This is a short podcast where we introduce the concept of covariance, one of the quantities that is part of the law of propagation of uncertainty. I am considering doing another podcast in a series, but that depends on feedback.

Also discussed are the new feature on the "My Programs" page where progress with programs can be monitored, and a certificate of completion requested; as well as the ability to leave video messages and questions that can be used on the podcast.

This is a short podcast, about 12 minutes. I am thinking about limiting future podcasts to 20 minutes so that they can be posted on YouTube. As always, I am seeking feedback from you on what you would like to see on the podcast or on the website.
