I do Machine Learning at Spotify. I used to do Quantum Optics and Quantum Information theory.

Think deeply of simple things.

The greatest lie of all.

They know very well that we’ll be going on a bear hunt every ten minutes for the next hour at least.

Great that the city council’s illustration of ‘amazing places to stretch your legs’ shows the reality of walking with a pram in the city: cars entirely blocking the pavement because the council won’t do anything about it

Would watch a biopic on the Heathrow crocodile

Holiday reads (spending my work’s education budget before the end of the year)

Isn’t it beautiful? The snowy roundabout setting. The wrapping bow. The little cottage on top. The hearts on the bottom. The curly tail 👌🏻 Thank you Mjölby

The big Swedish Christmas event for me is the wrapping of the Mjölby potato roundabout

I have been listening to the 8 disc live ‘REM at the BBC’ a lot

Twin moon halos at 22° and 44° seen now from my garden. The halos are moonlight refracted and reflected through still, floating ice crystals in the stratosphere (it’s -1C on the ground and still) And to the right of the full moon, Jupiter.

Half the pavements in England and Wales are impassable with a wheelchair or pram because they’ve got cars parked on them but sure the homeless man outside tesco express is the real nuisance here

This episode is about CJ getting a threatening email but it made me laugh that the communications director of the West Wing would only have inbox 4 when she came into work. The good old days of email.

I don’t know if it’s obvious or not but the most useful to my physics work is probably the Lindblad master equation for open quantum systems.

A big part of my work in recent years has been on probabilistic detection of changes and anomalies in multivariate time series. For the past 52 days I’ve mostly been living in a neonatal intensive care unit with our new baby twins, watching these streaming time series.

Ooh, an FT piece on quantum computing. Oh, no.

I like that the picture of Euston station during ‘major disruption’ looks just like Euston station at all times because of the surprise platform announcement system

10 years ago this month I was walking with a friend in the north of Sweden above the arctic circle, no contact with the outside world for a couple of weeks. It was great. I put some photos here —

New addition. It’s been a long time since I’ve thought about Fractal Geometry and this one looks fun.

So a new social thing calls for a shelfie. I’ve been adding to this textbook collection since school and it brings me a lot of joy.

Do you have a favourite here? Also, if you have your own textbook shelfie please share, I love to see them.
