Solving grade 8 algebra… the Enterprise way

Thursday, June 1st, 2006

I have been tutoring grade 8 math for some time. And let me tell you that it is not easy. Doing grade 8 math is one thing, but tutoring/teaching it is a completely different story. The trouble is that, by dint of having done a lot of much harder math problems as a university graduate, high school math just seems to be second nature and it has become hard to recall or even explain the thinking process behind solving simple problems.

As someone who reads The Daily WTF religiously everyday, I thought I would be less likely to fall prey to Enterprise-hype. How wrong I am! Anyway, last week I pulled a Daily WTF while tutoring math to a girl. It turns out that I showed an Enterprise solution to a grade 8 algebra problem. Here it is:

Tommy’s father is 5 times as old as he is. His mother is 2 years younger than his father. Together, the sum of their ages is 75. How old is each of them?

Having dealt with multi-variable systems of linear equations for so long, my approach was “naturally” to identify the unknown variables and then to translate the sentences into equations:

T: Tommy;s age
F: the father’s age
M: the mother’s age

F = 5T
M = F – 2
T + F + M = 75

Now we do some substitutions:

M = 5T – 2
T + 5T + (5T – 2) = 75

Finally, we solve for T, F, and M:

11T – 2 = 75
11T = 77
T = 7
F = 5T = 5 * 7 = 35
M = F – 2 = 35 – 2 = 33

I thought that this method was already pretty dirty because I haven’t even put the equations into matrix form and used the more formal linear algebra methods that I learned in college (or even the Gauss-Seidel method).

Yesterday I was tutoring the girl again. This is the first thing she said as I took out my pencil, eraser, etc: “I asked my teacher about it and she said your method is completely wrong. She said that you are teaching me stuff that I am supposed to learn only next year so she doesn’t understand why you’re trying to confuse me.” I was pretty shocked and “pwned” was written all over my face. As it turns out, what the girl’s teacher has taught (and was thus expecting) was actually even dirtier:

Father’s age = 5x
Mother’s age = 5x – 2 (since we already know the father’s age is 5x)
Sum of the ages = 5x + (5x – 2) + x = 75 (since we already know the father’s age is 5x and the mother’s age is (5x – 2)
Therefore…
11x = 77 –> x = 7
Father’s age = 5 * 7 = 35
Mother’s age = 35 – 2 = 33

Notice that they don’t bother with things such as identifying variables or substitutions. The whole problem was solved pretty much using only 1 variable from start to end. The reduction in complexity and in number of steps is pretty amusing. I think it was a good lesson (for me).

New Graduate Student for Hire!

Saturday, May 13th, 2006

Exams were over more than a week ago. 3 of the 4 grades are already posted, the only grade missing being that of the capstone project. I can be sure that I’m graduating on time because there is pretty much no way that I can fail the capstone project.

So there you go, I will be officially a new graduate student for hire on June 2, when the graduation approval will be posted.

For those of you who don’t already know, I will be receiving a B.Eng degree in Software Engineering.

I figure that besides actively job hunting through craigslist, newspapers, and whatnot; it would be a good idea to tell you, my dear readers, that I’m for hire, in case I miss some really interesting job out there. For details on my background, skills, and qualifications, you are welcome to take a look at my résumé.

Send me an e-mail if you believe I can be of service to you. Don’t leave comments as I’m afraid the anti-spam plugins may eat them.

Concordia Iron Ring Ceremony 2006

Sunday, March 26th, 2006

After 4 years of blood, toil, tears, and sweat, (most of) my friends and I finally got our iron ring this Friday, March 24th. Having this special symbol of the engineer on the pinky feels great but it’s also difficult to not notice its presence. For instance, washing your hands with the ring on really hurts because it’s pointy and you rub it all over against your off-hand.

I’m not going to talk about the ceremony itself unless there is popular demand.

