Scientists make Ball Lightning in the lab for the first time |

Lightning ball
If you have ever seen a mysterious ball of lightning chasing a cow or flying through your window during a thunderstorm, take comfort from the fact that you have witnessed a very rare phenomenon. Indeed, ball lightning -- a slow-moving ball of light that is occasionally seen at ground level during storms -- has puzzled scientists for centuries. Now, however, researchers in Israel have built a system that can create lightning balls in the lab. The work may not only help us to understand ball lightning but could even lead to practical applications that make use of these artificial balls (Phys. Rev. Lett. 96 045002). |

Slick as a stick of butter this is.
GPS Visualizer is a free on-line utility that creates maps and profiles from GPS data (tracks and waypoints), street addresses, or simple coordinates. Use it to see where you've been, plan where you're going, or visualize geographic data (business locations, events, customers, real estate, etc.). |

Winfoil model aircraft designer |
|
|
Winfoil is a an aeronautical computer aided design tool for designing, analysing and modifying model aircraft. It also provides the ability to print the design (wing ribs, fuselage sides, wing and tail plans) to any Windows supported printer and export design components to DXF files for import into other CAD programs such as AutoCAD. It is typically used for Radio Control Gliders, Powered Aircraft (Scale,Sport and Pylon). |

The Mathematical Magic of the Fibonacci Numbers |
|
|
This page looks at some patterns in the Fibonacci numbers themselves, from the digits in the numbers to their factors and multiples and which are prime numbers. There is an unexpected pattern in the initial digits too. We also relate Fibonacci numbers to Pascal's triangle via the original rabbit problem that Fibonacci used to introduce the series we now call by his name. |
