λ · μ = lk(∂λ, ∂μ) + ∑ handles intersections

Watching Lisa Piccirillo own the blackboard like this; intersection forms on homology modules, handle cancellations in 4-manifolds; hits different. The precision, the chalk dust, the way she just sees the topology.

This is pure 4D magic: where smooth vs topological distinctions go wild, and one clever trace or form can kill a 50-year knot problem.

Her Conway knot proof lives here; showing it's not smoothly slice, unlocking exotic phenomena that change how we understand spacetime surgery and manifold classification.

I am 90. And I say the best investment advice is "think long-term and in decades." Most don't take this advice seriously may be because of my age.

It s known that there are 2 risks in investing: one is to lose money & the other is to miss opportunity but there is a greater than both: the paradox of selling an investment too early! #ValueInvesting #investing
