Motorola Mobility‚ the ailing cellphone maker that Google bought in May‚ told employees Sunday that it would lay off 20 percent of its work force and close a third of its 94 offices worldwide. The cuts are the first step in Google’s plan to reinvent Motorola‚ which has fallen far behind its biggest competitors‚ Apple and Samsung‚ and to shore up its Android mobile business and expand beyond search and software into the manufacture of hardware. The turnaround effort will also be a referendum on

half human‚ half machine‚ are possible in the next decade. Aside from the philosophical and moral issues that are brought up‚ and a slight tangent‚ I just want to know if it is possible based on Moore ’s law to have living cyborgs exist with silicon chip circuitry running in their brain giving them a large advantage in memory and computing power over average humans. This was inspired by my younger self dreaming about having super memory or imagining if a teacher could insert a USB into my head and I could

Super Regions of the Philippines The "super" regions of the Philippines are an informal grouping of parts of regions and provinces of the Philippines based on their economic strengths. The creation of "super" regions was first proposed by the President Gloria Macapagal-Arroyo in her sixth State of the Nation Address to group the selected regions/provinces by their economic strengths.

are microchips made? By definition the integrated circuit aka microchip is a set of interconnected electronic components such as transistors and resistors‚ that are etched or imprinted on a onto a tiny chip of a semiconducting material‚ such as silicon or germanium. The History of the Integrated Circuit Jack Kilby and Robert Noyce It seems that the integrated circuit was destined to be invented. Two separate inventors‚ unaware of each other’s activities‚ invented almost identical integrated

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power. It is composed of semiconductor material with at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be higher than the controlling (input) power‚ a transistor can amplify a signal. Today‚ some transistors are

important of these elements are silicon and germanium. Semiconductor materials are useful because their behaviour can be manipulated by the addition of impurities‚ known as doping .Doping a semiconductor with a small amount of impurity atoms greatly increases the number of charge carriers within it. When a doped semiconductor contains excess holes it is called "p-type"‚ and when it contains excess free electrons it is known as "n-type". Germanium‚ gallium arsenide‚ and silicon carbide are common dopants
