optical instruments

"An illustrated picture book of early scientists Antonie van Leeuwenhoek and Galileo Galilei, who used similar observation tools but saw the world very differently, their discoveries leading to innovations in both microscopes and telescopes." --Provided by publisher.

"Explains the principles of light, lenses, and other key science ideas behind the technology of telescopes, binoculars, and microscopes. The book discusses the history of the inventions, their uses, and how to select one for purchase"--Provided by publisher.

Text and photographs show young readers how scientists use microscopes and hand lenses to make up-close observations.

Before magnifying glasses, how did people make objects look larger? The ancient Romans filled glass bowls with water. Then microscopes and telescopes came along. But optical innovation didn't stop there. Learn how many lightbulb designs Thomas Edison tested, how spies used microfilm to carry secret messages, how satellites let us look at Earth from space, and more! Follow the trail of inventions and devices that have enabled us to see everything from distant stars to tiny cells.

"Most of us rely on our eyes to see and understand the world. Yet, human eyes are far from perfect. Over the years, we have looked for ways to improve our imperfect sight. Let's meet the innovations that have changed how we see the world. Glasses, goggles, prisms--and so much more. Dive into the world of optics, where light bends to help us see the sights!"--Provided by publisher.

Explores the properties of light and color by means of experiments and analysis of various optical instruments including periscopes, and telescopes.

Photographs, illustrations, and simple text describes the concepts of light and dark, how light can travel at different speeds, how a lens works, and how special types of light can be used.

Highlights the work and findings of several well-known and influential scientists who have expanded our knowledge and understanding of light and sound.
