Three scientists were awarded the Nobel Prize on Tuesday in physics for their groundbreaking research on how electrons move around the atom during the tiniest fractions of seconds, a field that could one day lead to better electronics or disease diagnoses.
Pierre Agostini, Ferenc Krausz, and Anne L’Huillier were recognised for their study of the tiny part of each atom that races around the center and that is fundamental to virtually everything: chemistry, physics, our bodies and our gadgets.
Electrons move around so fast that they have been out of reach of human efforts to isolate them, but by looking at the tiniest fraction of a second possible — one quintillionth of a second known as an attosecond — scientists now have a “blurry” glimpse of them and that opens up whole new sciences, experts said, reported The Associated Press.
“The electrons are very fast and the electrons are really the workforce in everywhere,” Nobel Committee member Mats Larsson said. “Once you can control and understand electrons you have taken a very big step forward.”
Their experiments “have given humanity new tools for exploring the world of electrons inside atoms and molecules,” according to the Royal Swedish Academy of Sciences, which announced the prize in Stockholm. They “have demonstrated a way to create extremely short pulses of light that can be used to measure the rapid processes in which electrons move or change energy.”
At the moment, this science is about understanding our universe, but the hope is that it will eventually have many practical applications.
L’Huillier, who is only the fifth woman to receive a Nobel in physics, said she was teaching when she got the call that she had won. She joked that it was hard to finish the lesson.
“This is the most prestigious and I am so happy to get this prize. It’s incredible,” L’Huillier, of Lund University in Sweden, told the news conference announcing the prize, reported AP. “As you know there are not so many women who got this prize so it’s very special.”
Agostini is affiliated with Ohio State University in the U.S. and Krausz with the Max Planck Institute of Quantum Optics and Ludwig Maximilian University of Munich in Germany.
The Nobel Prizes carry a cash award of 11 million Swedish kronor ($1 million). The money comes from a bequest left by the prize’s creator, Swedish inventor Alfred Nobel, who died in 1896.
The physics prize comes a day after Hungarian-American Katalin Karikó and American Drew Weissman won the Nobel Prize in medicine for discoveries that enabled the creation of mRNA vaccines against COVID-19.
