What happens when you see something that just doesnt make sense? Perhaps you rub your eyes and consider it an anomaly. But what if you see it in an experiment? Say, travelling electrons that make different patterns depending upon whether they were detected? Then, you might want to change your sense of reality. Now, if you can develop a theory for the observations, then maybe you can start a new field of science. It has happened. Quantum mechanics is the name given to this relatively new field and its the topic that Sean Carroll writes in his book, The Biggest Ideas in the Universe Quanta and Fields. In his book, theres much ado about particles, fields, groups and diagrams; all with the aim of enabling any reader to make sense of it.
