Later probes of the Venera series gathered further atmospheric and surficial data. But the stimulus of World War II gave a fresh urgency to research in this field, and commercial production of penicillin, the first of the antibiotics, began in The digital revolution became truly global in this time as well - after revolutionizing society in the developed world in the s, the digital revolution spread to the masses in the developing world in the s.
A series of Soviet and U. Space-age technology The years since World War II ended have been spent in the shadow of nuclear weapons, even though they have not been used in war since that time. Millions of people purchased home computers, making household names of early personal computer manufacturers such as Apple, Commodore, and Tandy.
In many countries, especially in Europe, the movement was channeled into politics through Green parties. The small direct-current generators of early urban power systems were abandoned in favour of alternating-current systems, which could be adapted more readily to high voltages.
The rapid development of the airplane, the cinema, and radio made the world seem suddenly smaller and more accessible. In the so-called ramjet engine, intended to operate at high speeds, the momentum of the engine through the air achieves adequate compression.
The science of pharmacy emerged slowly from the traditional empiricism of the herbalist, but by the end of the 19th century there had been some solid achievements in the analysis of existing drugs and in the preparation of new ones.
Rapid technological advancements, however, also allowed warfare to reach unprecedented levels of destruction. Fuel and power There were no fundamental innovations in fuel and power before the breakthrough ofbut there were several significant developments in techniques that had originated in the previous century.
Digital computers It has been suggested that this section be split out into another article titled Digital computer. An outstanding development of this type was the internal-combustion enginewhich was continuously improved to meet the needs of road vehicles and airplanes.
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.
In Japan, where computer and other electronics technology made giant strides since the s, fully computerized and automated factories were in operation by the mids, some of them employing complete workforces of robots in the manufacture of other robots. The use of large concrete members in bridges and other structures has been made possible by the technique of prestressing: The airplane, benefiting from jet propulsion and a number of lesser technical advances, made spectacular gains at the expense of both the ocean liner and the railroad.
Transportation Some of the outstanding achievements of the 20th century are provided by transportation history. At the beginning of the century, strong discrimination based on race and sex was significant in general society. 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.
The first such material to be manufactured was Parkesinedeveloped by the British inventor Alexander Parkes. Plastics The quality of plasticity is one that had been used to great effect in the crafts of metallurgy and ceramics.
Sixth, new physical techniques such as those that produced the laser light amplification by stimulated emission of radiation made available an immensely powerful means of communication over long distances, although these are still in their experimental stages.
Transistorized computers could contain tens of thousands of binary logic circuits in a relatively compact space. A combination of the planisphere and dioptrathe astrolabe was effectively an analog computer capable of working out several different kinds of problems in spherical astronomy.
They had devised a system of control through elevator, rudder, and a wing-warping technique that served until the introduction of ailerons.
The war led the Manhattan Project to produce the fission bomb that was first exploded at Alamogordo, N. The significance of this discovery, made inwas that was the first drug devised to overwhelm an invading microorganism without offending the host.
By the end of the 20th century, women had the same legal rights as men in many parts of the world, and racism had come to be seen as abhorrent. THE first industrial revolution began in Britain in the late 18th century, with the mechanisation of the textile industry.
Tasks previously done laboriously by hand in hundreds of weavers. Who was the greatest computer scientist of the 20th century? Update Cancel. ad by Lambda Labs The founfer of free softwsre revolution and the maker of GNU.

Who are. You can forget inventions like air conditioning, television, the computer and the Internet. The single most important invention of the 20th.
Beyond the Basics: Calculators in the 20th Century. Calculators weren’t keeping up. Business and science, engineering and commerce, factories and insurance companies all expanded rapidly in the Industrial Revolution. You can forget inventions like air conditioning, television, the computer and the Internet.
The single most important invention of the 20th century was the transistor, according to some.
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.The computer revolution of the 20th century
