## Astronomy 62

#### Introduction to Astrophysics

A general survey of modern astrophysics. The course starts with the fundamental physical concepts underlying much of astrophysics, including gravitation and orbital mechanics, and radiative processes (including blackbody radiation, line emission and rudiments of radiative transfer). We then move on to discuss the stellar structure, evolution and death, the physics of compact stars, the interstellar medium and star-formation, and the structure and evolution of the galaxies, galaxy clusters and The Universe. The course meets for three lecture periods each week. The students are evaluated based on their homework and test performace. In addition, each student makes a 15-minute presentation on the topic of his choice; these are spaced throughout the semester and are meant to compliment the material being currently discussed in lecture. This gives the students an opportunity to research at least one topic in considerably more depth than we are able to do in class. Offered jointly with Pomona and Joint Sciences. Prerequisite: Physics 51 or equivalent.

## Physics 24

#### Mechanics and Wave Motion

Classical mechanics is introduced beginning with inertial frames and the Galilean transformation, followed by momentum and momentum conservation in collisions, Newton's laws of motion, spring forces, gravitational forces, and friction. Work, kinetic energy and potential energy are defined, and energy conservation is discussed in particle motion and collisions. Rotational motion is treated, including angular momentum, torque, cross-products, and statics. Other topics include rotating frames, pseudoforces, and central-force motion. Simple harmonic and some nonlinear oscillations are discussed, followed by waves on strings, sound, and other types of waves, and wave phenomena such as standing waves, beats, two-slit interference, resonance, and the Doppler effect. Lectures are twice per week, and there are also two recitation sections per week, in groups of about 20 students, all of whom solve new problems at the board nearly every session. This next year we may experiment with introducing team projects, at least in some sections. This may be especially important for students who have already had a fairly strong background in mechanics, but who did not place out of Physics 24.

With this foundation in place, we are ready to discuss the nearly free electron model and the tight binding model, which are used to describe the valence and core electrons, respectively. By introducing the concept of effective mass the various electrical transport properties of semiconductors are described. In the last third of the period, selected topics in solid-state physics, such as two-dimensional systems, magnetism, and superconductivity, are covered.

#### The Science of Cooking

This course is designed as a “hands on” course. In the words of Thomas Dewey, “Learn by doing.” We will discuss what is going on when we prepare food and what goes on after we consume it.

Every day, without a second thought, we pop things into the microwave, toss dinner on the BBQ, heat something up on the stovetop, whip something up with our mixer or run it through our food processor. We heat stuff, we cool stuff and we freeze stuff. We use pots and pans made of cast iron, stainless steel, glass, aluminum and copper. We set temperatures and we set timers. We boil, simmer, braise, caramelize, liquefy, steep, brew and marinate. Did you ever stop to think that there is a method to the madness? Those seemingly abstract concepts of wave mechanics, electricity and magnetism, thermodynamics, statistical mechanics, solid state physics and even quantum mechanics dictate how tasty and healthy your meal ends up being. But what about nutrition and health...?

Can we bake our cake and eat it too? It’s all about conservation of energy! In this country we spend in excess of $40 billion dollars a year on dieting and another 2.6 billion on gym memberships. Is this all a scam, a hopeless quest? Consider that 68.8% of US adults are either overweight or obese (CDC). Obesity is a contributing factor is deaths due to heart disease, cancer, stroke, kidney disease and diabetes (CDC). Losing as little as 5 to 7 percent of a person’s total body weight lowers blood pressure, improves sugar levels, and lowers diabetes by nearly 60% in those with pre diabetes (CDC). The average size of a bagel in the US more than doubled between 1983 and 2003 (going from 4 inches in diameter and 140 calories to 6 inches in diameter and 350 calories (National Heart Lung and Blood Institute). At the current rate of increase, yearly obesity related healthcare costs are expected to exceed$300 billion dollars by 2018 — up from the reported \$147 billion in 2008.

Can we have it all? Can we prepare amazing meals and treats and still retain our health. Take the course and find out!
