While this is in good humour, I feel it says a lot about the way that science news is sensationalised (continuing the theme). It seems to be a stepwise process, but is one 'step' more to blame than another?

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 !)

Nikola Tesla: A Tribute On His Birthday

Nikola Tesla, Serbian-American inventor and engineer who discovered and patented the rotating magnetic field, the basis of most alternating-current machinery. He also developed the three-phase system of electric power transmission. He emigrated to the United States in 1884 and sold the patent rights to his system of alternating-current dynamos, transformers, and motors to George Westinghouse. In 1891 he invented the Tesla coil, an induction coil widely used in radio technology. Here, we present a short story of his life on his birthday
 
Tesla was born on July 9/10 1856, to a family of Serbian origin. His father was an Orthodox priest; his mother was unschooled but highly intelligent. 

He visualized the principle of the rotating magnetic field and developed plans for an induction motor that would become his first step toward the successful utilization of alternating current.

Tesla soon established his own laboratory, where his inventive mind could be given free rein. He experimented with shadowgraphs similar to those that later were to be used by Wilhelm Röntgen when he discovered X-rays in 1895. Tesla’s countless experiments included work on a carbon button lamp, on the power of electrical resonance, and on various types of lighting.

In 1898 Tesla announced his invention of a teleautomatic boat guided by remote control. When skepticism was voiced, Tesla proved his claims for it before a crowd in Madison Square Garden.

In Colorado Springs, Colorado, where he stayed from May 1899 until early 1900, Tesla made what he regarded as his most important discovery—terrestrial stationary waves. By this discovery he proved that Earth could be used as a conductor and made to resonate at a certain electrical frequency. He also lit 200 lamps without wires from a distance of 25 miles (40 km) and created man-made lightning, producing flashes measuring 135 feet (41 metres). At one time he was certain he had received signals from another planet in his Colorado laboratory, a claim that was met with derision in some scientific journals.

Tesla was the recipient of the Edison Medal in 1917, the highest honour that the American Institute of Electrical Engineers could bestow.

Tesla allowed himself only a few close friends. Among them were the writers Robert Underwood Johnson, Mark Twain, and Francis Marion Crawford. He was quite impractical in financial matters and an eccentric, driven by compulsions and a progressive germ phobia. But he had a way of intuitively sensing hidden scientific secrets and employing his inventive talent to prove his hypotheses. Caustic criticism greeted his speculations concerning communication with other planets, his assertions that he could split the Earth like an apple, and his claim of having invented a death ray capable of destroying 10,000 airplanes at a distance of 250 miles (400 km).

He died on January 7, 1943 in New York.
