Don't say we don't spoil you - today we've added cases in England split by pillar of the testing programme so you can look at changes in mass community testing (pillar 2 including LFD) separately from changes in NHS testing (pillar 1) coronavirus.data.gov.uk/deta…

Just got gently corrected for calling an ophthalmologist “Dr” instead of “Miss” (since she is also a surgeon), and y’all, England is weird. I’m just waiting for the @DGlaucomflecken episode where he moves to England and suddenly becomes Mr Glaucomflecken.

Central worry with confidence/credible intervals: they can mean a variety of things about a model: mostly technical things irrelevant to decision-making. But they're presented to SOUND like: "a range in which the actual result is 95% likely to lie." They almost never mean that.

A while back, I TAed a course at Harvard called “Magic of Numbers.” I think the profs thought the name would improve morale. Instead many students were upset to have such a patronising course name on their transcripts after nontrivial work in modular arithmetic and combinatorics.
Now taking suggestions of what we should rename maths to make it less scary. thetimes.co.uk/article/give-…

Grateful today for my first-ever opportunity to vote in the UK... especially at a time when I'm feeling a bit disenfranchised in the US.

I'm late retweeting this, but it's an important article and thread. As a US/UK dual citizen, I'm often surprised at how many misconceptions are commonly held on each side about healthcare access across the pond.
NEW: for the last few weeks I’ve been digging into how the huge pressures on the NHS — both immediate and longer-term — are increasingly forcing Britons to go private. The result is this, the first edition of what will be my weekly data-driven @FT column: ft.com/content/dbf166ce-1ebb…

Nice to see an evidence-based response on this. As for my own experience, I attended separate PhD programmes on opposite US coasts in physics and in maths but only had funding to complete one PhD, so did maths. I love physics, but I guess it didn't have quite enough maths for me.
🧵I was on GMB this morning responding to Katherine Birbalsingh's comments that girls aren't choosing physics at A-Level because they don't like the hard maths and are more empathetic than boys... I had a *lot* more to say but sadly didn't get time. So here is a thread! 1/14

Should maybe add: part of why I liked physics to begin with is I attended a state magnet school for maths and science my last 2 years of secondary school and took 5 semesters of physics there from a really legendary physics teacher. Inspiration matters. physics.duke.edu/news/passin…

But numbers also matter. One reason I left physics was having budding collaborative relationships with junior faculty members from 3 different physics departments crash and burn when they asked me to date them, when I was a grad student. Occ. hazard of male-dominated fields.

All the data. Apart from personally identifiable data of course.

Kind of straying from usual topics here, but can I ask a maths education question? Our local secondary school's sole instruction provided to the top maths set (a sizeable fraction of the class) in year 9 is a single 100-minute lesson per week. Is this normal in England?

Technically there's also one study period rebranded as a maths period, but I've learned the students merely spend that time working independently or otherwise entertaining themselves while babysat by a teacher from another subject catching up on work in the back of the classroom.

ONS continuing their quiet, incredibly important analysis; here looking to see if vaccination causes problems that weren't picked up in the trials, but might show up in population-level data.

Paging @kallmemeg, @statsgeekclare or anyone else who might know someone on the team tweeting from @UKHSA  account: is it possible to turn off this daily tweet on sequenced cases? Based on replies, it seems to be causing serious confusion. Eg could replace with SGTF % updates.
#OmicronVariant latest information 17,269 additional confirmed cases of the #Omicron variant of COVID-19 have been reported across England and Northern Ireland. Confirmed Omicron cases in the UK now total 177,201.

To be clear, I'm sure neither of the people I tagged are responsible for this daily tweet on sequencing. I was just hoping that they (or some other observer) might know how to contact the right person.

Okay, been told @SMHopkins might be a good contact for this. It's just, many people in replies seem to think this daily tweet is meant to be an estimate of daily Omicron cases (and are getting really confused), when by now it’s basically only measuring daily sequencing capacity.

This is the best Christmas present I could have received. My son with #ATRXSyndrome is not quite eligible but will be soon. Along with all the kids in his school, all clinically vulnerable. 300,000 CV kids in the UK. A weight is lifted & I’m so grateful. Happy Christmas 🎄

The UK coronavirus dashboard has been a spectacular accomplishment. So many people, including myself, are indebted to you and your colleagues for the tremendous effort that went into it. You should be very proud.
Some personal news (a 🧵): On 4 October 2021, I resigned from my role as the Deputy Head of Software Engineering for Web and Data at @UKHSA. This means that 1 January 2022 will mark my final day in the agency — but *not* on the dashboard, so this is not goodbye. ...[1/10]

Actually I’m kind of irritated that Twitter re-rotated the png image in my first tweet. The image in the original tweet was supposed to be upside down as well. I had to re-export as a jpeg to get Twitter to display it the “right” way up.
