An interactive course on electronics, starting at the absolute beginning.

This course is mostly intended for hobbyists who want to start building their own circuits, but the content will be useful to anyone who wants to learn more about how electronics work.

Students are not expected to have any prior knowledge of electricity or electronics.

Metals and Materials Science

This course covers a wide range of material science subjects. If followed chronologically, the student will first learn about every metallic element on the periodic table, including their properties and applications. The course goes on to examine other material science topics such as electron microscopy and even magnetism. A background including high school AP chemistry, first year collegiate chemistry, or a short background on atomic structure will be helpful.

The Art and Science of Making Great Beer

Are you interested in making your own high quality beer at home? Are you a already an all-grain homebrewer? This course is designed for beginning and advanced homebrewers alike.

I have been homebrewing for years and have a degree in microbiology. I am also a real-life teacher (for now, actually looking to move into the pro-brewing industry).

This class will feature homebrewing demo videos, lectures/presentations about the science of brewing, and interviews and discussion with other brewers (home and pro) about various relevant topics.

General Chemistry

This course will be covering topics typical of a college freshman general chemistry course.

All topics in the scope of general chemistry will be covered including basic chemical bonds and molecular structure, thermodynamics, equilibria, kinetics and everything in between (full list found in syllabus).

My teaching philosophy revolves around rigor and depth. I enjoy challenging my students to think. As a result, assuming you utilize all the material I provide, you will have a very intimate understanding of the course material by the conclusion of the course.

Nuclear and Radiochemistry

The purpose of this course is to introduce the theories and phenomena of nuclear science. The course will be structured so that enough depth of understanding is obtained to apply nuclear science to your eld of interest. The fundamental ideas that we will focus on are:

  1. Phenomena of nuclear properties and structure

  2. Kinetics and theory of radioactive decay

  3. Theory of nuclear reactions

  4. Interactions of radiation with matter (including biological systems)

Nuclear Reactor Physics : Neutronics

Neutron physics is the study of the travel of neutrons through matter and the resulting reactions, most notably power generation via the fission of nuclei of heavy atoms, i.e. nuclear reactor cores.

Basic Biochemistry

Humans adapt to technology very easily. We can drive cars without knowing what’s under the hood. We can use computers and smartphones much the same way. Among all the different pieces of technology used by us, an obvious but often overlooked example is that of our own body. Not many of us think about the Biochemistry that is always taking place in our body.

This course will link everyday experiences with topics that lie at the core of Biochemistry.

By studying how our body transforms sugars, fats, and the proteins, we will follow the transformations of the food stuffs in our breakfasts, lunches and dinners. We will read lectures from Nobel Laureates, we will peer into the active sites of enzymes, and we see how modern medicine deals with things going wrong.


Introduction to Nuclear Magnetic Resonance (NMR) Spectroscopy

Notation and Conventions


Hey, baby. What do you say you and I go somewhere and kick it 90 degrees? You know, get a little simple harmonic motion going on. Aw yeah. We're gonna pulse, we're gonna gyrate, we're gonna resonate. We're gonna savor the moment. The magnetic moment, that is. Let's do some NMR.



>>A: You should talk about answers with eachother. If I post something, you should talk about it with others. I have posted threads for quizzes so far, but if I don't in the future, you should create one if you understand the quiz. The only course content with a somewhat official "hand in" are problem sets which for your own benefit only you have the option of emailing to me at to have hand graded and commented on. Anything else is open for whatever. The quizzes and discussions of instructional videos/materials are free form. The quizzes and problems are meant to be instructional, and a large part of the instruction in this course will be up to you to ask and probe me and others about. You'll notice the first two videos are like 2:00 each. That trend will continue. So most of this course will count on talking to one another.

Nuclear Magnetic Resonance is a physical phenomenon that can be exploited for a number of practical purposes in medical imaging (MRI's), materials science, and industry in general (for example, oil well logging), and is a topic of ever increasing interest. The inherently quantum effects involved in the phenomenon are rich in complexity making NMR spec. instrumentation a broad and interesting field in its own right.

This course would be most suitable for a natural science undergraduate, graduate student, or technical professional who would like to understand nuclear resonance. The course will quickly introduce new concepts (especially in electronics) and be relentlessly cumulative in nature, so a course in electrodynamics would be useful. However as the lectures are highly pictorial and both qualitative as well as quantitative, anyone who is curious could learn something.

The course will cover:

1) The concept of NMR and its relation to other phenomena

2) Theory of NMR

3) Instrumentation and technique

It would be wonderful to be able to follow the above ordering of topics, but I personally feel, as others have mentioned (e.g. Cowan) that NMR is best understood through explanations which often involve a mix of all three at once.

Principles of Geology

This course covers a wide range of introductory geology topics. Once completed the course will have prepared the student with a basic compendium of knowledge concerning earth processes, physical structures, and morphology and expression of rocks at the surface of the Earth. Work in this class will consist of the study of solid earth processes, rocks and minerals, and will include several virtual field trips to reinforce the concepts explored in the class. Additionally, I will post several self tests to allow you to check your understanding of the concepts you have learned.

Healthy Eating

Diabetic Diet Plan: A Healthy Eating Plan for Diabetics It is very important that we take those foods which balance our body glucose and provide energy as per our body requirements. Diabetics need to eat those food items which have low glycemic index (GI), rich in fiber, vitamins and minerals, etc.

Basic Newtonian Mechanics.

An introduction to Newtonian Mechanics, focusing on linear mechanics. Basic calculus will be covered first, then we will cover Newton's Laws of motion, forces, momentum and coefficients of restitution.

Introduction to Meteorology

Classes will start Jan 2015. This course is an introduction to our atmosphere, weather, and how it affects us. Easy to follow lectures with real-life examples, you can easily become a weather wiz!

Introduction to Clinical Neurology

Clinical neurology is a branch of medical science that deals with the diagnosis and treatment of neurological disorders in patients. In this course we will be focusing on anatomy, cellular biology and pathology as it relates to the human brain.

Vet Science

This class will be teaching the basics of Veterinary Science. In this course you will learn about diseases, suture wounds on animals, and much more.


chemisty deals with the composition and properties of matter and it also comprises of observation, hypothesis theory and conclusion.chemistry is divided into different branches which include ①physical chemistry②organicchemistry.
