Below are just a few of the articles I have researched and written, primarily recent ones that support my major long-term research on history of 19th-century U.S. astronomy, and energy/environmental concerns. A sampling of ones on current science and engineering and adventure travel are at bottom. For articles on the 1913 flood and its relevance today, see the next web page dedicated to that disaster.

Editors: If a print magazine or newspaper has also published an article online, I have included a link directly to the PDF or HTML (about two-thirds of the articles). Roll your mouse over the thumbnails of the print magazine or newspaper pages; those with links should turn your cursor into a hand. Depending on your browser, the article pages with links may also appear outlined in color. In some browsers, hovering over an image with your mouse may reveal hidden type giving publication details about the article. For profiles of prominent scientists/engineers and their work, or articles on travel, adventure, bicycling, or nature, or if there is a problem with a link, please contact me directly to request a PDF. I can also supply a complete list of my publications.


History of astronomy, both popular and academic, from original archival research (I've been continuing research in 19th-century U.S. observatories and telescopes since college and graduate school):

                                                                                                                                                      

also have written encyclopedia entries (ranging from 600 to 5,000+ words) published in the first and second editions of the Biographical Encyclopedia of Astronomers (Springer, 2007 and 2014, on seven astronomers); Dictionary of Nineteeth-Century British Scientists (Thoemmes Continuum, 2004, on six astronomers); Encyclopedia Americana (grolier's 2005, major entries on atmospheric optics, bicycling, and occultations); Oxford Encyclopedia of American Science, Medicine, & Technology (Oxford University Press, 2015, major entry on astronomy and astrophysics); editors, contact me for PDFs



Articles about current astronomy, computational astrophysics, or current instrumentation:

                                                                                                                                                                                     



Articles about energy, infrastructure, or climate change:

                                                                              


Weather, atmospheric phenomena, and eyeball astronomy:

                                          
 
also wrote lengthy (5,600 words) encyclopedia entry "Atmospheric Optics" for Encyclopedia Americana, 2005
