World-renowned relationship expert John Gottman set forth to understand why relationships don’t work, but for that he needed to first understand relationships scientifically. Gottman then measured the behavior, perception and physiology of couples over time to understand how love works. With that he was able to create equations for love and discern the mathematical dynamics of love. His science was able to predict with a 90% accuracy whether relationships would last or not. Finally, his studies conclude that the magic of love requires calm and commitment, which in the end makes the magic of great love a bit less of a mystery.
