Ilya Prigogine was a famous Belgian scientist. He studied chemistry and physics. He wanted to know how things change. He looked at how energy moves through systems.

Prigogine studied something called dissipative structures. These are special parts that form when energy flows into a system. He found that this energy can make new patterns. This process is called self-organization. It helps small parts group together in new ways. This discovery helped us understand how life grows and changes.

He also thought about the arrow of time. Some science says time can go forward or backward. Prigogine argued that many things only go one way. He called this irreversibility. This includes things like the weather or how life evolves. These things cannot simply go back to how they were.

His work was very important to science. He won the Nobel Prize in Chemistry in 1977. He also won the Francqui Prize in 1955. He was a teacher in many places. He taught in Belgium and in the United States.
