Congratulations NUS Engineers Class of 2016!


My speech at the Commencement of NUS Faculty of Engineering on July 12, 2016 at 3:00 pm.

Mr Neo Kian Hong, Member, NUS Board of Trustees, Distinguished Guests, Friends and Families of Graduands, Graduating Class of 2016, Ladies and Gentlemen, Good afternoon.

To the class of 2016, both my wife and I would like to extend our heartiest congratulations to all of you.

There are, here today, 515 graduates of which 106 getting joint bachelor’s, 3 with multi-disciplinary, 244 bachelor’s in computer and electrical engineering, 115 masters, and 47 PhDs degrees.

In a word, wow. What a fantastic collection of talent, potential and promise. A brain trust that would rival any other. The 2016 World University Ranking by Times Higher Education for Engineering and Technology, ranks NUS lucky 13th globally. Your alma mater is shining and you can rightly be proud of it! Surely that deserves a hearty round of applause!

I feel at home in the company of people who value the pursuit of knowledge with the vision to make this a better world. Engineers are dreamers, doers, builders, risk takers. Engineers are weird like that. That’s in our DNA. Our ethos.

As a child, I was enthralled with the idea of being able to walk on the moon. I wanted to become an astronaut. It has not happened, yet, but that goal has helped open up for me a vast vista of possibilities and opportunities. In its own way, that interest led me down the path of becoming a ham radio operator, 9v1hp is my call sign if you want to QSO, pursuing electrical and electronics engineering, and then computer engineering and computer science.

It was done during the time when technology, largely driven by the NASA space program’s need for high performance computing and semiconductor devices, was showing the way to bring to life, some of the ideas of what was essentially in science fiction.

It was a time when, much of the things we take for granted today, were mere ideas in Isaac Asimov‘s visions of tomorrow.

There is a wonderful interview of Asimov done by Bill Moyers in which they discuss education.

Let me quote you the following:

Bill Moyers asks:

Do you think we can educate ourselves, that any one of us, at any time, can be educated in any subject that strikes our fancy?

Isaac Asimov replies:

“The key words here are “that strikes our fancy.” There are some things that simply don’t strike my fancy, and I doubt that I can force myself to be educated in them. On the other hand, when there’s a subject I’m ferociously interested in, then it is easy for me to learn about it. I take it in gladly and cheerfully – what’s exciting is the actual process of broadening yourself, of knowing there’s now a little extra facet of the universe you know about and can think about and can understand. It seems to me that when it’s time to die, there would be a certain pleasure in thinking that you had utilized your life well, learned as much as you could, gathered in as much as possible of the universe, and enjoyed it. There’s only this one universe and only this one lifetime to try to grasp it. And while it is inconceivable that anyone can grasp more than a tiny portion of it, at least you can do that much. What a tragedy just to pass through and get nothing out of it.”

Asimov later goes on to say:

“That’s another trouble with education as we now have it. People think of education as something that they can finish. And what’s more, when they finish, it’s a rite of passage. You’re finished with school. You’re no more a child, and therefore anything that reminds you of school — reading books, having ideas, asking questions — that’s kid’s stuff. Now that you’re an adult, you don’t do that sort of thing anymore.”

Education is never “finished”. It is also not marked by getting pieces of paper, or getting a grade, or even this today’s commencement.

You may have heard of adage “sharpening your saw”. A rusty or dull saw cannot cut you a tree. Sharpening the saw is key to keeping your knowledge fresh, alive and useful. Stop sharpening, you disintegrate.

It is fitting that today’s event is called a “commencement”. You are indeed commencing your next phase of life. It is the culmination of lots of sweat equity you expended to reach a goal, and then to go on to build new things. It is a cycle, not a treadmill. It is a deliberate and positive cycle of life.

There is a word for that. Entropy. And I find entropy a fascinating idea.

You may be wondering why would I want to bring in the “second law of thermodynamics” in the address.

A tl;dr definition of the 2nd law of thermodynamics says that the total entropy of an isolated system always increases over time, or remains constant in ideal cases where the system is in a steady state or undergoing a reversible process. The increase in entropy accounts for the irreversibility of natural processes, and the asymmetry between future and past.

What was that all about, you wonder? What has entropy got to do with today’s proceedings? I hope Carnot, Clausius, Kelvin, Planck and Shannon would grant me this non-scientific postulation of their collective work.

