We’re really, really trying to avoid new WitCHes right now, but people keep throwing them at us. This one comes courtesy of Simon the Likeable, who suggested we watch the following, and who will pay dearly for it.
Commenter has SRK has flagged a related video (and will pay dearly for it):
an open letter attacking the attackers of “cancel culture”;
[Space kept blank for the next iteration].
There are plenty of left-wing thugs pretending that “cancel culture” is a fraud, and there are plenty of right-wing thugs pretending that they and their thuggish cronies don’t play the same nasty sport. For us, the smartest takes are:
But, really, “cancel culture” is what we gotta solve right now? One would think that being inundated with plague, and having the World heating to the point of no return, and with the three superpowers being led by homicidal maniacs, that would be plenty enough on our to-do list. But, if taking hair-trigger offense and being a Blockleiter is your thing then, sure, go ahead and have fun.
In 1973, the BBC televised The Ascent of Man, the brilliant series by Jacob Bronowski on the development of science and society. In his final episode, The Long Childhood, Bronowski sums up what he regards as special to being human, and the essence of a healthy scientific society:
If we are anything, we must be a democracy of the intellect. We must not perish by the distance between people and government, people and power, by which Babylon, and Egypt, and Rome failed. And that distance can only be … conflated, can only be closed, if knowledge sits here, and not up there.
That seems a hard lesson. After all, this is a world run by specialists. Isn’t that what we mean by a scientific society? No, it isn’t. A scientific society is one in which specialists can indeed do the things like making the electric light work. But it’s you, it’s I, who have to know how nature works, how electricity is one of her expressions, in the light, and in my brain.
And we are really here on a wonderful threshold of knowledge. The ascent of man is always teetering in the balance. There’s always a sense of uncertainty as to whether, when man lifts his foot for the next step, it’s really going to come down ahead. And what is ahead of us? At last, the bringing together of all that we’ve learnt in physics and in biology, towards an understanding of where we have come, what man is.
Knowledge is not a loose-leaf notebook of facts. Above all, it is a responsibility for the integrity of what we are, above all, of what we are as ethical creatures. You can’t possibly maintain that if you let other people run the world for you, while you yourself continue to live … out of a ragbag of morals that come from past beliefs. That’s really crucial today. You see, it’s pointless to advise people to learn differential equations, “You must do a course in electronics or in computer programming.” Of course not. And yet, fifty years from now, if an understanding of man’s origins, his evolution, his history, his progress, is not the commonplace of the schoolbooks, we shall not exist.
Bronowski spoke those words forty-seven years ago. Three more years.

This one was brought to our attention by the Evil Mathologre. It is a tricky one, since it involves the work of a school student, and the student is in no way a target for our criticism. Out of such concerns, we haven’t made this post a WitCH; it should be considered in the same vein as this Maths Masters column.
“… we had to investigate an element of the golden ratio in the built or natural environment so I decided to look at atomic structure …“.
Hugo considered the atomic mass number A (protons plus neutrons) of nuclides (isotopes), comparing A to the number N of neutrons and the number Z of protons. Of course, A = N + Z. Hugo then looked for “fibonacci nuclides”, nuclides for which the ratios A/N and N/Z are very good approximations to the golden ratio. He found a bunch, and suggested his results as a guide to hunting for new elements and nuclides. Hugo’s graphic above is a good illustrative summary of his investigation; the horizontal axis is N, the vertical axis is Z, and the black line indicates known stable nuclides.
OK, no big deal. From our perspective, having a class sent off to hunt for the golden ratio is asking for trouble, but it’s just an IA, and Hugo’s work seems interestingly exploratory-ish, in the manner the IB foolishly demands. But why did Hugo make the news, and what’s the problem?
Today, the Australian government released COVIDSafe, the Government’s coronavirus tracking app, based on Singapore’s TraceTogether version. The release comes complete with the Government’s predictable reassuring and cajoling and guilt-tripping. Should Australians trust them and use the app? Really? For us, there is a very simple answer: when and only when Vanessa Teague gives the all clear.
Vanessa is an expert on cryptography and, as it happens, is an ex-student and a good friend. She is very smart and is as principled a person as we have ever met. Along with many of her colleagues, Vanessa has been critical of the Government’s needless (and entirely predictable) secrecy over COVIDSafe. She has written a series of blogposts about their underlying concerns, and in particular the Government’s failure to follow up on promises and release COVIDSafe’s source code. This is Vanessa’s current stance on using the app (as of 23/04):
“In its TraceTogether form, I would be happy to run it on the train but refuse to run it in my home or office. I need to see the details of Australia’s version before I decide.”
And, if that’s what Vanessa suggests then that’s what we’ll do, right up until Vanessa and her colleagues suggest otherwise. We’ll regularly be checking on Vanessa’s blog and twitter account.
Postscript: We had planned on writing about Vanessa a month or so ago, when she made the news. That story is highly relevant, since it involves privacy concerns, government screw-up, an arrogant and inept minister, a limp lettuce watchdog, a thuggish department secretary being matey matey with a vice chancellor, and a spineless university. Yep, same old, same old. But, given the speed of the times, we’ll probably have to leave that story be.
The Minister for Health has today made an undertaking to release the source code “within two weeks”. We’ll see. (The formal agency response on privacy (26/4) states that such release will be “subject to consultation with the Australian Signals Directorate’s Australian Cyber Security Centre”.)
Vanessa and her colleagues have a new blog post (27/4). The post has been written “on a best-effort basis using decompiled code from the app, without access to server-side code or technical documentation.” Their conclusion:
Like TraceTogether, there are still serious privacy problems if we consider the central authority to be an adversary. That authority, whether Amazon, the Australian government or whoever accesses the server, can
recognise all your encryptedIDs if they are heard on Bluetooth devices as you go,
recognise them on your phone if it acquires it, and
learn your contacts if you test positive.
We’re not going to bother with the nasty guilt-tripping on the COVIDSafe app, including from numerous media nitwits who should know better. This from Bernard Keane suffices.
Vanessa now has a very good twitter thread on the seemingly contradictory safe/not-safe messages from IT folk.
UPDATE (11/5) Vanessa has a twitter thread (08/05) on ScoMoFo’s latest round of silly buggers.
I have no idea who Pueyo is, I cannot vouch for his data, and commenters are free to argue against his analysis and his conclusions. I do not claim to know what Pueyo’s analysis might imply for how any particular city or country should be responding at any particular time.
I’m not sure where this post, or this blog, might go for the next while. Nothing is as important to society right now as managing COVID-19. Ironically, I’ll probably have plenty of time sitting at home in the next weeks or months, to write on the standard maths ed topics.
I plan to update this post from time to time, with links to articles and reports that, to my amateur eye, seem considered and important. In general the articles will be linked without comment; linking them means I believe they are worth reading, but I am not pretending to be an expert and I am open to counterclaim on anything. Commenters are also welcome to suggest articles; I may then update the post with a link up high. My general intention, however, is to have fewer articles, of high quality.
To be clear, this post is not particularly intended to be a forum for naive mathematical models, and I don’t intend to engage in that. I’ll also try to lay off the snarkiness, at least in the actual post. Commenters can comment as they wish. If, for example, some Liberal clown or some Greens clown says something stupid on social media, feel free to call it out. But the post itself is intended to promote clear-headed analyses. My other posts will continue to be as charmingly snarky as ever.
