teaching the SVD this week.
some historical elements i've learned...

beltrami wrote the decomposition down in 1873.
jordan found it independently the next year.
sylvester called the stretches canonical multipliers in 1889.

schmidt proved the best low-rank approximation he time eckart & young put the same theorem in psychometrika in 1936, it was already decades old.

what was missing was a way to compute it that didn’t square every number in sight: golub & kahan fixed that in 1965. the version that ran for the next twenty years was golub & reinsch, 1970.

golub drove a car whose license plate read PROF SVD. lol...

📰 New paper out in @Chem_Eng_J!

Can AI help us find better working fluids for refrigeration and heat pumps? These fluids have to perform well thermodynamically, but also be safe and environmentally sustainable, and that combination is hard to get

The result is a scalable framework that goes from molecular generation to process-relevant performance.

Great work by @manu_ru_bo and Tiago Eusébio, in collaboration with Sabrina Belén Rodriguez Reartes and Felix Llovell

Structure alone supports efficient visual computation in the Drosophila visual system

Understanding the extent to which measured synaptic wiring determines computation remains a central challenge. Here, we couple the proofread adult Drosophila melanogaster connectome to an anatomically faithful model of its eye. Visual information is inputted in the eye model, then passed to the connectome, and finally read from a Kenyon-cell-centered linear decoder. This creates a connectome-only model in which the anatomical graph and eye geometry are fixed and only scalar synaptic gains and neuronal thresholds may be learned. The model supports multitask vision, including color discrimination, shape classification, and numerical discrimination that follows a ratio-dependent scaling characteristic of approximate number perception. To test whether precise connectivity is consequential under wiring economy, we compare the biological graph to randomized ensembles that increasingly preserve biological synaptic constraints. At matched wiring cost, the biological network consistently yields

102 organic chemists shown real vs AI-generated molecules. Couldn't tell them apart — 62% accuracy ≈ random. That's CoCoGraph: graph diffusion with 100% chemical validity, 534K params vs 4.6M for comparable models. Constraints in the math, not the model.

Out today in @ScienceMagazine: with the amazing Haochuan Cui, Yiling Lin, & @LingfeiWu, we analyzed 3.6 million scientists publishing 1960–2020. The findings reshape a century-old debate about age and scientific creativity.
