Introduction to Databases Video Lectures by Stanford Engineering 
Really excellent introduction to databases, taught entirely through video lectures. This is a complete course and includes quizzes, homework, and assignments. I'm working my way through the classes one-by-one and really like how it all comes together. The pace is fast and there's not a lot of fluff...
Electricity and Magnetism Flash Animations
Several physics animations, including the following... Coulomb's LawA simulation of an experiment to determine the dependence of the electrostatic force on distance. Comparing a DC circuit to the flow of water.A simple DC circuit has a DC voltage source lighting a light bulb. Also shown is a...
Cardiac Dysrhythmia Heartbeat Dances
Great and creative video illustrating cardiac dysrhythmias using a few classic pop songs and some talented folks!
Why's (Poignant) Guide to Ruby
A very strange, funny, and helpful online book about learning Ruby. It took several pages (and an explanation from a friend) before I realized that this is exactly what it appears: a strange, funny, and helpful book that does a great job of teaching you Ruby. The comics (yes, comics) are funny and...
Getting Started with Ruby on Rails [rubyonrails.org]
I was recommended to this page by a friend who was also trying to learn Ruby on Rails. This is a great first exercise for those looking to get their hands dirty and jump right in. It talks a bit about what Rails, what MVC is all about, and then drops you right into the exercise. The one problem...
HPLC videos and instructions by Sigma-Aldrich
A little product-centric but a good introduction to HPLC techniques and equipment HPLC Column FundamentalsIntroduction to how solutes can interact with columns containing porous particles and stationary phases to result in separation. I'm listing the most helpful ones below Nick the Hero:...
X-Ray Diffraction lecture
This lecture covers electron distribution as seen by light diffraction (X-ray diffraction). The roles of molecular pattern and crystal lattice repetition are illustrated by shining laser light through diffraction masks to generate patterns reminiscent of those encountered in x-ray studies of...
Earnshaw's Theorem and Double Minima lecture
This lecture covers the "double-well potential of the ozone molecule," "stable arrangements of charged particles" as prescribed by Earnshaw's Theorem, and the all-to-familiar "plum-pudding" atom. Also talks about Coulomb's law. This is part of the Open Yale courses series.
Force Laws, Lewis Structures, Resonance lecture
This lecture covers the basics of chemical bonding and molecular structure. After discussing Lewis-dot notation and formal charge, Professor McBride shows that in some "single-minimum" cases the Lewis formalism is inadequate and salvaging it required introducing the confusing concept of "resonance...
First Organic Chemistry Lecture at Yale
A bit of an introduction to chemistry in general and how we get to the important conclusions that add to our body of knowledge. The title is "how do we know," an important question, indeed! He illustrates the fruitfulness of experiment and logic using the rise of science in the seventeenth century...
Classical Mechanics Animations
Displacement and Distance A simple animation showing the difference between the distance and the displacement. Requires Flash 5; file size is 5k. View Constant Acceleration 1-dimensional kinematics of a body undergoing constant acceleration. Includes visually integrating the acceleration and...
Complete Organic Chemistry textbook resources
This is an on-line learning component to a Carey organic chemistry textbook. Truly covers every topic out of a good O-chem textbook. Definitely worth a look if you need parts of this course explained in a different way.
Organic Chemistry IUPAC Nomenclature
Complete explanation of IUPAC organic nomenclature for all organic molecules. Also includes practice drills, interactive animations, and a simplified high school version.
Organic Chemistry Exams
HUGE store of PDF organic chemistry exams! There are midterms and finals for the first and second semester of upper division organic chemistry. Awesome resource, with I had this when I was in these classes...
Organic Chemistry Concepts
Fantastic group of organic chemistry concepts online. There are images, text explanations, several interactive molecule animations, and so much more. Concepts explained: Concept Map Periodic Table Nomenclature Summary / Group Priority Intermolecular forces Thermodynamics and Stability Table of...
Organic Chemistry Sample Problems
All of these problems are in PDF so they're easy to print out, try out, and share. List of problem sets: Chem 351 Wk 4 [PDF] Chem 351 Wk 6 [PDF] Chem 351 Wk 7 [PDF] Chem 351 Wk 9 [PDF] (solving spectroscopy problems, worked example) Chem 351 Wk 10 [PDF] Chem 351 Wk 11 [PDF] Chem 351 Wk 12 [PDF]...
Organic Chemistry Podcasts
Great little resource for anyone taking upper division organic chemistry classes. Listen to them while running/biking or just as another method to learn the material. Covers bonding, hybridization, resonance, acidity, alkanes, isomers, conformational analysis, mass spec, NMR, and reactions. Clearly...
Beginner Object-Oriented Programming in PHP
I'm sure there will be plenty of people that disagree but I found object-oriented programming one of the hardest concepts to understand when I get started writing code. I could never come up with a reason to use it so I kind of avoided I. The problem, of course, is that there was no reason to use...
Complete PHP Tutorial from W3 Schools
W3 Schools has definitely helped me through some tough times. This is a good place to start and not a bad reference if you need to brush up on a few key techniques. Is this the best place to learn PHP? I'm not so sure. The lessons are good but not as exhaustive as I'd like. PHP is a very powerful...
Organic Laboratory Experiments
First year organic chemistry preparations, including: Preparation of cyclohexene from cyclohexanol Preparation of the benzoate of phenol Preparation of 4-acetoxy benzoic acid Preparation of adipic acid from cyclohexene Preparation of tertiary butyl chloride Preparation of cyclohexanone from...
