Query: A+ Book....Phenomenal!!!

Best book if you want to self-educate yourself advanced math and physics. Starts where high school left off. Seamless integration of math and physics topics. Lucid, I repeat LUCID, explanation of concepts that other writers seem to dress up in incomprehensible thickets of verbiage in the guise of 'rigor'. In contrast, this particular book's authors come from the traditions of Feynman...the 'great man for clear explanations' Congratulations on a job well done!!!
