Google AuthorRank into its Search Ranking Algorithm

0 comments
Google dominates the search engine market, so whatever it does has an influence on which websites are more visible to potential visitors. PageRank was a system based on variables that ranked a site based on keywords and key-phrases, which and how many other sites link or refer a given website, how many links a website has, and many other factors. Overall, web pages are ranked by hundreds if not thousands of variables. In an attempt to further improve search engine results, Google introduced a system that takes into account any web content author(s).

High-quality authors and content creators can boost the profile of their work and their site with a boost of recognition from new Google's search engine site-ranking system. Content authors are graded on their reputation, credibility and quality of their work. AuthorRank is the name of this new ranking factor, and it's gotten a lot of attention in the media lately.

Features

AuthorRank has several interesting features, such as time-on-site and a system of variables relating to an author's content that basically adds up to a positive-mention count. Time-on-site tracks how long a user stays on a website that appears in Google search results. There is a cutoff time, unspecified at this point, beyond which a site raises its profile on Google's ranking system. The rationale is that if visitors stay on the site longer, they are more likely to be interested and engaged with the site's content. This implies a higher-quality website deserving of better placement in search results.

Another important feature of Google's search ranking system is measures of positive mention, reference by other content and reach of a given author's content. This is a measure of popularity, important to a site's overall ranking. Lastly, AuthorRank-influenced results may look distinct, depending on other information an author provides to Google. Search results influenced by AuthorRank may include author's name and picture in a small tab next to the website link.

Using AuthorRank

If content does not have a reputable author, it may pay to ask a reputable author create some content for your site. Their credibility will likely boost your site reputation. Search engine rank is also driven by social signals such as Facebook "likes," tweets, shares and other indication of popularity, credibility, quality or approval.

Additionally, it is a good idea to generate website content and features to entice a visitor to stay on the site. The longer they stay and browse your site, the better your bounce rate and page views. The logic of this ranking is to get a rough measure of visitors' interest. Two sites may have an equal number of visiting clicks, but if one site has visitors leaving after an average of 15 seconds and the other one has them staying for over 5 minutes, the second site will be seen as more favorable to Google.

Possible Flaws

What is an objective measure of credibility and productivity? For example, how does one rank:
  • a physics professor who wrote a few singularly creative but practically useless articles about possible causes of galactic Dark Flow
  • a financial planner who publishes a few practical articles about investing in unconventional assets
  • a popular and respected plumber who frequently posts about people's propensity to ignore leaks as well as interesting stuff he's found in drain pipes

Basically, AuthorRank digitizes a problem that has plagued the academic world for a long time: the relationship between popularity and quality.

There are other potential pitfalls and possibility for unfairness with implementing AuthorRank. Google may give special prominence to already-established authors at the expense of creating a higher barrier to entry for newer, less experienced authors to gain popularity and site visits.

Handwrite math in over 600+ applications & websites

0 comments

MathType 6.8 takes full advantage of Windows Math Input Panel (available in Windows 7 and later,) which provides support for handwritten math recognition. With MathType and the Math Input Panel you can easily write out your equations and insert them into over 600+ applications and websites.
 
Mouse, tablet, or pen
Although you can handwrite equations using only a mouse, for best results we recommend using a tablet or a pen device.
 
Opens within Microsoft Word
MathType 6.8 adds a button to Microsoft Word's ribbon, and a menu command to MathType. Each brings up the Math Input Panel ready for handwriting equations.
 
Build large equations from small handwritten expressions
While entering math by hand using the Math Input Panel is easy for simple expressions, MathType's editing comes in handy for combining simple expressions to make larger ones or when correcting mistakes. Math Input Panel together with MathType gives you the best of both worlds.
 
We're listening
You can download a 30-day full version of MathType and try MathType's handwritten math and the other new features for free. When you do, we would love to hear what you think. Send us an email or talk with us on
Facebook, Twitter, or YouTube!

Geogebra - Dynamic Mathematics for Everyone

0 comments
GeoGebra is an interactive geometry, algebra, and calculus application, intended for teachers and students. Most parts of GeoGebra are free software. GeoGebra is written in Java and thus available for multiple platforms.

Its creator, Markus Hohenwarter, started the project in 2001 at the University of Salzburg, continuing it at Florida Atlantic University (2006–2008), Florida State University (2008–2009), and now at the University of Linz together with the help of open-source developers and translators all over the world. Currently, the lead developer of GeoGebra is Michael Borcherds, a secondary maths teacher.

After a successful Kickstarter campaign, GeoGebra plans to expand their offerings to include an iPad and Android version.

GeoGebra is dynamic geometry software. Constructions can be made with points, vectors, segments, lines, polygons, conic sections, inequalities, implicit polynomials and functions. All of them can be changed dynamically afterwards. Elements can be entered and modified directly on screen, or through the Input Bar. GeoGebra has the ability to use variables for numbers, vectors and points, find derivatives and integrals of functions and has a full complement of commands like Root or Extremum. Teachers and students can use GeoGebra to make conjectures and prove geometric theorems.

Most parts of the GeoGebra program are licensed under GPL and CC-BY-SA, making them free software. However some parts, including the Windows and Mac installers, have a license which forbids commercial use and are therefore not free software.

Download Free Software geogebra here.  And GeoGebraTube is the official repository of GeoGebra constructions and GeoGebra related resources.

Mount Everest, How Tall Is It? - A Mathematics Mystery

0 comments



Last night I started to read Mount Everest, The Reconnaissance 1921 which I downloaded for free from Google Books. In the introduction there is a three page explanation of the methods used to measure the height of Mount Everest. An explanation of the differences in measurements is also provided in the introduction. Part of that explanation includes differences in snow fall, cyclical deviations of gravity, and differences atmospheric refraction when observations were made. I'm not a mathematics teacher and will never pretend to be one, but reading that introduction did get me thinking about a possible mathematics lesson.

Applications for Education
Turn to pages 10 through 13 of Mount Everest, The Reconnaissance 1921 and read about the difficulties of accurately measuring Mount Everest in the late 19th and early 20th Centuries. It's interesting to note that most accepted measurements were more than 100 feet higher than today's accepted measurement. Tell your students that Mount Everest has shrunk over the last 100 years and ask them to solve the mystery of the shrinking mountain. 

On a mildly related note and on a promotion of a Mainer note, Snow in the Kingdom: My Storm Years on Everest by Ed Webster is one of the best books ever written about Mount Everest. If you enjoy good adventure stories and or stories about overcoming personal struggles, I think you will enjoy Webster's book. For my money, and I own two copies of it, it is far better than Krakauer's Into Thin Air.
