Good news for all those who were thinking of getting a tattoo but were too afraid of having to explain to their future children what's with the flaming skull on their arm: the first permanent, removable tattoo was developed by a team of scientists. Most tattoos are made in times when teens or adults want to pro... |

A new discovery in the field of nanotechnology could produce the smallest machines in history. The best part is that scientists will be able to remotely control them using rays of UV light, due to their shapeshifting properties.Physicists at the University of California at Berkeley presented the latest discovery in... |

Lenses are used to converge or diverge light in various optical and electronic devices and the first written records of the use of a lens date to Ancient Greece, in 424 BC. The optical zoom lenses in professional television cameras can have a magnification ratio as high as 100x.There are some things that a single mi... |

You were young (and foolish) and you wanted a tattoo to prove your independence or to make a statement. Now you're older (hopefully wiser too) and think about removing them, so you won't have to explain to your children what's with the naked lady on your arm.Many people decide to have a tattoo as a sy... |

It is widely believed that if large-scale quantum computers can be built, they will be able to solve certain problems exponentially faster than any classical computer. Finding a way to build such a computer that works more efficiently than a classical computer has been the holy grail of quantum information processin... |

The free electron laser has almost the same properties as the optical type, meaning the coherent beam of electron radiation, but uses different operating principles to create the beam. Unlike gas, liquid, or solid-state laser applications, such as diode lasers, which rely on bound atomic or molecular states, Free el... |

No telescope can form a perfect image. Even if a reflecting telescope could have a perfect mirror, or a refracting telescope could have a perfect lens, the effects of aperture diffraction could still not be escaped.The blurring effect from the atmosphere is among the most important distortions that affect telescopes... |

The word hologram comes from Greek, with holos meaning whole and graphe meaning writing. A hologram is an advanced form of photography that allows an image to be recorded in three dimensions, in fact a recording of an interference pattern made by the interaction of two beams of light.A company in Dresden, Germany, ca... |

What is electromagnetically induced transparency? It's a coherent optical nonlinearity which renders a medium transparent over a narrow spectral range within an absorption line. Extreme dispersion is also created within this transparency "window" which leads to "slow light."Now, a team of scientists, made up of... |

What happens when you throw a golf ball at a locomotive speeding toward you? The ball will bounce off it and come flying back at you with tremendous energy, just before you get run over. This is what scientists are trying to study with a new generation of x-ray lasers.Scientists developed a new method of producing i... |

Harvesting solar energy is a clever way to make use of a clean and renewable fuel. You don't need to dig the ground for it, there are no pipes and powerplants, and best of all, it's ecological. Unfortunately, existent solar cells are not too efficient and can't convert more than 10 percent of the sola... |

A new experiment performed in the US has proved that a Bose-Einstein condensate can exist in polaritons, a cooled system of particles. This is not the first time scientists claim to have the proof of its existence, but in similar previous applications many suspected that the coherence was in fact the effect of the l... |

Starting with the first half of the 20th century it has been apparent that the Universe is made up of more than just the things we can see. It is now widely accepted that a large fraction of the Universe consists of "dark matter" in the form of a new type of fundamental particle. In astrophysics and cosmology, dark ... |

The word Laser is an acronym for "light amplification by stimulated emission of radiation". Lasers are possible because of the way light interacts with electrons. Electrons exist at specific energy levels or states characteristic of that particular atom or molecule. The energy levels can be imagined as rings or orbi... |

LASER - Light Amplification by Stimulated Emission of Radiation. It's a combined quantum-mechanical and thermodynamical process, a light source with various properties that emits light in a narrow and well-defined beam and with a well-defined wavelength (or color).There are some constraints, however, regarding ... |

Every material exposed to high-intensity light will degrade over time. White paper turns yellow, dyes bleach and fade, and molecules that fluoresce when struck by a laser - as the chemical in the present study does - stop fluorescing. Until recently, that degradation in response was thought to be irreversible.Physici... |

Electrons have a negative charge and are glued into atoms by the attractive force of its positively charged nucleus. In classical physics, an electron could not escape from an atom unless it received enough energy to overcome this force by ascending the nucleus' "potential barrier".But quantum mechanics allows ... |
