Extra Credit 2

Modern quantum mechanics was originally put into two quite different, but nevertheless equivalent, mathematical forms.  In 1925 Werner Heisenberg developed a formulation based on matrix algebra.  Just about one year later, in 1926, Erwin Schroedinger discovered the wave equation, which is now called the Schroedinger equation.  This equation became the cornerstone of the wave function formulation. Today this formulation represents the traditional approach to teaching introductory quantum mechanics.

In 1941 Richard Feynman developed a formulation of quantum mechanics which is mathematically equivalent with the previous ones. The formulation is called the amplitude formulation and it is also known as “the sum-over all paths theory” or “the many paths approach”.

For this extra credit assignment read Chapter 2 of "QED: The Strange Theory of Light and Matter" by Richard P. Feynman (Princeton University Press, 1985).  You can listen to Richard Feynman delivering the actual lectures at http://www.vega.org.uk/video/subseries/8.
You will find a link to chapter 2 under course materials on Blackboard.

As you read, answer the following questions.

Use Microsoft Word to prepare a report that contains your answers to these questions.
