1: “The reason for the bite is crystal clear: it’s there for scale, so that a small Apple logo still looks like an apple and not a cherry.”

2: How Germany’s contact tracing system for covid-19 works.

3: Economic downturns tend to reduce gender inequality, but the one associated with covid-19 has disproportionately affected women.

4: There are four national anthems without lyrics.

5: Over the last month, I’ve received 3,100 work emails.

6: I heard on the radio this morning that Romans painted eyes on their ships because they believe the gods would protect ships with eyes on them. And it made me think: was this the real reason? Will people in two millennia look back at our time and say that we printed crossed-fingers on all lottery tickets because we believed it brought luck (as opposed to it just being a brand)? There are so many things in life which start as superstition but become traditions which are completely divorced from the original beliefs.

7: The Normal People TV series was better than the book. I know people say you can’t compare the two, but I’m doing it anyway.

8: A loose lock meant that I got to peek through a crack in the door into the southwest tower of the Tyne Bridge:

9: Balancing rocks really seems to have become a trend these days. I know this makes me sound grumpy, but I’m not really a fan: there’s something that feels entitled about taking a shared area of natural landscape and putting a personal ‘project’ on it rather than leaving it how it was found.

10: Citizens of Monaco are called Monegasques.

11: “Uncertainty is a natural state for clinicians and scientists; a reality that politicians seem unable and unwilling to grasp. This contrast plays out sharply when politicians claim to be ‘following the evidence’ in their response to covid-19. How can the evidence be so certain that it should be followed? Isn’t it better to accept uncertainty, communicate that uncertainty clearly to the public, but provide a convincing rationale for policy informed by, not following, the best available science and evidence?”

12: When I’m asked to give talks about antimicrobial resistance, I sometimes mention the issue of incorporating antibiotics into ships’ paint to prevent the formation of a biofilm on the hull which allows barnacles to attach. This initially seems like a ridiculous use of a precious resource, but the issue is actually a bit more subtle than it first appears: barnacles create surprisingly high levels of drag, increasing fuel consumption and carbon dioxide emissions from the ship far more than you might first imagine. I was therefore delighted to learn of the invention of HullSkater, which is basically Roomba for ship hulls.

13: What’s the difference between music and language?

14: “As disaster strikes, ‘baseball caps appear atop politicians’ heads like mushrooms after a rain,’ Jerry Ianelli wrote, in 2017, for Miami New Times. Ianelli called the disaster hat ‘performative folksiness.'”

15: I missed the news a couple of months ago that Renzi Piano’s replacement for the Ponte Morandi in Genoa has been structurally completed, less than two years after the shocking and tragic collapse.

16: It seems that Instagram’s artificial intelligence can’t reliably distinguish photos of naked people from photos of paintings or statues, even when backed up by 15,000 human reviewers. This is a bit of social media controversy which has been around for years, but has hitherto completely passed me by.

17: Solar panels in space generate more energy than those on Earth because our atmosphere reflects or absorbs over half of the solar energy reaching the planet. This topic popped into my head for no clear reason this morning, and the magic of the internet meant that clarification was only a click away. What a time we live in.

18: “The painful conclusion is that Britain has the wrong sort of government for a pandemic—and, in Boris Johnson, the wrong sort of prime minister. Elected in December with the slogan of “Get Brexit Done”, he did not pay covid-19 enough attention. Ministers were chosen on ideological grounds; talented candidates with the wrong views were left out in the cold. Mr Johnson got the top job because he is a brilliant campaigner and a charismatic entertainer with whom the Conservative Party fell in love. Beating the coronavirus calls for attention to detail, consistency and implementation, but they are not his forte.”

19: The OED defines “suspend” as “to debar temporarily from participation in something.” Today, I’ve seen the BBC using the construction “permanently suspended” for the first time, which seems like a significant moment of change in the use of that word.

20: Food is all about salt, fat, acid, heat… and Samin Nosrat, who is impossibly endearing.

21: “You often cannot innovate before the world is ready.”

22: Grief and paperwork come as a package in the US healthcare system.

23: “My experience of being a person is a continual act of becoming, of creation. If nothing else, you continually have to be another day older. To instead focus on the things that are never going to change—from the day that you are born—is like locking yourself in a room.” That struck a chord with me, which was an interesting and arresting experience because it was said by Lionel Shriver, whose opinions are usually diametrically opposed to my own.

24: What advice on covid-19 social distancing can be given to sex workers?

25: The last episode of The Good Place is almost as good as the last episode of Six Feet Under.

26: “In what may be the first known case of its kind, a faulty facial recognition match led to a Michigan man’s arrest for a crime he did not commit.”

27: Beautifully scented designer alcohol hand gel is a mainstream thing now.

28: This profile of Richard Horton gave me some new insight into his response to covid-19.

29: Midwifery is marginalised in the USA.

30: Fukushima serves as a reminder of the long-term consequences of major incidents on mental health. I worry that the response to covid-19 in the UK suggests we haven’t learned that lesson.

1: In terms of the response of many governments to covid-19, David Runciman suggests that “For now the war is all there is, and the peace will have to take care of itself.” I hope that’s not true. If there’s one lesson we always say we need to learn after every crisis, it’s that we need to do more planning for the “recovery phase”, the return to normality (even if that is a new normal). I hope the UK’s government is thinking on that.

