  1. When Albert Einstein formulated his theory of general relativity (GR) he turned his attention to the problem of Mercury's orbit and found that his theory added a correction, which could account for the discrepancy.
  2. By the early 20th century, Einstein developed a theory of relativity that correctly predicted the action of forces on objects with increasing momenta near the speed of light, and also provided insight into the forces produced by gravitation and inertia.
  3. :247 He was also critical of Einstein's theory of relativity, saying:
  4. Since then, and so far, general relativity has been acknowledged as the theory that best explains gravity.
  5. Einstein tried and failed at this endeavor, but currently the most popular approach to answering this question is string theory.
  6. Albert Einstein extended the principle of inertia further when he explained that reference frames subject to constant acceleration, such as those free-falling toward a gravitating object, were physically equivalent to inertial reference frames.
  7. Tesla claimed to have developed his own physical principle regarding matter and energy that he started working on in 1892, and in 1937, at age 81, claimed in a letter to have completed a "dynamic theory of gravity" that "[would] put an end to idle speculations and false conceptions, as that of curved space."
  8. With the development of quantum field theory and general relativity, it was realized that force is a redundant concept arising from conservation of momentum (4-momentum in relativity and momentum of virtual particles in quantum electrodynamics).
  9. This was the first time that Newton's Theory of Gravity had been shown to be less correct than an alternative.
  10. A. Michelson, elementary charge calculator Robert A. Millikan, discoverer of the Compton Effect Arthur H. Compton, the creator of the first nuclear reactor Enrico Fermi, "the father of the hydrogen bomb" Edward Teller, "one of the most brilliant and productive experimental physicists of the twentieth century" Luis Walter Alvarez, Murray Gell-Mann who introduced the quark, second female Nobel laureate Maria Goeppert-Mayer, the youngest American winner of the Nobel Prize Tsung-Dao Lee, and astrophysicist Subrahmanyan Chandrasekhar.
  11. Galileo realized that simple velocity addition demands that the concept of an "absolute rest frame" did not exist.
  12. With his mathematical insight, Sir Isaac Newton formulated laws of motion that were not improved-on for nearly three hundred years.
  13. Today, this is known as the Miasma theory.
  14. General relativity offers an equivalence between space-time and mass, but lacking a coherent theory of quantum gravity, it is unclear as to how or whether this connection is relevant on microscales.
  15. Dynamic equilibrium was first described by Galileo who noticed that certain assumptions of Aristotelian physics were contradicted by observations and logic.
  16. Through the work of leading theoretical physicists, a new theory of electromagnetism was developed using quantum mechanics.
  17. A Grand Unified Theory allowing for the combination of the electroweak interaction with the strong force is held out as a possibility with candidate theories such as supersymmetry proposed to accommodate some of the outstanding unsolved problems in physics.
  18. Michael Faraday and James Clerk Maxwell demonstrated that electric and magnetic forces were unified through one consistent theory of electromagnetism.
  19. Tesla was generally antagonistic towards theories about the conversion of matter into energy.
  20. Philosophers in antiquity used the concept of force in the study of stationary and moving objects and simple machines, but thinkers such as Aristotle and Archimedes retained fundamental errors in understanding force.
  21. Physicists are still attempting to develop self-consistent unification models that would combine all four fundamental interactions into a theory of everything.
  22. The development of fundamental theories for forces proceeded along the lines of unification of disparate ideas.
  23. This law is an extension of Galileo's insight that constant velocity was associated with a lack of net force (see a more detailed description of this below).
  24. This standard model of particle physics posits a similarity between the forces and led scientists to predict the unification of the weak and electromagnetic forces in electroweak theory subsequently confirmed by observation.
  25. A fundamental error was the belief that a force is required to maintain motion, even at a constant velocity.
