1,000 Playthinks: Puzzles, Paradoxes, Illusions & Games

Rate this book
1000 PLAYTHINKS is the most compulsive, head-scratching, and--at 5.08 pounds--gargantuan puzzle book ever. An obsessive collection of 1,000 challenges, puzzles, riddles, illusions-both original as well as must-do classics. Jam-packed on the page and illustrated throughout in full-color, with a visual for each entry, the book, opened anywhere, is like a call to action. And once started it's hard to stop, because at the end of every successfully completed game the puzzle-solver feels smart, successful, and at one with the beauty of mathematics. Created by Ivan Moscovich, PLAYTHINKS is the first and only book where science, math, and art puzzles all come together. Broken down by chapter, PLAYTHINKS challenges with 12 basic categories, including games of Geometry; Patterns; Numbers; Logic and Probability; and Perception. A special Bonus Round is included for die-hard puzzlers who, after all that, still haven't had enough. An easy-to-read key at the!top of each game ranks its difficulty on a scale of 1 to 10. The lie-flat spiral binding makes the hefty book completely reader-friendly. So do the answers in the back.

جميل

يمكن استخدامه لتنشيط العضلات المخية بين فترة وآخرى

أنصح به الآباء والامهات لاختيار تمارين للأطفال فهو جيد وخاصة أنه يتضمن مستويات عديدة من الصعوبة

و على فكرة مفيد للأمهات يلي ما عبيلاقو وقت للقراءة بسبب الأولاد ... فورطي أولادك بشي لغز وعيري مستوى الصعوبة على حسب طول الرواية أو الكتاب اللي ناوية تقرأيه وحتشوفيهن انشغلو عنك عدة ساعات

إذا كنت من محبي الألغاز ، ألعاب الذكاء، الجبر ، الرياضيات، المفارقات، علم الهندسة ، الرسوم البيانية و الشبكات ، الأشكال و المضلعات، الأنماط، الأعداد ، المنطق و الاحتمالات.. فهذا الكتاب يفي بالغرض.

الكتاب رائع ومسلٍ
لكن الترجمة للعربية سيئة
ورد في مقدمة الترجمة أنّ الكتاب موجّه للأطفال وهذا أيضًا خطأ آخر
ليس المحتوى ما يشير إلى أن الألعاب والألغاز التي يحويها الكتاب موجّهة للبالغين فقط بل ورد في مقدمة المؤلف أنّه يوجّه كتابه هذا للبالغين وقد حان الوقت لتطبيق مبدأ التعليم باللعب على البالغين بعد الإجماع حول هذه الفكرة بالنسبة للأطفال
لذا أظن أنّ المترجم غير مختصّ بالرياضيّات وهذا ما أوقعه في الكثير من الأخطاء

Review of review?: I apologize - this may be more of a review of a review than a review of the book itself, but it MAY help your decisions. I've learned enough about the book from these reviews to realize there are some sloppy mistakes and things to watch for.

On the other hand, the review of KC Carrel below (Dec 29, 2003) ALSO contains some SERIOUS mistakes. His/her 2nd paragraph is flat out WRONG. The probability in the problem referred IS 18/36, not 12/21, and her/his discussion of "outcomes" is misleading at best. (By KC's reasoning, a two child family would have a child of each gender one third of the time, instead of 1/2 of the time, as is the case.)

You may choose not to buy the book, but DO NOT make that choice on the strength of this review alone. (I notice that everyone found it helpful and that's scary.)
