Rambow’s Rules for Life

Shortly after my son was born, I began drafting a letter to him — something I hoped he would remember me by long after I was gone that would also help him live the best life possible. The letter included many of the most important lessons I’ve learned in life — advice on how to be happy, healthy, and successful. My hope was that it would help him avoid many of the mistakes I made. For anyone who might be interested, here is the advice. I’ve divided it into three parts: (1) keys to success, (2) keys to happiness, and (3) miscellaneous advice.

KEYS TO SUCCESS

  1. BE INDUSTRIOUS. Let your natural, default state be one in which you are always creating or learning something of value. If you’re always productive, success will be almost automatic, and you’ll never regret how you spent your time. Build things. Write. Learn new skills or languages. Keep a list of things you want to accomplish, and make sure you’re always chipping away at it. Don’t waste any time, because time is the most precious thing you have. This doesn’t mean that you should be a workaholic; quality time with friends and family is vital as well. Relaxation and recreation, in moderation, are not a waste of time; in fact, they can help replenish your well of creativity and make you even more productive — and creative pursuits are a big part of what makes life meaningful.
  2. CULTIVATE USEFUL SKILLS. Skills give you freedom and power. If you’re good at coding, you have the freedom and power to create new software. If you speak a foreign language, you have the freedom and power to live and succeed in a different country and to make friends with people you otherwise wouldn’t even be able to communicate with. Look around and think about what skills you’d like to have. What skills are employers looking for? What skills match your interests, talents, and affinities? What skills will give you the freedom and power to get a good job and earn a good wage? What skills will give you the freedom and power to do the things in life that you really want to do? It’s not just about work; there are plenty of skills apart from work that make life more enjoyable and fulfilling.
  3. BUILD PERSONAL CONNECTIONS. Cultivate and maintain lifelong friendships and business relationships. Always be engaged in your community — at work, at school, in your neighborhood — and make positive contributions while also building useful connections. Help others, and don’t hesitate to seek their help as well. It’s not about using people; it’s about being part of something bigger than yourself — a community that benefits everyone. Make sure the relationships are genuine; care about the people in your network, and learn to speak their love languages. Good relationships will help you not just to be more successful, but to be happier as well — because companionship is another big part of what makes life meaningful.
  4. BE PROACTIVE AND ASSERTIVE. If you want something to happen, make it happen. Don’t wait for opportunities to come your way; rather, actively seek them out and create your own opportunities. Just being good at what you do isn’t enough. People won’t come along and offer you a dream job just because you’re an excellent student. Figure out what you want; then figure out what it will take to get it; and then do it. You have to be willing to take risks. I was never very good at this, and I regret that I didn’t understand earlier what it meant to be proactive. I was a “great” student who always made good grades, and so I always got funneled automatically to the advanced classes at the next level. I made very few decisions on my own. I expected everything to be handed to me automatically because I was a good, hardworking student. But when it came time for me to graduate from college, I didn’t have a plan. Other people had made plans much earlier on: medical school, graduate school, law school, internships, and engineering jobs. While they were starting their dream careers, I still had no idea what I wanted to do. That was a huge mistake — one that I don’t want you to make as well. So, figure out what you want to do, and make it happen.
  5. EXERCISE YOUR MIND. Your intelligence level is not fixed; never stop raising it. Push yourself to master knowledge and skills that are difficult to understand, and you will become smarter. Stay in the “zone of proximal development” — the region where things are neither too easy nor too hard, but challenging enough to make you grow. If you feel that everything you’re doing is easy, then you’re not challenging yourself enough, and you should find more difficult problems to tackle. Actively and intentionally develop your problem-solving, comprehension, and communication skills. Be informed, be discerning, and expose yourself to a variety of viewpoints.
  6. PROTECT YOUR HEALTH. Take good care of your physical and mental health. Poor health is an obstacle to success, because health problems can eat up time, energy, and money that could be better spent on other things. You can’t control everything about your health, but there is plenty you can do to maximize your chances of staying healthy. There are four keys: diet, exercise, sleep, and companionship. Don’t pollute your body with smoke, excessive alcohol, or too much sugar and fat. Don’t eat too much or too little. Play sports that exercise your heart and lungs; lift weights enough to be strong; stretch enough to be flexible. Take care of your appearance so that you will always feel good about the way you look. Get enough sleep so that you’ll be mentally sharp and have plenty of energy. And surround yourself with people who push you to be a better person and make you feel good about yourself. Your health has multiple components, all of which will affect your success; don’t neglect any of those components.
  7. MANAGE YOUR MONEY WISELY. Always spend less than you earn. Whenever you receive money, save and invest a portion of it. Obtain assets, and avoid liabilities. An asset is an investment that brings more money into your pocket. A liability is something that drains money out of your pocket. An expensive car is a liability, not an asset. A fancy house is a liability, not an asset. A stock or mutual fund that grows in value and pays dividends is an asset. A house or condo that you rent out is an asset. Don’t worship money, but manage it wisely so that you’ll always have enough to take care of your family and do things that you enjoy.

