Chaos and cause
To fully appreciate what this means, heed a lesson from Fyodor Dostoyevsky’s great novel, The Brothers Karamazov (1880), which asks how a benevolent God could allow suffering. There is just one virtuous character in the novel, the monk Father Zosima, whose simple teaching, dictated through the genius of Dostoyevsky, sheds light on chaos, causation and difference-making:
See, here you have passed by a small child, passed by in anger, with a foul word, with a wrathful soul; you perhaps did not notice the child, but he saw you, and your unsightly and impious image has remained in his defenceless heart. You did not know it, but you may thereby have planted a bad seed in him, and it may grow, and all because you did not restrain yourself before the child, because you did not nurture in yourself a heedful, active love … for one ought to love not for a chance moment but for all time. Anyone, even a wicked man, can love by chance. My young brother asked forgiveness of the birds: it seems senseless, yet it is right, for all is like an ocean, all flows and connects; touch it in one place and it echoes at the other end of the world.

Since these AIs are just giant matrix multiplication machines, “intuition” now has a firm grounding in math - just much bigger, more complicated math than the usual kind that we call “logical”.
This would be a common pattern for sciences: much worse at everyday tasks than people who do them intuitively, until it generates some surprising and powerful new technology. Democritus figured out what matter was made of in 400 BC, and it didn’t help a single person do a single useful thing with matter for the next 2000 years of followup research, and then you got the atomic bomb (I may be skipping over all of chemistry, sorry).
– What Are We Arguing About When We Argue About Rationality?
What he seeks to practice is, in a phrase popularized by the Marxist philosopher Antonio Gramsci, “pessimism of the intellect, optimism of the will.”
– Can Science Fiction Wake Us Up to Our Climate Reality?
Caulfield then introduced two different ways of thinking about how we engage with ideas when we’re on the internet: The web as a garden and the web as a stream. Think of the web as an organically developing garden: a space in which there’s no predetermined order or relationship of things to one another. Caulfield writes, “Every walk through the garden creates new paths, new meanings.” What came first in the garden doesn’t matter either. Each thing in the garden is related to the other things as it exists in the moment.

Humility, by contrast, admits that defeat is possible. It occupies the nebulous zone between preparedness and precaution by asking a moral question: not what we can achieve with what we have, but how we should act given that we cannot know the full consequences of our actions.
– “Preparedness” Won’t Stop the Next Pandemic
Rather than trying to beat the coronavirus one booster at a time, the country needs to do what it has always needed to do—build systems and enact policies that protect the health of entire communities, especially the most vulnerable ones. Individualism couldn’t beat Delta, it won’t beat Omicron, and it won’t beat the rest of the Greek alphabet to come. Self-interest is self-defeating, and as long as its hosts ignore that lesson, the virus will keep teaching it.
– Ed Yong | America Is Not Ready for Omicron
For instance, in Plato’s Euthyphro dialogue, Socrates runs into the local priest and expert on the gods, the self-same Euthyphro, who plans to do something unholy by the local standards – to press charges against his own father. Socrates asks how he, a man wise in the ways of the gods, could do something the gods would obviously condemn?
Euthyphro answers that, in fact, his plan passes the gods’ standards. This raises only more questions for Socrates, who presses on and asks Euthyphro to clarify what he means by holiness. If Euthyphro’s plan is so holy, surely he could explain his reasoning and spell out the nature of holiness? Under questioning, though, Euthyphro reasons himself into a corner, unable to give a clear account of holiness. The dialogue ends there, with the premier theologian of Athens excusing himself with a version of ‘I’m actually late for a thing.’
– How do you know?
Researchers from Harvard and the University of Virginia brought subjects into a lab where they had to choose between two torture devices. The first option was to push a button that would deliver a safe, but still sharply unpleasant, electric shock to themselves. Two-thirds of the men in the study chose to shock themselves despite the fact that they’d 1.) all been shocked in an earlier phase of the study, and 2.) all professed that they would pay money to avoid the unpleasant experience in the future.

