Kinetic Energy and Work
Animated billiard balls help demonstrate kinetic energy - the energy of motion. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Other key vocabulary words addresses in this video include: work, force, mass, acceleration, newtons, joules, innertia, gravity, movement, speed, distance, and transfer of energy. (04:49)
Family Readiness Groups and You
Juanita McKeown, FRG and FRSA program manager, Mobilization and Deployment, presents a session on family readiness groups and family readiness support assistants as part of the Army War College Military Family Programs readiness series.

Mammoth Cave National Park DVD Highlights
This video provides a 2-minute highlight of the Mammoth Cave National Park DVD. Available on location in Mammoth Cave National Park and from www.finleyholiday.com. Enter into the beautiful world of Mammoth Cave National Park and learn its story. From the enchantment of Frozen Niagara to amazing subterranean waterways, you will explore the best of the park.
D-Day Invasion of Europe (2:01)
On June 6, 1944, Allied troops storm the beaches of Normandy in the largest amphibious assault in history. This is a good video that explains what happens on this day and has excellent graphics and clear explanations. A map of the area would be of benefit.
Migrants stranded on Italian island
Strong winds and rough seas prevent ships deployed by the Italian government from docking at the island of Lampedusa, halting efforts to clear the island of thousands of North African migrants.
Protests erupt across Syria
Protesters took to the streets in several Syrian cities on Friday - in a direct challenge to the rule of President Bashar al-Assad. Jon Decker reports.
All about Electrochemistry
Site contains introductory material in basic electrochemistry. Topics include galvanic cells, electrodes, cell potentials and thermodynamics, Nernst, batteries and fuel cells.
Animation of pulse dampner in HPLC
This animation site deals specifically with pulse dampners is LC and could help in a general lecture about LC pumps. The animations are short (one to two minutes) and can easily be shown in class as part of a lecture. They are extremely helpful in illustrating key components and concepts of chromatographic systems. Users are encouraged to explore the site and the other brief animations as well. Separate links to other simulations by the same company (TRSL) are also listed on ASDL.
Atomic Emission Spectroscopy
A learning module that explains the instrumental systems and interactions involved in atomic emission for elemental analysis. Completion of the module will leave the learner with knowledge of optics, plasma sources, and trade-offs in choosing the right instrument for a given analytical task.
RSC.org: UV/Vis Spectroscopy
This video distributed on YouTube is on the basic principles of UV/Vis. Provides a good primer (~5 min), and the top-off look of the instrument is useful in explaining components. A double beam instrument is described.
RSC.org: Gas Chromatography
This video, distributed on YouTube by the Royal Society of Chemistry is on the basic principles of GC. This video is a short primer (~5 min) which introduces the technique and instrumentation.
There are many assumptions that are made in the presentation of this material, due to the fact the video is meant to be a basic introduction. Examples of such assumptions include the statement that volatility solely controls the elution order of volatile compounds on a GC column and that concentration
Atomic Force Microscopy
A video lecture on Atomic Force Microscopy (AFM) by Prof. Arvind Raman of Purdue University that discusses the historical development, instrumentation and operational principles of various AFM modes. The lecture is accompanied by power point slides with clear illustrative graphics. Basics are provided in the application examples with advantages and limitation discussed. Useful site to those interested in learning AFM.
Fluorescence Correlation Spectroscopy
Previously published as part of an online biophysics textbook, the article has rich and fairly complete scientific content.
NMR of Paramagnetic Proteins
This site presents an overview of techniques used for structural elucidation of paramagnetic metalloproteins. The content is directed to the more advanced NMR user and would be suitable for an upper division or graduate level NMR class.
A Pictorial Representation of Product Operator Formalism: Non-Classical Vector Diagrams for Multidim
This site presents a pictorial description of the product operator formalism using a non-classical vector approach. This approach allows for the representation of any arbitrary multidimensional or heteronuclear NMR experiment. A description of a complete set of 16 vector representations for weakly-coupled two-spin (I=1/2) systems is given followed by an extension of this set to three-spin systems. Finally the concepts of coherence transfer, multiple quantum spectroscopy and phase cycling are ill
Busy Researchers Guide to Chromatography
The Busy Researchers\' Guide to Chromatography is a pdf book focused on the vendor\'s (PerSeptive Biosystems) products (perfusion-based chromatography) with an eye toward their application in bioanalysis. The book is a nicely written and practical introduction to chromatography suitable for use with undergraduates. The last several chapters define the basics of liquid chromatographic separations and the first few give a nice overview of how one does a method development for a specific biologic
