Nanotics is a technology of separating a material into molecules of the smallest unit and assembling it to create a new substance. In 1959, Richard Feynman, who was an American theoretical physicist, discovered nanotechnology and declared it to the world. In a lecture held by the American Physical Society at the California Institute of Technology, he claimed that removing elements from atoms would create emtpy spaces, stating that information from around the world could be stored in a small device and build up a countless universe in that void. Then in 1987, Eric Drexler, a nanotechnology researcher and engineer, spoke directly about his field of nanotechnology and the future of it. He also alluded to his thoughts that any substance could be created through a combination of any molecule of matter using molecular assemblers.
Nowadays, nanotechnology is developing at a fast rate, now setting a goal of using nanotechnology in a moral and legitimate way. Although it hasn't fully developed yet to apply in most fields, nanotechnology is expected to open up the Fourth Industrial Revolution in the not faraway future.
