A Feb. 17 article about enrollment in the new biological engineering major incorrectly gave the number of students who took the subject BE.110 (Thermodynamics of Biomolecular Systems), which is required to apply for the BE major. About 100 students took the class, of whom 75 were sophomores, and 40–45 of those expressed interest in the major at the start of the term. There were not 75 students in the class as reported in the article. The same article also incompletely described MIT’s BE curriculum. While MIT’s faculty did look at the undergraduate curricula offered by other schools, the Institute’s curriculum was created from scratch and differs significantly from programs offered at other universities.
