Tablet PC

A tablet PC is a notebook or slate-shaped mobile computer, first introduced by Pen computing in the early 90s with their PenGo Tablet Computer and popularized by Microsoft. Its touchscreen or graphics tablet/screen hybrid technology allows the user to operate the computer with a stylus or digital pen, or a fingertip, instead of a keyboard or mouse. The form factor offers a more mobile way to interact with a computer. Tablet PCs are often used where normal notebooks are impractical or unwieldy, or do not provide the needed functionality.

Rocket

rocket or rocket vehicle is a missile, spacecraft, aircraft or other vehicle which obtains thrust by the reaction of the rocket to the ejection of fast moving fluid exhaust from a rocket engine. Chemical rockets create their exhaust by the combustion of rocket propellant. The action of the exhaust against the inside of combustion chambers and expansion nozzles is able to accelerate the gas to hypersonic speed, and this exerts a large reactive thrust on the rocket (an equal and opposite reaction in accordance with Newton's third law).
Rockets, in the form of military and recreational uses, date back to at least the 13th century.[1] Widespread military, scientific, and industrial use did not occur until the 20th century, when rocketry was the enabling technology of the Space Age, including setting foot on the moon.

General intelligence

Main articles: Strong AI and AI-complete
Most researchers hope that their work will eventually be incorporated into a machine with general intelligence (known as strong AI), combining all the skills above and exceeding human abilities at most or all of them.[12] A few believe that anthropomorphic features like artificial consciousness or an artificial brain may be required for such a project.[72]
Many of the problems above are considered AI-complete: to solve one problem, you must solve them all. For example, even a straightforward, specific task like machine translation requires that the machine follow the author's argument (reason), know what is being talked about (knowledge), and faithfully reproduce the author's intention (social intelligence). Machine translation, therefore, is believed to be AI-complete: it may require strong AI to be done as well as humans can do it.[73]

Silicon Valley

Silicon Valley is the southern part of the San Francisco Bay Area in Northern California, United States. The term originally referred to the region's large number of silicon chip innovators and manufacturers, but eventually came to refer to all the high-tech businesses in the area; it is now generally used as a metonym for the high-tech sector. Despite the development of other high-tech economic centers throughout the United States, Silicon Valley continues to be the leading high-tech hub because of its large number of engineers and venture capitalists. Geographically, Silicon Valley encompasses the northern part of the Santa Clara Valley and adjacent communities.

Laser

A laser is a device that emits light (electromagnetic radiation) through a process called stimulated emission. The term laser is an acronym for light amplification by stimulated emission of radiation.[1][2] Laser light is usually spatially coherent, which means that the light either is emitted in a narrow, low-divergence beam, or can be converted into one with the help of optical components such as lenses. Typically, lasers are thought of as emitting light with a narrow wavelength spectrum ("monochromatic" light). This is not true of all lasers, however: some emit light with a broad spectrum, while others emit light at multiple distinct wavelengths simultaneously. The coherence of typical laser emission is distinctive. Most other light sources emit incoherent light, which has a phase that varies randomly with time and position.

Spy Satellites

The recent much publicized shooting down of a US Spy Satellite, out of control (or so they say) and plummeting towards Earth has raised the level of interest in what is up in Space, looking down on us, watching our every movement, and listening to our every electronic transmission.
Any one can look up civilian satellite images thanks to Google, and other image providers. The resolution of these free images from space are better than the Top Secret satellite images of only a few years ago. Today you can begin your Spy Games on your browser, at home.

Cloning

This case was written for a high school introductory biology class. The purpose of the case is to provide students with an opportunity to discuss animal cloning and its moral implications. It was designed to be given to students at the conclusion of a unit on genetics in which cloning has been thoroughly discussed. The case makes use of a debate format. Students read the case, in which a family pet has died, and assume the roles of the family members who must distinguish between conflicting opinions as to whether or not the animal should be cloned. In order to minimize disruption to other classrooms and teachers, the author recommends that the case be conducted in the school auditorium. As developed, the case requires two 40-minute class periods, ideally run back to back. In preparation for the case, students will need detailed prior knowledge regarding the topic of cloning, including what genetic cloning is and what it involves.