Of course, success is not the only important thing in life. There are plenty of highly successful, wealthy people who are miserable, who hate life, and who drag everyone around them down. Don’t be one of those people. Happiness is more important than success or wealth — though of course, success and wealth can make it easier to be happy. Below are some additional principles that will help you to be as happy as possible.

KEYS TO HAPPINESS

  1. Surround yourself with cheerful people who work hard and like to help others. The friends you choose will have a tremendous influence on the kind of person you become. Make sure you’re always surrounded by people who make you a better, happier person. If you surround yourself with unhappy people, then you’ll be unhappy too. If you surround yourself with lazy and unsuccessful people, then you’ll be lazy and unsuccessful. On the other hand, if you surround yourself with people who are just like the person you want to be, then you will become the person you want to be. Here’s a good rule of thumb: If you like the person you are when you’re with someone else, then keep spending time with them. If you don’t like the person you are when you’re with someone else, then stop hanging out with them.
  2. Don’t compare yourself to others. There will always be people above you and people below you; people who are faster, and people who are slower; people who are richer, and people who are poorer. If you focus on the people who are “ahead of you” in life, it will be easy to become afflicted by envy, bitterness, and despair. If you focus on the people who are “behind you,” you may be tempted to feel an undeserved sense of superiority and pride. Neither is beneficial. Focus instead on being the best you can be. Take satisfaction in your own unique identity, the special roles that you fill, and the never-ending process of striving to become a better person.
  3. Find enjoyment in your present circumstances. A lot of people spend too much time focusing on what they want next. First, they can’t wait to grow up and become an adult. Then they can’t wait until they finish school. Then they can’t wait until they have a job. Then they can’t wait until they’re married. Then they can’t wait until they have kids. Then they can’t wait until their kids grow up. Then they can’t wait until they retire. Before they know it, their life is over, and they didn’t enjoy much of it because they never savored what they were doing in the present. Satisfaction was always one step ahead of them, so they never reached it. Instead of dwelling on where you want to be next, focus on where you are now. Find enjoyment in the process rather than the goal. If you’re doing the right thing now, you’ll end up in the place where you want to be next.
  4. Hold onto the good, and let go of the bad. Your memories will be your most precious treasures. The ones you choose to focus on will determine whether you are happy or bitter. Every night, as you drift off to sleep, open up your treasure chest of happy memories, and fill your heart with them. Think back on the bad times just enough to learn from them, and then let go of them so that they will never bother you again. This can be difficult to do, since we can’t always control our thoughts; but what we can do is notice negative thoughts when they arise (without passing judgment), notice how they make us feel, and then redirect our attention toward something more positive. Do not try to stop thinking about bad things. (There’s a classic joke about this: If someone tells you not to think about an elephant, they have just made you think of an elephant — and so it is impossible to avoid thinking about an elephant by trying to avoid thinking about one. In the same way, if you are focusing your attention on trying not to think about something painful, then you will necessarily be continuing to think about that painful thing.) Instead, start thinking about something else; the only way to get rid of negative thoughts is by replacing them with something positive. Don’t punish yourself for mistakes you’ve made. If you feel bad about them, then you’ve already learned from them. Let go, and move on.
  5. Never allow bitterness, resentment, contempt, or anger to take root in your mind. Don’t let any event — a horrible illness, the loss of a friend or loved one, or any kind of conflict or tragedy — make you bitter. Your life is too precious and too short to allow any significant part of it to be ruled by bitterness or anger. You may not be able to stop yourself from having these feelings temporarily, but the important thing is that you not let them take root and grow. Notice the bitterness or anger when it arises, and then let go of it and actively replace it with something positive.

