Are planks and rope now obsolete crop circle technology? Physicist Richard Taylor, director of the Materials Science Institute at the University of Oregon, posits that GPS, lasers, and handheld magnetrons may be the new tricks of the trade. He reports on his research in this month's issue of the journal Physics World. From the Institute of Physics:
Microwaves, Taylor suggests, could be used to make crop stalks fall over and cool in a horizontal position – a technique that could explain the speed and efficiency of the artists and the incredible detail that some crop circles exhibit.
Indeed, one research team claims to be able to reproduce the intricate damage inflicted on crops using a handheld magnetron, readily available from microwave ovens, and a 12 V battery.
As Taylor writes, “Crop-circle artists are not going to give up their secrets easily. This summer, unknown artists will venture into the countryside close to your homes and carry out their craft, safe in the knowledge that they are continuing the legacy of the most science-oriented art movement in history.”
Alex Wood is an addict but won’t give up his smartphone. But he has five strategies for limiting its control over him: “I used to wake up tired. My body would ache and my head felt sore, like waking up with a hangover. Finally, I took control, like attending an AA class for addicts, I […]
Ok, it’s not just solar powered. It’s also an anti-theft, waterproof marvel that keeps my phone’s power bar from ever getting into the red.Sure the idea seems obvious now – tuck a gigantic solar powered battery pack into an exposed slot and turn the wearer into a walking energy harvester. Simple maybe, but I didn’t […]
Maybe it’s entirely because of podcast ads, but drag-and-drop tools like Squarespace have gotten immensely popular in recent years. While it’s definitely a great tool for any non-coders who want to get a small website up and running quickly, managing content with a primarily visual interface can become a pain once you have more than […]
