History Committee Report NC185: Robotic Telescope— Page | 1 Suggested Celestial Targets with Historical Canadian Resonance
RASC History Committee Report NC185: Robotic Telescope— Page | 1 Suggested Celestial Targets with Historical Canadian Resonance 2018 September 16 Robotic Telescope—Suggested Celestial Targets with Historical Canadian Resonance ABSTRACT: At the request of the Society’s Robotic Telescope Team, the RASC History Committee has compiled a list of over thirty (30) suggested targets for imaging with the RC Optical System (Ritchey- Chrétien f/9 0.4-metre class, with auxiliary wide-field capabilities), chosen from mainly “deep sky objects Page | 2 which are significant in that they are linked to specific events or people who were noteworthy in the 150 years of Canadian history”. In each numbered section the information is arranged by type of object, with specific targets suggested, the name or names of the astronomers (in bold) the RASC Robotic Telescope image is intended to honour, and references to select relevant supporting literature. The emphasis throughout is on Canadian astronomers (in a generous sense), and RASC connections. NOTE: The nature of Canadian observational astronomy over most of that time changed slowly, but change it did, and the accepted celestial targets, instrumental capabilities, and recording methods are frequently different now than they were in 1868, 1918, or 1968, and those differences can startle those with modern expectations looking for analogues to present/contemporary practice. The following list attempts to balance those expectations, as well as the commemoration of professionals and amateurs from our past. 1. OBJECT: Detail of lunar terminator (any feature). ACKNOWLEDGES: 18th-19th century practical astronomy (astronomy of place & time), the practitioners of which used lunar observation (shooting lunars) to determine longitude. -

107 V Ariations on the Unexpected
107 Variations on the Unexpected SURPRISE 107 Variations on the Unexpected Dedication and Prelude To Raine Daston In his essay “Of Travel,” Francis Bacon recommends that diaries be used to register the things “to be seen and observed.” Upon returning home, the traveler should not entirely leave the visited countries, but maintain a correspondence with those she met, and let her experi- ence appear in discourse rather than in “apparel or gesture.” Your itineraries through a vast expanse of the globe of knowledge seem to illustrate Bacon’s recommendations, and have inspired many to em- bark on the exploration of other regions—some adjacent, some dis- tant from the ones you began to clear. Yet not all have journeyed as well equipped as you with notebooks, nor assembled them into a trove apt to become, as Bacon put it, “a good key” to inquiry. As you begin new travels, you may add the present collection to yours, and adopt the individual booklets as amicable companions on the plane or the U-Bahn. Upon wishing you, on behalf of all its contributors, Gute Reise! and Bon voyage!, let us tell you something about its gen- esis and intention. Science depends on the unexpected. Yet surprise and its role in the process of scientific knowledge-making has hitherto received lit- tle attention, let alone systematic investigation. If such a study ex- isted, it would no doubt have been produced in your Department at the Max Planck Institute for the History of Science. The topic is a seamless match with your interest in examining ideals and practices of scientific and cultural rationality—ideals and practices often so fundamental that they appear to transcend history or are overlooked altogether. -

The Pre-Embryonic State of the AAVSO
154 Saladyga, JAAVSO Volume 27, 1999 THE “PRE-EMBRYONIC” STATE OF THE AAVSO: AMATEUR OBSERVERS OF VARIABLE STARS IN THE UNITED STATES FROM 1875 TO 1911 Michael Saladyga AAVSO Headquarters 25 Birch Street Cambridge, MA 02138 Presented at the 87th Annual Meeting of the AAVSO, October 31, 1998 Abstract For 35 years before the formation of the AAVSO, independent amateur variable star astronomers in the United States were making significant contributions to the field. Skilled, dedicated individuals like S. C. Chandler, E. F. Sawyer, and P. S. Yendell laid the foundation in variable star work that was expanded upon by Harvard College Observatory Director E. C. Pickering, under whose direction a new generation of enthusiastic amateur and professional astronomers continued to further the cause of variable star research. This paper is a survey of the contributions made by several independent amateur variable star astronomers, and it is also a chronology of the growth of a broader, more popularized, amateur involvement in variable star astronomy which led to the organization of the AAVSO in 1911. 1. Introduction The German astronomer Friedrich Argelander is well-known in variable star histories as the “father of variable star observing.” The professional astronomer Argelander in 1844 first brought to the attention of the astronomical community the phenomena of variable stars and the need for observations of them. His Uranometria Nova catalogue of the magnitudes of over 3,500 northern stars was a great boost to the involvement of amateur observers of variable stars in Europe. This catalogue was not widely available in America, hence the late start here in amateur variable star work. -

