Dr Yang is young at heart!!!

I saw something surprising during the FYP lecture yesterday. I saw Dr Yang playing poker cards (taichi game) with a group of 3 other students. I didn't expect him to interact with the students through games!!! Haha I was giggling away. Haha Dr Yang is so playful ah... I think its more likely that Dr Rudi will play such games since he got the playful look. Dr Rudi got wrote in heis lecture notes that about the joy of winning when gambling. I know he is a curious person the first time I seen him last year liao... He is really a person who is still young at heart. Then I approach him and said to him: Dr Yang you really know how to play poker cards ah? You know statistics well." He is also interested in the games of chance as he got talk about 4D and Toto during his lecture. There is a 7x3 matrix which he showed during last year's lecture that he calculated that the determinanats of all the 3x3 sets are all calculated to be 0 so the rank of the matrix could not be 3. The he said since he got such a "lucky" matrix he should queue up at the Singapore Pools booth to buy Toto liao. Of course he got say some interesting things he found out when he was young in the FYP lecture. He talked about how vending machines work. He said that the coin slot has some electrode to detect the conductivity of the coin to make sure that the coin he used is a Singaporean coin not Malaysian or other coins since the compositions of the alloys are quite different. He also got play with the note slotting machine and tried to put in an ordinary white piece of paper into the slot, but appearantly nothing come out of the vending machine. The he found out from the vendor that the note slotting machines works on the basis of magnetism, the notes have weak magnetic fields that that machine can detect. Later, I went back to see his game, he lost that game since he has about 6 cards left when the winner is declared. The I know that he is not expert in that game, he is just curious about that game.
