Nanotechnology

Nanotechnology is the science and engineering of microscopic things to be used for other sciences.

How It Started

The concept of nanotechnology started with an article called “There’s Plenty of Room at the Bottom” by  Richard Feynman long before the word nanotechnology was used. In his article, Feynman described a process were scientists would be able to control individual atoms and molecules. Years later, while working with ultra-precision machining, Professor Norio Taniguchi used the term nanotechnology. This wasn't until 1981, with the development of the microscope that could "see" individual atoms.

Measurements

They use different measurements for reference. On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth. There are 25,400,000 nanometers in an inch. The microscopes needed to see things at the nanoscale were invented about 30 years ago. Although nanotechnology is quite new, nanoscale things were used for centuries. Gold and silver particles created colors in the stained glass windows of medieval churches a good 800 years ago. The artists back then just didn’t know that the process they used to create these works of art led to changes in the materials they were working with.

Pros

  1. It's possible nanotechnology can eliminate recycle extra trashes, stop different diseases, and lead to important break through, they eliminate the needs for landfills, and even remove different air toxins.
  2. This technology will allow humans to create anything lighter, stronger, better, and cheaper.
  3. Nanotechnology can stop diseases internally.
  4. Nanotechnology will make more jobs due to the fact there will be a great demand for highly skilled workers, researchers, and more teachers. This will boost the economy greatly.

Cons

  1. The nanobots can also be used weapons by terrorist groups like the Taliban and ISIS, as these robots are almost undetectable.
  2. There are also severe health problems if nanobots accidently land in the human body. There have been reports and cases of workers at paint factories suffering from lung diseases due to the inhaled nanoparticles.
  3. With nanotechnology, there is the possibility of developing self replicating weapons
  4. Strong sets of new ethical standards are needed in order for this new technology to be properly governed. Some people believe that people do not have capability of watching over this new technology, which can lead to issues and problems that can affect the people and the rest of the world.

Conclusion

Today's scientists and engineers are finding new ways to purposely make materials at the nanoscale to take advantage of their properties such as more strength, lighter, and greater chemical reactivity than their larger-scale relatives.
