This month I’ll be traveling to Maker Faires in Portland, Oregon, and New York City to sign and talk about my book, The Annotated Build It Yourself Science Laboratory. That, of course, is the new, updated version of Build-It-Yourself Science Laboratory, the classic 1960’s hands-on science book by Raymond E. Barrett.
The Portland Mini Maker Faire is being held September 12-13 at OMSI, the Oregon Museum of Science and Industry. I’ll be speaking on the Innovation stage at 11 AM on September 12. This is a bit of a homecoming for the book: Raymond Barrett was the Education Director at OMSI when he originally wrote the book.
Biosphere 2 is an enormous earth science laboratory, originally built as an attempt to create a closed ecosystem. The goals were to study long term viability of an isolated human habitat, such as might be needed for long term space travel or colonization.
The results of the initial experiments were a (fascinating) mixed bag. The goal of a strictly closed ecosystem was not met for a variety of reasons. However, some of the results have improved our understanding of the effects of climate change, such as how increased CO2 levels lead to acidification of the ocean habitat and coral bleaching.
The facility is now being used both for education and for research. The enormous agricultural greenhouses have been transformed by the University of Arizona into the Landscape Evolutionary Observatory, a large-scale carefully-controlled long-term study of soil processes. It serves as an experimental bridge between computer models, small-scale laboratory experiments, and the real world.
Some of the original biomes are relatively unchanged and have been growing since the project started in 1991. It is striking to have all hint of surrounding desert obscured by the vines of the rainforest.
One of the most fascinating engineering aspects of the facility are the “lungs,” which are accessed through long narrow tunnels branching off of the main facility.
The lungs were used to compensate for the changes in pressure and temperature. The two domed buildings have flexible inner liners that can expand and contract. A weight attached to the center of the liner makes them look toroidal inside of the dome.
The facility was built outside of Tucson, and is strikingly beautiful, surrounded by wildlife including lizards, snakes, tarantulas, jack rabbits, coyotes, gila monsters, and an incredible variety of birds and insects. We’ve put a few more pictures from our visit in albums on flickr here and here. Tours are available to the public daily, and it’s worth the drive and ticket price if you’re nearby.
I took a heap of pictures at the 2nd annual Silicon Valley STEAM Festival at the Reid Hillview Airport in San Jose today. This event brings out an eclectic mix of hobbyists, scientists, and enthusiasts showing off what they do. Below are a few of my favorite moments.
The local RC aircraft enthusiasts not only displayed their aircraft, but also put on an airshow. They also fly at Baylands Park, and encouraged coming to see them on Sundays.
Super Awesome Sylvia has posted a video report from this year’s RoboGames. Highlights include a couple of combat matches, one of Sylvia’s LEGO competitions, WaterColorBot receiving a medal, and Sylvia completely geeking out after Grant Imahara interviewed her in the audience. (For extra fun, watch the raw footage of the interview from RoboGames.) Our STEAM shirt makes a cameo, too.
