I have this email sitting in my “attention” folder (a folder for important emails that I don’t have time to go to right away) for quite some time, yesterday I finally have some time to go to check it out.
It’s about a video series made by a team in Univ of Nottingham, UK and directed by BBC video journalist Brady Haran. They are quite cool. They are small video clips illustrating each of the 118 elements. Besides the usual fact about each element (such as atomic number), each video has interesting stories behind each element and experiments to showcase its physical and chemical properties.
If you haven’t checked out these, maybe you should. It would be helpful for an introductory chemistry course.
The videos are available at this web site:http://www.periodicvideos.com/, also available on YouTube (www.youtube.com/periodicvideos).

Database of Native Plants from UT-Austin Friday, 28 September 2007 3:19 pm
Posted by Dongmei in Internet Resources, biology, botany, databases.2 comments
The Lady Bird Johnson Wildflower Center, at the University of Texas at Austin, has a database of native plants (http://www.wildflower.org/plants/) with some really nice searching options.
You can do the basic searching by name or family (the search function suggests names as you type), there’s also a great search that allows you to search by state, light requirements, soil moisture, duration, bloom characteristics, and color. Results are presented in a table that includes the scientific and common name of the plants as well as images of the plants.
You may also want to check out the other links from the front page of the Native Plants Database, like the collection of how-to articles, the glossary of botanical terms, and the slide show of popular regional wildflowers. I’m sure that you’ll find this database is quite useful.

Installation Wiki Wednesday, 26 September 2007 5:08 pm

The Installation Wiki provides comprehensive and free guides to installing software and it’s an open wiki. The front page has a variety of categories, including open source, content management, Web development, databases, Java, PHP, Microsoft and .NET, and Networking and Telephony. Choose a category and you’ll get a list of software. I checked on some of the open source software like Moodle, it has very detailed instruction on how to install and configure the software.
