Van Jacobson PARC A New Way to look at Networking on: Google Video Today's research community congratulates itself for the success of the internet and passionately argues whether circuits or datagrams are the One True Way. Meanwhile the list of unsolved problems grows. Security, mobility, ubiquitous computing, wireless, autonomous sensors, content distribution, digital divide, third world infrastructure, etc., are all poorly served by what's available from either the research community or the marketplace. I'll use various strained analogies and contrived examples to argue that network research is moribund because the only thing it knows how to do is fill in the details of a conversation between two applications. Today as in the 60s problems go unsolved due to our tunnel vision and not because of their intrinsic difficulty. And now, like then, simply changing our point of view may make many hard things easy.
Guido van Rossum Google Python 3000 on: Google Video The next major version of Python, nicknamed Python 3000 (or more prosaically Python 3.0), has been anticipated for a long time. For years I have been collecting and exploring ideas that were too radical for Python 2.x, and it's time to stop dreaming and start coding. In this talk I will present the community process that will be used to complete the specification for Python 3000, as well as some of the major changes to the language and the remaining challenges. Guido van Rossum is a computer programmer who is best known as the author and Benevolent Dictator for Life of the Python programming language.
Interview on: The Vega Science Trust Swiss microbiologist, corecipient with Daniel Nathans and Hamilton Othanel Smith (qq.v.) of the United States of the Nobel Prize for Physiology or Medicine for 1978. All three were cited for their work in molecular genetics, specifically the discovery and application of enzymes that break the giant molecules of deoxyribonucleic acid (DNA) into manageable pieces
Paul Davies Imperial College Black Holes, Wormholes and Time Travel on: The Vega Science Trust The idea of time travel makes great science fiction, but can it really be achieved? Paul Davies, visiting Professor in Physics at Imperial College, describes wormholes in space and other ways that might allow travel into the past or future.
C. Johnson University of Southern California String Theory Part III on: CERN 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. The remaining lectures will be more detailed, exhibiting some key tools and phenomena which have formed the foundation for several recent advances in the field. Among these are D-branes, which will be studied from several points of view, leading to ideas such as strong/weak coupling dualities, open/closed dualities, holography, and gauge/gravity dualities. If time permits, the last lecture will discuss minimal string theories, which are simple but powerful exactly solvable systems which exhibit a range of key non-perturbative phenomena.
Will Noel Walters Art Museum The Archimedes Palimpsest on: Google Video The Archimedes Palimpsest is a 10th Century medieval manuscript that is the subject of an ongoing technical, scientific and conservation effort at the Walters Art Museum in Baltimore, Maryland. Since 1999, the multidisciplinary team has been disbinding, conserving, imaging, analyzing, transcribing and studying the 174 parchment folios - yielding approximately 400Gb of data to date.
Practical Common Lisp on: Google Video In the late 1920's linguists Edward Sapir and Benjamin Whorf hypothesized that the thoughts we can think are largely determined by the language we speak. In his essay 'Beating the Averages' Paul Graham echoed this notion and invented a hypothetical language, Blub, to explain why it is so hard for programmers to appreciate programming language features that aren't present in their own favorite language. Does the Sapir-Whorf hypothesis hold for computer languages? Peter Seibel, language lawyer (admitted, at various times, to the Perl, Java, and Common Lisp bars) and author of the award-winning book _Practical Common Lisp_, will discuss how our choices of programming language influences and shapes our pattern languages and the architectures we can, or are likely to, invent.
Interview on: The Vega Science Trust Fred Sanger is often considered the father of modern biology, and is one of the few people to have been awarded two Nobel prizes. Working in Cambridge he developed a new chromatographic method fo determining amino-acid end-groups. His new chromatographic results on the free amino groups of insulin were published in 1945 and the complete sequence of insulin in 1955.
