The smooth motion of rotating circles can be used to build up any repeating curve even one as angular as a digital square wave. Each circle spins at a multiple of a fundamental frequency, and a method called Fourier analysis shows how to pick the radiuses of the circles to make the picture work. Decomposing signals like this lies at the heart of a lot of signal processing .

Nano-Cone Textures Generate Extremely "Robust" Water-Repellent Surfaces

❂ A team of scientists at the U.S. Department of Energy's Brookhaven National Laboratory found out that the cone shaped nanostructures achieved significant robust water repellency compared to the silicon surface textured with cylindrical pillar.

❂ The incredible droplets shown in this gif was captured at 30,000 frames per second—bounce along the superhydrophobic surface. Can move forward this technology for vehicle windshield to improve visibility (especially when it is raining cats and dogs !)
