Physics 2000 Einstein's Legacy

This section of Physics 2000 focuses on modern technological wonders. Some of them will be rare and expensive devices, but others will be common tools and appliances that you might even have around the house. What all of them have in common is a reliance upon basic physics that were only understood in this century. Your guide to the devices in Physics 2000 will be Professor Lee.

Together we're going to learn how some of the physics pioneered by Einstein and other scientists is used around us today in everyday life. These technological marvels are truly Einstein's "Legacy" to us.

Here we'll learn about how X-Ray machines work, including how x-rays are produced and why they work the way they do.

CAT Scans

We'll explore three-dimensional "CAT Scan" imaging, which uses x-rays to obtain pictures from organs and bones inside the human body.

Microwave Ovens

Microwave ovens are surely the most misunderstood devices in the home. Find out how they really work and dispel a lot of mythology about their dangers.


Space weapons of the future or useful tool? Lasers have been around for decades now, but who understands what they really are?

TV Screens

Learn how TV screens produce the images that draw our attention every day. Discover the role of electron beams making those images.

Laptop (LCD) Screens

Learn how laptop (or LCD) screens produce the images, understand how liquid crystals control the light.
