**Climate Change**
(Gidon Eshel)
This lab course explores the physical principles underlying climate and anthropogenic climate change. We will start with a survey of the most compelling lines of evidence for climate change, how they are obtained/derived and some of their limitations. We will then discuss in some depth idealized one-dimensional planetary radiative and thermal balance, first in the absence of an atmosphere, and then in the presence of a radiatively active one, with variable number of layers. In this context, it will become interesting to explore atmospheric opacity with respect to various radiative types, and what natural and anthropogenic effects affect this opacity. A related topic will be natural feedbacks, such as water vapor and could feedbacks. We will next place current (modern) observations of climate change in the broader context of past climates, emphasizing the last couple millennia, hundreds of millennia, and finally the ten million-year scale geological record. We will conclude the course with some discussion about the objective of a successful policy mitigation efforts, and their implementation obstacles. While not technical per se, participation in this course does require the ability to solve a couple of linear algebraic equations (like solving x + 4 = 2y and 2x - 3y = 6 for x and y) and to perform some very basic manipulation of data and plot the results (using, e.g., Microsoft's Excel).

**Introduction to Physics I**
(Matthew Deady / Antonios Kontos)
A calculus-based survey of physics. The first semester covers topics in mechanics, heat and thermodynamics, and wave motion. The course stresses ideas—the unifying principles and characteristic models of physics. Labs develop the critical ability to elicit understanding of the physical world. *Corequisite*: Mathematics 141.

**Mathematical Methods I**
(Matthew Deady)
This course presents mathematical methods that are useful in the physical sciences. While some proofs and demonstrations are given, the emphasis is on the applications. Topics include: complex functions, vector spaces, matrices, coordinate transformations, power series, probability and statistics, and multi-variable differentiation and integration. *Prerequisites*: Mathematics 141-142, or equivalent, and strong preparation in physics comparable to Physics 141.

**Modern Physics**
(Paul Cadden-Zimansky)
An extension of introductory physics concentrating on developments in physics that stem from the theory of relativity, quantum mechanics, and statistical mechanics. A major focus will be understanding classical and quantum waves, but there will also be overviews of particle physics, nuclear physics, optical and molecular physics, condensed matter physics, astronomy, and cosmology. *Prerequisites*: Physics 141-142 and Mathematics 141-142.

**Thermal Physics**
(Paul Cadden-Zimansky)
This course studies the thermal behavior of physical systems, employing thermodynamics, kinetic theory, and statistical mechanics. Thermodynamical topics include equations of state, energy and entropy, and the first and second laws of thermodynamics. Both classical and quantum statistical mechanics are covered, including distribution functions, partition functions, and the quantum statistics of Fermi-Dirac and Bose-Einstein systems. Applications include atoms, molecules, gases, liquids, solids, and phase transitions. *Prerequisites*: Physics 141-142, Mathematics 141-142.

**Photographic Processes**
(Simeen Sattar)
Topics covered in this course range from the chemistry of silver and non-silver photographic processes to the physics of CCD cameras. Laboratory work emphasizes the chemical transformations involved in making gum dichromate prints, cyanotypes, blueprints, salted paper prints and black-and-white silver emulsion prints. Registered students undertake to review elementary topics from high school chemistry and take an online quiz before the start of the semester to assess their understanding of these topics.
