  • Memorial Statements
    MEMORIAL STATEMENTS Cornell University Faculty 2019-2020 Office of the Dean of Faculty Ithaca, New York Editor Carrie Shugarts Copy Editor Jill Short 1 Preface The University Faculty has always followed the practice of including within the faculty records a memorial resolution on the death of one of its members. The faculty modified this custom that was begun in the earliest days of Cornell University in 1938 as follows: Upon the death of a member of the University Faculty, the President or Dean of Faculty shall formally notify the Faculty at the next meeting and those present shall rise in respect for the memory of the deceased member. The Provost shall then appoint a committee to prepare an appropriate memorial statement. Such statements shall not be presented in the form of resolutions, as in the past, but shall be annually collected, edited, and printed by the University in a memorial booklet, which shall be sent to members of the Faculty, to the families of the deceased members, and shall be filed with University records. This booklet, prepared by the Office of the Dean of the University Faculty, contains articles in memory of those twenty-five University Faculty members whose deaths were reported in the period from July 1, 2019 through June 30, 2020. The names of the committee members who prepared the statements are given at the end of each article. 2 Richard J. Archer June 8, 1948 – September 14, 2019 Professor Richard J. Archer was born on June 8, 1948 and died September 14, 2019 following a battle with cancer.

  • Carl Sagan: the People’S Astronomer by David Morrison, NASA, Ames Research Center
    Carl Sagan: The People’s Astronomer by David Morrison, NASA, Ames Research Center Introduction Carl Sagan was the world’s best known scientist in the late 20th century, serving as our guide to the planets during the golden age of solar system exploration. He was both a visionary and a committed defender of rational scientific thinking. For a time, he transcended the usual categories of academics to become a true celebrity. His life illustrates both the advantages (wealth, fame, access to the seats of power) and burdens (loss of privacy, stress, criticism from academic colleagues) this status implies. Sagan was propelled on his academic and public careers by a wealth of talent, a large share of good luck, and an intensely focused drive to succeed. His lifelong quest was to understand the universe, especially our planetary system, and to communicate the thrill of scientific discovery to others. A natural teacher, he loved to explain things and never made a questioner feel stupid for asking. Although Sagan had broad intellectual interests, his pursuit of his career left little time for other activities: he did not play golf or follow sports, take up painting or cooking or photography, sing or play a musical instrument, join a church or synagogue, or watch much television or movies. His first two wives complained that he devoted insufficient time to his marriage or his children (1). It is perhaps a matter of personal taste whether we attribute this drive to personal ego or a genuine commitment to educate and inspire people about science. Undoubtedly there were elements of both motivations present.

Biographical Memoir COPYRIGHT 2009 NATIONAL ACADEMY OF SCIENCES WASHINGTON, D.C. EDWIN E. SALPETER December 3, 1924–November 26, 2008 BY Y E R V A N T TERZIAN DWIN E. SALPETER WAS A TOWERING figure in 20th-century Eastrophysics. Among his major scientific accomplishments is his 1955 paper “The Luminosity Function and Stellar Evolu- tion,” where he first derived the empirical stellar initial mass function and estimated the probability for the creation of stars of given mass at a particular time, known as the Salpeter initial mass function. Just before this major achievement he had explained how giant stars burn helium to form carbon in the triple alpha process, where three helium nuclei combine to form carbon. This crucial step opened the path for the formation of elements as heavy as iron in the core of the stars. Salpeter showed the way to put physics into astronomy, and astrophysics has made enormous contributions to our understanding of the Universe. He once observed that most successful scientists are golf players, that is, they map out their own strategy and then write a unified theory. Salpeter said that he belonged to the minority of scientists who are Ping Pong players that react to influences from outside players. This approach made Salpeter a generalist. Salpeter was born in Vienna in December 1924 and attended elementary school there.

