• "The LM13600 has designed by Bill Gross and myself in less than 5 minutes." Which is a humbling anecdote about a classic OTA amplifier. But, as the story goes on, it makes sense: it's just "two of something else" with a buffer, and the design brief was "make something somebody can learn to layout 16-pin DIP with". Didn't matter what the thing was, just needed to have 16 pins. And there you are.

  • "The most notable “discovery” in the dataset was that if you simply plotted the number of steps versus the BMI, you would see an image of a gorilla waving at you (Fig. 1b). While we teach our students the benefits of visualization, answering the specific hypothesis-driven questions did not require plotting the data. We found that very often, the students driven by specific hypotheses skipped this simple step towards a broader exploration of the data. In fact, overall, students without a specific hypothesis were almost five times more likely to discover the gorilla when analyzing this dataset (odds ratio = 4.8, P = 0.034, N = 33, Fisher’s exact test; Fig. 1c). At least in this setting, the hypothesis indeed turned out to be a significant liability."
  • "The truth is that if you say you want more children from deprived areas to be able to go to university, then don’t faff around with entry tariffs: invest in Sure Start centres, preschool groups, subsidised childcare and properly resourced primary schools. Make benefits genuinely accessible and life-supporting. Better still, stop whole sections of society being condemned to underpaid, vulnerable, soul-destroying labour while others cream off inordinate wealth from the profits of that labour." Stefan Collini talking a lot of sense about what universities are, and what the lurch towards consumerising them more than ever in the past ten years has led to. It is not pretty.
