Mirros and
Lenses Begins With an M (QuickTime) Part of the "Physics Begins with an M" series. Interactive slideshow: click the image to advance to the next slide. Requires QuickTime. Mirrors and Lenses Begins With an M Keynote A nifty Keynote presentation of the M's. Requires Keynote. (Keynote is Apple's presentation software; PowerPoint is Microsoft's presentation software.) Trust me, neither Keynote nor PowerPoint are The Great Saviors of education. I recommend using them sparingly if at all. Better to teach! |
