Story summary

In 2011, John Baez proposed "green" math to model Earth's biosphere and climate with category theory, aiming to capture complexity traditional math omits.
Recent applied category theory work shows promise in epidemiology and artificial intelligence safety, with an annual conference and new research funding.
Tom Leinster emphasizes that a chess piece's essence lies in its function rather than its form, reflecting category theory's relational focus.
