- 1. Some inventions are used mainly in science, while others have changed people’s daily lives. Tools like the telescope and microscope help us explore and understand the world. Others, such as the thermometer and Band-Aid, are used more often and support health and safety in everyday life. The telescope, which was invented in the early 1600s, is a tool used for looking at stars and planets. It was first improved by Galileo Galilei, who was an Italian scientist. His telescope helped people observe the sky in greater detail and discover how planets move. The microscope, which lets us see things that are too small to view with the eye, is another invention that changed science. It is used for studying cells, bacteria, and tiny organisms. Scientists, who work in medicine and biology, rely on it to do important research. The first compound microscope, which was created in the 1590s, opened the door to microbiology. The thermometer, which measures temperature, was invented by Daniel Fahrenheit in 1714. It is used in homes, hospitals, and weather stations. For example, doctors use it to check for fever, and meteorologists use it to report the weather. The Band-Aid, which was invented in 1920, was designed by Earle Dickson, who worked for a medical supply company. His wife often had small cuts from cooking, so he created a simple solution. Today, Band-Aids are found almost everywhere. These four inventions, which serve different purposes, continue to improve both science and everyday life. Whether in a lab or in a kitchen, their impact is lasting and meaningful. What is the main purpose of the telescope?
