The Measure Activity on One Laptop Per Child (OLPC) is a tool on the XO, the $200 computer now in production, that allows kids to indulge in “learning by doing”.

It provides an interface for the kids to connect with the physical world and an opportunity to view and understand through a visual and statistical representation of the physical phenomena.

Using the Measure Activity on the XO, one can:

  1. Connect sensors (light, heat, magnetic field etc) and view their signal. Thus it is possible to view and study physical phenomena
  2. Input voltages and signals into the XO laptop and use it as an oscilloscope and
  3. Log data at a specified interval and store and retrieve waveforms

The complete index to this wiki article on the OLPC is:

Bio Engineering/ME C117: Structural Aspects of Biomaterials - Professor Lisa Pruitt, University of California at Berkeley.

This is an 82 minute overview of the entire course that spans 25 video segments on YouTube. If you wish to view the entire set of courses or download them, go to the YouTube site to obtain them.

This course provides an overview of medical devices, FDA regulatory issues, biocompatibility and sterilization technology. It examines biomechanical properties: isotropy/anisotropy, stiffness, bending stresses, contact stresses, multiaxial loading, plasticity, fatigue, fracture, wear, corrosion, design issues.

Also covered: Orthopedics, Dental, Cardiovascular, and Soft Tissue Reconstruction

There are more videos from UC Berkeley on YouTube, in fact they have their own section both on YouTube and Google Video as part of the unique arrangements that Google and the University have made.

The University of California at Berkeley is one of the pioneers in distribution of educational materials over the Web in the forms of both videos and podcasts. The latter are listed on and freely downloaded from Apple’s iTunes website.

Although primarily intended for students to review or supplement actual classroom experience, they are open to the public for enrichment and learning.

We just learned about this great web site,Universe Scale done by Nikon from a visit to The Smug Baldy Speaks (Thanks, Smuggie)

It uses excellent, advanced graphics to explain about distance and size is a very unique way.

SI units are used and illustrated in this presentation that can become almost hypnotic, if you focus on the calming sound track too much.

A great way to get to understand and remember the various terms used in measurement of length.

The Qualified Sampling Technician is trained in a process developed by NORMI™ known as the NORM IAQ Management Program. Here’s a YouTube vendor video describing the work.

Calculators are a necessity today in learning technical topics and a graphing calculator is even better. Falconphysics prepared a series of online videos in another of Steve Dickie’s examples of using web tools in science education.

It starts here at Falconphysics’s Library on ScreenCast.com. There are nine video lessons available in the library that can be embedded into any simple blog or similar webpage and replayed, sent to those with computers on the Web, etc, etc.

Here’s the first one.

In 2006 I wrote an article for Sensors Magazine on a step-by-step approach to the task of selecting and setting up a measurement sensor in an Industrial plant environment. It was their next to last printed edition of their magazine and also was published in the online edition at SensorsMag.com.

Since then I have written several follow-up articles for their online Industrial Automation E-Newsletter, expanding on each of the steps in a checklist than was in the original article.

The latest section was just published online in the December 11, 2007 issue of the Sensors Automation.

I think this is a rational approach, one honed by many years of experience and many years of not getting it right all the time.

Does anyone else feel the same way or have other points of view?

Appreciate any and all feedback.

Here’s more of the available resources on the Web dealing with measurement and measuring, a basic slide show explaining the SI Units of the Metric System. It’s from SlideShare.com, and there’s much more there and elsewhere on the Web.

We’ll be showing more as we find it and hoping you can share with us and our visitors any new treats that you find, too

Enjoy & Learn!
