An example of an analogy used by a scientists to explain a scientific idea:
"The work of the physico-chemists, particularly of Svedberg, has shown that active proteins exist in the form of molecules of definite molecular weight, and more recently x-ray structure analysis has shown that they are perfectly definite chemical compounds with identical molecules which persist unchanged through various grades of crystal hydration and into solution. We possess already much information as to the actual molecular arrangement, but unfortunately its full interpretation is a task for the future. The situation at the moment is extremely similar to that of an archaeological expedition that has discovered large quantities of rock inscriptions in an unreadable script. They may not know what the inscriptions mean, but they do know they mean something, and they may reasonably hope to decipher them."
J. D. Bernal (1951) The Physical Basis of Life, Routledge and Kegan Paul
