9/22/21    60 Free Film Noir Movies
   During the 1940s and 50s, Hollywood entered a “noir” period, producing riveting films based on hard-boiled fiction. These films were set in dark locations and shot in a black & white aesthetic that fit like a glove. Hardened men wore fedoras and forever smoked cigarettes. Women played the femme fatale role brilliantly. Love was the surest way to death. All of these elements figured into what Roger Ebert calls “the most American film genre” in his short Guide to Film Noir Genre. In this growing list, we gather together the noir films available online. They all appear in our big collection 4,000+ Free Movies Online: Great Classics, Indies, Noir, Westerns, Documentaries & More.

9/26/21    1800s Astronomical Drawings vs. NASA Images
   It's no secret that the New York Public Library's Digital Collections hold many, many treasures—over 690,000, to be more specific. Of all the gorgeous, funny, odd, and impressive items I've stumbled upon, the E. L. Trouvelot astronomical pastel drawings sit in my top ten. Trouvelot was a French immigrant to the US in the 1800s, and his job was to create sketches of astronomical observations at Harvard College's observatory. Building on this sketch work, Trouvelot decided to do large pastel drawings of "the celestial phenomena as they appear...through the great modern telescopes." What amazes me about these drawings is how detailed they seem to be—but I am no astronomer. I investigated further and paired them with NASA's photographs, taken about 150 years after Trouvelot's work, to see how precise his art was.