Here are some other miscellaneous pieces of advice that I think are extremely valuable. Many of them are things you’ve heard me say many times, and I repeat them here unapologetically. They will also contribute to success and happiness.

OTHER MISCELLANEOUS RULES

  1. Never complain or make excuses, even when there are legitimate complaints and excuses to be made. Complaining is unattractive. If you have a positive attitude and lift others up rather than dragging them down, then people will like you more, and you’ll be happier and more successful. Bad attitudes are contagious; if you get infected by one, try to cure it before you spread it around. And avoid catching a bad attitude from others, just as you would avoid catching a cold from them.
  2. Observe other people carefully, and pay attention to their motives. Do this in both the short term and the long term. It will help you identify dangerous people, and it will also help you make deals with people. If you’re on a bus and you see a woman taking care of her baby, then you know what is motivating her: the desire to keep her baby safe, happy, and healthy. She’s not going to hurt someone else on the bus unless she feels threatened or desperate; and if she does feel threatened or desperate, that’s something you should be able to see. But if there’s a young man who is all by himself and is eyeing everyone else’s bags, purses, and pockets, then maybe he’s looking for something to steal. Pay attention to what people are looking at. Watch their eyes, watch their body language, and listen to their words. Think, what is this person trying to accomplish right now? This habit can be useful in working with other people. If you know what someone really wants, you can make a deal with them; they might be willing to do something for you if you help them get what they want. Just be ethical, and avoid shady deals that will cause trouble.
  3. Don’t be afraid to take risks. This old saying is true: “Nothing ventured, nothing gained.”Often, it’s worth it to give up something of value to get what you want, just as you might sacrifice a valuable piece in chess in order to win the game. Just be wise, not reckless, in the risks you take and the sacrifices you make.
  4. Be a player in life, not a spectator. Theodore Roosevelt put this idea best in the following quote:
    It is not the critic who counts; not the person who points out how the strong one stumbles, or where the doer of deeds could have done them better. The credit belongs to the one who is actually in the arena, whose face is marred by dust and sweat and blood; who strives valiantly; who errs, who comes short again and again; who spends oneself in a worthy cause; who at the best knows in the end the triumph of high achievement, and who at the worst, if one fails, at least fails while daring greatly, so that one’s place shall never be with those cold and timid souls who know neither victory nor defeat.
  5. Avoid motivated reasoning. “Motivated reasoning” is one of the most harmful things to human society. It undermines truth itself. And yet it is something that we do naturally, so we must watch for it in ourselves and try to avoid it. What is it? It’s the tendency to fabricate logical reasons for believing the things we want to believe. The following statement is counterintuitive but true: Intelligence doesn’t necessarily bring you closer to the truth; rather, it just enables you to construct clever reasons to continue believing the things you want to be true. A man once said to me, “My IQ is just a few points shy of Einstein’s. If you give me any argument against the Bible, I’ll be able to prove it wrong.” All this really meant was that he was committed to using his high intelligence to buttress the dogmas he had already decided were true before examining the evidence. His mistake was this: He never approached the Bible with an open mind and used his intelligence to consider the question, “What is actually true?” Instead, he was tackling the question, “How do I interpret the evidence in a way that won’t conflict with my cherished beliefs?” If he had been born into a Muslim family, he would have said the same about Islam: “If you give me any argument against the Qur’an, I’ll be able to prove it wrong.” And indeed, there are many people just as intelligent as he is who are just as certain that the Qur’an is true and whose arguments for its veracity are just as clever. The honest pursuit of truth is NOT about searching for evidence to prove your hypothesis correct. It is about going where the evidence takes you — whether that’s where you wanted to go or not. Good scientists search just as hard for evidence that will disprove their theories as for evidence that will support them.
  6. Avoid tribalism of all forms — especially political, racial/ethnic, and religious tribalism. Just like motivated reasoning, tribalism is tremendously harmful. It exists naturally within you, and you have to work hard to avoid falling victim to it. What is it? It’s a tendency to fall in line with people in your group — something we all do without being aware of it. Think about this: If you know what people believe about one particular issue, such as abortion, then you can usually guess what they believe about most other issues — even totally unrelated ones. Take guns and abortion, for example. You might think that someone who wants to protect the lives of unborn babies would also want to limit the availability of guns. But as it turns out, most people who are against abortion are also in favor of widespread gun ownership. And the reason is purely political. Most people are born into a political tribe, or they join one when they grow up. They think they’ve arrived at their beliefs through logical reasoning, but the actual truth is that they’re going along with their tribe, and they’re just employing motivated reasoning (without knowing it) to convince themselves that they arrived at their positions via rational thought.
  7. Become adept at defusing tense situations and disarming agitated people. It is in our nature to escalate tensions and repay offenses with greater offenses. Be strong and creative enough to step out of such destructive cycles. Interactions with people are like games of chess. You can be a slave to your nature and make expected moves that bring about expected conflicts — or you can master yourself and make unexpected moves that take everyone by surprise and change the direction and outcome of the game. In fact, most people are trapped in petty games without even realizing it. They are trying to score points for themselves and for their tribe. They spout insults and broadcast false virtues (which will win them esteem in the eyes of their tribe) without any regard for what is actually true. They cannot see their way to exit the game and play by a different, higher set of rules, putting an end to the point-scoring and the tribalism. Once they are locked in conflict, they cannot even see the possibility of ending it and working together. They cannot see the possibility of admitting they are wrong or apologizing. Get in the habit of watching for ways to transcend the games that others play. This is how you turn enemies to friends. This is how you get people to come together and accomplish more than anyone ever would have believed possible.

