Who propounded the famous equation $$E = mc^2$$​ in 1905?

Correct option is C

The correct answer is (c) Albert Einstein

Explanation:

• The famous equation E = mc² was propounded by Albert Einstein in 1905 as part of his special theory of relativity.
• The equation represents the equivalence of energy (E) and mass (m), with c being the speed of light in a vacuum ($$3 \times 10^8 \, m/s$$​).

Theory of Relativity:

• The equation E = mc² suggests that a small amount of mass can be converted into a large amount of energy, which is the principle behind the functioning of nuclear reactors and atomic bombs.
• This equation demonstrates that mass can be converted into energy and vice versa, showing the profound relationship between matter and energy.
• Einstein's theory also introduced the concept that the laws of physics are the same for all observers in uniform motion relative to one another, and that the speed of light is constant in all inertial frames of reference.

Additional Knowledge:

Werner Heisenberg

• Discovery: Heisenberg is best known for his Uncertainty Principle, formulated in 1927.
• Uncertainty Principle: States that it is impossible to simultaneously measure both the position and momentum of a particle with absolute precision.
• Other Contributions: Heisenberg contributed to the development of quantum mechanics, particularly through the creation of matrix mechanics.

2. Isaac Newton

• Discovery: Newton is famous for his Laws of Motion and Universal Law of Gravitation.
• Laws of Motion: Three fundamental principles that describe the relationship between the motion of an object and the forces acting on it.
• Universal Law of Gravitation: States that every particle of matter in the universe attracts every other particle with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.

3. Ernest Rutherford

• Discovery: Rutherford is known for his Gold Foil Experiment (1909), which led to the discovery of the nucleus.
• Gold Foil Experiment: Discovered that atoms have a dense, positively charged nucleus at their center, with electrons orbiting outside, disproving the earlier plum pudding model of the atom.
• Other Contributions: Rutherford's work also led to the identification of radioactive decay and the discovery of alpha and beta radiation.
