| Salman Khan | Salman Khan operates the Khan Academy with hundreds, even thousands of video lectures on math, science, economics... |
| Don Lancaster | Don has PostScript info and lots of stuff about building various widgets. And debunking pseudoscience. |
| Brian Livingston | Brian has written many good books that help people with their problems with Microsoft Windows. |
| Bill Mason | Bill teaches (emeritus) aeronautical engineering at Virginia Tech and has many pages of detailed explanations of aeronautical topics. |
| Alan Miller | There is a treasure house of wonderful Fortran code at Alan Miller's web site. Try this mirror for now. |
| Ross Moore | Ross maintains latex2html, a program that I have used to create web pages that contain mathematical equations using GIF images for the equations. |
| PZ Myers | PZ teaches biology at U. Minn (Morris) and keeps the web site and blog called Pharyngula. |
| Jakob Nielsen | Jakob publishes a Web Usability guide at useit.com that is very helpful for web page designers |
| Stuart Norris | Stuart keeps lots of links to numerical methods, especially in Fortran. |
| Abimbola Olowofoyeku | Also known as The African Chief. A frequent contributor to programming newsgroups. His contributions are accurate and to the point. |
| Steve Pietrobon | Steve coded the equations for the upper atmosphere (>86km) that I used in the Standard Atmosphere section. |
| Jerry Pournelle | Jerry writes the Chaos Manor column for Dr. Dobbs magazine. |
| Michael Quinion | Michael writes the World Wide Words newsletter. |
| Dan Raymer | Dan has an interesting site relating to airplane design. When people ask me about books on aeronautics, I send them to Dan's book list. |
| James Randi | Randi is indeed Amazing. |
| Eric Raymond | Author of The Cathedral and the Bazaar and Homesteading the Noosphere |
| Timo Salmi | Timo was the moderator of Garbo and a frequent contributor to Pascal newsgroups. |
