VIDEO lecture: First steps in scientific data visualisation using d3.js - by Drew Conway

Mike Dewar (Data Scientist, bit.ly), presents a talk on getting started with data driven design in Javascript to the New York Open Statistical Programming Meetup on Jan. 12, 2012. Mike Bostock's d3 javascript library has lately taken the internet by storm, being the engine underlying a very beautiful set of visualisations (mbostock.github.com/d3/). Because of this, many have investigated d3.js as a potential addition to their current visualisation stack, only to fall over one of some common hurdles. This talk will demonstrate how to clear these first few hurdles, including:
- how to create and serve nice data objects
- how to use chrome's console to inspect and play with your visualisation,
- how d3 interacts with the document object model,
- how to draw arbitrary SVG objects,
- how to use d3.layout to relieve you of a few common graph-vis tasks.

The talk will be useful to those who are curious about using d3.js and wants to get started making interactive and dynamic statistical visualisations. You can download the slides (all written with d3.js) from Mike Dewar's Github: github.com/mikedewar/d3talk

Self-Improving Artificial Intelligence and the Future of Computing

Steve Omohundro for the Stanford University Computer Systems Colloquium (EE 380) presents fundamental principles that underlie the operation of "self-improving systems," i.e., computer software and hardware that improve themselves by learning from their own operations.

Arthur C. Clarke - "Fractals of Science" or "The Colors Of Infinity"

Arthur C. Clarke presents this unusual documentary on the mathematical discovery of the Mandelbrot Set (M-Set) in the visually spectacular world of fractal geometry. This show relates the science of the M-Set to nature in a way that seems to identify the hand of God in the design of the universe itself. Dr. Mandelbrot in 1980 discovered the infinitely complex geometrical shape called the Mandelbrot Set using a very simple equation with computers and graphics.

 

Arthur C. Clarke's soft-spoken style sets the "common man" at ease, and his pinpoint commentary makes the concept of fractals easy to understand. One need not be a stellar mathematician to grasp the concepts and why they are profound. The experts are trotted out, and they, too, explain fractal geometry in ways that are accessible to everyman.

 

Fractals are part of our lives, and maths informs everything that exists, whether natural or man-made. In the novel, a software engineer tries to create a program that sets the flapping of a bird's wings to music using mathematical equations. That is exactly what fractals seem to do; they describe events in nature in mathematical ways, and the section of "Colors" which discusses this is eye-opening.

Google Workshop on Quantum Biology: Classical and Quantum Information in DNA

DNA stores and replicates information. Special sequences of different nucleic acids (adenine, cytosine, guanine, thymine) encode life's blueprints. These nucleic acids can be divided into a classical part (massive core) and a quantum part (electron shell and single protons). The laws of quantum mechanics map the classical information (A,C,G,T) onto the configuration of electrons and position of single protons. Although DNA replication requires perfect copies of the classical information, the core that constitutes this information does not directly interact with the copying machine. Instead, only the quantum degrees of freedom are measured. Thus successful copying requires a correct translation of classical to quantum to classical information. It has been shown that the electronic system is well shielded from thermal noise. This leads to entanglement inside the DNA helix. It is an open question if this entanglement influences the genetic information processing. In this talk I will discuss possible consequences of entanglement for the information flow and the similarities and differences between classical computing, quantum computing and DNA information processing.
