Donut or Mug? |
Wikipedia GIF | This GIF would peak students interest in topology and give an example of homotopy which we could discuss. |
Stretch It: Homotopy |
GeoGebra | To understand the idea of manipulating a shape without changing its fundementals, we would learn about homotopy. This applet lets them see the transition between two curves, how a fixed point doesn't change relative position, and how there are functions connected with the tranfromations. |
How Knot Theory Could Save Your Life |
Youtube | A video by Veritasium introducing the foundations of Knot Theory. During the video, it goes through methods of proofs, 3 generalized moves, and applications of the topic. |
Untangle a Trefoil Knot |
GeoGebra | This applet would have two purposes: first for students to rotate and visualize the common trefoil knot from different angle and second once they start stretching and untangling it, they can argue how this program is not an example of homotopy as the rope can go through itself. |
Tricolor Your Own Random 3-D Knot |
GeoGebra | 3-d manipulative of knots. Starts with the trefoil knot, which can be rotated but not stretched. Can customize into a new knot by changing several parameters using a slider. Can also randomly create a new knot. |
