Note - This is an Archived course This is a past/archived course. At this time, you can only explore this course in a self-paced fashion. Certain features of this course may not be active, but many people enjoy watching the videos and working with the materials. Make sure to check for reruns of this course. PHYS201x follows introductory physics courses with a more detailed treatment of oscillators, waves on strings, and electromagnetic waves. In addition to deriving and solving the wave equation, mathematical methods will be introduced on making approximations, describing oscillations with complex numbers, and synthesizing functions with Fourier series. Optical reflection and refraction will be derived, as well as the lens equation and elements of geometrical optics. Optical interference, diffraction, and polarization will be covered in detail, including the role of diffraction in image formation. PHYS201x will have weekly video lectures that explain the material through detailed derivations and demonstrations. There will be weekly homework, a discussion forum, and two exams. Eight weeks of content will be presented, and one week devoted to each self-paced exam.

This is the second of a two-part course. In the first part we learned about innate immunity and B cell function. The second part covers T cell function and coordination of the immune response. When you're sick, you may wonder, "Why me?" But the real question should be, "Why am I not sick all the time?" You might even ask, "Why does my body respond with a fever, and is it really a good idea to lower it?" This course explores immunology, how the body defends itself from constant assault by parasites and pathogens. This course will present the fundamentals of both innate and adaptive immunity, emphasizing functional interactions among cells and organs. We will cover signaling, pathogen recognition and the division of labor among myeloid, lymphoid and supporting cells. The subject matter will also supply health professionals and biomedical researchers with the basic vocabulary and concepts necessary to understand both clinical press releases and primary literature. The course materials also provide support to other immunology instructors by presenting difficult concepts in creative ways using analogies and models.

Preparing for the AP Biology exam requires a deep understanding of many different topics in biology as well as an understanding of the AP exam and the types of questions it asks. This course is Part 2 of our XSeries: Preparing for the AP* Biology Exam and it is designed to prepare you for the AP Biology exam. In Part 2, you will explore how information is passed from one generation to the next. You will look at the molecular level of genetics as well as the bigger picture. Learn how DNA holds the instructions to life. As you work through this course, you will find lecture videos taught by expert AP Biology teachers, practice multiple choice questions and free response questions that are similar to what you will encounter on the AP exam and tutorial videos that show you step-by-step how to solve problems. By the end of the course, you should be ready to take on the AP exam! Additional Courses in this XSeries: Preparing for the AP* Biology Exam – Part 1: The Cell Preparing for the AP* Biology Exam – Part 3: Evolution and Diversity Preparing for the AP* Biology Exam – Part 4: Ecology Preparing for the AP* Biology Exam – Part 5: Review and Exam Preparation Learn more about our High School and AP* Exam Preparation Courses AP Biology is a registered trademark of the College Board, which was not involved in the production of, and does not endorse, this product.

PHYS 102.1x serves as an introduction to electricity and magnetism, following the standard second semester college physics sequence. Part 1 begins with electric charge in matter, the forces between charges, the electric field, Gauss's Law, and the electric potential. Electric current and resistance are introduced, and then DC circuits are described, including time-dependent behavior with resistors and capacitors. PHYS 102.1x consists of 5 weekly learning sequences, each with ~1.5 hours of video lectures, conceptual lecture problems, and online homework questions. The course concludes with an online exam during the 6th week.
