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.
  • Why you should not put your hands in your pocket?
    People might think that you are having a lucky draw.
  • Why you should not put your hands under your desk?
    People might think that you are playing some toys.
  • Detention Club: Lifetime membership
  • Fishing Club (上堂釣魚/こっくり)
  • 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).
  • People don’t cry until they see the coffin (翻譯: 唔見棺材, 唔流眼淚)
  • 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。

發憤啊!
CH 1 聖保羅冇希望啦! 你睇吓, 人哋寶翠園影名校影英皇, 聖類斯都唔影我哋呀!
CH 2 你哋俾啲心機啦!
CH 3 DON’T CRY OVER THE SPILT MILK
CH 4 A. MATHS 都係大家係度鬥背數
CH 5 你地自己搞掂啦
CH 6 YOU WILL HAVE 3 TESTS NEXT MONDAY AND TUESDAY
CH 7 冇人咁做㗎
CH 8 PEOPLE USUALLY DO IT LIKE THIS
CH 9 我趕住上堂㗎
CH 10 數學冇 MARKING 㗎
CH 11 攞到 A 都唔恭喜你
CH 12 最多俾多十分鐘你哋
結語 香港水平真係好差! (如果你會考 MATHS 同 A. MATHS 考到 A 返學校剝佢棚牙)
