Subatomic World

credits

Average Course Rating

(4.24)

Introduction to the concepts of physics of the subatomic world: symmetries, relativity, quanta, neutrinos, particles and fields. The course traces the history of our description of the physical world from the Greeks through Faraday and Maxwell to quantum mechanics in the early 20th century and on through nuclear physics and particle physics. The emphasis is on the ideas of modern physics, not on the mathematics. Intended for non-science majors.

The best aspect of this course was the outgoing professor who effectively delivered the subject material in an easy and understandable way. Students also liked the demonstrations and experiments. The worst aspects of the course included the vague guidelines and expectations for the exams. The course would improve if students had a clear outline of what they were expected to know, and perhaps more practice problems to help them understand the content. Prospective students should take this highly recommended class, as it is very informative to both science and non-science majors, even without 236 previous background knowledge. Students who want to be successful should take notes and take advantage of all the lecture materials.

Students found that the best aspect of this course was the professor, who was able to break down complex Physics concepts into manageable and comprehensible examples. The content was interesting, and students found the professor very knowledgeable and open to questions throughout the lecture. Students did miss having a textbook to review concepts, and felt it was nearly impossible to catch up with the notes if they missed a lecture. Students suggested posting the lecture notes online, providing links to related reference materials, or assigning a textbook might help when studying. They also wanted to see more demonstrations, as they found these to be very helpful and entertaining. Students considering this course must be willing to attend every lecture. The workload is manageable and the course is highly recommended for anyone with an interest (but not necessarily a background) in science.

Students broadly praised this course for having a ‘wonderful’ and ‘entertaining’ instructor who explained complex subjects in a simple and understandable way. Perceived issues with the course varied; many students didn’t have any issues with the course while other students found that the content of the course could be difficult and dry to fol ow. Suggestions for improvement varied and included a belief that the course could be improved if there were more in-class examples. Prospective students should know that students complemented this course for having a gifted instructor, a manageable workload and for being a course that was welcoming to those without a strong science background.
