—Dietz on Science— SCIENCE MARKS ‘VICTORY WEEK’ AT EXPOSITION World Convention Sees Greater Conquests for Future. BY DAVID DIETZ Serlppa-How ard Science Editor CHICAGO, June 28.— Last week was one of triumph for the world of science. In a setting provided by two great universities, the University of Chicago and Northwestern university, and with magnificent Century of Progress fair as a background, savants from two continents have reported victory after victory over problems which had previously baffled them for decadej, and, in some cases, centuries. Half a year ago, when the American Association for the Advancement of Science vas in session at Atlantic City, one had r.'ne feeling that the savants were a little bewildered by the wealth of experimental data that was accumulating in the field of physics, chemistry, and astronomy. At the present meeting of the same association, now in session here, one feels that in the last six months, scientists have found the path out of the tangle and that science is marching forward with rapid strides to greater and greater conquests. Forge New Branch Anew branch of science is being forged. It deals with the heart or the nucleus of the atom. Perhaps it will become known as nuclear physics or nuclear chemistry. It may be that both terms will come into use. Until the present meeting, the structure of the nucleus was a puzzle which became more complicated with each new discovery in the field of atomic physics. At the present meeting, it was demonstrated that all these discoveries fit into the simple theory of nuclear structure formulated by Dr. W. D. Harkins of the University of Chicago, a theory so simple, as Dr. Harkins himself puts it, that it required only “arithmetic and common sense.” His theory also explains the fact that each chemical element consists not of a single kind of atom but of a variety of atoms, chemically alike, but different in weight. Techincally, these ar.e known as isotopes. Shows Atom Has Nucleus Dr. Harkins showed*- that the lightest atom of each element has a nucleus composed of deutons or heavy hydrogen atoms, and that the isotopes are formed by the addition of one or more neutrons. Equally important advances were reported in other branches of sciences. Dr. A. V. Hill, famous British physiologist, told how with apparatus so delicate that it would measure a millionth of a degree of temperature, he had succeeded in measuring the heat produced when an impulse traveled over a nerve. Other savants, American physiologists who had received their training in Dr. Hill’s laboratory, told of experiments to measure the electrical and chemical changes which accompany nerve action. It was shown that the nerves recover and get ready for the next impulse by a process of breathing, absorbing oxygen and giving off carbon dioxide. Enumerate Accomplishments This work, it is expected, will lead eventually to an understanding of the processes which go on in the brain and link the outer w-orld of things with the inner world of consciousness. In the field of astronomy, new discoveries reported included the following: That oxygen in the atmosphere of Mars is sufficient to support life as we know it. That there is no such thing as empty space, a thin cloud of calcium extending everywhere. That within our own galaxy the amount of the stuff in the calcium cloud is equivalent to the amount concentrated in the stars. The recent measurements of distant spiral nebulae contribute additional evidence to support the theory that the universe is expanding like a gigantic soap bubble. Physical and biological science held the center of the stage at this week's meetings. Engineering and the social science will be the centers of interest at next week’s sessions here. GINGER ALE.
