About This Chapter
About This Chapter
In this chapter, video instructors show you historical technologies used to determine distance and time and their impact on civilization and progress. You'll be introduced to Galileo and learn about how his telescope got him in trouble with the Church. This chapter will discuss the relationship between latitude and the apparent position and motion of celestial objects, as well as relative and absolute methods for measuring astronomical distances.
You'll learn about the types of telescopes, deep-space probes, and artificial satellites. As you progress through the chapter, you'll learn about space exploration, its impact on technological advancements, and the scientific laws the govern space flight. When you finish this chapter, you should be able to:
- Understand how latitude relates to the motion and apparent position of objects in the sky
- Compare relative and absolute methods for measuring distances
- Discuss how historical and modern astronomic technologies affected the development of civilization
- Identify significant manned and unmanned space exploration events, programs, and objectives
Our video lessons are short, engaging, and easy to navigate. You can use video tags to toggle back and forth between all the important points in the video. Each video lesson also includes a transcript, so you can read along if you choose to. At the end of the lesson, take the self-assessment quiz to gauge how well you remember the material.
1. Types of Telescopes: Radio, Reflecting & Refracting Telescopes
Learn about the different types of telescopes that astronomers use: X-ray, radio, gamma ray, reflecting and refracting. Learn what the differences are between them and what different things they show us about the universe.
2. Galileo, the Telescope & the Church
This lesson explores the contributions of Galileo to modern science. It examines his early steps toward a scientific method, his work on falling bodies and, of course, his astronomical discoveries. Finally, the Church's reaction to these discoveries is explored.
