Definition and application
The printing press enabled scientists and politicians to easily disseminate their ideas, resulting in the Age of Enlightenment, which is an example of technology as a cultural force.
In general, technology refers to how civilization interacts with its tools and crafts, as well as how much influence it has over its surroundings. The Merriam-Webster dictionary defines the phrase as "the practical application of knowledge, particularly in a specific area," as well as "a capability conferred by the practical application of knowledge." Another definition given by Ursula Franklin in her 1989 "Real World of Technology" speech is "practise, the way we do things around here." The term is frequently used to denote a certain subject of study. This notion of technology includes virtual technology such as computer software and business procedures.
A combination of procedures can also be referred to as "technology." It refers to humanity's existing understanding of how to combine resources to create desired products, solve issues, meet requirements, or satisfy desires; it comprises technological procedures, skills, processes, techniques, tools, and raw materials. When used in conjunction with another term, such as "medical technology" or "space technology," it refers to the current state of knowledge and tools in the respective discipline. In any sector, "state-of-the-art technology" refers to the most advanced technology available to humanity.
Technology can be considered as a cultural forming or changing activity. Furthermore, technology is the use of math, science, and the arts for the betterment of life as we know it. A contemporary example is the growth of communication technology, which has lowered barriers to human interaction and, as a result, has aided in the emergence of new subcultures; the advent of cyberculture has, at its foundation, the development of the Internet and the computer. Technology precedes both science and engineering as a cultural activity, each of which formalizes various parts of technological endeavor.
Science, Technology, and Engineering
It's not always easy to tell the difference between science, engineering, and technology. By applying formal approaches such as the scientific method, science is the reasoned inquiry or study of occurrences with the goal of discovering enduring principles among aspects of the phenomenal world. Because they must meet standards such as utility, usability, and safety, technologies are rarely solely scientific creations.
Engineering is the goal-oriented process of creating and fabricating instruments and systems to utilize natural phenomena for practical human purposes, frequently (but not always) employing scientific findings and methodologies. To reach some practical result, technology development may depend on numerous kinds of knowledge, including scientific, engineering, mathematical, linguistic, and historical information.
Although technology as a human activity precedes science and engineering, it is sometimes a result of the two professions. For example, using existing instruments and expertise, science could investigate the flow of electrons in electrical conductors. Engineers can then use this newfound knowledge to construct new tools and machinery, such as semiconductors, computers, and other advanced technologies. In this sense, scientists and engineers are also technologists; the three fields are sometimes treated as one for research and reference reasons.
Historical significance
The translation of natural resources into rudimentary tools was the beginning of the human race's use of technology. The primordial discovery of the capacity to manage fire expanded the accessible food supplies, and the advent of the wheel aided humans in travelling through and controlling their surroundings. The printing press, the telephone, and the Internet are examples of recent technological advancements that have reduced physical barriers to communication and allowed humans to engage on a global scale. However, not all technology has been employed for peaceful reasons; from clubs to nuclear weapons, the invention of weapons with ever-increasing destructive potential has proceeded throughout history.
Paleolithic (2.5 million to 10,000 years ago)
A rudimentary chopper
Early humans' use of tools was partly a process of discovery, partly due to evolution Early humans descended from a group of foraging hominids who were already bipedal and had a brain mass roughly one-third that of contemporary humans. For most of early human history, tool use remained essentially constant, but around 50,000 years ago, a sophisticated set of behaviors and tool use arose, which many archaeologists believe is linked to the formation of fully-modern language.
Stone implements
Hand axes from the time of Acheulian
Pressure flaking was used to create a Clovis point.
Long before the birth of Homo sapiens roughly 200,000 years ago, human ancestors used stone and other tools.
The first methods of stone tool production, known as the Oldowan "industry," date back to at least 2.3 million years ago, with the earliest direct evidence of tool use reaching back to 2.5 million years ago in Ethiopia's Great Rift Valley. The Paleolithic, or "Old Stone Age," is the period of stone tool use that includes all of human history up to the invention of agriculture about 12,000 years ago.
A "core" of hard stone with certain flaking qualities (such as granite) is used to construct a stone tool.
A hammer stone was used to strike the flint. This flaking resulted in a sharp edge on both the core stone and the flakes, which could be utilize as tools in the form of choppers or scrapers. Early humans used these tools to execute a number of tasks, including butchering carcasses (including shattering bones to get at the marrow), chopping wood, cracking open nuts, skinning an animal for its hide, and even making other tools out of softer materials like bone and wood.
