Abstract
This is an elementary introduction to rotations in three dimensions, using reflections to naturally introduce spinors. It provides a stepping stone to higher mathematics and some new perspectives.

Joseph Samuel is a theoretical physicist at Raman Research Institute, Bangalore. He is interested in geometric and topological aspects of physics including general relativity, soft condensed matter and the geometric phase in quantum mechanics and optics. Of late he has been pursuing analogies between the cosmological constant in quantum gravity and the surface tension of fluid membranes. It’s hard work and he likes to relax by making exquisitely textured lacy appams for his friends.