Sigmund Freud once stated that no one believes in their own death. In the unconscious, there is a blank space where knowledge of this one sure thing about our futures should be.

You’ve probably heard the probabilistic (aka Bayesian) side of things before. Instead of thinking “I’m sure global warming is fake!”, try to think in terms of probabilities (“I think there’s a 90% chance global warming is fake.”) Instead of thinking in terms of changing your mind (“Should I surrender my belief, and switch to my enemy’s belief that global warming is true”), think in terms of updating your probabilities (“Now I’m only 70% sure that global warming is fake”). This mindset makes it easier to remember that it’s not a question of winning or losing, but a question of being as accurate as possible. Someone who updates from 90% to 70% is no more or less wrong or embarrassing than someone who updates from 60% to 40%.
– Scott Alexander
Pundits have urged people to “listen to the science,” as if “the science” is a tome of facts and not an amorphous, dynamic entity, born from the collective minds of thousands of individual people who argue and disagree about data that can be interpreted in a range of ways.

In other words, “vibes” are similar to the approximations that machine learning systems use, and the two feed off of each other synergistically. The situation is precisely encapsulated by Goodhart’s Law: “When a measure becomes a target, it ceases to be a good measure.”

the black mountain rises, a reference point
to every human moment, utterly silent.
No one climbs this mountain, there are no trails,
because the place is holy: it does not exist to serve us,
it is not meant to please us, it simply is,
and in this way it is a god.
Mountains do not move, and that is their mountainness.

“For it must be understood that this is a children’s book only in the sense that the first of many readings can be undertaken in the nursery. Alice is read gravely by children and with laughter by grown ups; The Hobbit, on the other hand, will be funnier to its youngest readers, and only years later, at a tenth or a twentieth reading, will they begin to realise what deft scholarship and profound reflection have gone to make everything in it so ripe, so friendly, and in its own way so true. Prediction is dangerous: but The Hobbit may well prove a classic.”
– C.S. Lewis reviewing The Hobbit, The Times Literary Supplement, October 2, 1937
Is a flower beautiful?
Is a fruit perhaps beautiful?
No: they merely have color and form
And existence.
Beauty is the name given to something that does not exist
The name I give to things in exchange for the pleasure they give me.
It means nothing.
So why do I say of things: “They’re beautiful”?

On The Plague
Published:
In the beginning of the pandemic, commentaries on Albert Camus’ The Plague (1947) mushroomed and the book sale went up, for obvious reasons. I, too, joined this train, reserving the book from the library. In a somewhat ironic meta-allegory of the pandemic though, I read it halfway, and due to no loan extension because somebody else reserved it, gave up on it. Don’t my languid lockdown reading pace, and the helplessness of it, reflect the general gloomy pandemic mood, a little bit?
It is Wednesday
Published:
The sky cried her heart out
tempestuously on Monday
On Tuesday morning
the tears kept falling
percolating the slumbered
It has slowed to rare droplets now
But I wonder:
with your grey countenance
Do you still have more
sadness to pour out?
It is a gloomy day. The new COVID-19 cases today in the world is 208k, more than 1/4 of which are from Indonesia. Singapore experienced a steep surge after a lull as well.
Here is another verse of consolation (source):
Do not stand
By my grave, and weep.
I am not there,
I do not sleep—
I am the thousand winds that blow
I am the diamond glints in snow
I am the sunlight on ripened grain,
I am the gentle, autumn rain.
As you awake with morning’s hush,
I am the swift, up-flinging rush
Of quiet birds in circling flight,
I am the day transcending night.
Do not stand
By my grave, and cry—
I am not there,
I did not die.
Man Arai, a Japanese composer, set a melody to this verse, and here are some other sung versions:
By Hayley Westenra in English
By Paul Kim in Korean. The Korean version was also often sung as a tribute of the 2014 Sewol ferry accident.

