Answer
In the 1940s, Toshihide Maskawa was born in Nagoya, Japan. He went on to become a renowned theoretical physicist, most notably known for his work on the Cabibbo-Kobayashi-Maskawa (CKM) matrix, which describes the mixing of quark flavors in the Standard Model of particle physics. This breakthrough discovery helps explain why the universe contains more matter than antimatter, and he shared the 2008 Nobel Prize in Physics for his contributions.
