My work here
[edit]I first came on here to edit on April 28, 2004 (19 years ago now!) It is an addicting idea to try to add to something much bigger than I could ever do. I am a little skeptical over the idea of freedom to change anything, but overall I'm very impressed by the quality of articles and I have faith good work is being done and I can add to it.
There are many quality websites out there and it seems silly to duplicate too much. I like the idea of learning about something and testing my knowledge by trying to share it. For me that motivates much of my efforts here.
Primary topics I've worked on include geometry, and astronomy.
My specialty has primarily been image generation, perhaps because I've found so many articles where useful images were absent. I try to make quality images, but I will compromise perfection for meaningful improvement. I'm happy if anyone can replace my images with better ones.

[edit]- [3] Jimmy Wales is founder of Wikipedia, the self-organizing, self-correcting, ever-expanding, and thoroughly addictive encyclopedia of the future. In this presentation, he explains how Wikipedia's collaborative system works, and why it succeeds. (Recorded July 2005 in Oxford, UK. Duration: 20:47)

The Double Asteroid Redirection Test (DART) was a NASA space mission aimed at testing a method of planetary defense against near-Earth objects. The target object, Dimorphos, is a 160-meter-long (525-foot) minor-planet moon of the asteroid Didymos. DART was launched on 24 November 2021 and successfully collided with Dimorphos on 26 September 2022 while about 11 million kilometers (6.8 million miles) from Earth. The collision shortened Dimorphos's orbit by 32 minutes and was mostly achieved by the momentum transfer associated with the recoil of the ejected debris, which was larger than the impact. This video is a timelapse of DART's final five and a half minutes before impacting Dimorphos, and was compiled from photographs captured by the Didymos Reconnaissance and Asteroid Camera for Optical navigation (DRACO), the spacecraft's 20-centimeter-aperture (7.9-inch) camera, and transmitted to Earth in real time. The replay is ten times faster than reality, except for the last six images, which are shown at the same rate at which the spacecraft returned them. Both Didymos and Dimorphos are visible at the start of the video, and the final frame shows a patch of Dimorphos's surface 16 meters (51 feet) across. DART's impact occurred during transmission of the final image, resulting in a partial frame.Video credit: NASA / Johns Hopkins APL
