Text messaging existed in the s but was not widely used until the early s, when it became a cultural phenomenon. Meanwhile, The computer revolution of the 20th century physics was probing the even more promising possibilities of harnessing the power of nuclear fusionof creating the conditions in which simple atoms of hydrogen combine, with a vast release of energy, to form heavier atoms.
Sinclair had made his money on innovative electronic products such as calculators and radios. Baekelanda Belgian American inventor, introduced a new class of large molecules when he took out his patent for Bakelite in In particular, the rapid growth of television services, with their immense influence as media of mass communication, was built on foundations laid in the s and s, while the universal adoption of radar on ships and airplanes followed the invention of a device to give early warning of aerial attack.
However throughout the s, "getting online" entailed complicated configuration, and dial-up was the only connection type affordable by individual users; the present day mass Internet culture was not possible.
In other respects the two wars hastened the development of technology by extending the institutional apparatus for the encouragement of innovation by both the state and private industry.
During the late s, photographs from Mariner orbiters demonstrated a close visual resemblance between the surface of Mars and that of the Moon. It should be observed also that technological innovations transformed the character of war itself. Again, the first achievement was Soviet: Longer-term solutions may be provided by the development of air-cushion vehicles derived from the Hovercraftin use in the English Channel and elsewhere, and one of the outstanding technological innovations of the period since Even more expressive of the character of the period was the leap over the threshold of extraterrestrial exploration.
The greater scale and complexity of urban life created a pressure for increased production and a greater variety of foodstuffs, and the resources of the internal-combustion engine, electricity, and chemical technology were called upon to achieve these objectives.
By the use of various catalysts in the process, means were devised for still further manipulating the molecules of the hydrocarbon raw material. The outstanding feature of this refinement was its ability to amplify a signal.
The techniques of rocketry, first applied in weapons, were developed to provide launch vehicles for satellites and lunar and planetary probes and eventually, into set the first men on the Moon and bring them home safely again. In the s and s, the military, governments and other organizations had computer systems.
The third stage of space exploration was the lunar program, beginning with approaches to the Moon and going on through automatic surveys of its surface to manned landings. It will soon be one of the first manufacturers of computer systems based on the bit Intel processor and a crucial player in the history of the industry, even a cautionary tale.
Far more sophisticated software should be widely used at roughly the same time, such as expert systems, automatically generated programming, personal assistants, and programs that enable computers to talk and to learn. Such forces were deployed in wars in Korea and Vietnam, the latter of which also saw the widespread use of napalm bombs and chemical defoliants to remove the cover provided by dense forests.
Military technology It has been necessary to refer repeatedly to the effects of the two World Wars in promoting all kinds of innovation.
Bakelite is made by the reaction between formaldehyde and phenolic materials at high temperatures; the substance is hard, infusible, and chemically resistant the type known as thermosetting plastic.
This new development heralded an explosion in the commercial and personal use of computers and led to the invention of the microprocessor. Civil engineering One industry that has not been deeply influenced by new control-engineering techniques is construction, in which the nature of the tasks involved makes dependence on a large labour force still essential, whether it be in constructing a skyscraper, a new highway, or a tunnel.
It also had modules to multiply, divide, and square root. The first such material to be manufactured was Parkesinedeveloped by the British inventor Alexander Parkes. Manganese steel is also nonmagnetic; this fact suggests great possibilities for this steel in the electric power industry.
The essence of this machine is the use of electronic devices to record electric impulses coded in the very simple binary system, using only two symbols, but other devices such as punched cards and magnetic tape for storing and feeding information have been important supplementary features.
Simultaneously, a group of German and Romanian pioneers was working along the same lines, and it was this team that was taken over by the German war effort in the s and given the resources to develop a rocket capable of delivering a warhead hundreds of miles away.
An outstanding development of this type was the internal-combustion enginewhich was continuously improved to meet the needs of road vehicles and airplanes. These weapons underwent momentous development: The Antikythera mechanism is believed to be the earliest mechanical analog "computer", according to Derek J.
At the beginning of the 19th century, Davy pioneered the process by isolating potassium, sodium, barium, calcium, and strontium, although there was little commercial exploitation of these substances.
Petroleum As far as fuel is concerned, the gas turbine burns mainly the middle fractions kerosene, or paraffin of refined oil, but the general tendency of its widespread application was to increase still further the dependence of the industrialized nations on the producers of crude oilwhich became a raw material of immense economic value and international political significance.
These so-called smartphones and tablets run on a variety of operating systems and have become the dominant computing device on the market, with manufacturers reporting having shipped an estimated million devices in 2Q Despite such problems, farming was transformed in response to the demand for more food; scientific farming, with its careful breeding, controlled feeding, and mechanized handling, became commonplace.
The term is often used as a commercial vehicle, though often violating the Open Source Definition itself. Communications The spectacular transport revolution of the 20th century was accompanied by a communications revolution quite as dramatic, although technologically springing from different roots.
The first artificial textiles had been made from rayona silklike material produced by extruding a solution of nitrocellulose in acetic acid into a coagulating bath of alcohol, and various other cellulosic materials were used in this way.
Ever larger and more powerful gas turbines were designed to meet the requirements of airlines and military strategy, and increasing attention was given to refinements to reduce the noise and increase the efficiency of this type of engine.
Production rose rapidly since. The idea of the integrated circuit was first conceived by a radar scientist working for the Royal Radar Establishment of the Ministry of DefenceGeoffrey W.
But in certain features the development of communications in the space age has produced important innovations.20th Century Timeline - 20th Century — the Technology, Science, and Inventions. Share Flipboard or analog computer invented by Vannevar Bush at MIT in Boston.

Get started now! The spectacular transport revolution of the 20th century was accompanied by a communications revolution quite as dramatic, although technologically springing from different roots. especially the electronic digital computer, a 20th-century invention the theory of which was expounded by the English mathematician and inventor Charles.
The Digital Revolution, the latter half of the 20th century. Analogous to the Agricultural Revolution and Industrial Revolution, By15% of all U.S. households owned a computer, and nearly 30% of households with children under the age of 18 owned one.
A computer is a device that can be instructed to carry out sequences of arithmetic or logical operations automatically via Early in the Industrial Revolution, More sophisticated electrical machines did specialized analog calculations in the early 20th century.
The first digital electronic calculating machines were developed during.Download
