Course Textbook

David Griffiths, Introduction to Elementary Particles

Please buy the book, or at least get a physical or electronic copy!

Reading in the book will be essential in this course!


Homeworks will be provided here every Friday during the semester.

Please return your solutions electronically (preferrably as a PDF document) directly to Marc Barroso,

People who average above 60% on their homework, after discarding the lowest-scoring homework, will receive a bonus to the final course grade of 0.3 or 0.4 points.

Exam schedule

Who cares? See below

Note about the exam

By unanimous vote, the students and professor agree that an exam is unnecessary. Instead we will grade solely on homeworks.

That said, there will be a final homework assignment which is in some sense comprehensive over what we have covered.

Lecture schedule

All readings refer to the relevant chapters of the course book by Griffiths.
