 Science

(PHYS 200) This course provides a thorough introduction to the principles and methods of physics for students who have good preparation in physics and mathematics. Emphasis is placed on problem solving and quantitative reasoning. This course covers Newtonian mechanics, special relativity, gravitation, thermodynamics, and waves.
This class was recorded in Fall 2006.

24  The Second Law of Thermodynamics (con't) and Entropy
The focus of the lecture is the concept of entropy. Specific examples are given to calculate the entropy change for a number of different processes. Boltzmann's microscopic formula for entropy is introduced and used to explain irreversibility.

23  The Second Law of Thermodynamics and Carnot's Engine
Why does a dropped egg that spatters on the floor not rise back to your hands even though no laws prohibit it? The answer to such irreversibility resides the Second Law of Thermodynamics which explained in this and the next lecture. The Carnot heat engine is discussed in detail to show how there is an upper limit to the efficiency of heat engines and how the concept of entropy arises from macroscopic considerations.

22  The Boltzmann Constant and First Law of Thermodynamics
This lecture continues the topic of thermodynamics, exploring in greater detail what heat is, and how it is generated and measured. The Boltzmann Constant is introduced. The microscopic meaning of temperature is explained. The First Law of Thermodynamics is presented.

21  Thermodynamics
This is the first of a series of lectures on thermodynamics. The discussion begins with understanding "temperature." Zeroth's law is introduced and explained. Concepts such as "absolute zero" and "triple point of water" are defined. Measuring temperature through a number of instruments is addressed as well as the different scales of measurement. The second half of the lecture is devoted to heat and heat transfer. Concepts such as "convection" and "conduction" are explained thoroughly.

20  Fluid Dynamics and Statics and Bernoulli's Equation
The focus of the lecture is on fluid dynamics and statics. Different properties are discussed, such as density and pressure. The Archimedes' Principle is introduced and demonstrated through a number of problems. The final topic of the lecture is Bernoulli's Equation.

19  Waves
Waves are discussed in further detail. Basic properties of the waves such as velocity, energy, intensity, and frequency are discussed through a variety of examples. The second half of the lecture deals specifically with superposition of waves. Constructive and destructive interferences are defined and discussed.

Teaching doesn't get much better than this
A true master.
Fantastic resource
Incredibly helpful for my AP Physics class. The professor doesn't just give you formulas and show you how to use them, he goes into a lot of depth showing how the formulas are derived and why they work. He is very clear but concise, may be too fast for some but that's why you can pause, rewind the video.
Amazing!!!
So so so helpful!! My uni has pod casts too but this guy is great. He doesnt just expect everyone to know what's going on. Also I love that he writes with chalk!
