isomorphismes: Gerald Jay Sussman on biology & computation. The human genome is 1 GB. So is Windows OS. We have no idea how to program a 10^12-unit thing like a human, or a cow. A salamander regrows three elbows if you break off its arm and reattach it — responding to local errors. We have no idea how to write computer vision in a few steps like neurons do. Program efficiency doesn’t...

Math Class Needs to Be More Engaging
laboratoryequipment: The precarious decline in children’s participation in mathematics can only be reversed by tackling a complex mix of factors, including positive and negative attitudes of a student’s parents, peers and teachers, new research from the Univ. of Sydney has found. The study, published in the International Journal of Educational Psychology, is the first to reveal that ‘switching...

When Cellular Automata Come to Life →
“Cellular automata are probably the closest things to machine life that most people have gotten an opportunity to experiment with in recent years. John Conway invented a piece of software titled the Game of Life in 1970. He carefully set up the rules to create a balanced world. While this might sound like old news, it has allowed scientists to actually simulate certain real world...

Crowd Memory: Learning in the Collective.  →
arxiv-cs: Authors: Walter S. Lasecki, Samuel C. White, Kyle I. Murray, Jeffrey P. Bigham Crowd algorithms often assume workers are inexperienced and thus fail to adapt as workers in the crowd learn a task. These assumptions fundamentally limit the types of tasks that systems based on such algorithms can handle. This paper explores how the crowd learns and remembers over time in the context of...

Thermodynamic Principles in Social Collaborations.... →
arxiv-cs: Authors: Huan-Kai Peng, Ying Zhang, Peter Pirolli, Tad Hogg A thermodynamic framework is presented to characterize the evolution of efficiency, order, and quality in social content production systems, and this framework is applied to the analysis of Wikipedia. Contributing editors are characterized by their (creative) energy levels in terms of number of edits. We develop a definition...

bellalison: I think the main reason I don’t like 4/20 is that it’s not reduced to the lowest denominator.

Game of go: A complex network →
From their network, the researchers obtained these patterns (each one with 9 intersections) which show the most frequent moves or combine strategic moves (these are patterns on which eigenvectors associated with three large eigenvalues from the weighted adjacency matrix of the graph are localized). The top line corresponds to the ten most frequent moves in go. The middle line isolates patterns...

Tensor Networks for Entanglement Evolution.  →
arxiv-cs: Authors: Sebastian Meznaric, Jacob Biamonte The intuitiveness of the tensor network graphical language is becoming well known through its use in numerical simulations using methods from tensor network algorithms. Recent times have also seen rapid progress in developing equations of motion to predict the time evolution of quantum entanglement [Nature Physics, 4(\textbf{4}):99, 2008]....

The sum of digits of prime numbers is evenly... →
On average, there are as many prime numbers for which the sum of decimal digits is even as prime numbers for which it is odd. This hypothesis, first made in 1968, has recently been proven by French researchers from the Institut de Mathematiques de Luminy.
