# Pure Maths

Past papers 15

“Past papers” means “past HKCEE/HKAL examination papers”. The topic is for Hong Kong students who are facing HKCEE or HKAL. But the general principles can also be used for tackling other public examinations.

（LWT：我都不知道如何讀 …）

（LWT：我覺得呢 … Pure Maths（純數學）中，好像每一道題目都有新的做法 …）

（LWT：好像每一道題目都有新的做法。做新的題目時，我不能用我已知的方法技巧，試試可不可以做到。）

（LWT：哪如何歸納呢？是不是讀完一課後，自己就嘗試歸納？）

（LWT：即是記錄自己用過哪幾個技巧？）

# The primordial forces

* Programming in Lisp is like playing with the primordial forces of the universe. It feels like lightning between your fingertips. No other language even feels close.

# Nerd 3

.

As a thirteen-year-old kid, I didn’t have much more experience of the world than what I saw immediately around me. The warped little world we lived in was, I thought, the world. The world seemed cruel and boring, and I’m not sure which was worse.

Because I didn’t fit into this world, I thought that something must be wrong with me. I didn’t realize that the reason we nerds didn’t fit in was that in some ways we were a step ahead. We were already thinking about the kind of things that matter in the real world, instead of spending all our time playing an exacting but mostly pointless game like the others.
