Apparently a high percentage of chefs at Chinese restaurants suffer shoulder plane from wok tossing. They must rapidly move the heavy pan to launch the food into the air so it cooks but doesn’t burn, even though the temperatures may hit 1200°C. Recently, Georgia Tech mechanical engineers studied the kinematics of Chinese restaurant chefs to […]
Once you run out of toilet paper–and you will–make sure you keep the empty rolls so you can try making fantastic molecular models! Physicist and 3D software engineer Ricky Reusser flattened and linked the cardboard tubes into models of buckminsterfullerene and carbon nanotubes! He’s even written a software simulator so you can keep making these […]
Meditation seems simple. Just sit on the floor, clear your mind, and zen out. But have you tried sitting cross-legged on the floor without moving for even 10 minutes? It starts getting mighty uncomfortable after a while. And if you’ve got a few years on you, the knees and thighs are going to be barking […]
