Math and Calculus are used to create the strength of a lens that can correct our vision. Sure, computers do that mostly now  but it’s all based on math, physics and calculus. Here are pictures for those of you that are already weirded out by this post.  Math is not bad, it’s GOOD!! I know you could be traumatized by your early teachers, parents, friends that would ask, “You don’t know that?!?” or “You are wrong.” Do not let it! If the numbers stress you, think of the pictures. Circles, Squares, triangles. Not geometry theorems so much because they could also stress you. Stay in the fun side with me…
