Singularity October 2010 issue

The October issue of Singularity is available for download. Get it now. It’s free.

In an act of serendipity, we have a Halloween-theme for this issue (although it’s stretching that definition). In this issue, we have:

  • A short story by my friend Grey Yuen. While the story is not scary, the character doing the monologue is. Can you guess his identity?
  • An exclusive interview with Alex Hall, a web developer in United Kingdom. Learn what it takes to create web sites in a team. We have a spider’s web on the cover. That counts as Halloween-themed, right?
  • A continuation of the Japanese learning article from September.
  • An exploration in forensic science about telling the time of death using the liver’s temperature.

Feel free to share the magazine through email, blog or other means. You’re given the right to print and distribute the magazine electronically provided you don’t change any of the content or charge for it.

Tech65 Party and PHEMAS live cutting

So last month, I attended 2 events. The first was a party held by Tech65 to thank their friends and supporters. The second was a PHEMAS live cutting event. PHEMAS stands for Pan Historical European Martial Arts Society.

So what happened at the Tech65 party? There’s beer.

and the place was packed.

Tech65 party

I remember at the party, when people asked me what I do, and I’m thinking “It’s complicated“, and I’m at a loss for words. Which was ironic, because eventually I decided to reply “self-employed writer”. What kind of writer is at a loss for words? Don’t know…

And when they find out I blog, the logical question would be, what’s the blog about? Hah! Maths and programming and other weird stuff. That oughta show’em. And show’d'em I did. I’m used to the split second motionless shock that registers on people’s faces by now. And these were people from public relations, social media and some technological fans. I didn’t expect anything less than a 2 second jaw-dropping gape.

What’s live cutting then? Real sharp swords are used to cut stuff. In this case, it was innocent plastic bottles.

And here’s Greg the instructor in full battle armour.

My only regret was that I should’ve thought of taking a picture of myself holding a sword.

Chance favours the connected mind

As a flipside to the article on deep solitary thinking yesterday, we have the “ideas having sex” idea. When ideas are connected and exposed to each other, it’s more likely that better ideas get created. Steven Johnson gave a TED talk on how good ideas come about.

You will notice that Steven’s example of tracking Sputnik eventually leading to the use of GPS was an iteration process. Ideas came up, then were acted upon to test them, which led to further ideas bubbling up.

Maybe I’m wrong, and the ability to hold on to a thought or idea long enough to contemplate it is no longer needed. Or maybe it’s a cycle, where you do deep thinking, share your ideas, get feedback, then reflect on the new ideas. Or maybe in the future, we do our thinking in tiny chunks. Everyone just blurts out their first reactions, no one person actually consolidates it, but eventually, a solution forms somewhere down the road. Every problem becomes open-sourced.

Will we have a SETI@Home-like project where every human being volunteers a bit of their time to do “first reaction thinking”? Will we be reduced to machines, interchangeable for the capacity to think in short spurts?

We share ideas because that’s how they get better. We also need someone who can sit down long enough to think through the bettered ideas into something useful and act upon them.

Fear of your own thoughts

Do you think? I mean like sit there quietly and think. Maybe it’s to solve a maths problem. Maybe it’s to come up with a few points to a PowerPoint presentation. Maybe it’s to reflect on a painting you saw in a museum last week.

Have you ever had a fear that you’re not doing anything productive while you’re thinking? Because you don’t seem to be doing anything. Because you’re not scribbling something, reading something, researching on the Internet, writing an article, or hammering a nail (hey I’ve got engineers reading my blog, maybe there are home builders too…).

Are you afraid of being alone with your own thoughts? Or even simply being alone?

The other day, there was a scheduled power cut at my apartment block. Since I couldn’t do any work (no power means no computer and no Internet), I thought I’d go to the library instead. As I got ready to leave, the power cut at exactly 9am, as scheduled. I know, because the fish tank in the living room turned silent. The pumps and filters that kept the fish tank aerated and clean stopped working. I remembered it clearly, because the silence was almost deafening. I don’t remember my house being that quiet.

Have you ever tried meditation? For our purposes, let’s say it involves sitting in a quiet place, and to not think of anything or to think of only one thing. And let me tell you, thinking of nothing or only one thing is harder than you imagine. The easiest method is to just focus on your breathing. You’re not supposed to worry (or even register in your mind) about the laundry not being done, the itch on your back, the wind blowing through the window, or the minute hairs moving on your hand.

Why is it hard? Because your brain, given little external stimuli, will start feeding you with something, anything. Under those circumstances, your brain can only feed you thoughts.

I bring up meditation because deep thinking resembles it. I remember asking my university professor something (can’t remember the question though), and he sat in his chair, leaned forward, placed his elbows on his knees, and just stayed there. Motionless. After maybe 10 or 15 seconds, he looked up and answered me.

