The Famous Scientists And His contribution For The World

Enrico Fermi

Enrico Fermi was an Italian-American Physicist who created the world’s first nuclear reactor. He is widely known as the “architect of the nuclear age” and the “architect of the atomic bomb.” He won a Nobel Prize in physics for his work on induced radioactivity by neutron bombardment. He also made significant contributions in the field of quantum theory, statistical mechanics and nuclear and particle physics.

Photon, also known as light quantum is a minute energy packet of electromagnetic radiation. This concept originated in Albert Einstein’s explanation of the photoelectric effect, in which he proposed the existence of discrete energy packets during the transmission of light. Albert Einstein was best known for his General and Special theory of relativity and the concept of mass-energy equivalence which is best known from the equation E = mc².

 

 

As discussed before, Rutherford described an atom as consisting of a positive centre mass surrounded by orbiting electrons. Neil Bohr suspected that electrons revolved in quantised orbits. Having suspected this, Bohr worked on Rutherford’s model and proved that it wasn’t possible for electrons to occupy just any energy level.

 

 

Thomas Edison made a lot of inventions and discoveries. Here, we have listed a few noteworthy ones:
• Invented the carbon rheostat
• Discovered incandescent light
• Invented the motion picture camera
• Invented the fluorescent electric lamp
• Discovered Thermionic Emission
Edison has been described as “America’s greatest inventor.” He 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.



Issac Newton’s discoveries created a launch pad for future developments in science. His most noteworthy discoveries were as follows:
• Newton’s three laws of motion set the foundation for modern classical mechanics.
• The discovery of gravitational force gave us the ability to predict the movement of heavenly bodies .
• His discovery of the calculus gave us a potent mathematical tool, aiding the precise analytical treatment of the physical world.
Issac Newton is one of the greatest mathematician and physicist of all time and his inventions and discoveries widened the reaches of human thoughts.
