Query: From Macro to Micro - 100% Astounding!

At nearly age 70, I thought I was past any ability to absorb and comprehend anything "scientific" beyond knowing what the periodic chart contains. Bill Bryson has REALLY done it! I not only have at least a beginner's grasp of this universe of ours, I am awestruck by it and by the men and women who have dared, through the ages, to probe and poke around in it. Every time I re-listen to this amazing book, I learn/understand something new and give a hearty thumbs-up thanks to Mr. Bryson.
