Michael Faraday (born September 22, 1791, Newington, Surrey, England—died August 25, 1867, Hampton Court, Surrey) was an English physicist and chemist whose many experiments contributed greatly to the understanding of electromagnetism.
Faraday, who became one of the greatest scientists of the 19th century, began his career as a chemist. He wrote a manual of practical chemistry that reveals his mastery of the technical aspects of his art, discovered a number of new organic compounds, among them benzene, and was the first to liquefy a “permanent” gas (i.e., one that was believed to be incapable of liquefaction). His major contribution, however, was in the field of electricity and magnetism. He was the first to produce an electric current from a magnetic field, invented the first electric motor and dynamo, demonstrated the relation between electricity and chemical bonding, discovered the effect of magnetism on light, and discovered and named diamagnetism, the peculiar behaviour of certain substances in strong magnetic fields. He provided the experimental, and a good deal of the theoretical, foundation upon which James Clerk Maxwell erected classical electromagnetic field theory.
Isaac Newton (born December 25, 1642 [January 4, 1643, New Style], Woolsthorpe, Lincolnshire, England—died March 20 [March 31], 1727, London) was an English physicist and mathematician who was the culminating figure of the Scientific Revolution of the 17th century. In optics, his discovery of the composition of white light integrated the phenomena of colours into the science of light and laid the foundation for modern physical optics. In mechanics, his three laws of motion, the basic principles of modern physics, resulted in the formulation of the law of universal gravitation. In mathematics, he was the original discoverer of the infinitesimal calculus. Newton’s Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy, 1687) was one of the most important single works in the history of modern science.
Albert Einstein (14 March 1879 – 18 April 1955) was a German-born theoretical physicist who is best known for developing the theory of relativity. Einstein also made important contributions to quantum mechanics. His mass–energy equivalence formula E = mc2, which arises from special relativity, has been called "the world's most famous equation".He received the 1921 Nobel Prize in Physics for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect.
In 1905, sometimes described as his annus mirabilis (miracle year), he published four groundbreaking papers.In them, he outlined a theory of the photoelectric effect, explained Brownian motion, introduced his special theory of relativity, and demonstrated that if the special theory is correct, mass and energy are equivalent to each other. In 1915, he proposed a general theory of relativity that extended his system of mechanics to incorporate gravitation. A cosmological paper that he published the following year laid out the implications of general relativity for the modeling of the structure and evolution of the universe as a whole.In 1917, Einstein wrote a paper which introduced the concepts of spontaneous emission and stimulated emission, the latter of which is the core mechanism behind the laser and maser, and which contained a trove of information that would be beneficial to developments in physics later on, such as quantum electrodynamics and quantum optics.
Galileo (born February 15, 1564, Pisa [Italy]—died January 8, 1642, Arcetri, near Florence) was an Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion, astronomy, and strength of materials and to the development of the scientific method. His formulation of (circular) inertia, the law of falling bodies, and parabolic trajectories marked the beginning of a fundamental change in the study of motion. His insistence that the book of nature was written in the language of mathematics changed natural philosophy from a verbal, qualitative account to a mathematical one in which experimentation became a recognized method for discovering the facts of nature. Finally, his discoveries with the telescope revolutionized astronomy and paved the way for the acceptance of the Copernican heliocentric system, but his advocacy of that system eventually resulted in an Inquisition process against him.
Niels Bohr (born October 7, 1885, Copenhagen, Denmark—died November 18, 1962, Copenhagen) was a Danish physicist who is generally regarded as one of the foremost physicists of the 20th century. He was the first to apply the quantum concept, which restricts the energy of a system to certain discrete values, to the problem of atomic and molecular structure. For that work he received the Nobel Prize for Physics in 1922. His manifold roles in the origins and development of quantum physics may be his most-important contribution, but through his long career his involvements were substantially broader, both inside and outside the world of physics.
Max Planck (born April 23, 1858, Kiel, Schleswig [Germany]—died October 4, 1947, Göttingen, Germany) was a German theoretical physicist who originated quantum theory, which won him the Nobel Prize for Physics in 1918.
Planck made many contributions to theoretical physics, but his fame rests primarily on his role as originator of the quantum theory. This theory revolutionized our understanding of atomic and subatomic processes, just as Albert Einstein’s theory of relativity revolutionized our understanding of space and time. Together they constitute the fundamental theories of 20th-century physics. Both have forced humankind to revise some of the most-cherished philosophical beliefs, and both have led to industrial and military applications that affect every aspect of modern life.

Field: Physics, Philosophy (Vaisheshika school)
Key Contributions:
Founder of the Vaisheshika School of Indian philosophy, which explained the nature of the universe through atoms (anu) and categories (padartha).
Atomic Theory: Long before modern science, Kanada proposed that:
All matter is composed of indivisible, indestructible particles called anu (atoms).
Atoms combine in various ways to form different types of matter.
These combinations are influenced by forces like motion and time.
Natural Laws: He believed the universe is governed by laws of cause and effect, not divine intervention — a remarkably scientific outlook for his time.
Categories of Reality: Defined six categories (padarthas) that form the structure of the physical world:
Substance (dravya), Quality (guna), Activity (karma), Generality (samanya), Particularity (vishesha), and Inherence (samavaya).
Legacy:
His theories on atoms (over 2,600 years ago) anticipated many ideas later developed in modern atomic physics.
Revered as one of the earliest proponents of materialist and scientific thinking in India.
