from the play Rossum Universal Robots, showing three robots) Many striking innovations and discoveries originate from scientific fictions. Robots are also no exception to this. Te word robotics was derived from the word robot. It was introduced in the play ‘Rossum Universal Robots’ by the Zech writer Karel Capek in .
Te word robot comes from the Slavic word rabota, which means labour or work. Te play begins in a factory that makes artificial people called robots. Tey looked like creatures that can be mistaken for humans (picture shown). Tese characters were very similar to the modern ideas of androids.
Quantum information theory (Not for examination) It is another fast developing research area which deals with improving the information storage using quantum computers. Te present computers store information in the form of ‘bits’ but quantum computers store information in the form of ‘qubits’. ‘qubit’ refers to quantum bit and it is the basic unit of quantum information. Classical bit implies either or .
But qubit not only includes or and also linear superposition of and . Tis technology reduces the calculating time exponentially. Tis research field has very promising application in future. Qubit Information is physical Nature is quantum Quantum information processing Head (' ') Tail (' ') or α β - - - - Unit Recent developments in physics Salient physics principles (covered in the higher secondary physics) are the foundation for technology break through.
Physics is the basic building block for Science, Engineering, Technology and Medicine. Nano science is the science of objects with typical sizes of – nm. Nano means one-billionth of a metre that is – m. Nanotechnology is a technology involving the design, production, characterization, and applications of nano structural materials.
If the particle of a solid is of size less than nm, it is said to be a ‘nano solid’. When the particle size exceeds nm, it forms a ‘bulk solid’. Nano form of the material shows strikingly different properties when compared to its bulk counterpart. Quantum confinement effects and surface effects are
