...that there must be a rare isotope of hydrogen mixed with the abundant common hydrogen found in water and sugar. Such an isotope would behave chemically like hydrogen, but weigh two, perhaps three times as much. Professor Raymond Thayer Birge of the University of California and Professor Donald Howard Menzel of Harvard calculated that one part of heavy hydrogen should appear in 4,500 parts of ordinary hydrogen...
Last week another scaffolding, moldy with age, was being pounded to splinters by Drs. Donald H. Menzel of Harvard Observatory and J. C. Boyce of Massachusetts Institute of Technology. Since 1869 the light of the sun's spectacular corona, trapped in spectroscopes during the scant seconds of a total eclipse, has produced on the spectrogram five mysterious bright lines. Astronomers deduced that the corona, though mostly scattered sunlight, was partly self-luminous. What element made it so? Not knowing, they called it "coronium." As recently as last year, in a standard work on eclipses, "coronium" was treated with respect...
...Daniel H. Menzel of the Harvard Observatory and Dr. Joseph C. Boyce of the Massachusetts Institute of Technology have at last succeeded in identifying the element responsible for the major part of the sun's coronal radiation, marking the first important step in unravelling a mystery dating from the first observations of the spectra of the corona more than sixty years...
...Menzel, who is an assistant professor of Astronomy at Harvard, and Dr. Boyce, research associate at M. I. T., studied together at Princeton and received their M. A. degrees in the same year, 1923. Professor Menzel obtained his Ph.D. the following year and Dr. Boyce in 1926. The former became associated with Harvard...
Tonight's lecture will be given at 7.30 o'clock and repeated at 9.30 o'clock by Dr. D. H. Menzel, noted authority on the atmosphere of the sun. Taking as his topic "The Puzzle of the Planets," he will expound, among other things, the secret of the canals on Mars and the possibility of life there, the frozen clouds of Jupiter, and the rings of Saturn. He will also discuss the discovery of Pluto, and the speculations it has incited as to the number of planets and the boundary of the sun's domain...
