Doctors seem to diagnose what they know, so find out what they know before you ask them whats wrong with you.

At a lecture following the publication of his book, Sustainable Energy – Without the Hot Air, he was assailed by an angry environmentalist who asked him why he was “so hostile” to wind power. [Prof David] MacKay smiled sweetly and replied: “I’m not hostile to anything. I’m just in favour of arithmetic.”

Two nice turns of phrase with a pertinence far and wide.

“I miss the 1990’s sometimes. People had no expectations, and so they thought bigger.”

“books of the type written by the current hotshot Op-Ed writer at the New York Times may get some hype at publication time, manufactured or spontaneous, but their five year survival is generally inferior to that of pancreatic cancer.”

“This may upset some of my students at MIT, but one of my concerns is that it’s been a predominantly male gang of kids, mostly white, who are building the core computer science around AI, and they’re more comfortable talking to computers than to human beings. A lot of them feel that if they could just make that science-fiction, generalized AI, we wouldn’t have to worry about all the messy stuff like politics and society. They think machines will just figure it all out for us.”

“Throughout her career, Gonzalez has done “a bit of everything” at LIGO, she says. For a while, she took on the crucial task of diagnosing the performance of the interferometers to make sure that they achieved unparalleled sensitivity — which is now enough to detect length changes in the 4-kilometre-long arms of the interferometers to within one part in 1021, roughly equivalent to the width of DNA compared with the orbit of Saturn. “

2017: the importance of being harmless and irrelevant

Geoffrey Boulton (University of Edinburgh) in, “What are Universities for?”

A university that moulds itself only to present demands is one that is not listening to its historians. Today’s preoccupations are inevitably myopic, often ephemeral, giving little thought for tomorrow. History is at its most illuminating when written with the full consciousness of what people wrongly expected to happen. Even in the domain of technology, future developments only a few years away have been shrouded from contemporary eyes. Many, possibly most, have arisen unexpectedly from research with other objectives, and assessments of technological potential have invariably missed the mark.

Thirty years ago, scientists who studied climate change, and I am one of them, tended to have long hair and very colourful socks. We were regarded as harmless but irrelevant. But the serendipitous investment in their work revealed processes that we now recognise as threatening the future of human society, and the successors to those scientists are playing a crucial role in assessing how we need to adapt.

A sensible way to start the year.

“I think the dilemma Brexit poses for Scotland is pretty intolerable,” he says. “If Scotland has to clean out all its universities of European citizens there are really horrible things that are going to happen.”

There are lots of downsides to technology making it harder for some things to be forgotten. But lots of advantages too. I use a simple diarying App that is available on mobile and Mac, Day One.

One of its nice features is that gives you the option to see comments you have made on the same date in previous years. Now, like many people I tend to often agree with myself — at least over the short term— but it is fun to read earlier musings and wonder if the nuance needs changing, but also to see the same underlying memes appearing again and again. Often, I am still in agreement, with my earlier comments. Sometimes not. Here is one from three years ago.

“It is a variant of the (at present unfashionable) historical method. It consists, simply, in trying to find out what other people have thought and said about the problem in hand: why they had to face it: how they formulated it: how they tried to solve it. This seems to me important because it is part of the general method of rational discussion. If we ignore what other people are thinking, or have thought in the past, then rational discussion must come to an end, though each of us may go on happily talking to himself.” from “The Logic of Scientific Discovery (Routledge Classics)” by Karl Popper

“Imagine if we taught baseball the way we teach science. Until they were twelve, children would read about baseball technique and history, and occasionally hear inspirational stories of the great baseball players. They would fill out quizzes about baseball rules. College undergraduates might be allowed, under strict supervision, to reproduce famous historic baseball plays. But only in the second or third year of graduate school, would they, at last, actually get to play a game. If we taught baseball this way, we might expect about the same degree of success in the Little League World Series that we currently see in our children’s science scores.”

‘People pay a lot for a great education now, but you can become expert level on most things by looking at your phone.’

Sam Altman quoted in the New Yorker

It is just nice to see it in black and white. So simple. BTW, the quote came via the wiser (not ‘smarter’) Nick Carr, who commented: ‘By “a really good life,” Altman means a virtual reality headset and an opioid prescription’.

“The immune system is unknowable, dynamic, complicated, and it always surprises you.” Stephen Deeks quoted in Science. And yet, useful discoveries are made, and have been made for a long time.

Failing again. Improved possibilities.

I have always thought two Irish writers great guides to life: Samuel Becket, and Brian O’Nolan (aka Brian Ó Nualláin, Flann O’Brien, Myles na gCopaleen ). Becket’s line, in a postcard of the lithograph by Tom Phillips of him, hangs on my wall: “No matter. Try again. Fail again. Fail better.” But now I have come across something more fitting for my state, and with optimism:

“I work on, with failing mind, in other words, improved possibilities.”

Review of The Letters of Samuel Beckett, Volume IV, in the FT.

‘Innovative’ educational practice is more fashion-driven than those who attend the catwalks are.

The NHS could then become a threadbare charity, available to avoid the embarrassment of visible untreated illness. Julian Tudor Hart  BMJ 2016:354;i4934

Use of the term world-class. Usually means one of the following: you are lazy, corrupt, or deluded. Rarely, it means something else that in almost all instances does not need saying. 

“Physicists studying sport have established that many fieldsmen are very good at catching balls, but bad at answering the question: “Where in the park will the ball land?” Good players don’t forecast the future, but adapt to it. That is the origin of the saying “keep your eye on the ball”.
As complex systems go, the interaction between the ball in flight and the moving fieldsman is still relatively simple. In principle, most of the knowledge needed to compute trajectories and devise an optimal strategy is available: we just don’t have the instruments or the time for analysis and computation. More often, the relevant information is not even potentially knowable. The skill of the sports player is not the result of superior knowledge of the future, but of an ability to employ and execute good strategies for making decisions in a complex and changing world. The same qualities are characteristic of the successful executive. Managers who know the future are more often dangerous fools than great visionaries.”

I think you could say the same about education and medicine: you can say less than you know.

A sceptic’s weekend read

A nice dose of uncommon  common sense:

“The world of learning is a failure factory, not in the positive sense of learning from failure, second chances and progress but one of selection, road blocks, disappointment, discouragement and real failure. As professionals, we seem to have lost our critical faculties, stuck in a time warp of old theory and models that were never verified in the first place; lectures, hands-up anyone, MaslowMyers-BriggsLearning StylesPiagetNLP, Kirkpatrick. This is not good enough. It introduces certainty where there is nothing but ideological belief and unverified theory and practice. We need to think critically and see failure as part of what it is to learn.”

Donald Clark Plan B

“It’s no accident that only 11% of the US workforce is passionate about their work. This is a sign of great success. This is exactly what these institutions were designed to do – suppress passion. It starts with our schools that seek to prepare us for all the other institutional environments seeking people who can reliably follow instructions and execute in a predictable manner. Think of our current institutions as powerful chisels, relentlessly chipping away at our edges until we fit neatly into the tightly defined roles that our institutions have create.
