Lovely article with some interesting puzzles near the bottom (and top). When I was young, Martin Gardner's puzzle books, along with Raymond Smullyan's 'What Is The Name Of This Book?'[1], introduced me to logic and to the fact that mathematics could be fun - something that was very influential in going on to study maths and computer science. I thoroughly recommend checking them out…
on “Martin Gardner, puzzle master extraordinaire” ↗"What Is The Name Of This Book?" by Raymond Smullyan is a great book if you like puzzles or want a playful way to improve your logic/reasoning skills. It does a really good job of incrementally building up to more complicated problems.…
on “Ask HN: Books that change your way of thinking?” ↗Challenged by What Is the Name of This Book but loved it. If Hofstadter hadn't changed my life forever, maybe Smullyan would have.
on “Raymond Smullyan has died” ↗I finished What is the name of this book? by Smullyan and am halfway through The Lady or the Tiger? (also Smullyan). I'd read the latter years ago along with one other book of his. I'll find out which it was when I get to it and recognize the…

on “They're Made Out of Meat” ↗I don't have much to add, except that when I read his books -- for me, the ones I fell in love with were The Lady or the Tiger, What is the Name of this Book? and To Mock a Mockingbird -- I felt I was communing with a spirit for whom wit, delight, charm and generosity were one. I'm delighted, and not a bit surprised, to hear he had this sort of presence in…
on “Raymond Smullyan has died” ↗my daughter and i have used "what is the name of this book?" and now "to mock a mockingbird" as the first slot in the day for her homeschooling. his books are really wonderful. public schools should be lousy with them.

on “Raymond Smullyan has died” ↗Raymond Smullyan's riddles book What is the Name of This Book paradoxically refers to itself in its title.
on “Ask HN: Examples of Recursion in Literature or Cinema?” ↗Two other stories by Raymond Smullyan: - In "What Is the Name of This Book?" he recalls being introduced to logic at the age of six. - In "The Lady or the Tiger?"

on “Attention Spans for Math and Stories (2019)” ↗…of my favorite Smullyan works is the lesser-known 5000 B.C. and Other Philosophical Fantasies. Here's one of the more amusing anecdotes from that book: In item #249 of my book of logic puzzles titled What Is the Name of This Book?, I describe an infallible method of proving anything whatsoever. Only a magician is capable of employing the method, however. I once used it on [noted philosopher] Rudolph Carnap to prove the existence…
on “Raymond Smullyan has died” ↗…AI can think in models but so far, not but still an impressive assisting tool if you take care of its limitations. Another point where it lacks is in logic, my daughter has a lot of fun with the book "what is the name of this book?" but she was struggling with the "map of baal" explanation, her the answer was a certain map, yet the book had another answer, I had a third one as I interpreted a proposition. I never got an answer…
