I first read about Smullyan in one of Martin Gardner's books of mathematical puzzles. I'm a fool for torturing my brain with convoluted conundrums, so when I found a copy, I was overjoyed. I devoured it in a week, and was not disappointed.This book contains Smullyan's famous logic puzzles about knights (who always say the truth) and knaves (who always lie) and all interesting combinations thereof. Apart from providing intellectual fixes for maths junkies, this book actually teaches logic through [...]
Let's get the simple stuff out of the way: Yes, this is largely a book of Smullyan's wellknown Knights and Knaves puzzles. However, it has a lot more. Beginning and ending sections include jokes about logic and logicians that teach a huge amount about logic itself. A section in the back teaches about Godel's Theorem in a simple way anyone can understand (perhaps more elegantly than Hoftadter did, perhaps not). He gives a feeling for what logic is and why we understand it the way we do.But back [...]
Konečně jsem před 14 dny v antikvariátu sehnal knížku "Jak se jmenuje tahle knížka", kterou asi mnozí znáte. Pro mě to byla novinka.Sháněl jsem ji sice pro dcerku, protože po mně pořád chtěla nějaké hádanky a mně docházely nápady, ale sám jsem knihu teď po večerech zhltnul, a musím řict, že tuto knížku jsme měl fakt číst někdy v 11, kdy bych byl asi okouzlen třeba "triky" s implikací na ostrově poctivců a lhářů, nebo ohromen mocí ekvivalence, která je [...]
A really excellent set of puzzles, for which I have only minor complaints: first, they tend to be easy, medium, or impossible. (I don't particularly enjoy the openended ones, like "what would you say." But I think it's just a time thingif I can solve the problem in 25 minutes, that's just fun. If I have to put in REAL time, then I feel like I should be doing some actual work.) Also, the set of puzzles involving insane vs. sane, liars vs. truthtellers I could never wrap my mind around. It's [...]
Fascinating book for all of us that love a good logic challenge.Great book, nicely written and with that bit of humor that everyone could enjoy.This is a nice book, one oldie but still a good reading.
This was an entertaining collection of puzzles, with some logic being explicitly taught along the way.The final Part was generally very different in tone from the rest, and the description of Gödel's actual work could have done with more unpacking, I feel. So if you're after intuitive understanding of those theorems, I could not recommend this as a sole source.Also worth noting: the book certainly shows its age with the exoticism and implied casual sexism.
This 1978 book about logic and logic puzzles made my brain work! But this book is funny too and lighthearted. And the solutions are in words not formulas or truth tables.
Lots of good puzzles, but a bit repetitive. I don't need 20 knights & knaves problems.
In this popular puzzle, a man has committed a crime punishable by death. He is to make a statement. If the statement is true, he is to be drowned; if the statement is false, he is to be hanged. What statement should he make to confound his executioner?I got this book after reading The Tao Is Silent and deciding that Mr. Raymond Smullyan must be one of my favourite people out there. A logician, a magician, a pianist, a Taoist and a mathematician? (it rhymes!)What Is The Name Of This Book? (link l [...]
Raymond Smullyan is  IMO  the most fun and creative logician who ever existed. I have always loved his books and this is no exception. It is one of his earlier ones and has a great mix of logic problems (Knights who tell the truth, Knaves who lie  sane and insane humans and vampires) as well as some talk about paradox and it concludes with his trying to make Godel's incompleteness theorem accessible to nonmathematicians.Okay  for that last part he failed since I still don't understand it. A [...]
El deixo uns dies, m'atabala massa…
This book start gently but quickly escalates in difficulty, however it is always written with very careful consideration of the beginner´s view of things. Some sentences need to be reread 10, 20 times, but the resources are there for you to understand the concepts presented, so long as one is careful and patient. Using vivid imaginative scenarios (Alice, Tweedle Dee, Tweedle Dum and Tweedle Doo; islands of Knights and Knaves; islands of insane vampires and sane vampires) Smullyan builds up the [...]
