As the Paleolithic era progressed, dwellings became more sophisticated and more elaborate; as early as ka, humans were constructing temporary wood huts. The invention of polished stone axes was a major advance that allowed forest clearance on a large scale to create farms.

This use of polished stone axes increased greatly in the Neolithic, but were originally used in the preceding Mesolithic in some areas such as Ireland.

Additionally, children could contribute labor to the raising of crops more readily than they could to the hunter-gatherer economy. Eventually, the working of metals led to the discovery of alloys such as bronze and brass about BCE.

The first uses of iron alloys such as steel dates to around BCE. History of transport Meanwhile, humans were learning to harness other forms Technology of 21 century essay energy. The earliest known use of wind power is the sailing ship ; the earliest record of a ship under sail is that of a Nile boat dating to the 8th millennium BCE.

The ancient Sumerians in Mesopotamia used a complex system of canals and levees to divert water from the Tigris and Euphrates rivers for irrigation.

More recently, the oldest-known wooden wheel in the world was found in the Ljubljana marshes of Slovenia.

It did not take long to discover that wheeled wagons could be used to carry heavy loads. The first two-wheeled carts were derived from travois [61] and were first used in Mesopotamia and Iran in around BCE. Medieval technologyRenaissance technologyIndustrial RevolutionSecond Industrial RevolutionInformation Technologyand Productivity improving technologies Technology of 21 century essay history Innovations continued through the Middle Ages with innovations such as silkthe horse collar and horseshoes in the first few hundred years after the fall of the Roman Empire.

Medieval technology saw the use of simple machines such as the leverthe screwand the pulley being combined to form more complicated tools, such as the wheelbarrowwindmills and clocks.

The Renaissance brought forth many of these innovations, including the printing press which facilitated the greater communication of knowledgeand technology became increasingly associated with sciencebeginning a cycle of mutual advancement.

The advancements in technology in this era allowed a more steady supply of food, followed by the wider availability of consumer goods. The automobile revolutionized personal transportation.

Starting in the United Kingdom in the 18th century, the Industrial Revolution was a period of great technological discovery, particularly in the areas of agriculturemanufacturingminingmetallurgyand transportdriven by the discovery of steam power. Technology took another step in a second industrial revolution with the harnessing of electricity to create such innovations as the electric motorlight bulband countless others.

Scientific advancement and the discovery of new concepts later allowed for powered flight and advancements in medicinechemistryphysicsand engineering. The rise in technology has led to skyscrapers and broad urban areas whose inhabitants rely on motors to transport them and their food supply.

Communication was also greatly improved with the invention of the telegraphtelephoneradio and television. The late 19th and early 20th centuries saw a revolution in transportation with the invention of the airplane and automobile. F and F flying over Kuwaiti oil fires during the Gulf War in The 20th century brought a host of innovations.

In physicsthe discovery of nuclear fission has led to both nuclear weapons and nuclear power. Computers were also invented and later miniaturized utilizing transistors and integrated circuits. Information technology subsequently led to the creation of the Internetwhich ushered in the current Information Age.

Humans have also been able to explore space with satellites later used for telecommunication and in manned missions going all the way to the moon. In medicine, this era brought innovations such as open-heart surgery and later stem cell therapy along with new medications and treatments.

Complex manufacturing and construction techniques and organizations are needed to make and maintain these new technologies, and entire industries have arisen to support and develop succeeding generations of increasingly more complex tools.

Moreover, these technologies have become so complex that entire fields have been created to support them, including engineeringmedicineand computer scienceand other fields have been made more complex, such as constructiontransportationand architecture.

Philosophy Technicism Generally, technicism is the belief in the utility of technology for improving human societies.

Some, such as Stephen V. Monsma, [68] connect these ideas to the abdication of religion as a higher moral authority. Extropianism Optimistic assumptions are made by proponents of ideologies such as transhumanism and singularitarianismwhich view technological development as generally having beneficial effects for the society and the human condition.

In these ideologies, technological development is morally good. Transhumanists generally believe that the point of technology is to overcome barriers, and that what we commonly refer to as the human condition is just another barrier to be surpassed.

Singularitarians believe in some sort of " accelerating change "; that the rate of technological progress accelerates as we obtain more technology, and that this will culminate in a " Singularity " after artificial general intelligence is invented in which progress is nearly infinite; hence the term.

Estimates for the date of this Singularity vary, [69] but prominent futurist Ray Kurzweil estimates the Singularity will occur in Kurzweil is also known for his history of the universe in six epochs: Going from one epoch to the next is a Singularity in its own right, and a period of speeding up precedes it.Turnitin provides instructors with the tools to prevent plagiarism, engage students in the writing process, and provide personalized feedback.
