I'd start with the 100+KB PNG images. None of those pictures are complex, they can be compressed much more.

  I put them all through ImageOptim, so not sure if those PNGs can compress anymore... I agree on those complexity graphs since they're actually scanned from Sean Carroll's book and edited in Pixelmator - if I was better with graphics I could probably recreate them as SVG or in an editor and make it only a couple kb. Same for the MinutePhysics screen grab, though I couldn't bring myself to attempt a poor recreation of their work and couldn't get rid of the weird pink gradient background which probably prevents better compression. The Youtube cover images are still being pulled in from youtube - I debated downloading/compressing/hosting them myself, but figured I'd gain more from downloading them from the separate domain since I still think there is a default limit of connections the browser will open to a single domain at the same time.

    That's because PNG is lossless, use JPG, and you'll dramatically cut down the space.

    Have you tried opening the image(s) in Photoshop and try outputting them at different resolutions and compression settings?