Thaxted
Published:
I first heard the hymnal tune Thaxted in Corrinne May’s The answer. Her lyrics is a simple psalmic consolation, and paired with the simple tune, it proves to be indelible. The Methodist church I was worshipping at had it sung in the service a number of times.
‘This is not a post’ post
Published:
Magritte’s “This is not a pipe” painting is one of Douglas Hofstadter’s obsessions in Gödel, Escher, Bach: An Eternal Golden Braid. It may be a Treachery of images like the title suggests, but it is also about the treachery of language, the self-referential nature that Hofstadter calls ‘a strange loop’. For example, the famous “This sentence is not true”, a variant of liar’s paradox. If the statement is true, then it’s “not true”. If the statement is false, then it’s negated so that the falsity is “not true”. It is something that continues to endlessly boggle the mind. One might think it is a philosopher’s fancy – that, it may be – but consider that Gödel’s incompleteness theorems need that self-reference as a foundation. I concede that it is not something that may affect our daily lives, but, you know, it can make one ponder about computability, the nature of consciousness, and stuff.
Now, I have observed this self-reference in some objects, though I don’t suppose the manufacturers have the nature of consciousness in mind. Behold, the “this is not a safety barrier” safety barricade and the “this is not a lifesaving device” kickboard. You can see that these two things do not have identity crises: it’s actually the very opposite; ‘they’ are certainly sure about their functions. The safety barricade: I can function as a safety barrier, but not 100% of the time. Similarly, the kickboard: I can function as a lifesaving device, but not 100% of the time. You can almost hear the echoes of the underlying subtext (so don’t sue me), can’t you?
You can ponder this more while looking at my terrible drawing:
NB: I found it highly amusing that the safety barricade is embossed/printed/stenciled/stickered with “This is not a safety barrier”, but spray-painted with “SB”. That is one way to solve the linguistic and legalistic quandary I suppose: “It’s not a safety barrier; it is just, you know, SB”.

In my work as a mediator, I’ve learnt that successful conversations always involve what I call a ‘gem statement’. When two parties have listened long and hard to each other – have made the heroic effort to listen curiously and empathically even when they disagree strenuously – someone eventually unearths a glowing, priceless gem. It usually takes the form of a short, powerful statement –How to have a difficult conversation

On efficacy
Published:
The term efficacy is not new for the drug industry people, but of course it has now entered the public consciousness thanks to the vaccine efforts. As Carl Zimmer pointed out, our intuitive understanding of “95% effectiveness” is that 95 out of 100 people who get the vaccine will be immune.
As you might already know, it’s not exactly that. That number means that out of certain number of symptomatic, PCR-positive participants, the placebo arm has 95% more than the vaccinated arm, where vaccine:placebo population is 1:1. Taking the numbers from the NY Times article, Pfizer waited until they had 170 cases (for statistical power): 162 in placebo, 8 in vaccine. If vaccine:placebo populations are exactly 1:1, the denominators all cancel out and efficacy = (162-8)/162 = 95%. Even if it is not exactly 1:1, usually it is close to that, so this is a good shortcut for quick calculation. For exact figure, just replace the absolute numbers as fraction in that arm instead – see how the denominators cancel out when a=b :
So, efficacy is a proxy for the eventual effectiveness. The former is in controlled clinical trial setting, while the latter is in messy real word setting. Some points on why there will be discrepancy between the 2:
- Clinical trial population is biased – only certain kind of people would volunteer for the trial. You can expect that they usually are healthy and do not have underlying conditions. Behaviour-wise, they would tend to be more cautious as well.
- Blinding is imperfect. Some people get mild reactions from the vaccine, which sort of tell you that you are in the vaccine arm.
- Asymptomatic cases are not accounted for. The participants are not tested regularly. Instead, they are only tested when they self-report symptoms. This is the case for Moderna trials. AZ-Oxford does weekly swabs so they have data about asymptomatic cases as well.
Markov state models
Published:
I’m trying to learn Markov state models for my MD analysis. I will put thoughts and notes here.
- There are 2 popular Python modules, PyEMMA and MSMbuilder. I’m sticking to PyEMMA at the moment because I had trouble installing the other

- PyEMMA Jupyter notebook tutorials
- Usually my eyes glaze over at statistical mechanics maths, but the PyEMMA paper is surprisingly very readable and easy to follow

