I have a LOT of non-traditional explanation and resources on LOGARITHMS.  The easiest way to find the website is to use the easy-to-remember and easy-to-spell link www.mathinlivingcolor.com.  Near the bottom of this page is a link that takes you to my Homepage.  


Once you find my Homepage, look for the link "Basic, Intermediate, and College Algebra: One Step at a Time."  Choose "College Algebra" and look in Chapter 4 for the chapter on Logarithms.  I think you will really like the "Math in Living Color" pages that go with these sections.  In addition, I have a 2 FREE videos on this topic that were made in my younger years before I retired.  To see the videos, look on my Homepage for the link "Rapalje Videos in Living Color."  Choose College Algebra, and look for the video on "Logarithms."
