The BriefBook is a condensed handbook, or an extended glossary, written in encyclopedic format, covering subjects in statistics, computing, analysis, and related fields. It intends to be both introduction and reference for data analysts, scientists and engineers.

Along with Lee Smolin at the Perimeter Institute in Waterloo, Ontario, Amelino-Camelia has begun analyzing new gamma-ray data from NASA’s Fermi Telescope, launched in June 2008 (see image above right). The new data show similar delays in the arrival times of photons, which they believe will help physicists discriminate between these models. In this way, theories of not everything are falsifiable—giving them the edge over more ambitious theory-of-everything candidates.

DPMTA is a portable implementation of the Paralel Multipole Tree Algorithm (PMTA) which runs in a distributed environment under the PVM toolset. DPMTA provides application programmers with a easy to use interface to compute full N-body interaction solutions.

Although DPMTA is targeted mainly for the high precision requirements of Molecular Dynamics (MD) simulations, its generic interface makes it useful for many other applications. DPMTA has been successfully incorporated into several existing MD programs, including Sigma and NAMD.

The Standard Reference Data Program at NIST provides Distributor agreements to companies who wish to provide other organizations, clients, or customers copies of SRD databases for individual use.

For such distribution rights, Distributor will pay NIST fees as set forth in a signed distributor agreement. Such fees are subject to change and the Distributor must provide NIST a report of copies distributed with monies for each copy at least twice a year. Additionally, prepayment may be required.

"post-doctoral researcher in the Physics Department at the University of Maryland.... currently working with Prof. Michelle Girvan on topics related to complex networks. Ph.D. from the University of Western Australia School of Physics, studying supersymmetry and supergravity. "

My current research interests are fundamentally rooted in the areas of machine learning and network analysis. For over a decade, I have developed and studied large margin machine learning algorithms in the context of a range of perception tasks, such as object classification in video, sonar classification, hyperspectral anomaly detection and acoustic classification.

"I'm building tools to help organize, explore and visualize massive information sources, an enterprise that unifies my lifelong interests in computers, education, physics and design.

Specifically, I've started infochimps.org, a community to build the world's best repository of free, open data -- a kind of wikipedia for datasets. Sites such as Wikipedia can tell you something about everything -- infochimps.org will tell you everything about something."

Hofman, a graduate student at Columbia University, downloaded the list when the abstracts came online a few months ago. He used the data to create a network, linking physicists who were listed as co-authors on a talk.

To the right you’ll see the visualization he ended up with. It’s a little tricky to interpret (and also quite preliminary), but the basic idea is that each of the 6755 physicists is shown in order on both the x- and y- axis. Blue points indicate co-authors, and white points show no affiliation. Large clumps of blue show communities, most of which seem to correspond to particular subfields.

Over the past several months, our group in the Department of Physics at the University of Washington has begun looking at ways to implement “cloud computation” schemes through Amazon Web Services (AWS). Our group specializes in scientific computation and has been developing the widely used FEFF codes for calculations of x-ray spectroscopy and electronic structure in molecules and solids. Our aim is to evaluate the usefulness of AWS elastic compute cloud, aka EC2,

Three Lectures by Hans Bethe

IN 1999, legendary theoretical physicist Hans Bethe delivered three lectures on quantum theory to his neighbors at the Kendal of Ithaca retirement community (near Cornell University). Given by Professor Bethe at age 93, the lectures are presented here as QuickTime videos synchronized with slides of his talking points and archival material.

The Trader had come to Lehman only a year ago, after being recruited from a rival firm. He’d studied physics as a grad student, then come to Wall Street as the tech bubble and the aggressive gentrification of the Giuliani years remade Manhattan into a banker’s playground, a place where a $2 million salary could seem like the norm.

....But by Saturday, September 13, Lehman Brothers teetered on the precipice of bankruptcy after Barclays and Bank of America walked away from a deal. The Trader was certain of little, except that he was a lot poorer. The unvested stock from his previous year’s bonus, once worth $3 million, was now reduced to a scant $6,000.

open-source Python implementation of the Fast Multipole Algorithm (FMM) for scientific applications.

The FMM can be used in many scientific computing applications: the simulation of many stars, electrostatics, the calculation of atoms or molecules out of equilibrium, and particle methods for continuum problems. The advantages of the FMM can be huge when large numbers of particles are involved, as it reduces the complexity of calculations from O(N2) to O(N).

An interdisciplinary effort dedicated to creating the world's largest data center for time series and developing algorithms to understand various aspects of those time series

The master of differential geometry and entertaining textbooks gives a series of video lectures: http://en.wikipedia.org/wiki/Michael_Spivak

We are building an “astrometry engine” to create correct, standards-compliant astrometric meta data for every useful astronomical image ever taken, past and future, in any state of archival disarray.

Looks like a great blog... discovered via trackback to datawrangling. More interesting links in the blogroll.

Dr Brian Cox will introduce the fundamental building blocks of the universe as we know them atthe turn of the 21stcentury.

The primary emphasis of the lectures will be the study of non-perturbative regimes of string theory. The first lecture will be broad and at a general level, touching on a number of topics.

In this 3-lecture series I will discuss the basics of string theory, some physical applications, and the outlook for the future. I will begin with the main concepts of the classical theory and the application to the study of cosmic superstrings.

5 video lectures: Cosmology for Beginners
by Paul Stankus, Oak Ridge National Lab

Introduction to particle physics videos, exotic particles, accelerators, detectors, standard model etc.

Below you can find the pdf files of handwritten lecture notes for Coleman's course (transcribed by Brian Hill). The notes come in two large files, each around 6.5 Mb.

A course of seven lectures covering the essential principles of thermodynamics and phase equilibria. It is designed for an interdisciplinary audience and assumes little prior knowledge.

Recorded in 1975-1976.

The videos shown here were transferred to DVD in 2007 straight from surviving VHS tapes, which were, in turn, copied from the original source tapes.
