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 […]

9:02 PM | What Is A Computer, Really?
What Is A Computer, Really? Look at the picture above. Believe it or not, that person is operating an extremely sophisticated mechanical calculator, capable of generating tables that evaluate functions called “polynomials.” Although a graphing calculator can do that, a pocket calculator certainly can’t. The … Continue reading → The post What Is A Computer, Really? appeared first on The Physics Mill.

5:44 AM | The Stochastic Resonance Program (Part 2)
guest post by David Tanzer Last time we introduced the concept of stochastic resonance. Briefly, it’s a way that noise can amplify a signal, by giving an extra nudge that helps a system receiving that signal make the jump from one state to another. Today we’ll describe a program that demonstrates this concept. But first, […]

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…
