Week 5 Forum: Eigen values and Eigenvectors / Eigenvalues and Eigenvectors in Real Life

 Eigen values and Eigenvectors in Real Life

I first encountered eigen values and eigenvectors as a student in physics, but it turns out that they are widely used in biology, engineering, computer graphics, and geology, among many other applications. Not only are they widely used in these applications, but they often serve as a foundational concept for building other, more advanced concepts in these disciplines.

So this week let’s talk about how eigenvectors and eigenvalues are used outside of the classroom, whether it is on the job or in scientific research. What are some typical real world situations where you find eigenvalues and eigenvectors being used? Pick one such situation and describe it in some detail. Is this application more common in business, science, or engineering? Is it a practical application, or more useful in doing scientific research? What was the most interesting – or useful - thing you learned about how eigenvalues and eigenvectors are used?

Be sure to pick a situation to discuss that nobody else has explored in depth yet. Put the application you chose to explore in depth in the subject line heading of your initial post (for example, “Eigenvalues in quantum mechanics”).

Sometimes students will create an original math homework-type example as it applies to a particular situation, and even work out the numbers, but not do any internet research. Note, however, that the intent of this forum is to do outside research each week and find an application online that you were unfamiliar with, then describe that application in your post. So you will always have outside sources to cite.

Our textbook in section 5.6 contains a number of specific examples and homework problems to give you ideas, both in the e-book and in MyMathLab. You can also search online to find eigenvalue and eigenvector applications and examples. Some good websites to start out with are listed below (but there are many, many others online, so please don’t limit yourself to these):

Be sure to include the source(s) you use in your post.

Instructions: Your initial post should be at least 250 words. In addition, please respond to at least 2 other students. Your responses should help develop discussion around the topic/feedback that your classmate presented. Responses to students should be a minimum of 100 words each.
