Isamu Akasaki Life story


Isamu Akasaki was a Japanese engineer and physicist, specializing in the field of semiconductor technology and Nobel Prize laureate, best known for inventing the bright gallium nitride p-n junction blue LED in 1989 and subsequently the high-brightness GaN blue LED as well.

Nobel physics prize: 'ground-breaking' win, for the planet, and Big Bang

Feb 16,2020 6:56 am

Three scientists were awarded the 2019 with the Nobel Prize in physics for "ground-breaking" findings about The Universe .

James Peebles, Michel Mayor and Didier Queloz announced this year's winners at an event in Stockholm.

Peebles has been awarded for work on the evolution of The Universe , while Mayor and Queloz won for their discovery of a planet around a sun-like star.

The winner of The Prize share of money in the amount of nine million crowns (£738,000).

Reacting to the news, Prof Queloz told Bbc News : "It's unbelievable," adding: "Since The Discovery 25 years ago, everyone told me again and again: "It is a Nobel price-discovery". And I say: 'Oh yeah, yeah, maybe-whatever. '"

But in the following years, he is forgotten, more or less, "" about The Discovery : "I don't even think about it," he said. "Well, frankly, Yes, it came as a surprise to me. I understand the negative impact of The Discovery , but there is so much physics in The World , thought I, it is for us, we never have.

"I'm a little shocked right now, I'm trying to digest what it means. "

The cosmic microwave background represents the weak afterglow of the Big Bang

Ulf Danielsson, a member of the Nobel Committee, said: "these Two prices. are you telling us something important, something existential about our place in The Universe . "

"The First one followed the story back to an unknown origin, is so fascinating. The Other tries to find an answer to these questions: 'are we Alone , is there life elsewhere in The Universe ?'"

Winnipeg, Canada-born James Peebles was honored for his contributions to the understanding of the evolution of The Universe and the earth in the cosmos

With The Other , he predicted the existence of the cosmic microwave background (CMB) radiation, the so-called "afterglow" of the Big Bang .

By studying the CMB, scientists are able to determine the age, the Form and content of The Universe .

"Cosmic background radiation in 1965, was discovered, and proved to be a gold mine for our understanding of how The Universe developed, from Early Childhood to The Present day," said Mats Larsson , Chairman of The Physics Nobel Prize Committee.

"Were it not for the theoretical discovery of James Peebles, the wonderful high-precision measurements of this radiation over The Last 20 years have told us almost nothing. "

The 84-year-old cosmologist, who made today at Princeton University in New Jersey , USA, also made important contributions to the theory of Dark Matter and Dark Energy -of the puzzles from component, which together account for around 95% of The Universe .

In addition, he helped in the development of the theoretical framework of structure Formation describes how galaxies and other large structures that emerged from previous density fluctuations in The Universe .

Asked what he said as his most important contribution, Prof Peebles, he was to say "very difficult" and added that his work was collaborative.

"It is A Life 's work," he told the press conference at The Royal Swedish Academy of Sciences in Stockholm.

Michel Mayor and Didier Queloz were awarded The Prize for the find of 51 Pegasi b, orbiting a Gas Giant , a star 50 light-years Away .

It is The First exoplanet to be discovered orbiting a star like Our Own .

you used the pioneering radial-velocity technique. This detects Distant Worlds ends, indirectly, by measuring a parent star "wobbles", if you are tugged by the gravity of the perimeter of the planet.

The astronomers worked at the University of Geneva, Switzerland, as The Discovery was made. Mayor, 77, is Still There as a professor emeritus; Queloz, 53, now positions in Geneva and at the University of Cambridge, UK keeps.

Michael Moloney , chief executive officer of The American Institute of Physics, said: "[The Winners '] pioneering work to The Discovery of the fundamental nature of The Universe and New Worlds in distant solar systems has opened up whole new areas of research in cosmology and exoplanet science.

"The Discovery of a planet orbiting a star outside Our Own system has changed, our perceptions of our place in The Universe - a Universe that holds still many mysteries to solve. "
