How Things Work

Inventions

Any new idea or product that has been created by a person can be called an invention. Inventions change the way people live their lives—they make things safer, easier, faster, or cheaper.
Knowing your stuff
Technology is the science of how things work. The inventors of these shoes knew that a coiled spring is a source of stored energy. They used this technology to make powered shoes.
Better by design
Anyone can be an inventor. Many successful inventions came from engineers who used their knowledge of materials (such as iron) to try new things.
Modern technology
Today, the phrase “modern technology” is usually used to mean computers. But a few hundred years ago, steam power and mechanical presses were new and exciting technology.
Technology all around us
The use of science to provide new and better machines and ways of doing things is called technology. Every day, you use technology in one of its many different forms. Here are a few of them.

• Mechanical Mechanical

  ---

  Technology is the design, production, and use of machines like wind-up clocks and other appliances that do not use electrical, electronic, or computer technology.
• Chemical

  ---

  When the science of chemistry is used to turn raw materials into more useful things like plastics, cosmetics, or drugs, this is called chemical technology.
• Electrical Technology

  ---

  that deals with electrical circuits and equipment is known as electrical technology. It is commonly used in the design and construction of machines and power grids.
• Digital

  ---

  In digital technology, information is recorded using combinations of 0 and 1 to represent words and pictures. This system allows huge amounts of data to be squeezed into tiny spaces.
  Information.
• Biotechnology

  ---

  This term refers to technology that is based on biology—the study of living things. Biotechnology is commonly used in agriculture and food production. Genetic engineering is biotechnology.
• Medical

  ---

  Anything (like a tool, machine, process, or substance) that is used to diagnose, observe, treat, cure, or prevent people’s illnesses or injuries comes under the heading of medical technology.

The study, design, and use of electronic information systems is known as information technology. The term covers machines like computers (hardware) and the programs they run (software) etc.

Simple machines

It’s hard to hit a nail into wood with your hand, but much easier with a hammer. Tools such as this are called simple machines. They help people work faster and better.
