Thanks for all the positive feedback and new ideas! This is why I love the Tumblr math community. Based on your suggestions and remarks, some other designs:
- A heart-filled matrix for linear algebra:
- Cryptography gets a bitstream encoding a heart:
- Complex analysis with a heart-shaped contour integral:
- A logical Boolean circuit:
- Another cardioid for geometry:
Still to do: number theory, algebra, combinatorics, perhaps trigonometry?