Este es un libro que pretende realizar un acercamiento a las leyes de la lógica a través de analogías en un tono lúdico para acabar culminando en una explicación del teorema de Gödel. Aunque al principio este planteamiento es divertido y ameno, es estirado en demasía cuando llega a la demostración del teorema de Gödel usando estas analogías. Este uso se convierte en abuso haciendo la demostración del teorema confusa y sin propósito privándola de la belleza y elegancia del planteamie [...]
An excellent introduction to logic, written in the form of puzzles. Unfortunately, my copy had too many translation errors and some sections (especially the bit about vampires/humans and "believing" stuff) were just impossible to decipher. So the biggest riddle is: did the author explain it badly or did the translator muddle it up? (Given the amount of corrections I've scribbled in the margins, I'll give professor Smullyan the benefit of doubt) I'd love to read it in English, so maybe I'll final [...]
I am not a logical thinker by nature, yet I recognize that logic is a useful tool in practical everyday problem solving. This is why I hold this book in high regard. It is also refreshing to read something that deals with exact things. There is a certain kind of pleasure in achieving an end instead of getting lost in vague ideas, glimpses.I only give it four due to the fact that it's a great tool, but it doesn't excite me or lead me to an exciting world. It's a refreshing and grounding activity. [...]
Delightful book of logic puzzles mentioned by Martin Gardner in his Penrose Tiles to Trapdoor Ciphers and the Return of Dr. Matrix. I checked OpenLibrary (awesome resource!) and downloaded/borrowed a copy. Kept me company on a flight from Dalkas to New York while the guy behind never stopped talking the entire trip. Talking loudly. But this was as I said, delightful.
If you like riddles that are based on stupid wordplay then you'll like this. I expected it to be a series of logical tests that grew harder and harder, each one giving you a bit more information about the next and leading you to cracking a big mystery at the end. No such luck. Instead there are pages of historical anecdotes from the author and a number of irritating riddles that basically stink of smug. Ick.
I use this to set logical puzzles to my Philosophy Students at school and it is excellent for that with a good range of difficulties. Some need updating in language (do we refer to people as normals?; some gender ideas implicit are not of the 21st Century), but there is no difficulty in tweaking casket for pirate's chest etc.
This book was so much fun when I read it, that, by the time I had finished it I found the nerve to admmit: I'm a nerd. :)But, seriously: If you like logic puzzles, you'll like this book for sure. Smullyan is a very funny author and all his works are permeated by his lighthearted spirit and creativity.
Silly puzzles and riddles I used to do when I was a kid. I think they would still be a fantastic waste of time. If only I could go back and unfigure out the answers firstI kept the book because sometimes people ask these types of questions during job interviews, btw.
The book was OK, but I expected a different sort of logical puzzles. They were monotonous and sometimes boring. Some of the problems were complex and solving them was interesting to me, but I may not read another book with no story in it again.
Už jsem ji před lety jednou četl a vydržela mi na opravdu dlouho. Vynikající jako cvičení výrokové logiky i jako zábava pro laiky na dlouhé zimní večery.Třeba se mi to bude hodit až někdy budu muset dokázat, že neexistuji. Pokud tedy nejsem lev a není pondělí
recommended by Scott Aaronson when I asked if there had been any investigation into why truth is such a mathematically strange concept.
Entertaining logic puzzles.
déprimant ce livre. on se sent idiots.
No es el mejor libro de introducción a la lógica que he leído, inicia de una manera amena pero en la medida que va avanzando el desarrollo del libro se vuelve monótono y algunas partes repetitivas.
It's monotonous and boring after few pages Puzzles are in easy or medium category
Raymond Smullyan is my Logician Dumbledore. I own and read every book of his I can get my hands on. Which is well over a dozen.
Modi d'uso:1  Aprire il libro2  Risolvere gli enigmi3  Chiudere il libro al primo segnale di noia o nervosismoRipetere i passaggi 1, 2, e 3 a giorni alterni. Meglio se dispari.
His best puzzle book. Do one every day. EVERY DAY.