Why academia shouldn’t be a competition
No idea how to summarise this. I feel encouraged, I guess? This touches on some soft aspects of being an academic that I’m not used to evaluate for myself. I think one takeaway is the perennial metric-ising everything problem. On one hand, translating human beings into numbers is a sort of reductionism, but on the other, how else one is supposed to do evaluations and comparisons? Stuff that comes to mind and some that was brought up: IQ, uni ranking, being a good mentor, not being toxic, being a good colleague.
Computational chemists in relation to experimental ones
Published:
Here is a paper buried in my reading backlog, and I am pleasantly surprised that it has useful insights particularly for me.
Even though what the authors talk about is computational chemists and medicinal chemists in pharma research setting, I still learn some stuff applicable to my own role as computational chemists collaborating with experimental biologists mosts of the time. With the advent of AI, the authors then argue that the old dynamic must change.
There is a need for computational chemists to well delineate the limits of their techniques and set expectations reasonably and equally for medicinal chemists to both appreciate the bounds of what is on offer and also recognize that an equivalent evaluation of their own “hunches and predictions” might not perform any better.

I am excited to learn that Sir Paul Nurse has an upcoming book attempting to discuss this perennial question. The title is of course an homage to Schrödinger’s earlier treatise with the same title. I read that quite a while ago, and what was quite amazing was that it was written before the structure of DNA was known. I recall that I had attended a doctoral course with the same title as well. And the content was as broad as it suggests: the course coordinator invited outside speakers for talks, and often the talks were beyond mere biology, so it was a very interesting, thought-expanding, course.
The subtitle “Understanding biology in five steps” gives the central thesis: cells, genes, evolution, life as chemistry, life as information system. Information system is of course a very curious metaphor. Schrödinger was in the era of early computing – how does our understanding of life now look like when examined in parallel to modern computing?
Nurse has a 1-hour talk, which I watched with interest, so I am looking forward to read the book.
Defining energy
Published:
“How do you define energy?” is a question that would stump me. High school physics does not give satisfactory answer; it just gives the formula straight away. We know that it has to be of certain unit; and it fits the physics equations like such and such. Today I learned the more rigorous definition from Sabine Hossenfelder’s explainer video, but nagging me still, what is it, epistemologically?
I remember the first time I came to a similar reckoning was in chemistry lessons about electron orbitals. I was like “Huh these things are so weird how come they are like that?” and our chemistry teacher Mr A, who has philosophical penchant, just shrugged with an enigmatic smile, “That’s just what we observe them to be. These mathematical functions fit the observation.” Insert brain expansion meme here.
I have since seen many baffling things alike, especially in biology. We scientists keep pounding away at the what, what, what questions. Do we ask how and why enough? Should we? Should we not, because they are too difficult?

It’s as bad as cell culture or X-ray crystal growing, two other areas that are famously infested with evil spirits and voodoo rituals. You run into these systems that are just intrinsically very sensitive to initial conditions, with variables that are sometimes too small or obscure for you to even realize that they’re variables.

Conditional execution in bash
Published:
Situation: You want to execute a script as soon as a particular file is created.
This is an easy one-liner:
# waiter.sh
# Usage: ./waiter.sh script_to_be_run file_to_anticipate [time_delay, def. 10 mins]
while [ ! -f $2 ]; do sleep ${3-10m}; done; bash $1
The while loop keeps checking the existence of the specified file: while the file does not exist the loop will run sleep on and on. When the file exist, loop will be exited and the specified script will be run. Could it get any simpler? It seems like a waste just to continually check, but I don’t see a better option for now. (If you are wu liao run bash -x waiter.sh to see how many sleeps your waiter.sh has to go through to finally run your desired script.)
One learning point – I was using this kind of thing before to make a positional argument optional:
[ "$3" = "" ] && time_delay="15m" || time_delay=$3
This is a “ternary” bash construction, which you can construe as a shorthand conditional: A && B || C means “if A is true; execute B; else execute C”.
Turns out the easier way is using shell parameter expansion magic:
time_delay=${3-15m} # if $3 is unset, set $3 to 15m
time_delay=${3:-15m} # if $3 is unset or null, set $3 to 15m