Daddy, Are You Dying?

“I can’t see the stars,” I said.

I was talking about the glow-in-the-dark dots on my son’s new space-themed pajamas. He was excited about them, as only a two-year-old could be, and he wanted to show them off to me. But they were invisible to my eyes.

“Why?” he asked.

I thought for a moment. I would probably be able to see them in a few seconds, once my eyes had adjusted to the darkness; but it also occurred to me that my sight just wasn’t as good as it used to be. Eliot’s was better.

“My eyes aren’t as good as yours,” I said.

“Why?” he asked.

Once more, I paused.

“Because my eyes are old,” I said at last.

Why are your eyes old?” he asked.

“Because I’m old!” I said.

This time, Eliot was the one who paused. During the silence, I began to make out the stars on his shirt, but I couldn’t see the expression on his face as he looked at me, processing what I’d just told him. When he finally answered, his voice was much quieter and more serious than it had been just moments before.

“You’re dying,” he said.

I stared into the darkness. He was only two. He had seen plants and flowers die, but as far as I knew, he’d had no cause to think about people dying. Had someone told him about the connection between old age and dying, or had he just known? I suddenly had a spooky feeling that perhaps Eliot’s mind was connected to some well of universal truth—a source we all begin life connected to but then lose touch with as we grow out of childhood.

“Daddy, are you dying?” he asked.

“No, buddy,” I said. Not yet.

After we said good night and I closed his bedroom door, I couldn’t get his little voice out of my head. Daddy, are you dying? Just how much did he know?

It wasn’t until the next morning, as I was walking him to the playground, that I would get another hint as to what was going on in his mind.

“Daddy,” he said, “I don’t like you.”

“Why?” I asked.

“Because you’re old.”

I laughed, even though it actually hurt a little.

“Well,” I said, “when you get old, I will still like you.”

He looked up at me, eyes narrowed.

“No,” he said. “I will still like you.”

A moment later, he was running toward the slide.