Sometimes, I stay motionless when I was programming. I could be staring into the screen or off into the empty space for up to half an hour. Maybe designing a user interface, maybe pondering a piece of code, maybe just figuring out the best method to solve a problem. I had to remember to swivel in my chair or drum my fingers or something, so my colleagues know I’m alive (or still working).

The whole point is, can you do sustained thinking? 15 minutes? Half an hour? I believe this is important. Our problems are getting more complex. Attention spans seem to be getting shorter. The amount of information we’re allowing ourselves to consume is growing exponentially. Thinking is hard, so we allow others to think for us. I doubt the time needed to think can be as short as that needed to type out a Tweet… oh look, squirrel!

Maths, context and culture

I was reading this post by Dan Meyer on pseudocontext in maths problems.

If we invite pseudocontext in our classrooms without condition, it becomes harder and harder to tell the difference between the real and the unreal.

Back when I was young, a lot of maths problems made little sense to me. In those days, the maths syllabus up to primary 6 (at 12 years old, or grade 6 if you’re in America) wasn’t particularly hard. At least to me. I’m not bragging, I’m just saying that the education system made things more difficult by introducing word problems. The epitome of conquering a maths exam paper was solving all the word problems at the end.

Word problems were created to introduce another element into elementary math (to make them difficult?). They added language. Suddenly it was something like:

John, Fred and Ken had $5 total. John bought 10 red marbles and Fred bought 12 blue marbles. If 1 red marble costs $0.10, and 1 blue marble costs $0.15, how many blue marbles can Ken buy if they still want to have $1 left?

Your command of the English language became a factor. But it was still ok, because the wording usually formed a pattern. It was marbles, people’s ages, number of apples or oranges in the basket, or some such. In a normal situation, if I really wanted to know your dad’s age, I’d just go ask him. I don’t really need to infer that your dad is 2.5 times your age, and then I figure the answer out (assuming I know your age).

Students here kill each other with A’s

Now if you don’t already know, it’s bloody competitive here in Singapore. Students are afraid of not doing well in school, of heads shaken by their friends, teachers, parents and relatives. Parents send their children to tuition classes (in addition to the normal school classes), regardless of their children’s grades. If the grades are bad, then improve them. If they’re great, great! Now perfect them. Go do your ten year series!

I went to tuition classes till I was 10 years old (primary 4 or 4th grade). I stopped because my dad couldn’t afford to pay for the classes. Being able to eat and pay the bills were more important. It’s a good thing I was disciplined enough to get good enough grades (and imbue enough motivation for all subjects, not just maths).

When I was in university, to supplement the cost of education, I looked into giving tuition. I was surprised that everyone from primary one to university level (?!) were asking for help. Let me just say, I make a lousy tuition teacher. I don’t really know the current syllabus well enough to help the students. Once, I brought up the subject of video games, using the position of battleships to illustrate … something. I can’t remember. I think it was x- and y-coordinate stuff. I was trying to interest the young boy I was teaching. It fell flat. I suck…

The Singapore Math Method

Which brings us to curriculum. It turns out that under the Singapore maths curriculum, Singapore students rank high for maths internationally. It’s so good that America has adopted the method. There’s even a name for it: Singapore Math Method. Let me tell you, I’m simultaneously amused and confused.

I’m even more surprised that Israel adopted the method in 2002, translating the textbooks to Hebrew. I was browsing in the bookstore reading Start-up Nation (Amazon link). It told a story of how Israel, being surrounded by hostile countries, had to innovate hard. Their brightest people are in the universities doing research and are also in the top military ranks. The book told a story of how the “flat” nature of their military translated to their way of doing businesses, in particular start-ups. My friend Christopher told me that per capita, Israelis were the richest in the world. It’s their culture that made them more inclined to creating wealth. I was also told about the Jewish mother syndrome… So I’m a little surprised that this group of people want to know about our (Singaporean) method of teaching maths.

I still believe in solving real world problems. I believe we’re not injecting enough curiosity into our students. That Singapore Math Method seems to have less force-feeding of concepts, and more of coaxing the student to question. The Singapore culture doesn’t seem to require curiosity for the students to do well (have I mentioned the parents are bloody competitive?). Hopefully, that’s changing.

This is going to be a cynical view, but I think most Singaporeans are striving for wealth, and wealth alone. Wealth translates to a better life. There’s nothing wrong with that. Singaporeans strive hard to attain wealth so they can forget about (seemingly) miserable lives. Ok, let me take that back. Apparently, Singapore is one of the happiest places in the world. There’s a “but” though…

Singapore ranks high on evaluated happiness, but not on experienced happiness

Alright, this is starting to depress even lil’ cheerful me…

So. Problems are formulated, and then given to our students to solve. But they have to learn how to formulate problems too, and that comes from asking questions, from being curious, from being disciplined and persistent. And that comes from cultural and societal influences, not from educational systems.
