Periodic Table - what standards?

So one would think there are fixed criteria for organizing the periodic table. But soon after I made my version available on the web, I discovered that other tables are not so consistent in several areas. In fact, even my reference materials don't agree on those points.

1. What is the official range of the lanthanide and actinide series? In particular, does it include lanthanum/lutetium and actinium/lawrencium? It seems like it does, but some tables put one of the start/end elements in the main table.

2. Which elements are in the other/poor metals?

3. Which elements are in the semi-metal/metalloids?

4. Are there two series with other metals/non-metals, or three with poor metals, semi-metals, and non-metals?

5. Does the halogens have their own series, or are lump together with non-metals?

6. Which series does hydrogen belong to?

7. Is it lanthanide/actine or lanthanoid/actinoid?

No wonder everyone wants to have their own version of the table to match what they believe is the correct classification! I'll update my table once I have these issues sorted out.

English Chinese Periodic Table of Elements 英漢元素周期表

I love reference material, and the periodic table of elements is one of my favorite charts. I like how it presents a dense amount of information in a small space and in an organized way. I especially like how the layout of the table also convey important information about the nature of the elements.

I am currently doing some personal studying in chemistry/physics areas, using primarily a Chinese text. What I wish I had was a periodic table with the standard information (atomic number, atomic weight, symbol, name) AND with Chinese names of the elements. I couldn't find something with all those parts on the net, so I created my own version. Here it is for all to share:

I hope other bilingual science enthusiasts will find it useful too!

Colorful rice

Taiwan researchers have created new strains of rice that are colorful and nutritious. The first four colors are yellow, green, pink and purple rice. Yellow rice gets its hue from curcumin, a herb used in curries and is believed by some to be an antioxidant. Green rice comes from bitter gourd, pink comes from tomato, and purple from a mixture of vegetables. But the researchers aren't stopping there. They are hoping to create up to 14 colors so that one can have a different color rice everyday for two weeks.

New Microsoft educational products

Microsoft has announced their new education products. They include:

  • Learning Essentials for Microsoft Office: a set of add-ons to Office XP/2003 that includes toolbars, tutorials and templates for common student tasks.

  • Shared Computer Toolkit for Windows XP: software tools and documentation for locking down shared computers. A public beta of this is available at

  • Microsoft Student 2006: "a productivity resource to help middle- and high-school students complete high-quality homework assignments and projects". Features include:

    • "Graphing Calculator software to help students visualize and understand difficult math and science concepts through 2-D and 3-D graphing capabilities
    • Learning Essentials for Microsoft Office
    • Additional tools streamline Internet searches to provide trusted Encarta content

    It is interesting to note that they are not marketing this as "Encarta plus extra stuff", but rather as a student productivity suite. In fact, they only subtly say that Encarta is included as part of the product.

  • Encarta Academic Online: "a new academic-specific, online version of Microsoft's reference library, suite of homework tools and rich multimedia content. Encarta Academic Online features a new interface optimized for academic searches and gives students one-click access to Encarta reference content in seven languages for 11 countries."

Microsoft Encarta 2006 marketing

With the release date only a few weeks away, I'm surprised to find very little advanced information about the product. One interesting thing that I have noticed is that the package now contains both CD's and DVD's. This makes a lot of sense, since it is much cheaper to include the extra disks in the package than to come up with a different package that differs in just the disks.

It looks like there is some price changes too. The 2005 version sells for $100 Cnd. The 2006 version sells for $80. That sounds great -- less money for more stuff. But the marketing department is one step ahead. The new Microsoft Student 2006, which includes Encarta and more stuff, sells for $120. So does one pay less money for the old stuff which will be psychologically viewed as junk because now one can pay more money for newer stuff. Clever those marketing people.

Microsoft Encarta 2006 and a look back

The tagline on Encarta 2006 says "the complete companion to research and the internet". It is interesting to compare that to the 1994 version's tagline "the complete multimedia encyclopedia". Here is a table showing the content and media changes between the 1994, 2005, and 2006 versions.