Your Dream Lives On

I’m proud to share “Your Dream Lives On,” a new song that I recently completed. You can watch the music video on YouTube (below) or buy the mp3 here.

And here are the lyrics:

She was just a little girl,
Dreamin’ bigger than she knew she should.
She’d seen how cold the world could be
And had in mind to change it if she could.

She said, “I’m gonna sing the song that will save the world.
I’m gonna speak the words that will heal our souls.
I’m gonna light the fire that will burn away the darkness.
I’m gonna lead the march that will make us whole.”

Well, life made her a widow
With a baby boy to bring up on her own.
And she spent all of her energy
Providing for that boy till he left home.

And all too soon, the years had slipped away,
And she lay dying in her bed.
As the tears were streaming down her cheeks,
She looked me in the eye, and then she said:

“I searched so hard but never found
Those healing words. I never sang that song.
I never lit that fire, never led the march,
And now my dream is gone.”

And I told her, “Mama, your dream will never die.
I watched you live your life. You made me who I am.
I heard you sing your song and saw you lead the march.
You lit the fire inside of me, and so your dream lives on.”

“And now I’m gonna sing the song that will save the world.
I’m gonna speak the words that will heal our souls.
I’m gonna light the fire that will burn away the darkness.
I’m gonna lead the march that will make us whole.”

Well, that was forty years ago,
And now it’s time for me to go as well.
As the tears come streaming down my cheeks,
I take my daughter’s hand, and then I say:

“I searched so hard but never found
Those healing words. I never sang that song.
I never lit that fire, never led the march,
And now the dream is gone.”

And she says, “Daddy, your dream will never die.
I watched you live your life. You made me who I am.
I heard you sing your song and saw you lead the march.
You lit the fire inside of me, and so your dream lives on.”

“And now, I’m gonna sing the song that will save the world.
I’m gonna speak the words that will heal our souls.
I’m gonna light the fire that will burn away the darkness.
I’m gonna lead the march that will make us whole.”

“I’m gonna sing the song that will save the world.
I’m gonna speak the words that will heal our souls.
I’m gonna light the fire that will burn away the darkness.
I’m gonna lead the march that will make us whole.”

‘Cause she was just a little girl,
Dreaming bigger than she knew she should.

Life, the Universe, and Everything

Math is everywhere, hidden in places where we don’t even expect to see it. For example, take a look at the following image:

Slide2

What do you see?

Most people say “music.” People who have studied the piano might recognize this as a piano score. And a true enthusiast might recognize it as the third movement of Beethoven’s Moonlight Sonata.

What you’ve probably never thought of before, though, is that a musical score is actually a form of graph. It tells the performer what combination of notes to play at a given moment in time. In other words, it shows sound as a function of time.

In the image below, I’ve added labeled axes to draw attention to this:moonlight_sonata_graph

Now consider a photograph. Below is one of the most spectacular images I found when Googling “photograph.” (Thanks to whoever posted it!) I love how it shows the strings of mucus frozen in time.

tiger_photo

Anyway, a photograph itself is also just a type of graph — and not just metaphorically. In fact, even the way images are produced in our brains is just a way of numerically graphing the intensity and frequency of light that falls on different portions of our retinas. In essence, your retina is the x-y plane and the light is the quantity being graphed.

Below is what the photograph looks like when graphed in three dimensions from different angles, with the colors changed to a different color scale:

tiger_photo_graphs_1

Now here is the same graph when viewed from directly above, so that the tiger is easier to make out:
tiger_photo_graphs_2

Here’s another example of a great photo:
frog_photo

And here it is with the same procedure applied to it. This one works a little better than the tiger because it isn’t filled with little white spots that end up looking like noisy spikes in the graph.frog_photo_graphs_1

Below is the graph when viewed from directly above, just as I did for the tiger. Pretty cool, huh?frog_photo_graphs_2

Now consider something that really seems to have nothing to do with math: a piece of literature. Below is the first paragraph from A Tale of Two Cities, by Charles Dickens.
Tale_of_2_cities

It, too, can be considered as a type of graph. It’s a graph that tells the reader what words to speak or think as a function of time:Tale_of_2_cities_graphThere are, of course, many other examples of graphs:

footballstragety

What I’m saying is that anything can be thought of as a kind of graph. Really, though, it’s not just graphs that are so powerful, but numbers themselves. This is because numbers encode information. For example, an entire song can be encoded in a single number. So can a photograph, or even a movie.

