Kim on The Curious Incident Of the Dog In The Night Time

Hi guys, its me Kim again…ok basically the purpose of this post is to introduce a book to you guys… the book is titled: The Curious Incident Of the Dog In The Night Time by Mark Haddon…. I’ve already read it once but now I’m going to read it a second time to understand it better…hehe… Ok…generally the book is about this fifteen year old boy called Christopher who is autistic, understands maths and science but has difficulties understanding other human beings. He is a very logical guy who like his life to be arranged properly. When he finds his neighbour’s dog, Wellington dead, he decides to track down the killer and record it down, however along the way, he discovered things which would change his life forever….haha…ok…in order to get you guys interested, here are some of the rather logical problems he wrote in his book. Be warned that the questions below are for mathematically - inclined personnel in the class, so if you think you are not that good, please do not carry on…. (hanfeng, do not be too sensitive, I not talking about you ok?)…ok lah… just kidding…all readers are encouraged to try the questions and post your comments on it….

Question 1: You are on a game show on t.v. On this game show, the idea is to win a car as a prize. The game show host shows you 3 doors. He says that there is a car behind one of the doors and there are goats behind the other 2 doors. He asks you to pick a door. You pick a door but the door is not opened. Then the host opens one of the doors you did not picked to show a goat (because he knows what is behind the door). Then he says that you have one final chance to make your choice. So if you are that person, would you change your mind and choose the other door?

Answer: You should always change and pick the final door because the chances are 2 in 3 that there will be a car behind that door. If you use your intuition you think that chance is 50:50 because you think there is an equal chance that the car is behind any door. If you want to know how he got that conclusion, go and buy the book or I can loan it to you at $10 per week…hehe….

Question 2: Prove the following results: A triangle with sides that can be written in the form n square plus 1, n square minus 1 and 2n (where n>1) is right – angled. After that show by means of a counter example, that the converse is false, i.e. Prove that a right – angled triangle with sides which can be written in the above form is false.

Answer: Work it out yourself cos i’m too lasy to type out the solutions here, or buy the book lah…haha…

Ok, that will be all from me now…. Going to read the book second time liao…byez…