  • SCIENCE and TECHNOLOGY in ARMENIA Profiles of Armenian Scientists: World Class but Unknown Yervant Terzian with Lisa Natcharian
    SCIENCE AND TECHNOLOGY IN ARMENIA Profiles of Armenian Scientists: World Class but Unknown Yervant Terzian with Lisa Natcharian For decades, scientists in the Republic of Armenia have quietly made discover- ies that have had international impact but have generated little fanfare or recognition from the general public. Most Armenians are unaware of the world-class reputation these scientists enjoy, nor of the importance of the major Armenian research facilities that once powered the Soviet science effort. To begin sharing knowledge of these achievements with the wider Armenian community, profiles of three leading scientists are presented here. BENIK MARKARIAN Dr. Markarian was an astronomer with the Byurakan Astrophysical Observatory near Yerevan. A quiet man with far-reaching vision, he discovered a new class of galax- ies in the 1960's. A galaxy is a group of hundreds of billions of stars -- the galaxy of which we are a part is known as The Milky Way. There are many millions of other galax- ies in the visible universe, some of which have extremely bright cores or nuclei. Markar- ian identified and studies this type of galaxy during his lifetime, and in honor of his work, these galaxies bear his name -- the "Markarian Galaxies." Markarian galaxies have been shown to be some of the most active and ener- getic objects in the universe, and it is likely that these galaxies hide supermassive "black holes" in their cores. These black holes have enormous gravitational pull, and constantly devour other nearby stars by pulling them into the "black abyss." Such proc- esses create copious amounts of energy that then escapes from these galaxies and can be detected with telescopes on earth.

  • AO 50Th Address Yervant Terzian Cornell University October 2013 It
    AO 50th Address Yervant Terzian Cornell University October 2013 It was in early November 1964 that I first saw the magnificent Arecibo 300 meter radar/radio telescope. Thomas Gold, then Director of Cornell's Center for Radiophysics and Space Research, had invited me to visit the observatory, then named the Arecibo Ionospheric Observatory, in order for me to decide whether to accept an offer to be a research Associate at the observatory and use the telescope for radio astronomical research. I was completing my Ph.D. work at the National Radio Astronomy Observatory in Green Bank, West Virginia, where I had used the then new 300 ft transit radio telescope to study interstellar clouds and planetary nebulae. It was love at first sight so to speak, but much more so when my first observations of planetary nebulae with Arecibo resulted in easy detection of all targets and with high signal to noise ratios (Slide 1). All one needed was a few short sleeve shirts and lots of observing sources. Slide 1: Ring Nebula signal Even though at the time Arecibo functioned at low frequencies, the ingenuity of the electronics staff managed to make observations up to 611 MHz. Of course, the telescope visibility was restricted and my best sources were outside the visible cone. Yet again with no fear we built an extendable boom 32 ft long (Slides 2 & 3) and when attached at the edge of the paraxial structure one could see about five degrees extra in declination and thus observe at transit the giant Orion nebula at the south side and the Andromeda galaxy at the north side.

  • INTERGALACTIC NEUTRAL HYDROGEN Yervant Terzian NAIC
    INTERGALACTIC NEUTRAL HYDROGEN Yervant Terzian NAIC Cornell University Ithaca, New York 14853 U.S.A. Here I would like to report on the HI intergalactic cloud in the Leo group of galaxies, which was first announced in 1983 by Schneider, Helou, Salpeter and Terzian (1983). This unexpected discovery was made accidentally by S. Schneider while calibrating the Arecibo X21 cm system by looking at a part of the sky where no HI emission was expect­ ed at high velocities. These observations were made during a project of studying the HI distribution in binary galaxies and in small galaxy groups. The HI emission was found mainly in a region 100 kpc long by 30 kpc wide midway between the galaxies M96 and M105« Fainter emission, extending North and South of the main cloud spans about 200 kpc and reaches the vicinity of M96. Schneider (1985) has interpreted the observed emission and kinematic structure of this cloud as a giant HI ring with a lifetime of several billion years. Our original studies of this interesting HI cloud indicated high radial velocities of about 1000 km/s, which unambiguously distinguish this cloud from local high-velocity clouds. We also note that the isolation of the HI gas from the surrounding galaxies in Leo exceeds that of any previously studied HI feature in a group of galaxies. Also the lack of any optical tidal features to the nearby galaxies argues that this intergalactic cloud is not a recent tidal product. Further­ more, the mass of more than 2 x 10 MQ in neutral hydrogen represents a substantial fraction of all the HI in the M96 group of galaxies.
