UKRI's 2.7% PPAN headline compares 2029/30 with 2025/26 in cash terms. A longer-run inflation-adjusted comparison points to a roughly 16% contraction since 2021/22.

We introduce a method for visual and auditory feedback when exploring the fit of a model to data. Starting with a best-fit curve fit to data, the user can drag the curve to a new position and the computer will emit a squeal, becoming louder and more unpleasant as the discrepancy between curve and data increases. We demonstrate with four examples: a two-parameter curve fit to golf putting data, a four-parameter curve fit to dilution assays, a fit to cosmological data sensitive to the parameters of the Big Bang model, and a nonparametric Gaussian process fit to temperature readings.

As seems to be the case quite often these days on such occasions, I was asked to deliver “some remarks” after the conference dinner this evening at 170 Queen’s Gate. Over the year…
