While my arXiv newspage today had a puzzling entry about modelling UFOs sightings in France, it also broadcast our revision of Reliable ABC model choice via random forests, version that we resubmitted today to Bioinformatics after a quite thorough upgrade, the most dramatic one being the realisation we could also approximate the posterior probability of […]
Each square growing out from the centre is rotated a fixed angle from the previous one. For most angles, this creates visible structure such as defined spiral arms. But at the golden angle the corners are spread out relatively evenly. Nature takes advantage of this in plants like the Romanesco Broccoli to evenly spread out the disgusting-tasting broccoli florets as they grow. [code]

At least not directly. But the owner of the three-month-old cafe in Seattle’s Mount Baker neighborhood has been able to sneak in principles from his math background into his cafe in surprising ways.