What’s particularly fascinating is that physicists now believe that physical reality itself is composed of information. In fact, the universe might even be digital. And since numbers encode information, it is possible that the entire universe could be represented by a single number.

Take a minute to meditate on that.

If that’s true, then there’s only one thing we can conclude…

No Height, No Depth — An Original Praise Song

Emerging from the tomb (inside view).

Click to hear the song on YouTube.

A few years ago, I wrote a very nice praise song (if I do say so myself), titled “No Height, No Depth.” It creates a rather neat bridge between the idea that we cannot escape from God’s penetrating understanding of our hearts (a terrifying prospect), as described in Psalm 139, and the promise that nothing can separate us from God’s love (a comforting thought), as stated in Romans 8:38-39.

I finally got around to creating a lead sheet for the song, and I’d like to share it here. Feel free to use it and distribute it as much as you like. Click on the image below to download it in PDF form:

Click to download the lead sheet for the song.

Click here (or on the picture at the top of this post) to see the music “video.” Just make sure you stick around long enough to hear the chorus! (It starts at about 1:05.) That’s the exciting part. (Actually, the part leading up to the chorus, around 0:55, is pretty cool too.)

I would be just tickled pink of someone else were to actually record this song, because I really think it has a lot of potential. As always, if you do so and post it on YouTube (and send me a link), I promise to send you a lollipop with my initials engraved on it.

Here are the lyrics in full:

No Height, No Depth

by Olen Rambow

You have searched me and you know me—when I sit and when I rise.
You discern my coming and going; you are familiar with my ways.
You perceive my thoughts from afar.
You alone truly know my heart.
Where can I go from your spirit?
Where can I flee from your presence?
Wherever I am, Lord, you are there.

No height, no depth, can separate me from your love, O Lord;
And neither life nor death can overcome the work of Christ in me.

Righteous king of all creation—God of glory, Lord on high,
You are blameless, pure, and holy; saints before you prostrate lie.
Who can enter into your presence?
With you, Lord, no wicked man can dwell.
I stand before your throne of judgment,
Deserving your wrath and condemnation.
I’m desperate for hope. Lord, make a way!

Now comes Christ, my intercessor. He has heard my anguished cry.
With full grace, he takes up my burdens, and with the Father’s will complies.
See him bear his cross up to Calvary.
See him beaten, stabbed, and crucified.
Into a tomb they sealed his body,
But on the third day, he rose in glory.
He conquered the grave and set me free.

No height, no depth, can separate me from your love, O Lord;
Neither life nor death can overcome the work of Christ in me.

I proclaim your victory.

Fat-Water Separation in MRI

A figure from Dixon's original paper on fat-water separation.

A figure from Dixon’s original paper on fat-water separation.

To anyone who is interested in fat-water separation within the field of MRI, I offer the following (click for PDF):

Fat-Water Separation

This is a chapter from my master’s thesis that explains the most common methods of fat-water separation and presents a very handy geometric interpretation of two-point Dixon imaging. I’ve been told that the interpretation is very helpful for newcomers to the field.

If you find it useful at all, please share it.

What is fat-water separation, you might ask?

Good question.

MRI detects hydrogen atoms; and there are two main places in your body where hydrogen atoms hang out: fat molecules and water molecules. So in the context of MRI, we can say that most tissue in your body is either fat or water. (Examples of “water” here include muscle, blood, skin, and pretty much anything except fat.) Fat-water separation is simply the process of distinguishing between the two tissue types in an MRI image.

Doctors often want either to remove the fat from an image so they can see things the fat might be hiding, or to create two separate images, one of fat only and one of water only. Doing so can help them give patients a more accurate diagnosis.

Fat-water separation techniques involve some interesting physics and math. For more info, click on the link provided above.

