A new revolutionary laser technology allows bicyclists to carry their own bike lanes with them, with the aid of a new portable device that basically projects the said lane on the street, as the person pedals along idly. The new invention was created specifically with the average bike rider in mind, as the number of r... |

Battles fought in the heights with powerful laser weapons are no longer the product of SF stories, as such a device has recently been tested with success. The Airborne Laser (ABL) was installed on a Boeing 747 airplane and carried aloft, where it fired shortly upon a ground target. Although the laser beam is invisibl... |

All flying vehicles share a common problem – fuel. Their flight duration ability is severely limited by the amount of fuel they can carry, which forces designers to resort to annoying compromises in order to develop craft models with reduced consumption that have enough room for giant fuel reservoirs. But this ... |

An analyst at market research firm iSuppli going by the name of Kevin Keller believes Apple's "Brick" is indeed a laptop in the making. And, while such a radically different production method would boost costs in some areas, overall manufacturing costs would be lower, he claims. So, it's plausible.Yesterday... |

Basically, any liquid column should be able to act as a guide for light, thus behaving similarly to optical fibers. The problem with these liquid fiber optics is that they become unstable after reaching a physical limitation known as the Rayleigh-Plateau instability which states that in free-fall conditions the lengt... |

We often think of lasers as sharp, highly focused beams of light, but the truth is that most of the time lasers have high divergences, spreading light into beams similar to those produced by flashlights. This is especially true for semiconductor lasers, such as those used in building CD-ROM devices and in fiber-optic... |

A one-way mirror is basically just like any other mirror, just that it has the ability of reflecting light on one side while on the other, it is transparent. Typical mirrors achieve a high degree of reflectiveness on one side, leaving the reverse opaque to optical light. This is done by covering the glass layer with ... |

It all started in 1982, when compact discs became commercially available. They were the first optical devices used to store data in a digital format, have typical capacities of up to 700 megabytes, or 80 minutes in audio format, and diameters between 60 to 120 millimeters. In 1997, a new optical storing medium became... |

They don't call them non-le... |
