...subjects of the six lectures are as follows: 1. "Study of Starlight: brightness, colors, spectra"; 2. "Temperatures, Dimensions, and Masses of the Stars: relations between mass and luminosity"; 3. "Variable and Temporary Stars: relation between period and luminosity"; 4. "Interpretation of Stellar Spectra: ionization and consequences, stellar atmospheres"; 5. "The Same, continued"; 6. "The Interior of a Star: problems of constitution and Evolution...
Toward Emptiness. Many physicists are talking today about an expanding universe. The "red shift" observed in starlight has been interpreted by some to demonstrate that the stars of the universe are rushing away from each other like a panic-stricken crowd (TIME, Oct. 6, Jan. 5). Last week Dr. Albert Einstein told newsgatherers in Pasadena that he was anxious to talk to Mt. Wilson astronomers about their observations of the red shift. At the same time in Cleveland, Dr. Harlow Shapley, director of Harvard Astronomical Observatory, reported some data about the expanding universe which he expects to repeat later...
...finite universe is dependent upon matter. Abbé Lemaître, Belgian mathematician, investigated Einstein's universe, found that it would be unstable, would necessarily either expand to infinity or contract to a point. Immediately astronomers looked at the stars, measured the amount of spectral shift in starlight (the Doppler effect). They found most starlight shifted towards the red end of the spectrum, interpreted it to mean movement away from the earth (TIME, Oct. 6), concluded that material bodies were spreading, expanding universal boundaries. Dr. Fritz Zwicky of California Institute of Technology and Dr. P. ten Brieggencate, Dutch astronomer...
...second in the series of Open Nights at the Harvard College Observatory which are being held under the auspices of the Bond Astronomical Club will be held this evening at 7.30 o'clock. The speaker will be Professor E. S. King, who will speak on the subject "Measuring Starlight...
Titles of the talks to be given at 7.30 o'clock on the various open nights are as follows: Friday, October 17, "Pluto and Eros" by Professor Anne S. Young of Mt. Holyoke College; Tuesday, October 21, "Measuring Starlight" by Professor E. S. King; Thursday, October 23, "Something about Comets" by Leon Campbell; Tuesday, October 28, "More About Nebulae" by Miss Adelaide Ames; Thursday, October 30, "The Interior of a Star" by Professor H. H. Plaskett. The last four speakers are connected with the observatory. The open nights are being held under the auspices of the Bond Astronomical Club...
