New ITA Members - take note:  When trying to find something on the blog, use the Search Engine.  In the upper right-hand corner you will see an hourglass icon.  Click on that and type in the word or topic of interest.  The search engine will bring up the most recent blog first.

If you wish to read the old to new order, go to Categories and use the pull-down menu.  For example, search for Rutherford or Feynman using these two methods.

The Forum has its own search engine, unless there is something different about this new Forum.
