What do traffic jams, stock market crashes, and wars have in common? They are all explained by complexity, an unsolved scientific puzzle which is considered by many to be the 'Science of Sciences'. In Two's Company, Three is Complexity, Neil Johnson uses real-life examples as he leads us on a fascinating and entertaining romp through cutting-edge topics like chaos, game theory, economics, and even jazz and quantum physics. From pubs to plants, Johnson shows the surprising ways in which order eventually emerges from the interaction of all things, and ultimately proves that complexity lies at the heart of the Universe itself.
