The CENTENNIA Historical Atlas

About Frank Reed, Creator of Centennia :

• Head Cartographer, Centennia Historical Atlas
  I'm the creator and curator of the Centennia Historical Atlas. All of the maps, apps, software, and animation are my creative work. The Centennia Atlas was, for over fifteen years, required course material for all students at the US Naval Academy at Annapolis, MD. Please visit HistoricalAtlas.com to learn more. My youtube channel has over 1.2 million views. Other videos, generally copyright-violating, based on my map animations have accumulated over fifteen million hits.
• ReedNavigation.com
  I also teach all of the workshops in celestial navigation presently offered by ReedNavigation.com, including all online workshops. I am fluent in nearly every technique and tool in celestial navigation from ancient historical methods to the most modern computer-based applications, and I am the world's leading expert in the topic of lunars.
• StarTalk television: Celestial Navigation Expert
  I was recently a guest, aboard as an expert in celestial navigation, on StarTalk, a science talk-show hosted by Neil deGrasse Tyson available on various streaming services (look for S4 E10). Dava Sobel, author of "Longitude" also joined us in the studio for one segment. Also available as audio-only (free).
  

  

  
• Developer, GPS Anti Spoof apps for Android and iOS
  My "GPS Anti Spoof" app has been released for iOS and Android. The app does everything. Shoot the Sun (or Moon, planet, star) with your sextant and directly compare with the displayed altitude in the app. No calculations / no paperwork. It's great for sextant training --you get instant feedback. And it easily detects GPS spoofing, if you're worried about pirates and that sort of thing! Unlike nearly all other available apps and software, this app also incorporates the deflection of the vertical, which can throw off your sights by more than one minute of arc near many islands. The app is dead-on accurate. Details and download links: ReedNavigation.com/GPSantiSpoof/.
• Gravitation and Physics
  I am an expert in gravitational physics including topics ranging from theoretical general relativity to practical tidal analysis. My thesis at Wesleyan University (Middletown, CT, 1984) was awarded High Honors, and I was also the winner of the Sherman Prize in Mathematics and the Bertman Prize in Physics. Read an article about me from Physics World magazine in their Once a Physicist column.
• StarTalk Radio
  In addition to appearing recently on StarTalk television, I was a guest on Neil deGrasse Tyson's StarTalkRadio: StarTalkRadio: Time Lords and the Science of Keeping Time (to listen to my contributions, go to time stamps 12:09-14:50 and 24:20-25:35). Here's a gallery of the participants.
• Interview on NPR's "Here and Now"
