Welcome to Intro to Modern Physics!
My name is Mohammad and I'm here to help you ace your PHYS 1AA3 course :)

This Wize course is still in beta, meaning that some of the videos are still being developed, we might have missed some topics that you need, and we may have included some topics that are not covered in your course (we did our best with the course syllabus that was given by McMaster). 

We need your help to make this course even better! If you notice any missing topic or any topic that should be removed from this course, please let us know and we'll get right on it (click on the little speech bubble in the bottom right corner of your screen).
