Site Usage Continues to Grow

Statistics on this web site's usage have been tracked since the summer of 2008 using Google Analytics. This system collects a variety of data on the characteristics of visitors while still protecting their anonymity. For example, it allows us to identify the internet providers with "university" in their names who are making substantial use of our materials. However, since most materials on this site can be downloaded and hosted locally and several publishers (e.g. Norton) make use of these materials -- these statistics only provide a lower limit of usage. Interesting characterisitcs include the weekly cycle of usage (due to schools) and spikes (due to referring sites e.g. www.stumbleupon.com) and special events (e.g. equinoxes).

Usage has grown to 1.3 million visitors during 2014.

Two new Astronomy Demonstration Videos were posted during the Fall 2014 term:

  • Blackbody Radiation - where metal blocks with holes drilled in them are looked at with visible and infrared cameras.
  • Solar Tube - where a giant balloon is used to explore Archimedes' Principle and the Ideal Gas Law.

Both are available on the AU Demonstration Video Page.

Leave of Absence

Kevin Lee has taken a leave of absence from UNL to serve as a rotator in the National Science Foundation's Division of Undergraduate Education. Thus, responses to e-mail questions regarding the content of this site are likely to be even slower than usual. The availability of all content should continue as before unchanged.
