The timeline of historic inventions is a chronological list of particularly important or significant technological inventions and their inventors, where known. [lower-alpha 1]
History of technology |
---|
The dates listed in this section refer to the earliest evidence of an invention found and dated by archaeologists (or in a few cases, suggested by indirect evidence). Dates are often approximate and change as more research is done, reported and seen. Older examples of any given technology are often found. The locations listed are for the site where the earliest solid evidence has been found, but especially for the earlier inventions, there is little certainty how close that may be to where the invention took place.
The Lower Paleolithic period lasted over 3 million years, during which there many human-like species evolved including toward the end of this period, Homo sapiens. The original divergence between humans and chimpanzees occurred 13 (Mya), however interbreeding continued until as recently as 4 Ma, with the first species clearly belonging to the human (and not chimpanzee) lineage being Australopithecus anamensis . Some species are controversial among paleoanthropologists, who disagree whether they are species on their own or not. Here Homo ergaster is included under Homo erectus, while Homo rhodesiensis is included under Homo heidelbergensis.
During this period the Quaternary glaciation began (about 2.58 million years ago), and continues to today. It has been an ice age, with cycles of 40–100,000 years alternating between long, cold, more glaciated periods, and shorter warmer periods – interglacial episodes.
The dawn of Homo sapiens around 300 kya coincides with the start of the Middle Paleolithic period. Towards the middle of this 250,000-year period, archaic humans such as Neanderthals and Denisovans began to spread out of Africa, joined later by Homo Sapiens. Also late in the period, we have increased evidence of long-distance trade, religious rites, and other behavior associated with Behavioral modernity.
50 kya was long regarded as the beginning of behavioral modernity, which defined the Upper Paleolithic period. The upper Paleolithic lasted nearly 40,000 years, while research continues to push the beginnings of behavioral modernity earlier into the Middle Paleolithic. Behavioral modernity is characterized by the widespread observation of religious rites, artistic expression and the appearance of tools made for purely intellectual or artistic pursuits.
The end of the Last Glacial Period ("ice age") and the beginning of the Holocene around 11.7 ka coincide with the Agricultural Revolution, marking the beginning of the agricultural era, which persisted there until the industrial revolution. [82]
During the Neolithic period, lasting 8400 years, stone began to be used for construction, and remained a predominant hard material for toolmaking. Copper and arsenic bronze were developed towards the end of this period, and of course the use of many softer materials such as wood, bone, and fibers continued. Domestication spread both in the sense of how many species were domesticated, and how widespread the practice became.
The beginning of bronze-smelting coincides with the emergence of the first cities and of writing in the Ancient Near East and the Indus Valley. The Bronze Age starting in Eurasia in the 4th millennia BC and ended, in Eurasia, c.1200 BC.
The Late Bronze Age collapse occurs around 1200 BC, [204] extinguishing most Bronze-Age Near Eastern cultures, and significantly weakening the rest. This is coincident with the complete collapse of the Indus Valley Civilisation. This event is followed by the beginning of the Iron Age. We define the Iron Age as ending in 510 BC for the purposes of this article, even though the typical definition is region-dependent (e.g. 510 BC in Greece, 322 BC in India, 200 BC in China), thus being an 800-year period.

Advances in the isolation and sequencing of ancient DNA [... suggest] that dogs were domesticated in Siberia by ~23,000 y ago, possibly while both people and wolves were isolated during the harsh climate of the Last Glacial Maximum.
It appears that two artifacts from Mohenjadaro and Harappa might correspond to these two instruments. Joshi and Parpola (1987) lists a few pots tapered at the bottom and having a hole on the side from the excavations at Mohenjadaro (Figure 3). A pot with a small hole to drain the water is very similar to clepsydras described by Ohashi to measure the time (similar to the utensil used over the lingum in Shiva temple for abhishekam).
As already mentioned, the textual evidence for Sumero-Babylonian distillation is disclosed in a group of Akkadian tablets describing perfumery operations, dated ca. 1200 B.C.
In ancient India, loan deed forms called rnapatra or rnalekhya were in use. These contained details such as the name of the debtor and the creditor, the amount of loan, the rate of interest, the condition of repayment and the time of repayment. The deed was witnessed by a person of respectable means and endorsed by the loan-deed writer. Execution of loan deeds continued during the Buddhist period, when they were called inapanna.
Developed in China between the fifth and fourth centuries BC, it reached the Mediterranean by the sixth century AD
In the Mauryan period, an instrument called adesha was in use, which was an order on a banker desiring him to pay the money of the note to a third person
The earliest known analog computing device is the Antikythera mechanism.
The first improvement in spinning technology was the spinning wheel, which was invented in India between 500 and 1000 A.D.
...not more than a few days passed before the craftsman, to whom the construction of this contrivance had been described, brought in the pen, fashioned from gold. He then filled it with ink and wrote with it, and it really did write. The pen released a little more ink than was necessary. Hence al-Mu'izz ordered that it should be adjusted slightly, and he did this. He brought forward the pen and behold, it turned out to be a pen which can be turned upside down in the hand and tipped from side to side, and no trace of ink appears from it. When a secretary takes up the pen and writes with it, he is able to write in the most elegant script that could possibly be desired; then, when he lifts the pen off the sheet of writing material, it holds in the ink. I observed that it was a wonderful piece of work, the like of which I had never imagined I would ever see.

The first packet-switching network was implemented at the National Physical Laboratories in the United Kingdom. It was quickly followed by the ARPANET in 1969.
