Nano technology referred to the particular technological goal of precisely manipulating atoms and molecules for fabrication of macro scale products, also now referred to as molecular nanotechnology which defines nanotechnology as the manipulation of matter with at least one dimension sized from 1 to 100 nano meters.

10 Best Hackers The World Has Ever Known
1.
Gary McKinnon
Gary McKinnon
must’ve been a curious, restless child, for to gain information on UFOs, he
thought it better to get a direct access into the channels of NASA. He
infiltrated 97 US military and NASA computers, by installing virus and deleting
a few files. All the efforts to satisfy his curiosity, but, alas, curiosity
killed the cat. It was soon found that McKinnon was guilty of having hacked the
military and NASA websites from his girlfriend’s aunt’s house in London. While
entering and deleting the files from these websites wasn’t enough, McKinnon
thought of shaming the security forces by putting out a notice on the website
that said, “Your security is crap.” Well, looks like McKinnon was something, if
he could shut down the US Military’s Washington Network of about 2000 computers
for 24 hours, making the hack, the biggest military computer hack of all time!

BIO TECHNOLOGY
BIO TECHNOLOGY = At its simplest, biotechnology is technology based on biology - biotechnology harnesses cellular and biomolecular processes to develop technologies and products that help improve our lives and the health of our planet.Currently, there are more than 250 biotechnology health care products and vaccines available to patients, many for previously untreatable diseases. More than 13.3 million farmers around the world use agricultural biotechnology to increase yield.
WHAT IS BIO GASS =
Bio gas typically refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Bio gas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste
HOW TO MANUFACTURING BIO GASS=
Regardless of your design, avoid using biogas or any other fuel to heat your digester. Make sure energy you use is excess energy on its way to being wasted. Step 4. Neutral pH is an important parameter in anaerobic digestion, just as it is for aerobic composting
GENRAL USED BIO TECHNOLOGY =
- Generation of electricity and heat (CHP)
- Feeding biogas into the natural gas grid
- Use in the mobility sector

HOLOGRAM TECHNOLOGY
Holography is the science and practice of making holograms. Typically, a hologram is a photographic recording of a light filed, rather than of an image formed by a lens, and it is used to display a fully 3-D image of the holography subject, which is seen without the aid of special glass or other intermediate optics.
The hologram itself is not an image and it is usually unintelligible when viewed under diffuse reflection light. It is an encoding of the light field as an interface pattern of seemingly random variations in the opacity, density, or surface profile of the photographic medium. When suitably lit, the interference pattern diffraction the light into a reproduction of the original light field and the objects that were in it appear to still be there, exhibiting visual depth cues such as parallax and virtual that change realistically with any change in the relative position of the observer.
In its pure form, holography requires the use of laser light for illuminating the subject and for viewing the finished hologram. In a side-by-side comparison under optimal conditions, a holographic image is visually indistinguishable from the actual subject, if the hologram and the subject are lit just as they were at the time of recording. A microscopic level of detail throughout the recorded volume of space can be reproduced. In common practices, however, major image quality compromises are made to eliminate the need for laser illumination when viewing the hologram, and sometimes, to the extent possible, also when making it.
LASER : In laser holography, the hologram is recorded using a source of laser light, which is very pure in its color and orderly in its composition.
PHYSICS OF HOLOGRAPHY : For a better understanding of the process, it is necessary to understand optics and diffraction. Interference occurs when one or more wave front are superimposed. Diffraction occurs whenever a wave front encounters an object. The process of producing a holographic reconstruction is explained below purely in terms of interference and diffraction.
HOW IT WORK :Holography is a technique that enables a light field, which is generally the product of a light source scattered off objects, to be recorded and later reconstructed when the original light field is no longer present, due to the absence of the original objects. Holography can be thought of as somewhat similar to sound recording, whereby a sound field created by vibrating matter like musical instruments is encoded in such a way that it can be reproduced later, without the presence of the original

WHAT IS NANO TECHNOLOGY ?
Nanotechnology is science, engineering, and technology conducted at the nano scale, which is about 1 to 100 nano meters.
One nano meter is a billionth of a meter, or 10-9 of a meter. Here are a few illustrative examples:
- There are 25,400,000 nano meters in an inch
- A sheet of newspaper is about 100,000 nano meters thick
