Questions: If you have a question, please mail to 6.081-staff@mit.edu, rather than mailing a particular individual. That will ensure a quicker answer and keep all of the staff aware of the general level of questions in the class. And given our collective idiosyncratic waking hours, we have just about 24-hour coverage.Lecturers: Additional course development: Graduate teaching assistants:We love questions! Bring 'em on!!
