John C. Baez is an American mathematical physicist and a professor of mathematics at the University of California, Riverside. He is well-known for his contributions to various fields, including category theory, quantum gravity, and mathematical physics. Baez has made significant contributions to the field of category theory, which is a branch of mathematics concerned with studying abstract structures and relationships between them. He has worked on developing higher-dimensional algebraic structures known as n-categories and their applications in physics. His work on n-categories has helped provide a rigorous foundation for understanding concepts such as symmetry in physics. In the field of quantum gravity, Baez has made important contributions to the development of loop quantum gravity. This approach attempts to reconcile general relativity and quantum mechanics by quantizing space-time itself. Baez has worked on understanding the mathematical foundations of loop quantum gravity and its implications for our understanding of the fundamental nature of space and time. Apart from his research contributions, Baez is also known for his efforts in science communication and outreach. He runs a popular blog called "Azimuth," where he discusses topics ranging from mathematics and physics to environmental issues and climate change. Through his writing, he aims to make complex scientific concepts accessible to a wider audience. Baez has received numerous awards for his work, including the Joseph Lieberman Award from the Canadian Mathematical Society and the Heineman Prize from the American Physical Society. He is widely respected in both the mathematics and physics communities for his deep insights into fundamental questions in these fields. Overall, John Baez is recognized as a leading mathematician who has made significant contributions to category theory, quantum gravity, and mathematical physics. His work continues to have a profound impact on our understanding of fundamental aspects of the universe. # References ```dataview Table title as Title, authors as Authors where contains(authors, "John Baez") or contains(authors, "John C.
