از قول علامه حسن‌زاده آملی نقل شده است که: بنده (یعنی خود علامه) حدود 30 سال پیش صحبتی با یک ریاضیدان داشتیم تا اين كه كلام كشید به شكل هندسی « قطاع » من از او به خاطر غرضی كه در نظر داشتم، سوال كردم:


عزيز من از این شکل چند حکم هندسی می‌توان استفاده کرد؟
گفت: شاید 7 تا 10 تا حكم.


گفتم: مثلا 20 تا چطور؟
گفت: شايد. ممكن است.


گفتم: 200 تا چطور؟ به من نگاه می‌كرد كه آیا دویست حکم هندسی می‌توان از آن استنباط کرد و توقف کرد.
گفتم: 2000 تا چطور؟ همین‌طور به من نگاه می‌کرد.


گفتم : 200.000 چطور؟ خیال می‌كرد که من سر شوخی دارم و به مجاز حرف می‌زنم.

بعد به او گفتم آقا، خواجه نصیرالدين طوسی کتابی دارد به نام « کشف القناع عن اسرار شکل القطاع » و جناب خواجه از این یک شکل، 497.664 حکم هندسی (به عبارتی چهارصد و نود و هفت هزار و ششصد و شصت و چهار حكم هندسی) استنباط کرده، یعنی قریب نیم میلیون حكم هندسی!


اين كتاب، تا کنون دوبار به چاپ رسيده است؛ يك بار با ترجمه فرانسوی و یک بار در ترکیه.
