My First Blog

My First Blog by Cultural Math
 
Thanks must first go to my step-daughter, Lissa Coffey, who generously provided a portion of her web site to launch this one.  A successful published author in her own right, Lissa has been a creative force in understanding contemporary relationships on a personal level.  Her website:
http://www.coffeytalk.com/
is a source of inspiration and clarity.
     I want to acknowledge my Web Master, Brian Williams:
http://www.siteknowledge.com/
who's patience and experience were able to guide me through the barriers to bring my lectures onto this accessible platform.
     Finally, all comments, criticisms, and questions will be welcomed.  If there are any problems in viewing the chapters, let's join in a dialogue to correct them.  My hope is that you will find the same joy and intellectual exhilaration as I did when first encountering the ideas contained in this experience.
