Sommario/riassunto |
|
Superconductivity is a quantum phenomenon that manifests itself in materials showing zero electrical resistance below a characteristic temperature resulting in the potential for an electric current to run continually through such a material without the need for a power source. Such materials are used extensively in medical and power applications, e.g. MRI and NMR machines. Discovering Superconductivity uses a series of practical and investigative activities, which can be used as tutor demonst |

As author of the hugely influential The Economic History of India 1857-1947, Tirthankar Roy has established himself as the leading contemporary economic historian of India. Here, Roy turns his attention to labour and livelihood and the nature of economic change in the Subcontinent. This book covers:economic history of modern India rural labour labour-intensive industrialization women and industrialization.Challenging the prevailing wisdom on Indian economic growth - that it is bound up with Marxian, postcolo |
