The Total Solar Eclipse of 1869 as Stimulus for Adoption of Physical-astronomy Techniques in the United States
Get PDFIn the United States, techniques that would one day be called astrophysical were applied later than elsewhere and comparatively suddenly. Their entry into US main-stream astronomy was motivated by a quasi-stochastic phenomenon: a total eclipse of the Sun visible between the contiguous borders of that country. In reaction to the upcoming event, the US Nautical Almanac Office in particular invested time, workforce, and a great deal of money into the measurements of physical astronomy, especially spectroscopy. This occurred although none of its employees had ever expressed—at least, in writing—expertise or even interest in the subject beforehand. Once adopted, physical astronomy, and the investigations it enabled, moved slowly, but steadily, into the mainstream of American astronomy despite objections from traditionalists. In the twenty-first century, spectroscopy and other physical astronomy techniques are essential tools for all astronomers

From Disruption to Integration: Cryptocurrency Prices, Financial Fluctuations, and Macroeconomy
Get PDFThis paper examines cryptocurrency shock transmission to financial markets and the macroeconomy using a Bayesian structural VAR with Pandemic Priors from 2015 to 2024. By affecting overall risk appetite, cryptocurrency price shocks generate positive financial market spillovers, accounting for 18% of equity and 27% of commodity price fluctuations. Real economic effects are significant in driving investment but remain limited, contributing only 4% to unemployment and 6% to industrial production variance. However, cryptocurrency shocks explain 18% of price-level forecast error variance at long horizons. Narrative analysis reveals sentiment and technology as primary shock drivers. These findings demonstrate cryptocurrency\u27s deep financial system integration with important inflation implications for monetary policy

Measurement and Analysis of Nitrogen Dioxide and Particulate Matter in Iowa
No full textThis study investigates air quality in Iowa by combining 20 years of satellite-based nitrogen dioxide (NO₂) data with real-world measurements of fine particulate matter (PM2.5). Using NASA’s Giovanni system, we compared annual average NO₂ maps from 2005 and 2024 and analyzed trends over two decades. Results show a clear decline in NO₂, especially in urban areas, likely due to cleaner technologies and regulations. In parallel, PM2.5 was measured using a MiniVol TAS Sampler and a portable Temtop air monitor. The highest PM2.5 level (151μg/m³) was recorded while driving on a gravel road near a crop field, far exceeding EPA health standards. Humidity also appeared to influence PM levels. Together, these findings show that while regional air quality has improved, local activities can still cause high short-term pollution events