Leonard Kleinrock: Donald Davies ... did make a single node packet switch before ARPA did
The NPL group influenced a number of American computer scientists in favor of the new technique, and they adopted Davies's term "packet switching" to refer to this type of network. Roberts also adopted some specific aspects of the NPL design.
In nearly all respects, Davies' original proposal, developed in late 1965, was similar to the actual networks being built today.
The design of the ARPA network (ArpaNet) was entirely changed to adopt this technique.; "Donald Davies". www.internethalloffame.org. Retrieved 20 April 2022.
the ARPANET received his network design enthusiastically and the NPL local network became the first two computer networks in the world using the technique.
Historians credit seminal insights to Welsh scientist Donald W. Davies and American engineer Paul Baran
The authors wish to thank a number of colleagues for helpful comments during early discussions of international network protocols, especially R. Metcalfe, R. Scantlebury, D. Walden, and H. Zimmerman; D. Davies and L. Pouzin who constructively commented on the fragmentation and accounting issues; and S. Crocker who commented on the creation and destruction of associations.
In the early 1970s Mr Pouzin created an innovative data network that linked locations in France, Italy and Britain. Its simplicity and efficiency pointed the way to a network that could connect not just dozens of machines, but millions of them. It captured the imagination of Dr Cerf and Dr Kahn, who included aspects of its design in the protocols that now power the internet.
He wove the World Wide Web and created a mass medium for the 21st century. The World Wide Web is Berners-Lee's alone. He designed it. He loosed it on the world. And he more than anyone else has fought to keep it open, nonproprietary and free.
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, airship, or other vehicle that moves through a fluid medium. On an airplane, the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
A water clock or clepsydra is a timepiece by which time is measured by the regulated flow of liquid into or out from a vessel, and where the amount of liquid can then be measured.
A cradle of civilization is a location and a culture where civilization was developed independent of other civilizations in other locations. A civilization is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages.
The history of technology is the history of the invention of tools and techniques by humans. Technology includes methods ranging from simple stone tools to the complex genetic engineering and information technology that has emerged since the 1980s. The term technology comes from the Greek word techne, meaning art and craft, and the word logos, meaning word and speech. It was first used to describe applied arts, but it is now used to describe advancements and changes that affect the environment around us.
The Four Great Inventions are inventions from ancient China that are celebrated in Chinese culture for their historical significance and as symbols of ancient China's advanced science and technology. They are the compass, gunpowder, papermaking and printing.
Science in the ancient world encompasses the earliest history of science from the protoscience of prehistory and ancient history to late antiquity. In ancient times, culture and knowledge were passed through oral tradition. The development of writing further enabled the preservation of knowledge and culture, allowing information to spread accurately.
During the growth of the ancient civilizations, ancient technology was the result from advances in engineering in ancient times. These advances in the history of technology stimulated societies to adopt new ways of living and governance.
Agriculture began independently in different parts of the globe, and included a diverse range of taxa. At least eleven separate regions of the Old and New World were involved as independent centers of origin. The development of agriculture about 12,000 years ago changed the way humans lived. They switched from nomadic hunter-gatherer lifestyles to permanent settlements and farming.
Ferrous metallurgy is the metallurgy of iron and its alloys. The earliest surviving prehistoric iron artifacts, from the 4th millennium BC in Egypt, were made from meteoritic iron-nickel. It is not known when or where the smelting of iron from ores began, but by the end of the 2nd millennium BC iron was being produced from iron ores in the region from Greece to India, The use of wrought iron was known by the 1st millennium BC, and its spread defined the Iron Age. During the medieval period, smiths in Europe found a way of producing wrought iron from cast iron, in this context known as pig iron, using finery forges. All these processes required charcoal as fuel.
Ancient Chinese scientists and engineers made significant scientific innovations, findings and technological advances across various scientific disciplines including the natural sciences, engineering, medicine, military technology, mathematics, geology and astronomy.
Chinese exploration includes exploratory Chinese travels abroad, on land and by sea, from the travels of Han dynasty diplomat Zhang Qian into Central Asia during the 2nd century BC until the Ming dynasty treasure voyages of the 15th century that crossed the Indian Ocean and reached as far as East Africa.
This timeline of prehistory covers the time from the appearance of Homo sapiens approximately 315,000 years ago in Africa to the invention of writing, over 5,000 years ago, with the earliest records going back to 3,200 BC. Prehistory covers the time from the Paleolithic to the beginning of ancient history.
This timeline of ancient history lists historical events of the documented ancient past from the beginning of recorded history until the Early Middle Ages. Prior to this time period, prehistory civilizations were pre-literate and did not have written language.
The concept of engineering has existed since ancient times as humans devised fundamental inventions such as the pulley, lever, and wheel. Each of these inventions is consistent with the modern definition of engineering, exploiting basic mechanical principles to develop useful tools and objects.
The Tang dynasty (618–907) of ancient China witnessed many advancements in Chinese science and technology, with various developments in woodblock printing, timekeeping, mechanical engineering, medicine, and structural engineering.
The compass is a magnetometer used for navigation and orientation that shows direction in regards to the geographic cardinal points. The structure of a compass consists of the compass rose, which displays the four main directions on it: East (E), South (S), West (W) and North (N). The angle increases in the clockwise position. North corresponds to 0°, so east is 90°, south is 180° and west is 270°.
This is a timeline of the history of gunpowder and related topics such as weapons, warfare, and industrial applications. The timeline covers the history of gunpowder from the first hints of its origin as a Taoist alchemical product in China until its replacement by smokeless powder in the late 19th century.
