Outstanding pedagogy. Excellent choice of topics. Integrates culture with science exquisitely! I found these elements to be of significant value in this course: (1) chemistry that relates to the real everyday world plus the chemistry of semiconductors, crystals, and biology (we are polymers!) (2) At every opportunity Sadoway points out how chemistry can be engineered for desired properties like recyclability or price (3) Sadoway's lectures are clear and crisp (only slightly more material than I could absorb in a sitting) (4) Sadoway always brings in culture: giving human histories, tales of ethics, playing music and clips from movies: he relates the subject to the humanities (5) professionalism: Sadoway models the values, ethics, and consideration of details that we need in future engineers or scientists.
