Falsifiability and Gandy’s variant of the Church-Turing thesis

by Artem Kaznatcheev in Evolutionary Games Group

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 […]... Read more »

Whitman Was Not a Neuroscientist

by The Neurocritic in The Neurocritic

Do I contradict myself?Very well then I contradict myself,(I am large, I contain multitudes.)-Walt Whitman, "Song of Myself" (from Leaves of Grass)Science is the search for objective truth based on physical laws of the universe. Scientific theories try to explain the consistent and predictable behavior of natural systems. They are generally reductionist, meaning that complex systems are reduced to simpler and more fundamental elements. The principles of physics, for instance, are expressed in th........ Read more »

The Holographic Universe [we might Live in!]

by Gabriel in Lunatic Laboratories

Are you feeling a little… flat? Well that might be because you are only in 2 dimensions. I know what you’re thinking, insane! Well first check the name of the business and second, check out the science. In fact, it may seem like a joke, but the math suggests that it could very well be true and with it could come a deeper understanding of the universe. Testing this hypothesis (which was first made in the late 90’s) has been harder to do than you might think, but that has now changed. We are........ Read more »

For These Bats, the Best Falsetto Wins Over the Ladies

by Elizabeth Preston in Inkfish

A bat’s voice is its livelihood. Chirping and squeaking at just the right frequencies lets it echolocate food and stay alive. Sounding pretty isn’t the point—except when it is. For the first time, scientists think they’ve found a bat species in which females choose mates based on their voices. Even if a lower-frequency squeak might […]The post For These Bats, the Best Falsetto Wins Over the Ladies appeared first on Inkfish.... Read more »

It Only Takes Six Generations to Turn a Brown Butterfly Purple

by Elizabeth Preston in Inkfish

Evolution can seem like a slow way to get things done. It took more than a billion years for Earth’s life forms to try having more than one cell. In the famous March of Progress illustration showing an ape becoming an upright human, you can almost hear the stoop-shouldered cave guy in the middle groaning, “Hurry […]The post It Only Takes Six Generations to Turn a Brown Butterfly Purple appeared first on Inkfish....
