I saved it on my iPhone… The whole text that is…

Many years ago, my daughter and I wereout to dinner with a guy I knew and his daughter, both kids were about 11years old. This fellow was an attorney and made some reference to the impossibility of explaining calculus to anyone, and I countered that I could explain it to the two kids. So I took a napkin, drew axes, and a curved line above the x-axis, and demonstrated how you could find the area under the curved line by using successive rectangular iterations until you hit an infinite number and then that would give you the answer. He was stunned that the kids got it right away and I was wondering if there was a book that would explain it so plainly. Apparently there is and I thank you for posting it here…

Cool, I want to check this out. 2naSalit Jul 2022 #1