The evening of celebration was great. After the ceremony and the cocktail, our class of SOEN students went for dinner at La Cabane Grecque. Being part of a small program at university is great because we can go to a restaurant and celebrate with literally all of our classmates, plus some friends. We somehow got two TA’s, Stu and Daniel, to join us. But then again, it’s not so hard to invite Stu as long as we mention “alcohol” – just kidding.

After dinner, it was drinking and dancing at New Town. Ok, I’ll admit it: SOEN guys are not the wildest dancers, with a few exceptions. In fact, the lounge was already packed with other engineering students, so ordering drinks was a feat in itself. In the end, it was more like chilling than dancing but none of us (the guys) seemed to mind. It was still cool though because Fareena joined us for a bit and we even dragged Ahmed to the club downstairs.

I’m getting a bit sleepy and I don’t know what else to write for now. For pictures, please visit the gallery. (God, I look like such a retard when I smile while being drunk.) One of the TeamSuperGood members will post or has already posted a username and password on the SOEN 490 mailing list so you can also upload your pictures.

My Coffee Table

Thursday, February 16th, 2006

After reading Kathy Sierra’s post about her coffee table, I have decided to show off my coffee table, too. Ok, I don’t exactly have a coffee table, but I’ll show you what I have on my desk anyway.

Books

  • Romance of the Three Kingdoms – one of the Four Great Classical Novels in Chinese literature;
  • Book of Han;
  • The Art of War – the original by Sun Zi; probably the best known of the Seven Military Classics; I also have another version with annotations by eleven Chinese historical figures, including the ambitious Cao Cao from the period of the Three Kingdoms;
  • Kong Ming’s Art of War – Kong Ming (Zhuge Liang‘s courtesy name) is a great politician, strategist, and tactician of legendary fame from the Three Kingdoms period; many people’s favourite character in The Romance of the Three Kingdoms, mostly for his wit, sense of honour, and loyalty;
  • Wei Liao Zi’s Art of War – Wei Liao Zi is not as famous as Sun Zi or Kong Ming, but still a great strategist and political theorist; another one of the Seven Military Classics;
  • Questions and Answers between Emperor Taizong of Tang and Li Jing – another one of the Seven Military Classics;
  • Four Booksthe reference for Confucianism;
  • The Heavenly Sword and the Dragon Saberwuxia novel by Jinyong;
  • The Deer and the Cauldron – another wuxia novel by Jinyong;
  • The Legend of the Condor Heroes – another one by Jinyong;
  • Three Hundred Poems of the Tang Dynasty;
  • Le Petit Prince – (finally some non-Chinese stuff, haha);
  • Technology & the Future – this is actually a required textbook of one of our engineering core classes; I kept it because it is an interesting read;
  • Invitation au latin, 4e – Highschool textbook to learn the Latin language and Roman history; written in French;
  • Invitation au latin, 3e – Despite the number, it is actually more advanced than the 4e.

Please note that I would rather read the Jinyong novels than watching any of these movies: Crouching Tiger, Hidden Dragon, Hero, or House of Flying Daggers. I consider the Hollywood effect dangerous and harmful to the proper development and preservation of the authentic wuxia genre.

Music

I have so much music that I can’t make an exhaustive list of it, so I’ll just list my favourite artists and albums in general.

Yellow Fever

What’s Wrong, K?

Wednesday, February 8th, 2006

Warning: May contain traces (or an abundant amount) of blatant lies. Reader discretion is advised.

The up-front answer to the question above is: I don’t know.

The night before last night I had a dream. In the dream, I was about to graduate from high school. I was riding on a yellow school bus. I was actually happy and looking forward to something as I was riding on the bus. And then the scene suddenly changed and I felt I had gone to the graduation ball; almost immediately the scene changed back to the yellow school bus. Something really weird happened in the middle of the ride: a bunch of guys, armed with baseball bat and still in their highschool uniform, tried to rush in from the rear end of the bus. I somehow managed to grab the first guy’s baseball bat and swinged it at him. I was aiming for his chest but the hit somehow landed on his forehead. For some reason, the hit didn’t break his skull; he only got a scratch. I don’t know what happened afterwards but the invasion seemed to have died off. I was hoping the bus ride would never end and then I spotted this girl who was about to get off the bus. I felt like I knew her and rushed to the front of the bus to ask her for her phone number. She promptly gave me her number and then disappeared. I don’t remember exactly if the dream stopped here or if the bus ride continued on indefinitely.

