In phototypesetting, a photographic image is substituted for the conventional metal type. Reaching a height of more than miles kmthe V-2 marked the beginning of the space age, and members of its design team were instrumental in both the Soviet and U.
In the twentieth century there was a decline in deaths among young children and infants in China, East Asia and India. The steamboat and the Railroad were two important technologies of the nineteenth century that changed many aspects of life in India and Africa.
Working on his own in Britain, John Logie Baird in the s demonstrated a mechanical scanner able to convert an image into a series of electronic impulses that could then be reassembled on a viewing screen as a pattern of light and shade.
In venturing to interpret the events of the 20th century, it will be convenient to separate the years before from those that followed. In the United States the chemical industry provides some of the most striking examples of fully automated, computer-controlled manufacture. By the beginning of the 20th century, significant amounts of magnesium were being prepared electrolytically at high temperatures, and the electric furnace made possible the production of calcium carbide by the reaction of calcium oxide lime and carbon coke.
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.
An outstanding development of this type was the internal-combustion enginewhich was continuously improved to meet the needs of road vehicles and airplanes. The potential for adaptation and utilization of the computer seems so great that many commentators have likened it to the human brain, and there is no doubt that human analogies have been important in its development.
In the mids the attention of the U.
World War II marked the end of the primacy of the heavily armoured battleship. The refining of this material itself underwent important technological development. Although the United States recommissioned several battleships in the s, the aircraft carrier became the principal capital ship in the navies of the world.
Meanwhile, the size and power of launching rockets climbed steadily, and by the late s the enormous Saturn V rocket, standing feet metres high and weighing 2, tons 2, kilograms at lift-off, made possible the U.
While the extent of this transformation must not be overstated, and recent research has tended to stress the continuing need for the independent inventor at least in the stimulation of innovation, there can be little doubt that the change in the scale of technological enterprises had far-reaching consequences.
But already by the cinema and the radio had demonstrated their power in communicating news, propagandacommercial advertisements, and entertainment. The real novelties in communications in the 20th century came in electronics. The manned lunar exploration thus begun continued with a widening range of experiments and achievements for a further five landings before the program was curtailed in Africa and India experienced a deeper affect of technological transfer because they were conquered and colonized by Europe.
The outstanding feature of this refinement was its ability to amplify a signal. This astonishing achievement was stimulated in part by the international ideological rivalry already mentioned, as only the Soviet Union and the United States had both the resources and the will to support the huge expenditures required.
It threatened their individual autonomy because they were no longer masters of the work of their hands, but rather more like cogs in a large machine performing a limited set of functions, and not responsible for the whole.
The two World Wars were themselves the most important instruments of technological as well as political change in the 20th century. Leading into the twentieth century even though many would like to fast forward into the dawn of electronics, there is still a major focus on technology in Africa and Asia.
In the first stainless steels were made in England by alloying steel with chromium, and the Krupp works in Germany produced stainless steel in with 18 percent chromium and 8 percent nickel. Synthetic fertilizersan important product of the chemical industry, became popular in most types of farmingand other chemicals—pesticides and herbicides—appeared toward the end of the period, effecting something of an agrarian revolution.
Meanwhile, nuclear 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.
In most of these cases the development began before the 20th century, but the continuing increase in demand for these metals is affecting their prices in the world commodity markets.
Materials The space age spawned important new materials and uncovered new uses for old materials. Mariner and Viking probe series. Nevertheless, some important new techniques appeared sincenotably the use of heavy earth-moving and excavating machines such as the bulldozer and the tower crane.
The revolution in home equipment that began before World War II has continued apace since, with a proliferation of electrical equipment. Throughout the 19th century, to go back no further, investigations into aerodynamic effects were carried out by inventors such as Sir George Cayley in England, leading to the successful glider flights of Otto Lilienthal and others.
Later probes of the Venera series gathered further atmospheric and surficial data. This was an essential element of the industrialization that advanced throughout the 19th century.
Plastics The quality of plasticity is one that had been used to great effect in the crafts of metallurgy and ceramics. The discovery in of the first aniline dye had been occasioned by a vain attempt to synthesize quinine from coal tar derivatives.
Early equipment was crude, but within a few years striking progress was made in improving the means of transmitting and receiving coded messages. As with Britain in the Industrial Revolutionthe technological vitality of the United States in the 20th century was demonstrated less by any particular innovations than by its ability to adopt new ideas from whatever source they come.
Progress was being made simultaneously with the sulfonal hypnotics and the barbiturate group of drugs, and early in the 20th century Paul Ehrlich of Germany successfully developed an organic compound containing arsenic—, denoting how many tests he had made, but better known as Salvarsan —which was effective against syphilis.The Influence of Technology Advancemets in the Past 19th and 20th Century on Human’s Lifestyle ( words, 2 pages) The late 19th and 20th centuries have seen advances in technology and scientific understanding the likes of which have not been seen before in.
