A science popularizer is someone who communicates scientific concepts and discoveries to the general public in an engaging and accessible way. They often use various media, such as books, articles, videos, and public talks, to make complex ideas understandable and interesting. Their goal is to inspire curiosity and promote scientific literacy among people of all ages. Many science popularizers, like Carl Sagan and Neil deGrasse Tyson, have made significant contributions to public understanding of science. They bridge the gap between researchers and the public, helping to demystify topics in fields such as astronomy, biology, and physics.
