What is true in medicine is equally true in physics. Concerning the debt of the inventor to the man of physical research, Mr. Addison Browne has this to say:-- Research in Physics and Chemistry. “A few weeks ago I was talking with an electrician who has made several very interesting and important inventions. I asked him of how much importance he conceived that the scientific men of the closet, the original investigators, so-called, had been in working out the great inventions of electricity during the last fifty years--telegraphs, cables, telephones, electric lighting, electric motors; and whether these achievements were not in reality due mainly to practical men, the inventors who knew what they were after, rather than to the men of science who rarely applied their work to practical use. He said, ‘The scientific men are of the utmost importance; everything that has been done has proceeded upon the basis of what they have previously discovered, and upon the principles and laws which they have laid down. Nowadays we never work at random--I go to my laboratory, study the application of the principles, facts and laws which the great scientists like Faraday, Thomson and Maxwell have worked out, and endeavor to find such devices as shall secure my aim.’ As Tyndall said, ‘Behind all our practical applications there is a region of intellectual action to which practical men have rarely contributed, but from which they draw all their supplies. Cut them off from that region and they become eventually helpless.’” Research is golden only when brought to fruit by co-operation. To quote Professor Tyndall:-- “To keep science in healthy play three classes of workers are necessary: (1) The investigators of natural truth, whose vocation it is to pursue that truth, and extent the field of discovery for its own sake, without reference to practical ends. (2) The teachers who diffuse this knowledge. (3) The appliers of these principles and truths to make them available to the needs, the comforts, or the luxuries, of life. These three classes ought to co-exist and interact.” Concerning the larger problems of engineering research, Professor Osborne Reynolds, of Owens College, Manchester, says:--
