Everyone has seen how the car windscreen wipers sweep the water away quickly But did you ever think about how they work? There is only one fixed point, it is attached to the long arm of a lever with a brush that adheres to the glass. If there is an engine that can operate this mechanism, it must turn in one direction, then stop suddenly and turn in the opposite direction. But how it is actually built on the wiper mechanism? If you open the hood you can see that the wiper motor always rotates in the same way, all the time when it is activated. But it is a planar hinge mechanism, called windscreen trapezoid, that rotates now in one direction, now in the opposite one. What is a planar hinges mechanism? In short, it is made of bars of different lengths arranged on a plane and connected at their ends by nails. In practice we encounter them everywhere. The research on hinges mechanism in mathematics began at the time of the invention of the steam engine by James Watt and continue in our time. Mathematicians of the twenty-first century proved the “signature theorem”: there is a planar hinges mechanism that forges your signature with any precision.  http://en.wikipedia.org/wiki/Watt_steam_engine

Pff, I could draw shapes like that in logo when I was 8. (granted it wasn't animated, and didn't have 32-bit antialiased text flowing around it in real time, and wasn't in a web browser, but I judge all of that to be trivial details).

Blurb: This is not a scene from a sci-fi special effects movie. The green beam of light and red lunar disk are real enough, captured in the early morning hours of April 15. Of course, the reddened lunar disk is easy to explain as the image was taken during this week's total lunar eclipse. Immersed in shadow, the eclipsed Moon reflects the dimmed reddened light of all the sunsets and sunrises filtering around the edges of planet Earth, seen in silhouette from a lunar perspective. But the green beam of light really is a laser. Shot from the 3.5-meter telescope at Apache Point Observatory in southern New Mexico, the beam's path is revealed as Earth's atmosphere scatters some of the intense laser light. The laser's target is the Apollo 15 retroreflector, left on the Moon by the astronauts in 1971. By determining the light travel time delay of the returning laser pulse, the experimental team from UC San Diego is able to measure the Earth-Moon distance to millimeter precision and provide a test of General Relativity, Einstein's theory of gravity. Conducting the lunar laser ranging experiment during a total eclipse uses the Earth like a cosmic light switch. With direct sunlight blocked, the reflector's performance is improved over performance when illuminated by sunlight during a normal Full Moon, an effect fondly known as The Full Moon Curse.

Introduction

These are the things that I post about or share, and these are the types of circles you should add me to:
  • Science, especially astronomy, biology, evolution
  • Linux/Ubuntu, Android, open source
  • Science Fiction like Doctor Who, Battlestar Galactica.  I really like space operas à la Alastair Reynolds.
  • Atheism, Anti-theism, and skepticism
  • LGBT
  • Cats (duh)
