    There’s one interpretation of the meaning of quantum mechanics that manages to skip a lot of the unphysical weirdness of the mainstream interpretations: it's de Broglie-Bohm pilot wave theory.

  • Why Quantum Information is Never Destroyed | Space Time

    If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang? Is the entire history of the universe perfectly knowable? Or has information somehow lost along the way?

    When is a Network a Network? Multi-Order Graphical Model Selection in Pathways and Temporal Networks Ingo Scholtes (ETH Zurich) We introduce a framework for the modeling of sequential data capturing pathways of varying lengths observed in a network. Such data are important, e.g., when studying click streams in information networks, travel patterns in transportation systems, information cascades in social networks, biological pathways or time-stamped social interactions. While it is common to apply graph a

  • Statistics of Violence as Special Case of Fat Tails

    5 بازدید

    A lunch discussion at MIT with computer science-data science researchers from MIT and NECSI. The talk is mostly about the methodology for dealing with fat tails, with application to violence. We show which claims can be made, and which ones cannot be made, from data, and "violence has dropped" is not one of them. We do not focus directly on Steven Pinker's popular science book (owing to some deficiencies), only indirectly as some people in political science made reference to it. The paper is here: http://

He's used complexity theory and quantum mechanics theory to predict that the Arab Spring would happen, and applies these approaches to social problems, health care, education, warfare, terrorism and more. First question. What is complexity theory, how does it relate to systems theory and how do you use this approach to deal with social, political issues and the like, and your message that no

  • Patterns and surprises in rich but noisy network data

    6 بازدید

    Patterns and surprises in rich but noisy network data - There has in recent years been a large amount of research interest in networks such as the Internet, the World Wide Web, citation networks, social networks, and biological networks such as metabolic networks and food webs. Empirical observations of networks like these are often noisy, containing measurement error, contradictory observations or missing data, but they can also be richly structured, with measurements of different types, repeated observati

  • Derek Thompson: "Hit Makers: The Science of Popularity in an Age of Distraction" | Talks at Google

    16 بازدید

    What makes an idea or product popular? That's the big question that Derek Thompson investigates in his new book, Hit Makers. Thompson draws on stories of hits from pop culture history, from the impressionist art canon to modern Star Wars sequels. His thesis: familiarity beats novelty and distribution beats content. Along the way, he explains the media landscape that gave rise to Donald Trump, the "myth" of viral content, and why people like things that are new--but not that new. Derek Thompson is a senior

  • Aaron Clauset "The trouble with community detection"

    8 بازدید

    A common task in network analysis is to seek a coarse-graining of the network into modules or communities, which describe the large-scale architecture of the network. For instance, we might want to find social groups within a network of friendships, functional modules among gene regulatory interactions, or compartments within food webs. However, different algorithms will return different communities for the same network, and this presents a conundrum for scientific interpretation: which set of communities a

But there’s one rule that most of us have been warned not to break: don’t divide by zero. How can the simple combination of an everyday number and a basic operation cause such problems?
