Bertrand Russell once wrote a book entitled The ABC of Relativity. I thought it needed updating, in light of more critical thinking; and so here I have given my own ABZ of Relativity ! Twenty-six papers, from (a) to (z)  -- each fairly brief, except for papers (x) and (y) -- all of them explaining Relativity, and its flaws, in words that even a high-school student can understand. (I was thinking about the "Twin Paradox", and that got me started, as explained in paper (a), which I wrote when I still thought that Relativity was a logically coherent theory.)
