Factors responsible for progress of Physics

  • Quantitative analysis along with qualitative analysis.
  • Application of universal laws in different contexts.
  • Approximation approach (complex phenomena broken down into collection of basic laws).
  • Extracting and focusing on essential features of a phenomenon.

Hypothesis, Axiom and Models

Hypothesis is a supposition without assuming that it is true. It may not be proved but can be verified through a series of experiments.

Axiom is a self-evident truth that it is accepted without controversy or question.

Model is a theory proposed to explain observed phenomena.

Assumption is the basis of physics, where a number of phenomena can be explained. These assumptions are made from experiments, observation and a lot of statistical data.

Technological applications of Physics

Several examples where Physics and its concepts have led to discoveries/inventions are listed below.

  • Steam engine was developed from the industrial revolution in eighteenth century.
  • Wireless communication was developed after discovery of laws of electricity and magnetism.
  • Neuron-induced fission of uranium, done by Hahn and Meitner in 1938, led to the formation of nuclear power reactors and nuclear weapons.
  • Conversion of solar, wind, geothermal into electricity.
