ABSTRACT
The beginning of the twentieth century marked the change in the way physicists looked at the world. The quantum theory and the theory of relativity have questioned what we mean by ‘reality’ and the waveparticle duality continues to show us just how simple (we all think we understand it) and complex light really is. Lest you think that this ‘new’ physics has nothing to do with you, the quantum physics that is used to describe light is also the same physics that applies to all atoms including those in our DNA.
