Love has been a topic of debate for centuries. We know how it feels, how it comes about, what it makes us do—but what exactly is it and why does it make us feel this way?

Recently, I ran across an article by Forbes Magazine featuring one scientist, Andreas Bartels, who is seeking to answer these age-old questions. By mapping brain activities of members of 2 year relationships, Bartels hopes to find what parts of the brain are responsible for these feelings. Through science, he hopes to finally answer the questions surrounding love.