Samuel Bogoch Replikins Ltd. Replikin genome sequences and survival rates in shrimp and human pandemics on: Replikins Ltd. Dr. Bogoch spoke at the World Aquaculture Conference in San Antonio, giving some background on his company's Replikins technology and announcing test results in conjunction with the University of Arizona. These results correlate virulence of four Taura virus strains in shrimp with the concentration of Replikin subsequences in the virus genomes. This is the first virus protein structure to have been shown to be quantitatively relate not only to the occurrence of epidemics, but now specifically to mortality rate of the host.
Jim Nickerson APCT Energy Crisis Management - new ultracapacitor technology on: Google TechTalks A new ultracapacitor technology from APCT (US-Ukrainian start-up) provides an efficient, low cost means of managing power delivery for applications ranging from hand held devices to hybrid vehicles and power generating systems of all types. When integrated into battery powered devices, the APCT technology can extend battery life by as much as 400%, lowering the cost of batteries and reducing hazardous waste streams.
Jane Goodall Jane Goodall Institute for Wildlife Research Jane Goodall speaks at Google on: Google Video In the summer of 1960, 26-year-old Jane Goodall arrived on the shore of Lake Tanganyika in East Africa to study the area's chimpanzee population. The trip meant the fulfillment of Jane Goodall's childhood dream. In 1977, Jane founded the Jane Goodall Institute for Wildlife Research, Education and Conservation to provide ongoing support for field research on wild chimpanzees. Today, the mission of the Jane Goodall Institute is to advance the power of individuals to take informed and compassionate action to improve the environment for all living things. The Institute is a leader in the effort to protect chimpanzees and their habitats and is widely recognized for establishing innovative community-centered conservation and development programs in Africa and the Roots & Shoots education program in more than 70 countries.
Timur Shaftan Brookhaven National Laboratory The NLS-II Project; 418th Brookhaven Lecture on: Brookhaven National Laboratory The NSLS-II project will establish a third-generation light source at Brookhaven Lab, increasing beam-line brightness by 10,000. Achieving and maintaining this will involve tightly focusing the electron beam, providing the most efficient insertion devices, and achieving and maintaining a high electron current. In this talk, the various sub-systems of NSLS-II will be reviewed, and the requirements and key elements of their design will be discussed. In addition, the a small prototype of a light source of a different kind that was developed by the NSLS will also be discussed.
Congjun Wu Kavli Institute for Theoretical Physics Exploring New States of Matter in the p-Orbital Bands of Optical Lattices on: Kavli Institute In this talk, we will present new features of orbital physics in the p-orbital bands with bosons and fermions, which are not usually realized in solid state systems. These include quantum stripe ordering of orbital angular momentum moments in the triangular lattice, Wigner crystallization of neutral atoms in the flat band of the honeycomb lattice, and frustrated superfluidity with time-reversal symmetry breaking in the double-well lattice. Signatures of these new states in the time of flight experiments will be discussed.

Barry Schwartz Swarthmore College The Paradox of Choice - Why More Is Less on: Google Video Barry Schwartz is a sociology professor at Swarthmore College and author of The Paradox of Choice. In this talk, he persuasively explains how and why the abundance of choice in modern society is actually making us miserable.
Daniela Maurer Binder The New CO2 incubators with hot air sterilization on: Biocompare Our CO2 incubators simulate natural conditions, where many perfect details make up the sum total. We also fuse together the details by amalgamating the growth parameters such as CO2, temperature and humidity into a finely tuned interaction that we call natural simulation. This is a process that we have developed and patented, unparalleled in our industry and the closest thing to natural conditions.
Genes, worms and the new genetics on: A Royal Society A surprising finding over the past 20 years is that all animals have many of the same genes and that they use them in similar ways to grow and develop. Now that we know the complete DNA sequences of several animals, we can see for example that 60% of genes in the small worm C elegans have a human counterpart. These similarities mean that much of what is learned about what genes do in simple animals such as worms can help us understand what human genes do. Using a remarkable new technique called RNA interference (RNAi), we can quickly test the function of individual genes. In this lecture Julie discussed how she has applied the RNAi technique to worm genes to ask for the first time what most of the genes in an animal do. Extending these approaches to other animals is speeding up the rate of biological discovery and understanding.
