System Engineers’ tip to HKCEE/HKALE Math and Physics

Shortly after I’ve graduated with Mathematics and Electrical (and Computer) Engineering degrees, I realized a few supposedly difficult topics in Hong Kong’s Mathematics and Physics (Electric Circuits) curriculum was taught in unnecessarily painful ways.

Here’s an article I’ve written to show that it is less work to teach secondary (high) school students a few easy-to-learn university math topics first than teaching them dumb and clumsy derivations/approaches to avoid the pre-requisitesHKDSE EE Tips

Here are the outline of the article

  • Complex numbers with Euler Formula
  • Trigonometric identities can be derived effortlessly using complex number than tricky geometric proofs
  • Inverting matrices using Gaussian elimination instead of messing with cofactors and determinants
  • Proper concepts of circuit analysis and shortcuts
  • Solving AC circuits in a breeze with complex numbers instead of remembering stupid rules like ELI and ICE rules and messy trigonometric identities.

喼神 Paul Ho (God of Briefcase) PAUL HO's unHOLY QUOTATIONs

PAUL HO’s unHOLY QUOTATIONs (All in Chinglish/English because SPC is an EMI school)

  • Open the door and see the mountain (翻譯: 開門見山)
  • There is a Chinese saying … (翻譯: 俗語有話…)
  • Don’t put your hands under your desk. People might think you are playing some toys.

  • Mr. Tso, a poet who can make a poem in seven steps (翻譯: 七步成詩)
  • ICAC might stand for “I Can Accept Cash” (When he taught EPA)
  • The term “tertiary industry” (三級工業) might have a better Chinese translation…
  • ICAC might stand for “Ice-Cream And Coca-cola”
  • ICAC might meant “I Can Accept Cheques”
    (I overused his “I can accept cash” in his Econ class, so he changed it to checks)
  • Good Family Education (有家教)
  • If someone is not happy with you, they’ll say hello to your family(問候你全家).
  • If you use credit card in King Fu, they might say hello to your family(問候你全家).

  • Lots of St Pauls boys go to HKU……………………….for lunch
  • Kill the monkey to warn the chicken (殺雞警猴)

編者的話: 喼神雖然係懶,但佢嗰種老狐狸智慧喺一般學校裡面唔會學到。教得唔好唔緊要(喺聖Paul度讀都予咗至少一半係咁,自己執生係一門必修課),最緊要係佢唔煩唔管小事。喼神口賤(尤其係sarcasm)嘅功力超深,我喺佢身上學到唔少。如果你能豁開要佢教econ嘅期望,俾佢教都幾頂癮。

我認為係聖Paul教書嘅先生,教得好唔好唔係最大嘅問題; 最重要嘅係識唔識得同學生相處,同埋醒唔醒目。聖Paul嘅學生一般都唔會因為你係學校教書嘅就尊重你,都係要靠自己嘅真才實料(人際技巧係其中之一)贏返嚟。好似龍捲風呢啲得把口講,同埋超叔呢啲無自知之明嘅低B動物,要贏得聖保羅學生嘅尊重起碼要等多十世。我承認間中有啲學生會去認同啲無料到但好努力嘅先生,但我唔會咁做。

總而言之,係聖Paul教書都咪話容易,好多時都要睇天份。好似Ms Wai呢啲遲到早退嘅,偏偏係有料之人。佢火爆嘅脾氣反而教曉我有時對人好口啲好多時會幫你逢凶化吉。仲有我F.1俾飛機張教Maths大考38分,F.2俾Ms Wai教Maths大考全級第二,你話呢。

Holo Fans Club: FAN 屎來信

From: “Anthony Mak” <anthomak@hotmail.com>
Subject: 何佬啊!快D更新呀!
Date: Mon, 23 Sep 2002 18:16:19 +0800

以下兩宗乃真人真事!一定要登出!!!
或者只登他說的最後一句…

==========================

二千零一年Easter, 何佬補D.
我有D悶, 便轉身向林屴汧問: “如果你老母是x五次,咁D你老母是乜?”
佢好快答: “五既x四次.”
佢隔離的問佢講乜,佢就較大聲地覆述一次.
豈料何佬聽到,便轉身說:”做敗類都要做斯文D既….”

同年, 何佬寫十條功課在黑板上.
一位叫魏炮灰(花名)的同學說: “唔係卦! 咁多!”
何佬同佢講: “(D功課)少你都唔做啦!”
??? 係唔係精警地講粗口??????

==========================

可能何佬只是同我地班講過, 但我希望這兩件事人人(支持HOLOFANSCLUB的人)都知…
如果對上述事件有懷疑, 可以問沈宏基同李匡架… 睇我ICQinfo都得…
