PB, this is another article you wrote that puts me in ‘shock,’ shock in every good way. It tackles most comprehensibly of the topic & writes as if you were talking to eager, curious children in a field trip holding a specimen in your hand. You starts out why we want to know; you add the historical overviews for clarity as needs occur as well as tactics used for hows alternately without noticeable hump of transitions applying every bit of logical flow for the scenarios.
The vastness of the subject matters are all inclusive, and where necessary some details are added appropriately, as though all knowing eyes lining up neatly for ease to grasp. This article brought me to full view for the first time not overwhelming me different from occasions as I used to feel when I had to go through to present the same topic to advanced kids by reviewing articles written by professionals & text books. PB, you are a rare sensei so valuable to greater majority of us!
I can’t express my delighted & grateful heart enough with my limited vocabularies in my ready disposal. A walking treasure amongst of us is you! Thank you for writing this beautiful, valuable, wonderful article!
