N for Nanotechnology

The video is a presentation on nanotechnology. The history of nanotechnology begins in the mid-19th century when the English scientist Michael Faraday first played around with divided metallic particles and showed how properties of metallic systems could change with the reduction of particle size. Then around a century later in 1959 the brilliant Caltech physicist and Nobel Laureate Richard Phillips Feynman predicted the future of technology with his lecture “There is Plenty of Room at the Bottom: An Invitation to Enter a New Field of Physics.” He showed how 24 volumes of the Encyclopaedia Britannica could be printed on the head of a pin. This lecture paved the way for nanotechnology and explorations in the field of quantum mechanics. Nanotechnology sees the future in miniaturization and nano-scale where one meter is equivalent to one billion nanometres. This technology has immense possibilities and uses the bottom-up approach of building from atoms.
