  Title The Light of the Night Sky Type (up) Book Whole
  Year 1973 Publication Abbreviated Journal  
  Volume Issue Pages  
  Keywords Natural Sky Brightness; Airglow  
  Abstract Astronomy appears to us as a combination of art, science, and philosophy. Its study puts the universe into perspective, giving a sense of pleasure in its beauty, awe at its immensity, and humility at our trivial place in it. From earliest human history, man has scrutinized the night sky – and wondered and marveled. With unaided eye but perceptive mind, he recognized order in the regular appearance and movements of individual objects, such as the planets and star groups (constellations), in their rhythmic and majestic progressions across the bowl of night. Even in the present era of scientific exactitude, there remains a profound awareness of mysteries beyond our present interpretations. It is only in comparatively recent years, however, that man has recognized that it takes more than conventional astronomy to account for the beauties ofthe night sky. Radiations in the Earth's upper atmosphere provide a foreground light, the study of which has come under a new name, aeronomy. The science of aeronomy has rapidly burgeoned, and the student of the light of the night sky finds that he is involved in an interdisciplinary domain. The 'meat' of one discipline, however, may be the 'poison' of the other. To the astronomer, the Earth's atmosphere, inhibiting his extra-terrestrial viewing, is a serious nuisance. To the aeronomer, the Moon, planets, stars, and Galaxies hamper his measurements and interfere with his studies of the Earth's upper atmosphere. Yet both sets of elements are basic to the beauties as well as to the understanding of the light of the night sky. It is essentially the students of astronomy and aeronomy for whom we have written this book. We also hope, however, that it will present much of interest and value to the bemused sky watcher, for whom some detailed knowledge of the several con-tried to meld these dual objectives to create a broadly based, professionally valid tributors to the nighttinie sky may increase his pleasure in contemplating it. We have treatise that will lead the serious student to deeper probing into the phenomena and will inspire both him and the enthusiastic amateur to an appreciation of that half of their experience which we may refer to as their 'night life'.

  Title How much Light do you get? Estimating Daily Light Exposure using Smartphones Type (up) Conference Article
  Year 2014 Publication Proceedings of the 2014 ACM International Symposium on Wearable Computers Abbreviated Journal Proc. of the 2014 ACM International Symposium on Wearable Computers  
  Volume n/a Issue n/a Pages 43-46  
  Keywords Instrumentation; light exposure; context inference, light intensity; light intake; circadian clock; circadian rhythm; mobile sensing  
  Abstract We present an approach to estimate a persons light exposure using smartphones. We used web-sourced weather reports combined with smartphone light sensor data, time of day, and indoor/outdoor information, to estimate illuminance around the user throughout a day. Since light dominates every human’s circadian rhythm and influences the sleep-wake cycle, we developed a smartphone-based system that does not re- quire additional sensors for illuminance estimation. To evaluate our approach, we conducted a free-living study with 12 users, each carrying a smartphone, a head-mounted light reference sensor, and a wrist-worn light sensing device for six consecutive days. Estimated light values were compared to the head-mounted reference, the wrist-worn device and a mean value estimate. Our results show that illuminance could be estimated at less than 20% error for all study participants, outperforming the wrist-worn device. In 9 out of 12 participants the estimation deviated less than 10% from the reference measurements.
