3:15 AM | Falsifiability and Gandy’s variant of the Church-Turing thesis
In 1936, two years after Karl Popper published the first German version of The Logic of Scientific Discovery and introduced falsifiability; Alonzo Church, Alan Turing, and Emil Post each published independent papers on the Entscheidungsproblem and introducing the lambda calculus, Turing machines, and Post-Turing machines as mathematical models of computation. The years after saw many […]

12:03 AM | Forget Everything You Thought You Knew About “Horsepower”
Every time the newest model of truck or car comes out, the car manufacturers loves to tell you how much “horsepower” the vehicle has, conjuring up visions of muscular stallions galloping through the countryside. But I put the term “horsepower” in quotes because these visions are misleading. See, in our modern world, horsepower is simply a scientific unit that we accept as a standard. But to understand what it actually means, you have to understand where it actually […]

1:59 PM | A Strange Turn into Research Policy.
Twitter is a fascinating, self-contradictory place for scientists. A huge and robust community. By turns enlightened and enlightening, ruthlessly orthodox, whimsical and humorless, unified and fragmented, quixotic and hypocritical, absolutist and relativist. Just as it is impossible to pin down any individual to a label-board, so the community of scientists and academics on twitter defies […]

1:32 PM | When human activity can ‘trigger’ earthquakes
Many centuries ago, human activity was believed to result in earthquakes – If we did not sufficiently appease the gods, mighty Tepeyollotl, heart of the mountains, would vent his calamitous rage with a terrifying, tumultuous upheaval of the earth itself. Nowadays most of us know better (although that still doesn’t stop some religious nuts from…
