Technology started when early man tried to improvise tools from locally available materials such as stones, animal bones, wood and iron. While doing this, he stumbled upon numerous ideas such as the ability to generate fire by rubbing a stick at high speed.Continue Reading
Although man’s ancestors had limited ways to advance their newly found ideas, their narrow expertise made life easier. For example, they were able to cook food to make it softer and easier to eat. Gains in the Stone Age led to the development of agricultural tools and techniques. Agriculture became a new source of livelihood and eased the pressure from hunting. From then on, modern civilization started to advance.
Many decades later, the era of information technology came about. The Soviet Union launched the first satellite, called the Sputnik, at the height of the Cold War in 1957. America was stunned, and to counter the launch, it created the Advanced Research Projects Agency to develop computer science. Although computers at that time were huge devices that filled entire rooms, they could process some information. Later, the agency succeeded in connecting four computers running independently. That simple connection gave rise to the Internet, which is a pivot point of developing other technologies.Learn more about Inventions
Native Americans used a variety of materials for arrowheads, including, rocks, stones, and other organic material, such as wood, bones and horns. The earliest arrowheads were made of hard stones such as flint and obsidian that were shaped and sharpened through processes known as flintknapping and pressure flaking. These processes involved striking the flint with hammer-like objects to break off smaller flakes, which were then shaped into points and notched for attachment to arrows.Full Answer >
Examples of organic materials include wood, paper, textiles and animal parts. Organic materials are any type of materials that are found in nature or are made out of items that are found in nature. Organic materials are composed solely of organic compounds. These compounds contain the element carbon, which is widely found in nature in plants and animals. Organic materials naturally deteriorate over time, according to Preservation 101.Full Answer >
Scientists believe iron was first discovered in Egypt. Iron has been found in many ruins across the ages, ranging from as far apart as Mesopotamia and the western Roman Empire, but the oldest iron relics were found in Egypt and date from around the year 5000 BC.Full Answer >
Technology has helped streamline doctor-doctor and doctor-patient communication; maintain medical health records for efficient health care provision; and help patients to keep healthy through apps and equipment such as menu trackers, food monitors and calorie counters, according to Ellen Lee for Forbes. Technology has also facilitated medical research, resulting in medical breakthroughs in health care.Full Answer >