Choosing our religion
Creation is thus seen as a relationship of radical dependence. To cite an insight deriving from St Thomas Aquinas, God’s creation of the world should not be likened to a carpenter making a chest. A better analogy would be more intimate – a singer producing a song, for instance. The difference is profound. Carpenter and chest are discrete entities. Carpenters can pass on the articles they make, never seeing them again. But a song is by definition an emanation of a singer.
A crucial difference between humans and other animals is equally plain. Genuinely fulfilled human lives involve further dimensions including dignity, which is connected with the exercise of choice; and virtue, implying the need to stretch or transcend ourselves. G. K. Chesterton wrote that it makes little sense to upbraid a lion for not being properly lion-like: lions are lions. The same is not true of human beings. People everywhere have a striking idea that they ought to behave in certain “humane” ways, but also an awareness that they do not in fact behave as they should. It is often noted that these two facts are the root of all clear thinking about ourselves and our world.

With cultural evolution, we should use our unique gifts of language and art and science to understand each other, and finally achieve a human society that is manageable if not always peaceful, with wildlife that is endlessly creative if not always permanent.

Nature | Extreme chemistry: experiments at the edge of the periodic table
This is somewhat as expected: the strength of chemical bonding tends to decrease down a periodic group, as atoms get larger. But to fully explain superheavies’ chemistry, Pershina’s calculations must also take into account relativistic effects. In very heavy atoms, which have super-strong interactions between the innermost electrons and the highly charged nuclei, the electrons are travelling so fast (potentially at more than 80% of the speed of light) that their mass increases, as special relativity predicts. This pulls them farther in towards the nucleus, which can mean that they screen the outer electrons from the nuclear charge more effectively. That alters the outer electrons’ energies and, consequently, their chemical reactivity.

The stuff Snow was talking about in this lecture feels antiquated now. Probably it was the peculiar time and place that polarised the “two cultures”. Or perhaps it was Snow’s caricaturisation. (Snow himself looked retrospectively at his 1959 lecture in Part II.)
Nevertheless we can always learn something – some of the points are interesting and and applicable. The divide of the current age though is between scientists and non-scientists – hopefully it is something we will overcome. The introduction by Stefan Collini also proves to be a commentary that is also worth reading.

I have been teaching swimming to a friend who is relatively a beginner. I often found myself having no words to describe a certain motion or posture and go “you just have to experience it with your body”. While I do attribute this partly to my lack of training as a swimming instructor, I still think there are things that cannot be conveyed in words, especially when it comes to motoric stuff, don’t you think?
Martial art: Definitely a motoric stuff
Image credit: SMBC Comics
Anyway, thinking about this my mind wandered to the talk about failures in science. It’s like this – before I did my PhD I have of course heard things about the inevitable stress and failures (and I find myself saying the same thing to pre- and current PhD students too) but knowing it cognitively is different from experiencing it oneself, isn’t it?
Here is a recent Nature article on the subject: <Scientific progress is built on failure>. Reading this, on one hand I hope that a PhD student or a prospective one takes note and does the necessary mental preparation; but on the other hand, I cannot help but go “My son, I know these things would fall on deaf ears. You just have to experience it for yourself”.

I will illustrate some good practices of writing bash scripts by showing you how I write and refactor my bash script dock.sh that does some preparation for docking and then launch docking.
Revisiting Gödel
Published:
For years after I first encountered Gödel’s incompleteness theorems, they had utterly baffled me (just look at the Wikipedia page and tell me if it is comprehensible). So I dismissed it as one of those inexplicable-to-non-mathematicians things.
Rainbow connection
Published:
My most impressionable memory of seeing a rainbow happened in a tourist bus in Iceland. It was faint, like a watercolour painting on the canvas that was the pale blue sky and the treeless Icelandic landscape. I noticed it first, and a few minutes later the whole bus was teetering at one side of the bus, peering spellbound out of the window (except for the bus driver, I hope).