Introduction to MRI

homer

(Before you complain, see note at end of post.)

Back in 1997, at the end of my tenth grade year, my chemistry teacher explained the principles underlying magnetic resonance imaging. I’m sure it wasn’t a very in-depth explanation, but I still remember thinking, “Wow, that’s complicated. I’ll never understand it.”

Well, a lot has happened since then. I got a bachelor’s degree in physics and math. I worked as a teacher for seven years, five of which were spent in China. Then I went back to graduate school to get a master’s degree in applied physics.

The topic of my research? Magnetic resonance imaging.

As I began studying MRI in graduate school, I still worried that I might not be able to understand it. But I once again rediscovered a truth that I keep finding myself rediscovering: namely, that if you invest enough time and hard work in studying a topic, you’ll eventually get it, no matter how daunting it may at first seem.

In the end, I didn’t just learn the basics of MRI, but I published a thesis on my own contribution to the field: an improved method for distinguishing between fat-based and water-based tissue in magnetic resonance images.

If you’re curious about how MRI works, I offer you this (click the link to download the PDF):

Foundations of MRI

It’s a chapter from my thesis that explains the basic physics of MRI — from how the tissue in your body is magnetized when you are placed in a magnetic field, to how images are obtained with the desired contrast between different tissue types.

I hope you’ll find it to be puddles of fun. Please splash around to your heart’s content.

NOTE: Anyone familiar with medical imaging will immediately notice that the Homer Simpson image at the top of this post is not an MRI. But hey, it’s already a fictional image of a fictional character, and it’s really funny, so please give me a break.

BWYA Graduation Speech – May 2009

GradHat

In the spring of 2009, I had the honor of being asked to give the graduation speech at the Beijing World Youth Academy, where I taught physics from 2007 to 2009. It is (or was at the time) their tradition to ask one of the departing teachers to be the main speaker at the ceremony. They probably asked other people first, but no one else was willing, as we were all busy with our end-of-the-year insanity. And so they turned to me.

With my characteristic modesty, I declare that I did a pretty good job coming up with a simple and inspiring message. Here it is:

从2005年到2007年,我在中科院半导体所从事论文编辑和英语教学的职业。 在这期间,我为想要在国际期刊上发表论文的在校研究生们编辑过好几百篇的论文。 在我编辑这些论文的同时,我也记录下了母语为中文的人的论文中最常出现的英语语法错误。等到我结束在半导体所任教时,我根据这些观察和记录编写了一本书, 名为 Scientific Writing for Chinese Researchers.

写 完这本书的很长时间内,我都不太愿意在美国公开和出版这本书。因为我认为它只适合中国研究生。但是,最近我又重新读了一遍这本书,并在读过之后改变了我的 想法。其实书中有很多写作规则适合任何想要写论文的人。其中更适合中国学生的部分也会对在美国的中国留学生很有帮助。

Okay, now here’s everything in English:

From 2005 to 2007, I worked as an editor and English teacher at the Institute of Semiconductors, which is a branch of the Chinese Academy of Sciences in Beijing. During that time, I edited hundreds upon hundreds of papers that were written by Chinese graduate students who wanted to have their work published in international journals. As I corrected their writing, I kept track of the most common errors that native Chinese speakers make when they write in English, and at the end of my time there I compiled all of my observations into a book: Scientific Writing for Chinese Researchers.

For a long time, I was reluctant to share this with people in America because I felt that the book was only appropriate for graduate students in China. I recently went back and read through it, though, and I’ve changed my mind. Many of the principles are appropriate for anyone who wants to write a paper, and the parts that are specifically for Chinese students will probably be very useful to Chinese graduate students here in America.

The book is available here.

A Place in the Sky

When Robert Jordan, the author of the awesome Wheel of Time series, died of amyloidosis in 2007, some fans published a compilation of short stories to raise money for amyloidosis research. I wrote and submitted the following story, and it was included in the compilation:

Note: The war in which Denelain was wounded nine years ago was very different from the “Great War,” which was waged generations ago and involved the gods themselves. I think I need to edit the story a little to make that more clear.
