When you first see a car, would you expect it to have dents on the other side?

Quote Math Tutorial S2B: "...and the probability that a patient needs an injection after he is seen by the gynecologist is 0.002."

Birds and insects are unaffected by capsaicin. Pain induced by capsaicin is not an indication of tissue damage.

In Teck Whye, a new popiah store opened, and it is just as good as the one before! For this store, instead of peeking out and checking how many people there are, the store owner would just carry a huge bundle of chopsticks and deal accordingly.

Most popiahs are cut into 5 pieces. However, this store owner cuts the popiah into 6 pieces, which I thought is very considerate, since 6 is a multiple of both 3 and 2, so if you have 1, 2 or 3 people, you can just share any number of popiah and don't have to think about who should eat the remainder. (Unlike 5, which is a prime number.)

I was so impressed by this, I thought that this was precisely the reason why the popiah is cut into 6 pieces instead of 5. However, I decided I shouldn't argue from consequences, so I asked the store owner.

"Auntie, why do you cut the popiah into 6 pieces? Most stores cut them into 5."
"Orh, if it is too big then you have to bite it. So I cut it smaller to make it one mouthful."
"So if you could cut it even smaller, would you?"
"No, the filling will come out too easily when you try to pick it up."

And hence, 6 is the magic number arising from 2 contradicting factors, and it so happens that this particular number is also a factor of 2 and 3! This is amazing.

I was thinking that books that deal with amazing statistics might have to use the exclamation mark sparingly. It might be mistaken for a factorial.

Maybe in some African math class, you hear: "The formula for n choose r is n *click* over n-r *click* times r *click*."
