Is that a real Zizek quote? Or one of the memetic parodies?

A winter weekend some years ago, I went through several published rankings to see if there is consensus. There is some agreement that New Hope and Empire Strikes back are top. Last Jedi and Rogue One are quite polarizing.

You are not wrong, but you are being too harsh. K-means for market segmentation is an *exploratory* and easy-to-interpret way to summarise multivariate data. It's fine IMO, but with lots of caveats, of course, particularly in the questionnaire design.

Same pattern for 400m. I have been doing these after each olympiad or world champ.

Just in case there was any doubt that today's 400m final in Tokyo was insane, here I made a chart with the top 10 times in the last 50 years (excluding 2020).

The 1980s were also insane but for other reasons (95% eastern Europe, 50% M. Koch)

2000-2010 is mostly the formidable Sanya Richards.

I took up online chess (around 2017) and Naroditsky was a central celebrity streamer along my journey (esp. post-pandemic). Great commentator of big matches. Such a well-rounded (he had a history degree from Stanford), smart, kind person. These are awful news and I am still a bit shocked.

I love papers that have it all: context, descriptive stats, concrete examples, theory model, public data, private data, tons of figures, empirical estimates, identification, policy implications, etc.

If one works in education, the effect has been immediate and transformative, for better or worse. Homework and term papers will never be the same, even if (after the collapse) we have to live with open source models running on local servers.

This. Kirk Douglas was born Issur Danielovitch. I believe Michael Douglas was always Michael Douglas.
