Hyderabad: 14th March 2021 marks Albert Einstein 143rd birthday. Known for his contributions to Theoretical Physics, Albert Einstein became widely known for his mass-energy equivalence formula (E = mc2).
His scientific works
- At the start of his scientific work, Einstein realized the inadequacies of Newtonian mechanics and his special theory of relativity stemmed from an attempt to reconcile the laws of mechanics with the laws of the electromagnetic field.
- He dealt with classical problems of statistical mechanics and problems in which they were merged with quantum theory: this led to an explanation of the Brownian movement of molecules.
- He investigated the thermal properties of light with a low radiation density and his observations laid the foundation of the photon theory of light.
- In his early days in Berlin, Einstein postulated that the correct interpretation of the special theory of relativity must also furnish a theory of gravitation.
- In 1916 he published his paper on the general theory of relativity. During this time he also contributed to the problems of the theory of radiation and statistical mechanics.
- In the 1920s, Einstein embarked on the construction of unified field theories, although he continued to work on the probabilistic interpretation of the quantum theory, and he persevered with this work in America.
- He contributed to statistical mechanics by his development of the quantum theory of a monatomic gas.
- He has also accomplished valuable work in connection with atomic transition probabilities and relativistic cosmology.
- After his retirement he continued to work towards the unification of the basic concepts of physics, taking the opposite approach, geometrisation, to the majority of physicists.
