The Nobel Prize in Physics for 2023 was awarded to a team of researchers for their work on attoseconds. Attoseconds are incredibly brief intervals of time – they are a quintillionth of a second (10-18). To put that into perspective, one attosecond is to one second what one second is to the age of the universe. This research has opened up an entirely new realm of possibilities for physics, allowing us to observe and measure the movement of electrons with unprecedented accuracy. The team’s work has the potential to revolutionize our understanding of chemistry and how light and matter interact.