And then I woke up.

It was time for breakfast so I fumbled my way down the stairs. I looked down on the floor the whole time. At the dining table, mom asked why I’m frowning all the time. And then my dad put in the remark that “nephews resemble their uncles” and that I’m like my eldest uncle (the head of our family business), who frowns all the time and brings down the morale of everybody working around him. Dad said I should not be like him if I want to become a leader. I didn’t know what to say, so I remained quiet and avoided eye contact, as always. And then my parents drove me to the Autoparc (read “bus terminal”), and mom said I should show up more often instead of locking myself in my room, since dad is here on Chinese New Year vacation. (Note to the reader: my dad works in Hong Kong.) Then my dad said that it’s not about whether I lock myself in my room, but rather that it’s about me not telling them anything when things go wrong. Dad proceeded to remark that I seemed to have lost the self-confidence that I had in highschool. During the whole ride I was just looking blankly down at the asphalt road through the side window. What confidence? Stop saying shit about things you don’t know, old man.

As I got out of the car, I could feel the tears at my eyes. I was suddenly reminded, once again, that I have been hating my life ever since the end of highschool. I had to hold my tears back, particularly since I bumped into people I know on the bus. I remained silent during the ride. The story of the day is over at this point. I had nothing to look forward to, and as I expected, nothing special happened, just like every damn day. I went to class and went back home, and proceeded to lock myself in my room like I do everyday.

Now, it’s time to respond to questions and propositions that my friends have posed in the past few weeks, the things that I never responded to on the spot because I simply could not:

Question 1, at Les Deux Pierrots

Chris: “K, talk to her.”

Answer: Talk about what? I have nothing to talk about. Do you want me to just go through the standard routine of “Hey, what’s up,” “how was work,” etc? I have nothing interesting to talk about and I can’t tell what is interesting about other people anymore. The fact that I have ADD doesn’t help either.

Question 2, at McKibbin’s

Kat: “K, why are you so quiet?”

Answer: Pretty much the same as above. Unlike you, Danny, and Matt, I have nothing to say that may interest anybody at the table. I assure you that you don’t want to hear me talk about how Apache Tomcat is troublesome, or how ridiculous the Windows set-up is at Concordia. In fact, the reason I drink beer even though I say I don’t like drinking is because I need a means to keep myself quiet, otherwise I would start talking about things that would bore the hell out of you.

Question 3, at Second Cup

Danny: “K, you should try to go out more, even on your own. Try going to a coffee shop to study instead of staying home.”

Answer: Wonderful suggestion, but my parents want me home.

Question 4, unknown place

Chris: “K, how can you not know about <such and such> series/singer/band?”

Answer: I don’t watch television here. My mom doesn’t understand oral English or French well enough to enjoy it. In fact, even I don’t understand half of what they say on television, though I look like I can speak English and French fluently. I watch Japanese drama and anime instead because they have subtitles that are actually large enough for mom to read. Watching Japanese drama and anime led me to listen to Japanese music instead of English and French, and that’s why I don’t know music around here in Montreal.

Question 5, follow up on Question 4

“Why don’t you watch Hong Kong television instead?”

Answer: Hong Kong television and music in the recent years is pure crap. The acting is bad, the themes are unoriginal, and we have bad composers, bad singers, and bad lyricists.

Hello world!

Hello everybody,

Welcome to the new home of SwordAngel and Friends. As I announced yesterday, my Xanga blog is no longer suitable for my needs and I need a full-fledged website. However, I will not remove the old content from the Xanga blog, nor will I bother migrating it here for another two or three months.

I just got the hosting set up for me a few hours ago, so please be patient while I try to customise and expand the site in the next two weeks. The layout and content may change drastically.
