Beauty has profound meaning in mathematics, at least to us.
Not sure you believe me? Well, a paper just published in the journal Frontiers in Human Neuroscience may just change your mind. Researchers use Functional Magnetic Resonance Imaging (fMRI) to map the brain activity of mathematicians as they viewed various mathematical formulae and constructions that they have rated on an ugly-beautiful scale. That part of the brain that is activated when people see beautiful art, or hear beautiful music (yes, there is a specific place)? Evidently, that place lights up when we view math that we see as beautiful. At least to us, it is real.
Give it a read (H/T to CG!!):
BTW, the most beautiful formula of the study: Why Euler's Identity, of course! Can you see the beauty?
