Timeline of classical mechanics

Template:Classical mechanics The following is a timeline of the history of classical mechanics:

Antiquity

• 4th century BC – Aristotle invents the system of Aristotelian physics, which is later largely disproved
• 4th century BC – Babylonian astronomers calculate Jupiter's position using the Trapezoidal rule
• 260 BC – Archimedes works out the principle of the lever and connects buoyancy to weight
• 60 – Hero of Alexandria writes Metrica, Mechanics (on means to lift heavy objects), and Pneumatics (on machines working on pressure)
• 350 – Themistius states, that static friction is larger than kinetic friction

Early mechanics

• 6th century – John Philoponus introduces the concept of impetus and the theory was modified by Avicenna in the 11th century and Ibn Malka al-Baghdadi in the 12th century
• 6th century – John Philoponus says that by observation, two balls of very different weights will fall at nearly the same speed. He therefore tests the equivalence principle
• 1021 – Al-Biruni uses three orthogonal coordinates to describe point in space
• 1100–1138 – Avempace develops the concept of a fatigue, which according to Shlomo Pines is precursor to Leibnizian idea of force
• 1100–1165 – Hibat Allah Abu'l-Barakat al-Baghdaadi discovers that force is proportional to acceleration rather than speed, a fundamental law in classical mechanics

• 1340–1358 – Jean Buridan develops the theory of impetus
• 14th century – Oxford Calculators and French collaborators prove the mean speed theorem
• 14th century – Nicole Oresme derives the times-squared law for uniformly accelerated change. Oresme, however, regarded this discovery as a purely intellectual exercise having no relevance to the description of any natural phenomena, and consequently failed to recognise any connection with the motion of accelerating bodies
• 1500–1528 – Al-Birjandi develops the theory of "circular inertia" to explain Earth's rotation
• 16th century – Francesco Beato and Luca Ghini experimentally contradict Aristotelian view on free fall.
• 16th century – Domingo de Soto suggests that bodies falling through a homogeneous medium are uniformly accelerated. Soto, however, did not anticipate many of the qualifications and refinements contained in Galileo's theory of falling bodies. He did not, for instance, recognise, as Galileo did, that a body would fall with a strictly uniform acceleration only in a vacuum, and that it would otherwise eventually reach a uniform terminal velocity
• 1581 – Galileo Galilei notices the timekeeping property of the pendulum
• 1589 – Galileo Galilei uses balls rolling on inclined planes to show that different weights fall with the same acceleration
• 1638 – Galileo Galilei publishes Dialogues Concerning Two New Sciences (which were materials science and kinematics) where he develops, amongst other things, Galilean transformation
• 1644 – René Descartes suggests an early form of the law of conservation of momentum
• 1645 – Ismaël Bullialdus argues that "gravity" weakens as the inverse square of the distance
• 1651 – Giovanni Battista Riccioli and Francesco Maria Grimaldi discover the Coriolis effect
• 1658 – Christiaan Huygens experimentally discovers that balls placed anywhere inside an inverted cycloid reach the lowest point of the cycloid in the same time and thereby experimentally shows that the cycloid is the tautochrone
• 1668 – John Wallis suggests the law of conservation of momentum
• 1673 – Christiaan Huygens publishes his Horologium Oscillatorium. Huygens describes in this work the first two laws of motion. The book is also the first modern treatise in which a physical problem (the accelerated motion of a falling body) is idealized by a set of parameters and then analyzed mathematically.
• 1676–1689 – Gottfried Leibniz develops the concept of vis viva, a limited theory of conservation of energy
• 1677 – Baruch Spinoza puts forward a primitive notion of Newton's first law
