"These vegetables are part of our common cultural heritage, and our goal is to make sure these seeds remain in the public domain for people to use in the future," says UW-Madison horticulture professor and plant breeder Irwin Goldman, who helped write the pledge.
Goldman will release two carrot varieties he developed-named Sovereign and Oranje in the spirit of the event-at a public ceremony Thursday's public ceremony, which is set for 11 a.m. on the front lawn of the UW-Madison's Microbial Sciences Building, 1550 Linden Drive.
The Open Source Seed Initiative (OSSI) was established in 2011 by public plant breeders, farmers, non-governmental organization staff and sustainable food systems advocates from around the nation concerned about the decreasing availability of plant germplasm-seeds-for public plant breeders and farmer-breeders to work with.
Many air pollution monitors require a long optical path for making accurate measurements. This usually dictates large fixed instruments that sometimes resort to folding optics like Herriott cells.
NASA has come up with a clever way to make a physically small but optically long path using a cylindrical cavity that could be precsion machined in an aluminum billet. A varity of pollution monitoring tools could be inexpensive and potentially accurate. This kind of precision maching isn't cheap, but Apple has the manufacturing chops to make these cavities at scale. Not that they'd do it, but it would make a wonderful addition to their phones and pads - imagine if every edu iPad came with one. The density of pollution measurements would could improve by several orders of magnitude.
Bicycle component maker SRAM has developed a 3 speed hub that should be very robust and well suited to remote villages that lack specialized bicycle repair shops. An interesting feature is a power take off so a mechanical contraption can more easily use human supplied power - anything you can hook a chain to that is under a few hundred watts of mechanical power.
About 85,000 Buffalo bikes from World Bike Relief have been distributed Africa. The price is a bit over $130 per bicycle.
I listened to the podcast from To the Best of Our Knowledge during an exercise session and pass on an episode on the better-abled. When the disabled go beyond what is expected of a normally-abled person. mp3 and online listening here. 2, on offering help may be useful. 3 is a remarkable piece and makes me think of a deaf friend and her enhanced vision.
A googol is 10100 - 101 digits the inspiration for a mispelling that names a search company and sometimes taught to kids as a really big number. Beyond that is 10googol - the googolplex with about 17 million digits. But this is tiny - very tiny - compared with the scale of Graham's Number:
