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: Talking about how to influence politicians, Professor Dame Sally Davies told the HSJ ”You’ve got to think ‘where are they coming from’ and frame the issues so it has salience for them.” When I was lucky enough to work alongside her, I learned a huge amount from just watching how Sally worked. It still strikes me as notable that many doctors take the approach she describes with their patients but don’t do the same in political discussion. 

2: Leaving portfolios until the end of the appraisal/CPD year is a bad idea. This isn’t really a lesson specific to this year, but I never seem to learn it regardless. 

3: Some days are longer and busier than others. 

4: In Grandeur and Greed, Giles Smith refers to Bassano’s painting The Animals Entering Noah’s Ark as having “the worst depiction of an elephant in any exhibited artwork in a major gallery”. It took me a while to spot it, which rather says it all: I think he might be right. 

5: It’s always lovely to reconnect with an old friend. 

6: Just as the first casualty of war is truth, the first casualty of pandemics is common sense. 

7: The more intensely I work, the more I lose perspective. This is a useful trait, great for total immersion in complex projects, for trying to untangle a complicated outbreak or for trying to make a useful and structured text from lots of conflicting ideas. But I’m learning that it’s not a helpful trait when working intensely to others’ plans, because it’s easy to become fixated on the flaws and fault lines of my little corner rather than seeing the bigger picture taking shape. Rest helps to restore perspective. 

8: I’m not sure whether I actually learned anything from it, but David Marchese’s interview with Aaron Sorkin in The New York Times Magazine was brilliant. 

9: I’ve learned what book reviewers think is the point of book reviews. 

10: Being woken in the middle of the night when on call seems to get even less fun each time it happens, and covid-19 means it is happening a lot. 

11: Sleeping for 12-and-a-half hours straight is still a thing that happens when I’m tired enough. 

12: The Electoral Commission recommends postponing the May elections until the autumn, and I’m surprised by how conflicted I feel about that. 

13: Mind-gardening is a thing. Apparently. 

14: I can’t remember the last time a cartoon stopped me in my tracks like this one by Ella Baron. 

15: Philippe Descamps’s article in Le Monde Diplo on cycling in Copenhagen was interesting—particularly the bit about having predictable provision according to the road’s speed limit. The article suggests that only 6% of daily journeys in Copenhagen are on foot, which I suspect is an artefact of the definition of “journey”: almost everyone will walk some distance on foot each day, and on the occasions when I’ve visited Copenhagen, I’ve enjoyed the fact that provision for pedestrians is as thoughtfully considered as the provision for cyclists. 

16: Despite it being (apparently) very commonly taught in schools and universities, it is only at the age of 34 that I’ve first heard of the “five paragraph essay”. 

17: The good people of Newcastle are, it seems, panic-buying chicken. 

18: Snail facials are exactly what they sound like. According to Race Across the World, there are 52 species of hummingbird in Costa Rica. This came as a particular surprise to me as I thought ‘hummingbird’ was a species. I know nothing. 

19: Even a fairly crude “guy walks into a bar joke” can be a delight when it’s well written. 

20: I usually walk to work: it takes a little under an hour, which is only a little longer than it takes by Metro or car. Today I learned that if the rest of the world self-isolates, it actually only takes nine minutes to drive. 

21: Traveling from London to Mallorca by train, foot and ship is easier, but less environmentally efficient, than I’d have guessed. 

22: I’ve never thought before about the fact that escalator machinery on the London Underground wears unevenly because of “the weight of those who dutifully stand on the right”. 

23: This time three months ago, I thought it was extraordinary that a Government would remove the right of citizens to live and work in any country in the EU. Never did I imagine a British Government could remove citizens’ rights to the extent that they have to stay indoors. I’m living in extraordinary times. 

24: Most of the time, letters responding to articles in medical journals add very little. Sometimes, though, they add completely new insights which change my perspective on an issue: pointing out that health improvement interventions that go along with screening tests are usually ignored in analyses of the effectiveness of screening programmes is a great example. 

25: I don’t think I’ve ever seen an episode of Doctors. 

26: There’s a reason why it feels strange to walk on a stopped escalator. 

27: It’s been too long since I last listened to Reply All. 

28: “Self-sacrifice has always been an implicit part of being a doctor. It is a source of both pride and pain, and why, on the whole, doctors and nurses deserve our respect. Rarely has it been so called upon as in the covid-19 crisis.” 

29: It’s tough to be a spy in a country in covid-19 lockdown. 

30: An article by Peter Blegvad in the latest Brixton Review of Books made me think quite a lot about the relative accuracy of each of imagination, observation and memory: a theme explored in quite a few novels I’ve read, but which I don’t think I’d really considered in art before. 

31: “Pineapple is the smell of masculine.” Apparently.
