  2. Kepler's laws of planetary motion - Wikipedia

    en.wikipedia.org/wiki/Kepler's_laws_of_planetary...

    The second law establishes that when a planet is closer to the Sun, it travels faster. The third law expresses that the farther a planet is from the Sun, the longer its orbital period. Isaac Newton showed in 1687 that relationships like Kepler's would apply in the Solar System as a consequence of his own laws of motion and law of universal ...

  3. Occam's razor - Wikipedia

    en.wikipedia.org/wiki/Occam's_razor

    There are, however, notable exceptions where Occam's razor turns a conservative scientist into a reluctant revolutionary. For example, Max Planck interpolated between the Wien and Jeans radiation laws and used Occam's razor logic to formulate the quantum hypothesis, even resisting that hypothesis as it became more obvious that it was correct. [6]

  4. Special relativity - Wikipedia

    en.wikipedia.org/wiki/Special_relativity

    Special relativity corrects the hitherto laws of mechanics to handle situations involving all motions and especially those at a speed close to that of light (known as relativistic velocities). Today, special relativity is proven to be the most accurate model of motion at any speed when gravitational and quantum effects are negligible.

  5. Statute of limitations - Wikipedia

    en.wikipedia.org/wiki/Statute_of_limitations

    Common law legal systems can include a statute specifying the length of time within which a claimant or prosecutor must file a case. In some jurisdictions (e.g., California), [2] a case cannot begin after the period specified, and courts have no jurisdiction over cases filed after the statute of limitations has expired.

  6. Aristotle - Wikipedia

    Aristotle's laws of motion. In Physics he states that objects fall at a speed proportional to their weight and inversely proportional to the density of the fluid they are immersed in. [ 64 ] This is a correct approximation for objects in Earth's gravitational field moving in air or water.

  7. Mass–energy equivalence - Wikipedia

    If its temperature is allowed to change by 1 °C, its mass changes by 1.5 picograms (1 pg = 1 × 10 −12 g). [note 5] A spinning ball has greater mass than when it is not spinning. Its increase of mass is exactly the equivalent of the mass of energy of rotation, which is itself the sum of the kinetic energies of all the moving parts of the ball.

  8. Artificial intelligence - Wikipedia

    en.wikipedia.org/wiki/Artificial_intelligence

    Artificial intelligence (AI), in its broadest sense, is intelligence exhibited by machines, particularly computer systems.It is a field of research in computer science that develops and studies methods and software that enable machines to perceive their environment and use learning and intelligence to take actions that maximize their chances of achieving defined goals.
