He explains the difficult topics clearly and walks through the calculations. He cares about his students and does what he can to help them succeed. Lots of homework though, and the chapters are a bit dense. Just make sure you have plenty of time to digest everything.","source_url":"https://www.ratemyprofessors.com/professor/2473104","quality_rating":5.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:43:06.364151+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTM2MDc1MTUy","source_instructor_id":"rmp:283831","instructor_name":"Duncan Carlsmith","course_label":"PHYSICS248","course_id":"PHYSICS 248","course_uid":"course_ac5b0db3a3b0f72a3723ac9e","review_date":"2022-04-14 00:54:43 +0000 UTC","comment":"pretty much the same as 247. labs are easier and have less matlab though","source_url":"https://www.ratemyprofessors.com/professor/283831","quality_rating":2.0,"difficulty_rating":3.0},{"observed_at":"2026-09-07 16:43:06.364151+00:00","run_id":"20260907T155543-ce3781c4","source_review_id":"UmF0aW5nLTMwMTA2NTYz","source_instructor_id":"rmp:283831","instructor_name":"Duncan Carlsmith","course_label":"PHYSICS248","course_id":"PHYSICS 248","course_uid":"course_ac5b0db3a3b0f72a3723ac9e","review_date":"2018-05-14 22:19:07 +0000 UTC","comment":"Slight improvement over 247. Tries to cram too many topics into the class, and I would have preferred a more intensive look at pure electromagnetism instead of circuits and quantum, which should be saved for 321 and 249, respectively.
