Bill Nye's Marsdial
Some Clown writes "MSNBC via the Seattle Post Intelligencer is reporting that Bill Nye the Science Guy, as part of the Earthdial Project has got what's being billed as a 'Marsdial' put onto the Mars Rover. Interestingly, it is now the official backup for orienting the Mars Rover in case of primary camera failure. Maybe an old fashioned sundial is just what the doctor ordered after the many math and other blunders of late. This whole Earthdial Project seems pretty interesting as well. They're trying to set up a worldwide network of sundials tracked via webcam. The goal is to track the sun's movements as viewed from many points on earth, as well as from Mars. Definitely interesting... at least if the 'Marsdial' doesn't disintegrate upon landing." There's a little more technical description of the Marsdial in our earlier story.
I have noticed that the Beagle 2 may have a problem with its clock:
Another possibility is that Beagle's clock might have been reset during its descent to the Martian surface, and so it is trying to call home when nobody is listening.
Now this potential problem has a solution! The rovers just need to use the Marsdial to calibrate their clocks on landing.
Ask me about repetitive DNA
One time, he even came to the elementary school I went to and gave a presentation on precipitation and weather patterns. It was actually one of the most entertaining presentations I ever saw at school. I havn't heard anything about what he has been up to in years, but I'm glad to see that he is still actively contributing to the world, and perhaps continuing to interest kids with his wierd experiments.
I wonder (thinking of all these angles of observation), if given observation points on multiple planets, if you would get an actual "3d" representation of the local universe.. or if the distances involved would require the observation points to be further apart.

during the last daylight savings time switch i actually went and read a bit about it. what i found particularly interesting were some details behind the creation of standard time:
"Standard time in time zones was instituted in the U.S. and Canada by the railroads on 18 November 1883. Before then, time of day was a local matter, and most cities and towns used some form of local solar time, maintained by some well-known clock (for example, on a church steeple or in a jeweler's window). The new standard time system was not immediately embraced by all, however.
[SNIPPED]
Detroit kept local time until 1900 when the City Council decreed that clocks should be put back twenty-eight minutes to Central Standard Time. Half the city obeyed, half refused. After considerable debate, the decision was rescinded and the city reverted to Sun time. A derisive offer to erect a sundial in front of the city hall was referred to the Committee on Sewers. Then, in 1905, Central time was adopted by city vote."
the notion of living according to local solar time is very appealing to me. i wonder how my natural rhythms might be different from what they are now and how i would feel if i lived more in harmony with the ebb and flow of light.
it's interesting to note that *when* plants and animals receive sunlight has a huge effect on their existence. not only that, the whole environment the plant or animal exists in changes with the arrival of sunlight (other critters wake up, temperatures rise, moisture levels change, etc.). the whole biology is mind-bogglingly complex.
it seems to me that standardizing time adds more complexity to an already complex system that already works fine without the notion of _time_. i also notice that the desire for knowing the answer to "what time is it?" is deeply rooted in a desire for control.
human attempts to control biological systems has seemingly contributed to a vast destabilizing of our environment everywhere on earth. moving back to true local solar time seems like something that might move us back in the direction of our natural rhythms and encourage us to relinquish the notion of needing to control.
on Christmas Eve i decided to have a potluck with my friends. i told them all to bring candles because i wanted to turn of the electricity while we ate. this was partially inspired by some of my friends that have instituted "no-electricity sundays" in their home. every sunday (for the whole day) of every week they turn the juice off at the breaker box.
after everyone arrived i lit all the candles, but i left some of the lights on. i was concerned that there would not be enough light. after the potluck ended i realized that being accustomed to having daytime quantities of light available at night led me to choose to leave electric lights on. realizing this led me to dine by candlelight (with even fewer candles) for my Christmas dinner. the dimness of the candle light made me much more aware that it was the evening. it also caused me to reflect on the sustainability of using electricity and contemplate how i might use less of it.
