Lesson 3 - Optical Camouflage

The concept of fiber optics leads naturally to attempts to bend light in order to achieve certain effects. One of these would be a form of camouflage. Octopi can change their skin color and texture to blend with their environment. Some scientists are working on ways to bend waves around objects in order to form an even more advanced form of stealth technology.

  5. What does Lois do at the end?

Analysis

  1. Which of the real world attempts at "invisibility" is most like Lois Doberman's? Why?
  2. What is the difference between the two real world attemps at "invisibility" you read about?
  3. Which, if perfected, will create the best technology, do you think? Why do you think so?
  4. The "nano-soup" (from the previous lesson) and the "optical cloaking" design both share a "failing." What is it?
  5. In the story, Jerry says that advances in science come from "cross-fertilization, from recognizing relationships between fields that at first sight have little to do with each other." Do you agree? Why or why not?
