    I know most of these formulae, in the coming months I'll know all of these.

    They're all in my syllabus o_O

    I took physics as a freshmen and hated it with a burning passion. I did really well, which kind of made me hate it more for some reason, so now I just take chemistry which is a lot more enjoyable.

    im a white girl and I comprehend almost all of this without an issue.

    computer science major, i need this info or i die

    **edit: also, not sure if you made this list or not, but imo i'd put waves (- optics) under modern physics. but hey thats just me :p
    Also just me, but the lamta (wave symbol) has always reminded me of a wishbone. it's wonderful.
