VII. Science and Technology
• Science and Technology are important parts of culture. • Science – the active process of acquiring knowledge of the natural world. • Technology is the way in which people use tools and machines.
A. Technology and Progress • Early humans made gradual advances in technology. • About 3 million years ago, people first learned how to make tools and weapons out of stone • later on, they discovered how to control fire
• Technological advances changed cultures • early humans were hunters and gatherers who traveled from place to find food. • Later, people discovered how to grow crops.
• They also tamed wild animals for farming and also used them for food • Overtime, people began to rely on agricultural and domesticated animals for the majority of their food.
• Agriculture provided a steady and reliable food source • This allowed people to settle in one area permanently. • These settlements eventually turned into cities
• As cities developed, people began to create government to watch over the people • People also developed systems of writing that helped people write laws
• All of these advances led to the development of the first civilizations about 5, 000 years ago • Civilization – a society with a complex culture
• As civilization became more advanced, they developed new technology to make their lives easier • For example, many cultures created irrigation canals to provide their crops with much need water • irrigation – supply of water to crops
• Cultures that lacked these new technologies developed much more slowly • Eventually, advanced technology would spread throughout the entire world.
B. Modern Technology • Beginning around 1800, people developed new technologies that used power-driven machinery • This was called the Industrial Revolution • It led to the growth of cities, science, and many new businesses
• Eventually people developed technologies such as automobiles, airplanes, computers, and space travel
• All of these advances in technology have led to a rise in people’s standard of living • Standard of Living – the level of comfort enjoyed by a person or a society. • Modern technology also helps to connect people, products and ideas.
