A regular marker would be too fine to see. I | don't think that you could have a larger marker as the ink | reservoir would be large and unwieldy. Plus it would probably | drain rather quickly. | KineticLensman wrote: | > chalk is much better over longer distances in larger | classrooms | | That entirely depends on how accurately the lecturer can throw | a tiny object. IIRC some of our lecturers preferred board | rubbers to the chalk itself. | seabass-labrax wrote: | Presumably, lecturers in classical Newtonian physics have a | greater ability to effectively use difficult materials such | as chalk than those lecturers of more abstract subjects. | jjtheblunt wrote: | Oh my goodness, this article misses an unbelievable classic, and | from one of the great professors of my grad school youth, A | Topological Picturebook, by George Francis. | | https://a.co/d/8TOdLJE ___________________________________________________________________ (page generated 2023-10-31 23:01 UTC)
