The Ronald E. Hatcher Science on Saturday Lecture series has been held for more than 40 years.

This annual series of lectures is given by scientists, engineers, and other professionals involved in cutting-edge research. Held on Saturday mornings throughout winter, the lectures are geared toward high school students. The program draws more than 300 students, teachers, parents, and community members. Topics are selected from a variety of disciplines.

If you can’t attend the live lecture, the talks will be posted on the Science on Saturday Archives. Recordings will be posted roughly one week after the live event.
 

The final three 2025 Ronald E. Hatcher Science on Saturday Lecture Series will be held at Maeder Hall, at the Andlinger Center, at Princeton University.