Most of you have spent 4 years in this 111-year old institution, those getting their PhDs, a few more.

From the time you entered this school, entropy in you has been increasing. As knowledge, experience, wisdom and insights flowed from your dedicated faculty and your classmates to you – entropy increased. I say it increased because I am approximating the university as a closed system – as needed by the 2nd law.

When you take formal leave of this school’s lecture theatres, halls and labs, you will start the process of transferring the entropy – knowledge, experience etc – on to the big world outside these walls.

As you stand at the peak of this phase of your life’s adventure, the “you” sitting here is a very different “you” that entered this school. In giving of yourself to the future endeavours that you get into, you will be putting truth into the statement “that the entropy of the universe will always increase”.

By the end of this evening, all of you would hold in your hands a scroll that records your accomplishment. Savour and cherish that moment but only for a moment. It is an indication and acknowledgement that your next stage of possibilities and responsibilities has now been laid in front of you.

I am frequently reminded of a quote attributed to Thomas Jefferson, the 3rd president of the United States.

He said:

He who received an idea from me, receives instruction himself without lessening mine; as he who lights his candle at mine, receives light without darkening mine. Then there is twice as much light.

Ideas are one of those fundamental qualities that make us all human. In other words, Ideas Maketh Homo Sapiens. It remains to be seen if Artificial Intelligence can generate ideas like we do.

Each of us generate hundreds of ideas every day without breaking a sweat. Most of them are not acted upon, but do serve as building blocks for something else, all done subconsciously. The “ah, ha!” moment is an example of that subconscious confluence of ideas.

If you must judge me, judge me by how good my good ideas are and not by how bad my bad ideas were.

I know you are all brimming with ideas of what to do next. I hope you will not be distracted by, what I consider, a falsehood that ideas need to be guarded, locked up and not shared with others.

I come from the world of open collaboration where software source code, the classic example of the embodiment of ideas, is freely shared and improved upon. The business I am part of, Red Hat, built its US$2b revenue business on 100% open source code, all achieved with open collaboration on ideas and code.

My empirical experience has been that when ideas (and code) are shared, they get sharpened and the outcome is both unpredictable and beautiful. And just last week, the source code of Apollo 11 spacecraft was released and it is amazing to read the code and understand the constraints they had to work with in 1969.

Please don’t hold back on sharing your ideas.

I shall practise what I’ve preached and here’s an idea that I hope some of you will consider picking up:

Electric cars are fun, but the challenge is one of re-charging it. Re-charging is being done today by retrofitting and building new charging infrastructure. And that takes time. So here’s my idea for a start-up which I shall call PowerBuddy:

a) PowerBuddy operates a mobile, battery-powered fleet of “charging vehicles”

b) these charging vehicles are strategically placed all over Singapore

c) As a subscriber to PowerBuddy, your car will be tracked with your permission, so that PowerBuddy will know what the charge level is at all times and, based on pre-arranged settings, provide a quick (or full) recharge wherever the car is parked at.

d) You can then go anywhere and not be worried about running out of juice and more importantly, not have to wait for the current infrastructure to catch up.

I hope some of you here will pick this up, ideate further and execute PowerBuddy. I would be happy to collaborate with you on this. We are engineers, we build solutions to address problems.

Engineering is a profession that loves precision but accepts and is extremely aware of real world approximations.

Any worthy engineer will solve problems in many cases by making assumptions, to a first approximation, and then to iteratively refine the solution until it is good enough. There is a growing community of engineers who recognise that “good enough” engineering is what makes the world happen. I believe in that approximation as well.

It was the French philosopher Voltaire who said: “Perfect is the opposite of Good Enough”. The real world we live in makes it almost impossible to be perfect. Embrace good enough and we can build solutions.

We all love to succeed. But success is a poor teacher – failure, on the other hand, is a fantastic albeit cruel teacher. You can learn lots from failure, but precious little from success.

So, make sure you define success on your own terms, and work to achieve success by your own rules. Fail, fail quick and often, so that you can succeed. And in that process, to build a life you’re proud to live.

Before I conclude, from one engineer to another, well done on becoming an engineer! Together, let’s build a better world.

And finally, thank you NUS for giving me this opportunity to address this afternoon’s commencement (Update: my address starts at around 0:26).

Congratulations Class of 2016.

Thank you.
