Putin: I don't share excitement about Greta Thunberg's U.N. speech

  Putin: I don't share excitement about Greta Thunberg's U.N. speech Russian President Vladimir Putin on Wednesday dismissed environmental activist Greta Thunberg as a kind but poorly informed teenager manipulated into making unrealistic demands in her United Nations speech last month. The 16-year-old Swede electrified the U.N. summit in New York when she denounced world leaders for failing to tackle climate change, unleashing the outrage felt by millions of her peers by demanding: "How dare you?"Putin, chairing a session at an energy forum in Moscow, said: "I may disappoint you but I don't share the common excitement about the speech by Greta Thunberg.

This was the 113th Nobel Prize in Physics awarded since 1901, of which 47 awards have been given to a single laureate. The Nobel Prize for Chemistry will be announced Wednesday, two Literature Prizes will be awarded on Thursday, and the Peace Prize comes Friday.

The 2019 Nobel prize in Physics was given to James Peebles "for theoretical discoveries in physical cosmology," and the other half jointly to Michel Peebles, of Princeton University, shares the prize with Swiss scientists Michel Mayor and Didier Queloz for their work in understanding how the universe

STOCKHOLM (AP) — A Canadian-American cosmologist and two Swiss scientists won this year's Nobel Prize in Physics on Tuesday for their work in understanding how the universe has evolved from the Big Bang and the blockbuster discovery of the first known planet outside our solar system.

Semenza for their discoveries of "how cells sense and adapt to oxygen availability," the Nobel Committee announced Monday. The discoveries made by the three men "have fundamental importance for physiology and have paved the way for promising new strategies to fight anemia, cancer and many other diseases," said the Karolinska Institute.

Physics was the prize area which Alfred Nobel mentioned first in his will from 1895. At the end of the nineteenth century, many people considered Three Laureates share this year’s Nobel Prize in Physics for their discoveries about one of the most exotic phenomena in the universe, the black hole.

Canadian-born James Peebles, 84, of Princeton University, was credited for "theoretical discoveries in physical cosmology" and Switzerland's Michel Mayor, 77, and Didier Queloz, 53, each from the University of Geneva, were honored for discovering "an exoplanet orbiting a solar-type star," said Prof. Goran Hansson, secretary general of the Royal Swedish Academy of Sciences.

Peebles, hailed as one of the most influential cosmologists of his time, will collect one half of the 9-million kronor ($918,000) cash award, and the Swiss men will share the other half.

The Nobel committee said Peebles' theoretical framework about the cosmos — and its billions of galaxies and galaxy clusters — amounted to "the foundation of our modern understanding of the universe's history, from the Big Bang to the present day."

His work set the stage for a "transformation" of cosmology over the last half-century, using theoretical tools and calculations that helped interpret traces from the infancy of the universe, the committee said. Peebles is the Albert Einstein Professor of Science at Princeton.

Mayor and Queloz were credited having "started a revolution in astronomy" notably with the discovery of exoplanet 51 Pegasi B, a gaseous ball comparable with Jupiter, in 1995 — a time when, as Mayor recalled — that "no one knew whether exoplanets existed or not."

An exoplanet is a planet outside the solar system.

"Prestigious astronomers had been searching for them for years, in vain!" Mayor quipped.

More than 4,000 exoplanets have since been found in the Milky Way since then, and "Strange new worlds are still being discovered, with an incredible wealth of sizes, forms and orbits," the committee said.

The University of Geneva quoted Mayor and Queloz as saying it was "simply extraordinary" that they won the prize for "the most exciting" discovery of their careers.

The cash prize comes with a gold medal and a diploma that are received at an elegant ceremony in Stockholm on Dec. 10, the anniversary of the death of prize founder Alfred Nobel in 1896, together with five other Nobel winners. The sixth one, the peace prize, is handed out in Oslo, Norway on the same day.

This was the 113th Nobel Prize in Physics awarded since 1901, of which 47 awards have been given to a single laureate. Only three women have been awarded it so far: Marie Curie in 1903, Maria Goeppert-Mayer in 1963 and Donna Strickland in 2018, according to the Nobel website.

On Monday, Americans William G. Kaelin Jr. and Gregg L. Semenza and Britain's Peter J. Ratcliffe won the Nobel prize for Physiology or Medicine, for discovering details of how the body's cells sense and react to low oxygen levels, providing a foothold for developing new treatments for anemia, cancer and other diseases.

Nobel, a Swedish industrialist and the inventor of dynamite, decided the physics, chemistry, medicine and literature prizes should be awarded in Stockholm, and the peace prize in Oslo.

The Nobel Prize for Chemistry will be announced Wednesday, two Literature Prizes will be awarded on Thursday, and the Peace Prize comes Friday. This year will see two literature Prizes handed out because the one last year was suspended after a scandal rocked the Swedish Academy.
