Question

2) Mention any one favourite physicist and his/her contribution to physics.
​

Answer 1

Answer:

Albert Einstein

Explanation:

Albert Einstein

Three great theories define our physical knowledge of the universe: relativity, quantum mechanics and gravitation. The first is the handiwork of German-born Albert Einstein (1879-1955), who remains the physicist with the greatest reputation for originality of thought. His work showed that space and time are not immutable but are fluid and malleable. Einstein, who took US citizenship in 1940, also provided the world with its most famous equation, E=mc2, which demonstrates the equivalence of mass and energy. His name has become synonymous with the idea of genius and he died a celebrity. He was awarded the 1921 Nobel prize for physics.

Answer 2

Isaac Newton was a physicist and mathematician who developed the principles of modern physics including the law of motions.

Thomas Alva Edison was one of the most famous and prolific inventors of all time and he exerted a tremendous influence on modern life, contributing so many inventions in physics.

   

Explanation:

Isaac Newton:

• Co-inventor of calculus, a major contributor to the science of optics and a gifted mathematician, Isaac Newton.

• Issac Newton outlined the laws of mechanics that now underpin vast swaths of classical physics which includes the law of motion and is credited as one of the greatest minds of the 17th-century.

• Most important of all, Newton outlined the principle of gravity, which explained how the planets revolve around the sun.  

Thomas Alva Edison:

• Thomas Edison made a lot of key inventions and discoveries.

Here, we have listed a few important ones.

• Invented the carbon rheostat
• Discovered incandescent light
• Invented the motion picture camera
• Invented the fluorescent electric lamp
• Discovered thermionic emission

Thomas Edison has been represented as "America's greatest inventor."

• Edison developed many devices in fields like mass communication and electric power generation.

• He was one of the pioneers in applying the principles of organized science and teamwork to the process of invention, working with many researchers and employees.
