I feel embarrassed! Despite being from Glasgow, until now I've never made the connection between the River Kelvin (and the surrounding Kelvingrove and Kelvinbridge), the statue in the park of someone called Baron Kelvin, and the unit of measurement.
This doesn’t totally solve the issue of SELECT’ing first then filtering, but for complex queries I’ve found CTEs very useful (whenever the database/SQL dialect supports it).
The Times could perhaps be leaning “right”. But the FT is, in my opinion, a legitimately neutral publication. At least through Britain’s default neoliberal lens.
