Nobel Prize in Physics 2023

Every year, exceptional people receive Nobel Prizes for their outstanding contributions in Medicine, Literature, Chemistry, Economics, and Peace. 

This year, the Nobel Prize in Physics 2023 has been awarded to Pierre Agostini, Ferenc Krausz, and Anne L’Huillier. They conducted many experiments and invented a way to study how tiny particles like electrons move very quickly by using extremely short bursts of light. 

When two very fast-moving objects are seen by humans, we see them as a continuous flow. For example, when you watch the blades of a fast-moving fan, you cannot notice the blades moving separately. Rather, what you see is a continued motion of the blades.

To see how changes happen in electrons in a very short time (called attoseconds), scientists needed a special technology. An attosecond is even shorter than a second. Billions of attoseconds can fit inside one second.

Their invention will help scientists to see these rapid movements at a minute level, like watching the individual blades of a fast-spinning fan. This breakthrough earned them the Nobel Prize in Physics 2023.
