William Ellis His Book of Arithmetick
The Six and Twentieth Day of January Annoq Dom MDCCXXIX
Georgian arithmetic books were more than a record of work. Among the pages of calculations are ornate illustrations which show the student’s artistic skill and penmanship. This book is the work of a pupil called William Ellis.
They don’t teach mathematics like this any more. See more pages at the source. (Found via Kita Inoru.)
Santa Cruz Cops Experiment With ‘Predictive Policing’
“The police department in Santa Cruz, California, has begun an experiment that uses a mathematical algorithm to predict when and where certain crimes will be committed, and puts police on the scene before they happen. So far police have arrested five people using this technique of “predictive policing” and the rates of certain categories of crimes in the city have dropped significantly, perhaps as a result. The program has correctly predicted 40 percent of the crimes it was designed to monitor.”
Hmmm.. Predictive success or Waiting for the inevitable ?
