used everywhere, in phones and laptops and electric vehicles Said the Royal Swedish Academy of Sciences awarding the award.
" It can also store significant amounts of solar and wind energy and pave the way for a fossil-free society She added.
In the midst of the oil crises of the 1970s, Stanley Whittingham set out to find non-fossil energy sources.
This creates an innovated cathode in a lithium titanium disulfide (TiS2) battery.
John Goodenough, who at the age of 97 became the oldest Nobel laureate in history, then predicted that the properties of this cathode could be enhanced if obtained from metal oxide instead of disulfide.
1980 showed that a combination of cobalt oxide and lithium ions can produce up to 4 volts.
Akira Yoshino then created the first commercial battery in 1985.
Mendele's first metal table, lithium is also the lightest, popular feature for electronic devices.
Medicine on Monday opened the Nobel Prize for the coronation of two Americans, William Kaelin and Gregg Semenza, as well as Britain's Peter Ratcliffe, the author of the findings on the adaptation of cells to oxygen deficiency, which opens up promising prospects in the world. treatment of cancer and anemia.
