Science and Technology

Science and technology work together to change the world. Science helps us understand nature by asking questions and doing experiments. Technology uses scientific knowledge to create tools, machines, and systems that solve problems. New science leads to new technology, and new technology helps scientists make more discoveries.

How Science Leads to Technology

Many technologies started as scientific discoveries. Scientists learned about electricity, and engineers created light bulbs and computers. Scientists discovered radio waves, and engineers built radios and cell phones. Understanding germs led to vaccines and antibiotics. Science gives us the knowledge, and technology puts it to use.

How Technology Helps Science

Technology also helps science advance. Powerful microscopes let scientists see things too small for the human eye. Telescopes let them see distant galaxies. Computers help scientists process huge amounts of data. Satellites monitor Earth from space. Better tools lead to better science.

Fun Facts

• The internet was originally created to help scientists share research data quickly.
• X-ray technology was discovered by accident when a scientist noticed a glow on a screen near his equipment.
• GPS technology was developed using Einstein's theory of relativity to make it accurate.

Did You Know?

Microwave ovens were invented by accident! A scientist named Percy Spencer was working with radar equipment when he noticed the microwaves melted a chocolate bar in his pocket. He then experimented with popcorn and eggs, and the microwave oven was born!