Biographical Memoir COPYRIGHT 1995 NATIONAL ACADEMIES PRESS WASHINGTON D.C. SETH CARLO CHANDLER, JR. September 16, 1846–December 31, 1913 BY W. E. CARTER AND M. S. CARTER ETH CARLO CHANDLER, JR., IS best remembered for his re- Ssearch on the variation of latitude (i.e., the complex wobble of the Earth on its axis of rotation, now referred to as polar motion). His studies of the subject spanned nearly three decades. He published more than twenty-five techni- cal papers characterizing the many facets of the phenom- enon, including the two component 14-month (now referred to as the Chandler motion) and annual model most gener- ally accepted today, multiple frequency models, variation of the frequency of the 14-month component, ellipticity of the annual component, and secular motion of the pole. His interests were much wider than this single subject, however, and he made substantial contributions to such diverse areas of astronomy as cataloging and monitoring variable stars, the independent discovery of the nova T Coronae, improv- ing the estimate of the constant of aberration, and comput- ing the orbital parameters of minor planets and comets. His publications totaled more than 200. Chandler’s achievements were well recognized by his con- temporaries, as documented by the many prestigious awards he received: honorary doctor of law degree, DePauw Uni- versity; recipient of the Gold Medal and foreign associate of the Royal Astronomical Society of London; life member 45 46 BIOGRAPHICAL MEMOIRS of the Astronomische Gesellschaft; recipient of the Watson Medal and fellow, American Association for the Advance- ment of Science; and fellow, American Academy of Arts and Sciences. -

(Received March 26, 1990) ABSTRACT We describe the construction and evolution of a large amateur-built radiotelescope over the past 14 years. To illustrate the improvements in sensitivity achieved during the project, we include examples of observations made with the instrument. RÉSUMÉ Nous décrivons la construction et 1'évolution d'un grand radiotéIescope fabriqué par des amateurs pendant les 14 dernières années. Pour illustrer les améliorations de la sensibility réalisées pendant ce projet, nous incluons des exemples d'observations effectuées avec cet instrument. Introduction. Technical progress is bringing the construction of highly sensitive radiotelescopes within the reach of private individuals. Amateur radioastronomers need no longer be limited to making observations of the Sun, Milky Way and the four strongest discrete radio sources. Components, which only a few years ago could be found only in large research facilities, can now be bought over-the-counter. However, building the large antennas and sensitive receivers, and the signal processing needed for some of the more ambitious projects, such as detecting quasars and other faint radio sources, may require the resources of a group. -
Radio Astronomy
RADIO ASTRONOMY Astronomy began when people first recognized patterns of stars in the sky. Radio’s first beginnings were in 600 B.C. A Greek philosopher named Thales [S2] discovered that amber accumulates a charge by rubbing it with fur. The charged amber can then attract light objects. If Thales rubbed the amber long enough, he could even get a spark to jump. The Greek root of amber evolved into the word “electricity.” In 1600, William Gilbert took the word “electrum,” or “amber,” and formed it into “electrica,” referring to substances which attract. In 1646 the actual word “electricity’ appeared in Thomas Browne’s huge encyclopedia, Pseudodoxia Expedemica. Then in the 1820s, an Englishman named Michael Faraday [S3] discovered a relationship between light and electromagnetism. He went on to become the founder of the electromagnetic theory of light. A little trivia here: Faraday had very little formal education. He didn’t know much about higher mathematics, such as calculus. Yet he was one of the most influential scientists of all time. Some science historians call him the best experimentalist in history. Albert Einstein kept his photograph on his study wall beside pictures of Isaac Newton and James Clerk Maxwell. [S4] Maxwell was a Scotch mathematician who published a book based Faraday’s theories in 1873. He proved mathematically that Faraday’s conceptions were accurate. He also proved the astounding fact that electric and magnetic phenomena were identical with light. He theorized that all these phenomena could be reduced to motion in the form of waves in a substance he called the “aether,” a sparse and transparent fluid believed to fill all space.
