How William Henry Bragg might approach Biology
Let us consider the evidence. When I speak of biology, I do not speak of a separate realm, but of a particular and intricate application of physics and chemistry. The living organism is, after all, a structure of matter, and its every function is dictated by that structure. It is a matter of observation and measurement.
Consider the simple act of a muscle contracting. We can observe the macroscopic result, but the true explanation lies in the arrangement of protein filaments, in the sliding of one set of molecules past another. The structure, you see, dictates the function. My own work with X-rays has shown us that we can, by careful experiment, determine the positions of atoms within a crystal. Why should the same principle not apply to the fibres of a muscle, or the helical coils of a protein? It is a matter of scale and patience, not of principle.
We must seek the underlying laws. A biologist might describe the behaviour of a cell, but the physicist must ask *why*. What forces hold its membrane together? What are the precise angles of the bonds in the DNA molecule that allow it to replicate? A simple analogy might help clarify this: a great cathedral is not merely a collection of stones; it is a structure whose every arch and buttress obeys the laws of mechanics. So too, a living organism is a structure obeying the laws of physics. To understand life fully, we must first understand the architecture of its constituent parts. The practical utility of this knowledge is immense, for in understanding the structure of a disease-causing virus, we may find the means to disrupt it. That is the true path of science.
