Timeline of invention
Significant modern inventions, arranged in chronological order Note: Dates for inventions are often controversial. Inventions are often invented by several inventors around the same time, or may be invented in an impractical form many years before another inventor improves the invention into a practical form. Where there is ambiguity, the date of the first practical, fielded, version of the invention should be used here. 7th millennium BC * Pottery * fabric * the wedge 4th millennium BC: picto-linguistic writing early 3rd millennium BC * Bronze * Sumerian picto-graphic writing * tents * cultivation of grains * domestication of animals * pictograms * sledges - Scandinavia * the wheel and wheeled vehicles * levers * pure samples of carbon, copper, iron , gold, mercury , lead, silver, sulphur tin and zinc in use * the plow 35th century BC * irrigation -Ancient Egypt * surveying 32nd century BC: Egyptian hieroglyphics 31st century BC * Chinese ideograms * Drainage and Sewage system in India * Dams, canals, stone sculptures using inclined plane and lever in Sumeria * Pyramids in Ancient Egypt. 23rd century BC * clay maps in Babylon 22nd century BC * Babylonian calendar modifications to account for the precession of the stars * True astrolonomical observation - Mesopotamia * Spherical geometry in Babylon 21st century BC: Cretan writing 19th century BC * Babylonian cuneiform * Code of Hammurabi - invention of codified municipal law 18th century BC: Linear A - Hagia Triada 16th century BC: Phonetic spelling developed by Phoenicians 15th century BC: Linear B - mainland Greece or Knossus 10th century BC: Rustproof Iron - India 7th century BC: Coinage, Discovery of irrational numbers 460s BC : First atomic theory - Democritus 410s BC: heliocentric solar system with spherical Sun ,Moon, Venus, Mercury, Mars, Jupiter, Saturn - Philolaus 400s BC:Catapults in Syracuse 350s BC: rotation of Earth -Hereclides 225s BC: measurement of Circumference of the Earth - Eratosthenes 220s BC * Archimedes o Specific gravity o concept of limit o Archimedean solids o false attribution of hydraulic screw pump as archimedes screw o parabolic mirror * Compass - a south pointing spoonlike lodestone in Han dynasty. 150s BC: Astrolabe - Hipparchus 100s BC: Glass-blowing in Syria 1st century * differential gear (the antikythera mechanism 2nd century * 105: paper: Ts'ai Lun 7th century * 700 - Windmills in Persia 10th century * Gunpowder (in China: some ref says 8th century?) 11th century * 1045 - movable type printing by Bi Sheng in China (before Gutenberg) * 1050 - Crossbow in France 13th century * 1249: Gunpowder formula: Roger Bacon 14th century * 1346: Cannon in wide use 15th century * 15th century: Rifle * 1450: Moveable type: Johann Gutenberg * 1480: Nautical astrolabe: Martin Behaim * 1480: Parachute: Leonardo da Vinci 16th century * 1593: Thermometer: Galileo Galilei * 1595: Microscope: Zacharias Janssen 17th century * 1608: Refracting telescope: Hans Lippershey * 1609: Telescope: Galileo Galilei * 1611: Telescope: Johannes Kepler * 1620: Slide rule: William Oughtred * 1642: Adding machine: Blaise Pascal * 1643: Barometer: Evangelista Torricelli * 1645: Vacuum pump: Otto von Guericke * 1657: Pendulum clock: Christiaan Huygens 18th century * 1705: Engine - steam piston: Thomas Newcomen * 1709: Piano: Bartolomeo Cristofori * 1710: Thermometer: RenŽ Antoine Ferchault de RŽaumur * 1714: Mercury thermometer: Daniel Gabriel Fahrenheit * 1730: Mariner's quadrant: Thomas Godfrey * 1731: Sextant: John Hadley * 1733: Flying shuttle: John Kay * 1742: Franklin stove: Benjamin Franklin * 1750: Flatboat: Jacob Yoder * 1752: Lightning rod: Benjamin Franklin * 1762: Iron smelting process: Jared Eliot * 1767: Spinning Jenny: James Hargreaves * 1769: Steam engine: James Watt * 1775: Submarine The Turtle: David Bushnell * 1777: Card making machine: Oliver Evans * 1777: Circular saw: Samuel Miller * 1779: Spinning Mule: Samuel Crompton * 1785: Power loom: Edmund Cartwright * 1785: Automatic flour mill: Oliver Evans * 1783: Multitubular boiler engine: John Stevens * 1783: Bifocals: Benjamin Franklin * 1783: Hot air balloon: Montgolfier brothers * 1784: Shrapnel shell: Henry Shrapnel * 1785: Parachute: Jean Pierre Blanchard * 1787: Non-condensing high pressure Engine: Oliver Evans * 1791: Steamboat: John Fitch * 1790: Cut and head nail machine: Jacob Perkins * 1793: Cotton Gin: Eli Whitney * 1793: Moldboard plow: Thomas Jefferson * 1793: Optical telegraph: Claude Chappe * 1797: Cast iron plow: Charles Newbold * 1798: Vaccination: Edward Jenner * 1799: Seeding machine: Eliakim Spooner 19th century 1800s * 1800: Electric battery: Alessandro Volta * 1802: Screw propeller steamboat Phoenix: John Stevens * 1805: Torpedo: Robert Fulton * 1805: Refrigerator: Oliver Evans * 1807: Steamboat Clermont: Robert Fulton * 1808: Band saw: William Newberry 1810s * 1811: Gun- Breechloader: Thornton (?) * 1816: Miner's safety lampDavy lamp:Humphry Davy * 1816: Hand printing press: George Clymer * 1816: Metronome: Johann Nepomuk Maelzel (reputed) * 1817: Kaleidoscope: David Brewster * 1819: Breech loading flintlock: John Hall * 1819: Stethoscope: Rene Theophile Hyacinthe Laennec 1820s * 1822: Artificial teeth: C.M.
