+    It is time to investigate what it means to have a deformation in our physics system. By deformation, I mean that the
+    vertices of our shapes are no longer fixed to one point within the model. We will begin with what I believe
+    by investigating the most common of all deformations: a weight attached to a spring in two dimensions.
