Nobel Prizes in Chemistry and Physics


The News: Three scientists won the 2019 Nobel Prize for Chemistry for their pioneering work on Lithium-ion batteries.

In Physics, a scientist working on the big bang and the evolution of the cosmos won the Nobel Prize. Two other scientists who discovered the first exoplanet orbiting a star shared this prestigious award.

Chemistry: Li-ion batteries are everywhere. They are in our cars, mobile phones, and laptops and have applications in space and in the defence industry. They were invented in 1970 and made commercially viable in 1991. This energy source is portable, wireless and rechargeable. These scientists have revolutionized our lives, powering us through the digital age with smaller, smarter and more agile technology.

Physics: This year’s Nobel Prize was awarded to the researchers of radiation emitted during the evolution of the universe in the early ages and to those who discovered an exoplanet, 51 Pegasi b, orbiting a star in the Pegasus constellation, almost 50 light-years from Earth.

Why study the evolution of the universe? To understand the conditions necessary for the formation of the universe and how it behaved in the early years of its conception. Similarly, exo-planets give us the hope of Earth-like worlds where beings exist. With hundreds of exoplanet discoveries, we might be the first ones to contact them!

And the awards go to:

John D. Goodenough, M. Stanley Whittingham and Akira Yoshino for developing and refining Li-ion batteries for Chemistry, 2019.

James Peebles for his work on the evolution of the universe, and Michel Mayor and Didier Queloz for their work on the discovery of an exoplanet orbiting a star for Physics, 2019.
