Chalkboard Dotted Line?
Ive been watching a series of MIT physics lectures, more specifically course 8.01 which can be seen on youtube, and also downloaded from itunes for free. In the professor's lectures, he draws many detailed diagrams, some including dotted lines. Ive never seen anyone do dotted lines so quickly in one motion before, so I'm wondering how this is accomplished. He'll be drawing solid lines one moment and dotted the next, so is it a special chalk holder that allows him to do this, or what?
Nope, theres no way he could be just doing that, he just does it in one fluid motion the same way he would a normal line, plus im pretty sure id have noticed if thats what he was doing
He probably just keeps his arm moving and picks up the chalk quickly to go from solid lines to dashed. Give it a shot, it's not that tough.
