Joined the Middlebury College faculty in 1969

I am a professor in the Department of Physics at Middlebury College, where I have been a member of the faculty since 1969.  My current research centers around supernovae, supernova remnants, and the interstellar medium.  Simply put, I am interested in how stars blow up, what is left after they do, and how they enrich the cosmos in heavy elements like oxygen, carbon, silicon, iron, etc.—the elements that play a crucial role in the development of planets and life on them.

I have taught most of the courses in the Physics Curriculum at Middlebury at one time or another, but I am now on Associate Status, teaching only in the Fall Term, when I teach two somewhat different versions of our introductory astronomy course.

A more-or-less complete CV can be found here.

Research

My research is based on observations carried out across the electromagnetic spectrum, primarily optical (using facilities such as Kitt Peak National Observatory, Cerro Tololo Inter-American Observatory, Gemini and the Hubble Space Telescope), and X-rays (primarily using the Chandra X-ray Observatory).

I am particularly interested in young supernova remnants—ones where we can still find clues about the nature of supernova explosions, the stars that led to them, and the debris that results.

Teaching

Every Fall Term, I teach two versions of introductory astronomy:

Physics 0155, "Introduction to the Universe"  is open to all students, regardless of background.  For more details ab

Physics 0165, "Physics in the Universe" is a more analytical version, and is open to students who have taken Phys0109 (Newtonian Physics) or another college-level physics course (e.g., AP physics), and a semester of calculus (e.g., Math0112).

For more information about the Fall 2011 versions of these courses, see:  PHYS0155, Fall 2011 or  PHYS0165, Fall 2011

 

Courses

Courses offered in the past four years.
indicates offered in the current term
indicates offered in the upcoming term[s]

PHYS 0111 - Thermo, Fluids, Waves & Optics      

Thermodynamics, Fluids, Wave Motion, and Optics
This lecture and laboratory course covers concepts from classical physics that are not included in PHYS 0109 and PHYS 0110, and that serve as a bridge between those two courses. Topics include thermal properties of matter, thermodynamics, fluid mechanics, wave motion, sound, and geometrical and physical optics. This course is strongly recommended for all students otherwise required to take PHYS 0109 and PHYS 0110 as part of a major or a premedical program, and is required for physics majors. (PHYS 0109, MATH 0121, or equivalent)

PHYS 0155 / PHYS 0165 - Introduction to the Universe      

An Introduction to the Universe
Our universe comprises billions of galaxies in a rapidly expanding fabric. How did it begin? Will it expand forever, or how may it end? How do the stars that compose the galaxies evolve from their births in clouds of gas, through the tranquility of middle age, to their often violent deaths? How can scientists even hope to answer such cosmic questions from our vantage point on a small planet, orbiting a very ordinary star? Are there other planets, orbiting other stars, where intelligent beings may be pondering similar issues? This introductory astronomy course, designed for nonscience majors, will explore these and other questions. Students will also become familiar with the night sky, both as part of our natural environment and as a scientific resource, through independent observations and sessions at the College Observatory. The approach requires no college-level mathematics, but students should expect to do quantitative calculations using scientific notation and occasionally to use elementary high-school algebra. (Students may not receive credit for both PHYS 0155 and PHYS 0165.) 3 hrs. lect./ hrs. lab./disc.