The first stone tools were crude, consisting largely of broken rock. Methods of shaping these stones into specific shapes, such as hand axes, arose during the Acheulian epoch, which began roughly 1.65 million years ago. Around 300,000 years ago, the Middle Paleolithic saw the introduction of the prepared-core technique, which allowed several blades to be quickly made from a single core stone. Pressure flaking, which began around 40,000 years ago and involved using a wood, bone, or antler punch to form a stone very finely, was introduced during the Upper Paleolithic.
Fire
The discovery and use of fire, a simple energy source with numerous applications, marked a turning point in human technological evolution.
Its exact date of discovery is unknown Burnt animal bones found at the Cradle of Humankind reveal that fire was domesticated before 1,000,000 B.C.E. ; scholarly consensus estimates that Homo erectus had control of fire between 500,000 and 400,000 B.C.E. Early people were able to cook their food with fire, which increased its digestibility, improved its nutritious value, and increased the amount of items they could eat.
Shelter and clothing
Clothing and shelter were two further technological improvements achieved during the Paleolithic era; their adoption cannot be pinpointed, but they were crucial to humanity's progress. Dwellings got more intricate and elaborate as the Paleolithic era proceeded; humans were building temporary wood shelters as early as 380,000 B.C.E. Clothing made from the fur and hides from hunted animals aided humanity's expansion into colder climates; by 200,000 B.C.E., humans had begun to migrate out of Africa and onto other continents, such as Eurasia.
Burins and racloirs made during this time period show that humans began to work bones, antlers, and hides.
(10,000 B.C.E. – 300 C.E.) Neolithic through Classical Antiquity
Bracelets, axe heads, chisels, and polishing tools are among the Neolithic antiquities on display.
In what is known as the Neolithic period, man's technological ascension began in earnest ("New Stone Age"). The creation of polished stone axes was a significant step forward, since it enabled for large-scale forest removal to construct farms. The discovery of agriculture enabled bigger people to be fed, and the change to a sedentism lifestyle increased the number of children that could be reared at the same time, as tiny children no longer required to be carried as they did in the nomadic lifestyle. Furthermore, children could more readily contribute labor to crop production than they could to the hunter-gatherer lifestyle.
Tools made of metal
The furnace and bellows were created as a result of continuous advances, allowing native metals to be smelted and forged (naturally occurring in relatively pure form). Such early metals included gold, copper, silver, and lead. Early people immediately recongnized the benefits of copper tools over stone, bone, and wooden implements, and native copper was most likely used from the Neolithic period onward (about 8000 B.C.E.). Copper does not occur in significant quantities in nature, but copper ores are abundant, and some of them burn quickly in wood or charcoal fires to generate metal. Working with metals eventually led to the creation of alloys like bronze and brass (about 4000 B.C.E.). Steel and iron alloys were used for the first time around 1400 B.C.E.
Transportation and Energy
Meanwhile, people were discovering new ways to harness energy. The sailboat is the first known application of wind power. The earliest evidence of a ship under sail can be found on an Egyptian pot from 3200 B.C.E. Egyptians have certainly employed "the force of the Nile" periodic floods to irrigate their lands from prehistoric times, eventually learning to control much of it through purpose-built irrigation channels and 'catch' basins. Similarly, the Sumerians, the first inhabitants of Mesopotamia, learned to use the Tigris and Euphrates rivers for similar purposes. However, increasingly widespread usage of wind, water, and even human power necessitated another invention.
The wheel was invented around 4000 B.C.E., according to archaeologists. The wheel was most likely invented independently in Mesopotamia (modern-day Iraq). Estimates for when this happened range from 5500 to 3000 B.C.E., with the majority of experts putting it closer to 4000 B.C.E. The oldest depictions of wheeled vehicles come from around 3000 B.C.E., however the wheel may have been in use for millennia before these paintings were drawn. Wheels were also utilized to make ceramics during this historical period, according to the evidence. (It's worth noting that the original potter's wheel was most likely not a wheel at all, but rather an irregularly shaped slab of flat wood with a small hollowed or pierced area near the center and put on a stand on a stake driven into the ground The potter or his assistant would have turned it with repeated tugs.) The world's oldest known wooden wheel was recently discovered in Slovenia's Ljubljana wetlands.
Transportation, warfare, and pottery manufacture were all changed by the discovery of the wheel (for which it may have been first used). It wasn't long until wheeled wagons were discovered to be capable of carrying huge loads, and quick (rotary) potters' wheels enabled early mass production of pottery. The application of nonhuman power sources was revolutionized by the use of the wheel as an energy transformer (via water wheels, windmills, and even treadmills).
