On Aharonov-Bohm's Phase, and Faraday's Field (Video)
[more]Topic: "Introductory Contemporary Physics" (Video) ABSTRACT: What laws of physics apply to everything, and have no known exceptions? We can think of two--the principle of relativity and the uncertainty principle. Our goal has been to construct an introductory physics course with emphasis on these two laws. To do this, we begin with the principle of relativity, a law understood by Galileo, and end with the uncertainty principle after focusing on the particle-wave nature of matter.

[more]Topic: "Helping Students Connect Meaning and Mathematic" (Video) ABSTRACT: Mathematics is the language of physics, yet mathematics may sometimes seem simply as a way to calculate numbers to our students. This talk will focus on several ways that students do use mathematics to do physics (some productive, others not as much), and how we can promote student use of the productive ways of using mathematics.
[more]Topic: "Star Formation Feedback: Do Stars Practice Birth Control?" (Video) ABSTRACT: The link between turbulence and feedback in star formatting environments and protostellar jets remains controversial. Star forming clouds are highly inefficient with only 10% to 30% of cloud becoming stars. In this talk I will present a general overview of how stars may control their own formation efficiency by feeding energy back into the cloud which created them.
