Episode notes
Periodic Table Shape
- The periodic table isn't rectangular due to the complexity of heavier elements and their varying behaviors.
- Elements with similar properties are grouped, causing expansions beyond a simple rectangular structure.
Nature's Asymmetry
- Nature exhibits asymmetries, like the spiral growth of some tree bark, reflecting underlying molecular asymmetries.
- This challenges the notion of perfect symmetry in nature.
Chirality and Taste
- Spearmint and caraway molecules are mirror images but taste different, highlighting chirality.
- This asymmetry demonstrates how molecular structure impacts sensory perception.
