Chapter 41: Elementary Particles and Cosmology

Study Plan

Trails of small bubbles reveal the passage of high-energy particles in a bubble chamber filled with liquid hydrogen. A high-energy proton entered the chamber and struck a proton in a hydrogen nucleus, and the collision produced a spray of several kinds of new particles.

While learning about elementary particles in this chapter, we will consider such questions as:

  • How do charged particles make trails of bubbles in a bubble chamber? (Section 41.1, page 1399)
  • The several tracks emerging from the aforementioned collision reveal the creation of new particles in the collision. What reaction created these particles? (Section 41.1, page 1400)
  • How can we calculate the momentum of a particle from the radius of curvature of the track? (Example 2, page 1401)
  • Besides energy and momentum, what quantities are conserved in a reaction that creates particles? (Section 41.3, page 1406)

Organize

  1. Prepare for lecture by reading the assigned sections from Chapter 41 in your textbook or ebook. This will provide an organizing framework for concepts introduced in lecture, and help you take better notes.
  2. Take the checkup quiz and work the Checkup questions in your textbook to assess your understanding of basic concepts. Take note of any topics you need to review further.
  3. Review the Examples from your textbook. These progress from simple to complex, and provide concrete illustrations of the concepts discussed.

Learn

  1. Re-read Chapter 41 and review your lecture notes.
  2. Use the FlashCards to test your memory for new key terms and equations.
  3. Work the end of chapter Problems and Review Problems assigned by your instructor. If your instructor has assigned SmartWork online homework, login from the right navigation pane.
