I think that the beauty seen in science falls into four broad categories. First, a scientist may find beauty in their experimental system, whether it is a model organism, a certain diagnostic printout, or an aesthetically pleasing series of molecules.
Secondly, there is the cleverly devised experiment carried out with skill and patience that results in good clear data: the molecular biologist’s sharp DNA bands on a gel, the organic chemist’s high yield, or the physicist’s precise measurements.
Third, the data and the theory that gathers them into a coherent whole may have an intrinsic beauty that is both striking and satisfying. Physicists have appreciated beauty in symmetry, in order, and in complex systems that are reducible to a series of ‘elegant’ mathematical equations. Biological systems are more complex and difficult to describe mathematically, so the beauty observed in the life sciences is more often to do with colour, pattern, shape, movement, or detail. At times, complex biological systems are understood at a level that does reveal their mathematical simplicity. When order emerges out of apparent chaos biologists begin to use words like ‘striking’, ‘beautiful’, and ‘astonishing’. If a theory is developed that can be used to predict further experiments and explain other data, that is also beautiful in its own way. We appreciate the order, unity and simplicity that it brings to our understanding of the world. Continue reading
