Several years ago, my husband introduced me to Flatland, Edwin Abbott Abbott’s novella about a two-dimensional polygon world that also ventures into a single dimension. The social satire goes far beyond geometry, but it’s also a fascinating mental leap into a world with no depth.
In a Flatland-esque homage, Vi Hart has created a video of a Möbius world based on a triangle who lives on the infinite loop with a half twist. Most math classes pull out these strips at some point, but the creativity here comes in the narrative loop that Hart creates.
Who is this woman? Ken Chang profiled her this week in the NY Times Science section. She’d like to become “an ambassador for mathematics.” And her audience includes teenage girls. Very cool.