2: Contrary to everything I thought I knew about myself, it turns out that I am the kind of person who stands in a queue outside Asda. Covid-19 has done strange things to us all.

3: Doctors often spend a lot of time moaning about the involvement of politicians in political decisions about healthcare. I appreciated this article from Political Violence at a Glance for giving a brief but thoughtful answer to the question: “In pandemics, should the experts or the politicians be in charge?”

4: Dies Irae is quoted in a lot of films. Who knew that Gregorian chant is so relevant to modern cinema?

5: Teacher training in England is a mess.

6: Mario’s moustache is there for a reason.

7: There’s a great article in the April/May 2020 edition of Courier—not online as far as I can tell—about what a company learned from deciding to pay all their staff the same salary. It didn’t work out for them. Courier does these articles on failed business experiments really well: it’s great to see failure embraced and learning shared rather than just pretending everything works all the time.

8: “There is no sweeter moment than passing a middle-aged man in lycra on a carbon-fibre road bike when you’re riding a Dutch bike in a dress.”

9: According to a lecture by Dr Mary Rogers who manages the Abbott Global Viral Surveillance Programme, from all the SARS-CoV-2 viruses genetically sequenced to date from over twenty countries, there is only variation in 149 positions in a 29,000nt virus (i.e. very little mutation and variation).

10: “Whether one agrees with Trump’s policies or not, his administration has accomplished much of what it set out to.” I sometimes think that the collective outrage at Trump’s policies obscures the fact that he delivers on them. I would never have believed on 9 November 2016 that Trump would still be in office today, let alone that he would have actually delivered on his outlandish promises.

11: Bats have weird immune systems.

12: Stoking anger and resentment in difficult times still sadly brings gainful employment for some, according to Andrew Tuck: “At the park there’s a man lurking by the bushes. He’s got a camera with a telephoto lens as long as his arm. He’s here not to spot a rare bird in the trees but to try to catch out people sunbathing, sitting on a bench, talking to someone who does not live in their household (I know this because a few hours later I check the tabloid sites to confirm my suspicions and there are his pictures). He’s also got a series of people allegedly cycling too close to one another. But they are not what they seem to be. He’s simply used the lens to make it look like people are super close by shortening the field of vision. With a country on edge, it’s incredible why anyone would try to sow unease.”

13: In the context of the Prime Minister’s covid-19 diagnosis, “Donald Trump described Johnson as a man who ‘doesn’t give up’. Which is about as disrespectful a thing one could say in the face of the tens of thousands of people who have died of the virus, and presumably just couldn’t be arsed to hang around.”

14: Canine life coach is a career option.

15: I read a lot of library books and have never really worried about catching infections from them. But Gill Partington seems to think I should worry (and according to this article, Public Health England has guidance on cleaning library books, which was also news to me).

16: It’s easy to forget the unprecedented pace of social change over the last hundred years, which means it’s easy for a news report from a century ago to knock my socks off with its attitude to gender politics.

17: The Government’s latest covid-19 graphic feels strangely reminiscent of certain 1990s weekend shopping trips.

18: It’s “unlikely in the extreme” that covid-19 will delay November’s US presidential election.

19: The Economist reckons that “apps built using Apple’s and Google’s new [covid-19] protocol ought to focus on providing information to technologically empowered human contact-tracing teams, not on automating the whole process.” I agree; I’m not sure whether or not that’s PHE’s view.

20: Streaming funerals online raises interesting theological questions.

21: By dint of being in the second half of the decade, I don’t think I can describe myself as being in my “early thirties” anymore. In Misbehaving, Richard Thaler suggested that people can no longer be considered “promising” once they turn forty. To wit: I’m now a “promising thirty-something.”

22: According to this headline, the ideal moment to invite more people to attend NHS services is the moment of greatest pressure on those services.

23: Some pigeons have their rectums checked for incendiary devices.

24: Some days, I just despair.

25: Van Gogh’s isolation in the Saint-Paul-de-Mausole asylum influenced his art in interesting ways.

26: A Time-ly reminder that hospitals are only as strong as their domestic workforce.

27: In The Sense of Style, Steven Pinker argues that “style earns trust. If readers can see that a writer cares about consistency and accuracy in her prose, they will be reassured that the writer cares about those virtues in conduct they cannot see as easily.” Events over the last few days have made me think a lot about how consistent and accurate advice is crucial for outbreak control, but I had been thinking in terms of ethics and efficacy. Trust is, of course, especially important too: people don’t follow advice they don’t trust. It’s normally the sort of thing I bang on about a lot, so it’s interesting to reflect on why it was so far from my mind this weekend.

28: “The rich world has no modern precedent but a 2017 paper by Keith Meyers, of the University of Southern Denmark, and Melissa Thomasson, of Miami University, on a polio epidemic in 1916 in America, made the lesson clear: closing schools hurts kids’ prospects. The younger ones leave school with lower achievements than previous cohorts and the older ones are more likely to drop out altogether.” (But but but…)

29: Today, I’ve had Adam Buxton’s take on the Quantum of Solace theme stuck in my head. It must be twelve years since I heard it on 6music, so I’ve no idea why my brain dragged that up!

30: I didn’t realise I was tired tonight until I woke up having falling asleep while reading in an armchair. I’m not sure this is correct behaviour for a promising thirty-something.
