The title of "Father of Physics" has been earned by 3 great people - Galileo, Isaac Newton, and Albert Einstein. But, according to records available to historians, physics is as old as the Archaic period in Greece (650-480 BC). Whether it was Thales' discovery of water as a fundamental element or Anaximander's proto-evolutionary theory that proposed Apeiron as a primary element, the Greeks contributed a lot to the field of Physics.

However, if asked 'Who is the father of modern physics?' we'd have to visit the early 16th century, the times of Galileo Galilei, to find the answer. Besides Galileo, Isaac Newton and Albert Einstein also contributed massively to physics. Hence, the title of the father of physics in the world goes to three renowned scientists: Galileo Galilei, Isaac Newton, and Albert Einstein.

Who is the Father of Physics? Galileo Galilei (1564 - 1642)

Galileo Galilei, who is Father of Physics, was an Italian mathematician, physicist, and astronomer. He earned the nickname "Father of Physics" because of his pioneering role in finding the motion of bodies and developing the telescope. Incidentally, he confirmed Venus's phases using the telescope and discovered Jupiter's four largest moons.

Learners have been studying his empirical experiments and astronomical discoveries to this day. For example, at 19, Galileo discovered and verified the pendulum's isochronal nature and timed a swinging lamp's oscillations in the Pisa Cathedral.

  • He also invented the concept of 'Hydrostatic Balance' and produced a treatise on solid bodies' centre of gravity.
  • Galileo's experiments on the laws of bodies in motion were subject to intense criticism since they deviated strongly from the Aristotelian physics school's established norms.
  • However, Galileo's theories and concepts formed the basis of the Laws of Motion (Newton) and the Theory of Relativity (Einstein).

Who is the Father of Modern Physics? Isaac Newton (1642 - 1727)

Sir Isaac Newton was associated with Cambridge University as a physicist and mathematician. He was also a fellow Royal Society of England. Newton, the Father of Physics in World, became famous for his three laws of motion which established the connection between motion and objects.

  • He also discovered the Law of Universal Gravitation, which has been instrumental in defining the behaviour of falling bodies, including planets and celestial bodies.
  • Newton also invented calculus in mathematics, which became an integral part of physics shortly after.
  • Newton, who is the first father of physics, published his findings in the Philosophiæ Naturalis Principia Mathematica ('Mathematical Principles of Natural Philosophy), a publication that changed the field of mechanics and astronomy forever.

Who is the Father of Modern Physics? Albert Einstein (1879 - 1955)

Albert Einstein transformed the landscape of physics with his Theory of Relativity and played an instrumental role in designing the theory of Quantum Mechanics.

  • Albert Einstein's mass-energy equivalence formula E = mc2 has etched his name in history books as the greatest physicist of all times.
  • Because of his pioneering role in the field of modern science, and in general and theoretical physics in particular, he was awarded the Nobel Prize in Physics in 1921.
  • He founded the law of the Photoelectric Effect, which played a pivotal role in the formation of the Quantum Theory.
