And as long as the AI is perceived as the engine of a new industrial revolution, decision-makers will imagine it can do so, and task people to make it so.”

Unifying same- and different-material particle charging through stochastic scaling
Triboelectric charging of insulating particles through contact is critical in diverse physical and engineering processes, from dust storms and volcanic eruptions to industrial powder handling. However, repeated experiments revealed counterintuitive charge patterns, including variable impact charge under identical conditions, charge sign reversal with repeated impacts, and bipolar charging of differently sized particles. Existing computational models cannot predict these patterns; they either re…
