The fundamental building blocks of number system, prime numbers are special. It means 2011 can not be expressed [...]

Dangerous Mind – Mathematics and Insanity

Problem solving is a top-notch skill. All of us face problems, in work, in life and every day happening. Jokingly mathematicians identify the following stages of a problem solving: Identifying the problem (includes preparation, collecting information, identifying challenges and risks) . Attacking the problem (use existing tools, techniques to derive new method). Get vigorous, consciously. [...]

Math Games for Children

Games are the sure shot fun way to teach some thing. And math is one of the top-notch skills one needs to own for being successful in any career. Imagine if playing games hone your mathematical skills. As a kid I grew up learning few board games which helped me to understand the most basic [...]

An exciting book written on educated guessing, problem solving  and rough calculations by MIT Prof. Sanjoy Mahajan. Prof. Sanjoy Mahajan wrote Street Fighting Mathematics – The art of educated guessing and opportunistic problem solving book out of [...]

Instant Insanity – A Graph Theoretic Wonder

Instant insanity is one the many games involving sound mathematical principles. In particular it involves graph theory to solve. One of the mathematics most powerful tool – representation theory is used. As you are aware of, what looks like a strange problem is transformed into totally a unrelated problem in another field because of the [...]

Urinal Protocol and Hilbert’s Hotel

There are two things I read this week and thought weird. One is about ‘Urinal protocol’. Urinal protocol vulnerability For those who don’t know what it is, read here. The point is, in a public rest room, every male should take due effort to use the buffer urinal. There are un-written rules, protocols people follow [...]

And hence the sudoku is solved

J. F. Crook has provided a pencil and paper algorithm for solving the most celebrated puzzle – sudoku. This mathematical method explains how preemptive sets are used in solving them. I think, for solving sudoku this way you might need to know more math than what you need to know for sudoku.
