She walked into Stern’s seminar that morning. He wrote a nasty problem on the board: "Decompose the tensor product of two adjoint representations of SO(10)."

It was… alive.

The manual didn't give a dry table of characters. It drew a triangle. “Label the vertices 1,2,3. Permutations are just shuffling these points. The trivial rep? Do nothing. The sign rep? Flip orientation. The 2D rep? Let the triangle live in the plane. S3 becomes the symmetries of an equilateral triangle. That’s it. That’s all the magic. Now generalize to S4, a tetrahedron. See? Group theory is just the geometry of indistinguishability.” Page after page, the manual worked miracles. It explained Lie groups by picturing a sphere and a rubber sheet. It explained Lie algebras as "the group’s whisper—what happens when you do almost nothing, over and over." It solved the problem of Casimir invariants by comparing them to the length of a vector: "The group may rotate the vector, but the length? Invariant. That’s your Casimir. That’s your particle’s mass. You’re welcome." She walked into Stern’s seminar that morning
