Introduction to Physics, Technology and Society

Technology has been reshaping itself from time and time. The functioning of the world is entirely different from the way it used to be. Advancements in science have played a great role in inventions of new technologies. For Example: Mobiles; they revolutionized from the keypad to touch screens with the help of new chipsets and networking technologies. Developers and scientists are now looking forward to turn smartphones into flexible and foldable. This is how technologies grow from one form to another to make human life more comfortable and economical.

Introduction to Physics, Technology and Society

To improve technology we understand the needs of society and figure out how principles of physics can help us in achieving our objectives.

Example: Earlier people thought that energy can’t be obtained by atoms. But ironically we do produce nuclear energy from atoms to meet the energy-related needs of the society.

All inventions from the iron pin to gigantic space ships, everything is the product of physics concept and critical thinking. This makes understanding of physics more compulsory for the development of the society.

How Physics, Technology, and Society are related?

Physics, Technology, and Society are relatedThe term physics, technology, and science are interrelated terms. The connection between science, technology, and science can be understood through following examples:

  • Thermodynamics- branch of science which deals with energy and matter, came into existence when people felt the need to understand and improve the efficiency of engines. Study of thermodynamics helped in inventions like vehicles, new engines, refrigerators, blowers etc.
  • The invention of steam engine is responsible for the Industrial Revolution in England and had affected human civilizations
  • Existing physics help in framing new technology and sometimes discover new physics concepts. For example, the wireless technology is framed through concepts of current, electricity and magnetism given in the 18th century
  • The silicon chip is credit worthy for computer revolution for the last three decades. This was possible with the advancement of semiconductors and basic electronics, which are sub-branches of Physics

The applications of physics in real life become tough when certain experimental conditions are not maintained during the experiment. Earlier great physicist Ernest Rutherford failed to extract energy from atoms, but later on, in the year 1938, two physicists Hahn and Meitner attained a process through which neutron of Uranium atom can be induced with its fission. This induced-neutron phenomenon is used in nuclear plants to produce nuclear energy and supply nuclear weapons.

Physics and Energy Resources

Physics and Energy Resources

Alternate energy resource saving is the area where physics contributes the most. Alternate energy resource saving involves proper utilization of resources. Proper utilization of resources is done through several agendas and programs like Sustainable Development, Recycling etc.

Example: Fossil fuels are tapering off and there is an urgent need to find efficient and affordable sources of energy. Much of the problem is solved with energy conversion forms devised from physics laws, as now we know how to convert geothermal or solar energy to electricity.
