Episode notes
Feynman's Letter
- Grant Sanderson admires Richard Feynman's constant desire to reinvent concepts.
- He highlights a letter Feynman wrote to his deceased wife, revealing a deeper emotional side.
Rediscovering Concepts
- For deep learning, rediscover core concepts yourself before reading others' work.
- This builds stronger intuition, but balance it with efficient learning from existing proofs.
Topology's True Nature
- Topology is often wrongly popularized as the study of bending and stretching surfaces without cutting or gluing.
- Mathematicians view it as a general structure, like geometry without exact distances, enabling mappings with non-trivial implications.
