Some neurons are active when adding, others when subtracting
Most elementary school children probably already know that three apples plus two apples add up to five apples. However, what happens in the brain during such calculations is still largely unknown. The current study by the Universities of Bonn and Tübingen now sheds light on this issue.

New work extends the thermodynamic theory of computation
In a paper published in Physical Review X on May 13, a quartet of physicists and computer scientists expand the modern theory of the thermodynamics of computation. By combining approaches from statistical physics and computer science, the researchers introduce mathematical equations that reveal the minimum and maximum…

Bayes’ Theorem – What is it and what is it good for?
Bayes’ Theorem tells us how to rationally assess the probability of a certain statement of interest being true, given some evidence. Insofar as science consists in creating hypotheses, collecting e…

Reddit, Stumbleupon, Del.icio.us and Hacker News Algorithms Exposed
It is greatly ironic that algorithms, the quintessential example of all that is not human, would be so fundamental to social media. Last week I wrote a post about how Google gathers user data. This week I continue by exposing how popular social media websites use algorithms to ut...

The Fourth Quadrant: a Map of the Limits of Statistics (by Nassim Nicholas Taleb)
Statistical and applied probabilistic knowledge is the core of knowledge; statistics is what tells you if something is true, false, or merely anecdotal; it is the "logic of science"; it is the instrument of risk-taking; it is the applied tools of epistemology; you can't be a modern intellectual and not think…
