Aaron Harrison is an Assistant Professor of Chemistry at Austin College. His research in physical chemistry focuses on molecular photochemistry, spectroscopy, and computational chemistry.
A group of three researchers earned the 2023 Nobel Prize in physics for work that has revolutionized how scientists study the electron — by illuminating molecules with attosecond-long flashes of light. But how long is an attosecond, and what can these infinitesimally short pulses tell researchers about the nature of matter?
In fact, there are approximately as many attoseconds in one second as there are seconds in the age of the universe. Attosecond pulsesThe rearrangement of electrons in atoms and molecules guides a lot of processes in physics, and it underlies practically every part of chemistry. Therefore, researchers have put a lot of effort into figuring out how electrons are moving and rearranging.
As an analogy, imagine a camera that could only take longer exposures, around 1 second long. Things in motion, like a person running toward the camera or a bird flying across the sky, would appear blurry in the photos taken, and it would be difficult to see exactly what was going on.

Nobel Prize 2023 in literature goes to Norway's Jon FosseThe Nobel Prize in literature has been awarded to Norwegian author Jon Fosse. The permanent secretary of the Swedish Academy announced the prize Thursday in Stockholm. The academy says the prize is for Fosse's “innovative plays and prose, which give voice to the unsayable.” Fosse is a master of spare Nordic writing in a sprawling body of work ranging from plays to novels and children’s books. One of his country’s most-performed dramatists, Fosse said he had “cautiously prepared” himself for a decade to receive the call. He is the author of 40 plays as well as novels, short stories, children’s books, poetry and essays.
