How can the physics and engineering of wind and water change a country? From the world of European travel guides, here’s a quick primer: The Netherlands: Working Windmills.
300 years ago, half of what we know as The Netherlands was under water. Slowly, the former seabed was reclaimed and the Dutch went to work drying the ground with the country’s leading natural resource - the wind. Over 1000 windmills, some still functioning, survive in the Netherlands today, reminding locals and tourists alike of the clever engine that powered the creation of this land.

Watch Ferrari’s F1 pit crew do a pit stop in around two seconds. We had to watch this multiple times so that we could figure out what each crew member’s two second task was and how they were doing it so quickly. Pretty incredible. From Autosport.com, via Kottke:
With three people per wheel, two jack operators, and a handful of mechanics fulfilling other functions, each pit crew comprises nearly 20 people…
They are drilled incessantly at both the factory and during race weekends, with hundreds of pitstop practices until the process is instinctive.

From KQED Science, find out how San Francisco’s 600 tons of compostable waste can be transformed into a dark, nutrient-rich material that will not only feed plants to improve the quality of what we eat and drink, but that also has the potential to offset America’s carbon emissions by over 20%. Above, agronomist Bob Shaffer takes us Inside the Compost Cycle.
Food scraps, mostly compostable, are over 30% of everyone’s garbage, and could instead help turn poor dirt into nutrient-rich soil where you live. If you’re interested in learning how to compost, check out these excellent links:
