I've never heard of Claude Shannon, till I came across this article about him on Quanta Magazine. Shannon was a genius - a scientist, an electrical engineer, and a mathematician - whose groundbreaking work on communication made possible the Information Age as we know it today.
I know I should read up more about him, about his life, and about his work (and I do intend to, soon) before I should dream about writing a post about him - but I need to make note of how much this article has inspired me. The author David Tse described Shannon as a "lone genius" who "invented the future." I'm not an engineer or a mathematician, and although I'm interested in Information Technology, it's quite unlikely that I would ever have to refer to any of Shannon's writings for my own research in social science (at least for now). But I'm drawn to his approach to the pursuit of knowledge. In this post, I'd like to list down lessons I learned from Shannon's scholarly life as described by Tse in his article. These are lessons that I hope to emulate in my own academic journey, and also in my life in general.
Lesson 1: Aim big
The article revealed how Shannon's work had been impactful since the very beginning. Upon graduating from the University of Michigan with a Bachelor's degree in electrical engineering and mathematics, Shannon wrote a thesis for his Master's at the Massachusetts Institute of Technology. The work ended up being transformative - one that "is now considered to have been the starting point of digital circuit design."
Shannon was clearly ahead of his time. But after achieving a success of this magnitude, he didn't stop there. He moved on to a bigger goal, which was to transform the way humans communicate.
Lesson 2: Look for a unifying point (this might take some time, but it's okay)
Before Shannon published his seminal work A Mathematical Theory of Communication in 1948 (which took him a decade to complete), communication systems had always been about "specific sources" and "physical medium."
Shannon was not satisfied with complying with the way things were. He was brave enough to think out of the box, to ask a question that no one in the field seemed to have asked before. He was looking for "a grand unified theory for communication," - and he found it.
I learned that this philosophy is applicable not only in academic, but also in life. I'm stating this because this lesson resonates with me in more ways than one. Recently, I've been reflecting on the value of finding a unifying point that would harmonise the different aspects of my life, as opposed to treating them as disparate entities. Modern advice seems to advocate compartmentalisation, and for a long time, this is an ideal I've been subscribing to. The pandemic, the lockdowns, having to work from home while simultaneously juggling the needs of my family have made compartmentalising very difficult - almost impossible, actually. Have I been doing it wrong all these whiles? Life consists of different aspects - yes. But these different aspects are so overlapping and intricately intertwined; I can't do one without the other. Maybe compartmentalising, drawing boundaries, and separating different aspects of life as if they're totally unconnected aren't the best ways to go. Maybe harmonising everything through one unifying point is something that I should consider doing more seriously from now on.
The unifying point might be different from person to person. I have decided that my unifying point should be my faith. I hope to write more about this in a future post.
Lesson 3: Simplicity is key
Tse wrote, "The heart of his theory is a simple but very general model of communication." Then Tse went on to describe how despite its simplicity, Shannon's theory captures some very key insights which are crucial in addressing the main issues in communication systems.
A work doesn't have to be complicated to be groundbreaking. I often think (and have been advised to think) that in order to make a contribution in my field, I need to come up with something that's not there yet. In other words, I need to create something new. But Shannon showed that sometimes what's needed is simply to point people towards the right direction. In Shannon's case, it isn't about creating something new. It's about highlighting the obvious stuffs that have gone under the radar because people have been focusing on something else that's more aligned to general intuitions of the day.
Tse commented: "Shannon’s general theory of communication is so natural that it’s as if he discovered the universe’s laws of communication, rather than inventing them."
How did Shannon do it? Through investing all his time and energy on things that he believes matter. Tse offers that Shannon had focused "relentlessly on the essential feature of a problem while ignoring all other aspects." I've been allowing too many stuffs to clutter my mind in my quest towards contributing something that I hope would be valuable. It's time to declutter my life and make things more simple so I can focus on what matters.
Lesson 4: Uncertainty is to be embraced
Shannon was the first in his field to observe that "the key to communication is uncertainty." Tse pointed out that this observation "shifted the communication problem from the physical to the abstract." Uncertainty allowed Shannon to use probability to draw up his theory of communication, which is at the same time a theory of how "information is produced and transferred - an information theory." As a result of this theory, Shannon is known as the "father of information theory."
I'm aware that this article refers to "uncertainty" and "probability" as engineering / mathematical terms in relation to communication / information systems. But at philosophical level, this truth still holds. Transferring the lesson to my own personal pursuit of knowledge, I'm reminded of instances where some things tend to be generally perceived as concrete, physical, and tangible. Treating these things as being abstract and uncertain might invite raised eyebrows. Being the amateur that I am, I often retract despite knowing that I might find something useful if I press on. It would be far from groundbreaking or world-changing, but what I would discover might be helpful in my pursuit of understanding. And this, I believe, is the main reason why I embark on this journey.
Lesson 5: Don't be afraid to be different
The article describes how Shannon's theory has led to "counterintuitive" and "unexpected" conclusions. As a result, he was deemed esoteric by fellow engineers of his time. But if it wasn't for his courage to be different, we might not know communication and information systems as we know them today. Tse pointed out that "Shannon's theory has now become the standard framework underlying all modern-day communication systems." Shannon discovered his landmark theory 70 years ago. He passed away in 2001, but his legacy lives on in the technology that surrounds us today and for many more years to come.
Familiarity gives me a safe place, a feeling of security, a sense of belonging. It takes a lot of courage to do something that no one else is doing, to be alone, to be perceived as a weirdo. But as evidenced through Shannon's life (and the lives of many other prominent scholars and inspiring people who have changed the world), taking the road less taken is not only worthwhile; it is necessary sometimes.
Pruning the Tree versus Adding my Twigs
I'll end this post with Tse's concluding paragraphs:
"When I started graduate school, my adviser told me that the best work would prune the tree of knowledge, rather than grow it. I didn’t know what to make of this message then; I always thought my job as a researcher was to add my own twigs. But over my career, as I had the opportunity to apply this philosophy in my own work, I began to understand."
"When Shannon began studying communication, engineers already had a large collection of techniques. It was his unifying work that pruned all these twigs of knowledge into a single coherent and lovely tree — one that’s borne fruit for generations of scientists, mathematicians and engineers."
Pruning the twigs of knowledge into a single coherent and lovely tree. That should be the aim.

I know this statement is so ubiquitous that it has become almost a cliche, but I still want to write it down because it's so important to me. Here we go: COVID-19 has exposed the reality of digital divide in unprecedented ways.
Sabah, my beloved home state, is not spared. Earlier this year, a video of an 18-year old girl staying overnight on top of a tree in the middle of a jungle so she can take her online examination went viral. Her story even made it to the BBC. But we know that this girl’s experience is not exclusive. In resource-scarce areas where Internet access is more a luxury than an everyday necessity, millions of children are falling behind in their studies. A recent UNICEF-ITU report pointed out that this is true even before 'pandemic' becomes a household word. For many years, hundreds of children in Sabah and Malaysia have had to endure unimaginable things for access to education. It's sad to think that it took a viral video of a girl studying on a makeshift treehouse for local politicians to finally take notice.
Scholars such as Warschauer contended that digital divide is more than an issue of the ‘haves’ and ‘have nots.’ Digital divide is clearly a sociological problem, and technocentric solutions are not the best answers. The question that I've been pondering upon is this: what will I discover if I try to understand digital divide by making sense of the realities within the social spaces that occupy it?
Bourdieu describes these realities as struggles between an evolving set of roles and relationships in a social domain. I have to embody these struggles in my years of service as a teacher in Sabah rural schools. In this social space, I've tried my best to address learning inequity by utilising digital resources at my disposal to the fullest. I have to learn how to manage the interplay between my knowledge of technology, pedagogy, and the curriculum content. I have to be ingenuous in adopting classroom approaches that make full use of 'anachronistic' digital equipment and snail-y Internet connections.
When I moved to a new social space as a district supervisor, my roles and relationships changed. My struggles in this new space consisted of assisting other teachers to manage the interplay between the three knowledge domains. These struggles inspired my study on ESL teachers TPACK mobilisation and enactment which I did as part of my MPhil. Through the findings, I learned that even teachers who had to teach in the most challenging situations thrived when their knowledge appropriation was properly facilitated.
McKinsey’s report which states (among others) that the quality of an education system can never exceed the quality of its teachers may have been a bit over-quoted (and have also sparked some debates - here's an example, and here's another one). But I think it accurately highlights teachers' true 'location' in this social dimension. It shows that teachers are at the centre of this sociological melee - whether we like it or not.
I truly hope this project can serve as a small first step towards understanding this better.
Will write more soon.

In this post, I like to write about something I learned from my 4-year-old niece Jodi, on the connection between the act of giving and making sacrifices for others.
So, my mum bought a new red dress for Jodi, which she hoped Jodi would wear on Christmas day. For some reasons, Jodi didn't like the dress. She said, "It's too big." But it's not. It's just the right size for her. She also said, "I don't think it's me" - which is very odd for a 4-year old to say. Hmm. I have a precocious niece.
So, to cut a long story short - Jodi did finally wear that dress. It happened after a long conversation with me in my room. It began with me desperately trying to persuade her - by pointing out how beautiful the dress is, how gorgeous the colour, how it would suit the theme of Christmas. "See, Creamer is wearing a red dress, too," I said, referring to myself. Jodi shrugged, told me that's great, and continued to bang mindlessly on my Yamaha keyboard on full volume.
It seemed like it was going to be a miserably unsuccessful attempt, till I felt moved to pray about it in my heart. I asked God if this can be an opportunity for Jodi to learn something about the true meaning of Christmas. I had absolutely no idea what I was praying for at that time, and hadn't a single clue why I said what I said. But right after saying Amen, I felt inspired to tell Jodi about how Moing (that's what Jodi calls her grandma) went to the mall to get that dress for her, despite her difficulty to walk. I told her that Moing paid for that dress with money (Jodi was just learning about how money works). That got Jodi's attention. She stopped playing on the keyboard and asked, "So, Moing has no more money?" I replied, "Well, she still has a little bit." Then I said, "You received lots of presents for Christmas, didn't you?" Jodi nodded. "Did you give anyone a present?" Jodi said no. "How about wearing this dress as a present for Moing?" Jodi said Yes. It wasn't an easy Yes, I could see it on her face. She had tears in her eyes when she uttered that Yes. But it was a most sincere, heartfelt Yes. Jodi really meant that Yes, and she followed it up with her actions. She allowed me to take off the old shabby green dress she had on (it was her favourite dress), and to help her put on the new red dress that Moing had spent her money on, because she loves Jodi so much.
I could still see Jodi's face as I put the dress on her - how she struggled to fight back tears. She didn't even want to look at her reflection in the mirror when I told her how great she looked. It wasn't easy for her, I know. I hugged her and told her she has the most beautiful heart ever, and that I'm very, very proud of her. Then we headed to the living room to see Moing.
How Moing's face brightened at the sight of Jodi in that red dress! Jodi gave Moing a hug and wished her a Merry Christmas. Then she skipped towards the middle of the living room, and - in typical Jodi's fashion - started to twirl around and around and pretended that she's a ballerina.
I think Jodi has decided that the red dress isn't so bad after all.
Sometimes it's okay to wear a dress that I think is too big, or that's just "not me," or that I don't want to wear because I like my old one better. Especially if it makes other people happy. And especially when it's Christmas.
And getting someone a present doesn't always have to involve giving something away. Lovingly accepting a gift - no matter how I feel about it - is akin to giving the giver a present, too.
