About Technology

The world is shrinking into a global village as the horizon of technology expand.It is a hybrid field of applied science and technology. Nanotechnology focuses on manipulating atoms individually and placing them in a pattern to produce a desired structure. It is diverse field that has various branches colloidal science, applied physics, material science, supramolecular chemistry, device physics and even electrical and mechanical engineering. Nanotechnology uses two main approaches, known as to-up and bottom-down approaches.

In the "top-down" approach, the nano-objects are assembled from larger molecular objects without atomic-level control. In the "bottom-up" approach, materials and devices are built from molecular components which constructs chemically by the principles of molecular recognition. Instances of nanotechnology in recent use are the production of polymers based on molecular structure, and the design of computer chip layouts based on surface science. When the nanotechnology is implemented in image analysis software, some computers are able to study a consumer’s body language and, with exact programming can precisely understand a person's position, impatience and diverse facial expressions like frowning, smiling or scowling.

Human skin has the ability of broadcasting the electric signals which can be used as a method of transmission, researchers have already been able to develop computers that are designed with nano sensors that have the strange ability to 'see' and 'hear' the people using them in reality. Nanotechnology would facilitate manufacturing of new generation of computer components with massive storage capacity. In the field of computer science, there is something called as Moore's Law which states that, in layman's terms, the processing abilities of the basic computer chip have been increasing exponentially to a greater heights every eighteen months since their inception.

The evolution of the computers clearly shows us that mechanical computing tradition was not completely abandoned. In 1990, University of Minnesota engineers fabricated an entire family of micromechanical digital logic devices, including electrostatically-actuated linear sliding micron mechanical logic elements limited to a one-dimensional track, suitable for low speed radiation-hard digital works in an environment hostile to the electronic devices to operate. Perhaps the best-characterized mechanical nanocomputer is Drexler's rod logic design which is though not yet built. In this model, one sliding rod with a knob interconnects at first a second knobbed sliding rod at right angles. Based upon the location of the first rod, the second may be able to move, or unable to move. This straightforward blocking contact serves as the basis for logical operations.

There has been a lot of research work going on this for the betterment of the mankind. In a press meet to Journal of Applied Sciences Hewlett-Packard said that their scientists have invented an alternative to eventually replace the transistors in computers. This was demonstrated by their Quantum Science Research group. They have invented a "crossbar latch," which supplies the signal restoration and inversion necessary for general computing without the need for transistors.

Quantum physics has shown that immortality has now become a reality. Every one of us, need to take a come across this bigger picture and make a decision how we feel about it, and where we fit in.
