Curves | Differential geometry
In the differential geometry of curves, the evolute of a curve is the locus of all its centers of curvature. That is to say that when the center of curvature of each point on a curve is drawn, the resultant shape will be the evolute of that curve. The evolute of a circle is therefore a single point at its center. Equivalently, an evolute is the envelope of the normals to a curve. The evolute of a curve, a surface, or more generally a submanifold, is the caustic of the normal map. Let M be a smooth, regular submanifold in Rn. For each point p in M and each vector v, based at p and normal to M, we associate the point p + v. This defines a Lagrangian map, called the normal map. The caustic of the normal map is the evolute of M. Evolutes are closely connected to involutes: A curve is the evolute of any of its involutes. (Wikipedia).
The idea of ‘atonement’ sounds very old-fashioned and is deeply rooted in religious tradition. To atone means, in essence, to acknowledge one’s capacity for wrongness and one’s readiness for apology and desire for change. It’s a concept that every society needs at its center. For gifts and

If God, What's Evolution? | Episode 1810 | Closer To Truth
Assuming the existence of God, what is evolution? If God does not exist, evolution is a full explanation of human origins, without deep meaning or purpose. But if God does exist, what is evolution and how did it happen? Here are possibilities. Featuring interviews with Michael Ruse, Nancey
