Indigenous Astronomy As Told By The Haudenosaunee, Sasha Doxtator

2019 Cohort

Colonization has greatly reduced the extent to which Indigenous astronomy is presently known and shared. Much sky lore has become lost or fragmented, and the connections between stories, night sky observations, and their relevance is not as obvious as it once was. A detrimental spiral has ensued with many Western-trained scientists being reluctant to share sky lore out of fear of being misunderstood, disrespected, and dismissed.

Microgrid Technology And The Arctic: Green Renewable Technology Does Relate To The Land, Gerry Dell

2019 Cohort

Microgrids can take power from other energy sources and share their loads meaning there is a less reliance on diesel power generation. Wind mill power generators, solar power (for the summer) and battery storage are fantastic elements for providing consistent power in the Arctic. These power systems have been tried and proven, in all conditions, over many years. Geothermal is another green efficient way to heat homes and businesses in the Arctic. When I worked for Dome Petroleum in McKinley Bay NWT, I was fortunate to work in the most extreme winter weather the Arctic can produce. With global warming …

Synchrotron Radiation Analysis Of Daguerreotypes: Surface Characterization, Electrocleaning, And Preservation, Madalena S. Kozachuk

Electronic Thesis and Dissertation Repository

The first commercially viable photographic image, the daguerreotype, captured images from 1839 to 1860. While daguerreotypes provide a significant historical record of 19^th century individuals and events, deterioration now disfigures many of these images. This work describes the application of synchrotron radiation (SR) to the study of daguerreotypes.

Three goals were addressed in this thesis: 1) to utilize SR to further elucidate the physics and chemistry of the daguerreotype and how the surface varies with time, 2) to study the effects of the electrocleaning system on the daguerreotype surface, and 3) to propose suggestions to improve their preservation and …

Sympathetic Physics: The Keely Motor And The Laws Of Thermodynamics In Nineteenth-Century Culture, Robert Macdougall

History Publications

In Philadelphia in the 1870s, John Worrell Keely announced the invention of a fantastic new motor that could, he promised, drive locomotives, power factories, and even defy gravity without fuel or heat. The Keely Motor became the most notorious perpetual motion scheme of the nineteenth century, attracting believers and investors for nearly thirty years. This article explores the “work” the motor performed for Keely, his supporters, and his critics—not physical work, but financial, cultural, and psychological. To investors, the Keely Motor represented a dream of riches without effort. To Keely’s critics, the motor offered an opportunity to defend the legitimacy …
