We appreciate your interest in MAS 863. Enrollment is regrettably limited by shop space and hence is by permission of the instructors; to apply, send an email message to Prof. Neil Gershenfeld (gersh at cba.mit.edu) with a subject of "MAS 863 application" briefly describing your fabrication background and interest in taking the course, and your institutional status at MIT. There is no preferred response; each semester a balance is sought between beginner and expert, serious and silly, ... . You will be notified if you have been accepted on the day after the first meeting of the class (to leave time for prospective students to apply who do not see this before then).
