The 2023 Nobel Prize in physics has been awarded to Pierre Agostini, Ferenc Krausz and Anne L’Huillier for creating “flashes of sunshine which would possibly be quick sufficient to take snapshots of electrons’ extremely speedy movements,” the Royal Swedish Academy of Sciences introduced in Stockholm on Tuesday.

Electrons transfer so quickly that their movements had been beforehand thought inconceivable to comply with.

It praised the laureates for giving “humanity new tools for exploring the world of electrons inside atoms and molecules.”

The movements of electrons inside atoms and molecules are so speedy that they are measured in attoseconds ? an nearly incomprehensibly short unit of time. “An attosecond is to one second as one second is to the age of the universe,” the committee explained.

“They were capable of, in a way, present an illumination device that allows us to observe the meeting of molecules: how things come together to make a molecule,” Bob Rosner, president of the American Physical Society and a professor at the University of Chicago, told CNN.

These movements “happen so rapidly that usually we do not know how they actually happen or what the sequence of occasions is,” said Rosner. But the laureates’ work means scientists can now observe how these movements happen, he added.

“Imagine building a house. You have foundation, partitions, roof and so forth. There’s a sequence to anything complicated. For a molecule, when you don’t get the sequence proper, you won’t be ready to assemble it,” mentioned Rosner..
