How sometimes technology gives rise to …

Ans. The connection between physics, technology and society can be seen in many examples. The discipline of thermodynamics arose from the need to understand and improve the working of heat engines. The steam engine is inseparable from the Industrial Revolution in England in the eighteenth century, which had great impact on the course of human civilisation. Sometimes technology gives rise to new physics; at other times physics generates new technology

We can understand this by some examples :

• The wireless communication technology that followed the discovery of the basic laws of electricity and magnetism in the nineteenth century.
   
• Development of Alternative Energy Resources : A most significant area to which physics has and will contribute is the development of alternative energy resources. The fossil fuels of the earth are ending fast and there is an urgent need to discover new and affordable sources of energy. Considerable progress has already been made in this direction. For example : Conversion of solar energy, geothermal energy into electricity.
   
• Silicon Chip Technology : Yet another important example of physics giving rise to technology is the silicon chip, that triggered the computer revolution in the last three decades of the twentieth century.
