GigaPan

Photographer David Bergman took this amazing photo at President Obama's inauguration with the GigaPan system. GigaPan uses a mechanical device called the Gigapan Epic plus an ordinary digital camera to take overlapping images (~220 in this case) and seamlessly stitch them together via special software to make one giant, high-resolution photo (this Obama inauguration photo apparently has 1.57 gigapixel resolution). On the GigaPan.org website it's possible to pan/zoom the photo to an amazing degree of detail. For instance, some ordinary people on the Mall will be able to identify themselves in this picture and show that they were there on January 20, 2009.

I believe the software which stitches the photos together involves fractal geometry technology similar to that which astronomers use to piece together images of the sky.

Bergman is selling prints of this photo here for ~$90+ and if I had been there I would deifintely buy one.

Forty Years

My wife Joy and I celebrated our 40 th wedding anniversary this past weekend with our children and grand-children. We were on lovely Sea Island, Georgia watching this spectacular sunrise and wondering how it was possible that forty years could have gone by so quickly. We had a lot of fun telling all the old stories about how we met, and courted, and married, and brought up the kids. Lots of laughs and a few tears as well. We've been through good times and bad together. We've both worked hard, had a few disappointments, but basically have accomplished mostly good things. We've had good health, loving families, good friends, three fine sons we're very proud of, wonderful daughter's-in-law who are perfect for our boys, and four of the best grandchildren ever. Life doesn't really get any better than that. We've really been blessed and we thank God for that. Now we're working to keep our health and live to celebrate forty more.

Barry Schwartz - The Paradox of Choice

MediaPost Publications - Americans Get More Channels, Watch Fewer Of Them, Especially Broadcast - 03/13/2006 Ironically, Barry Schwartz spoke at PC Forum last night about the Paradox of Choice, and what did I wake up to this morning. Another possible example of too much choice in the channels people have to choose from on television. I wonder whether the "a la carte" crowd has thought about this problem. I'll have to ask Prof. Schwartz about that today.
