Gordon Moore Intel General Session Speaker, Gordon Moore. Seminar Day 2002 on: Caltech In his talk, Moore examined the development of the powerful technology underlying the semi-conductor industry, and attempts to explain why, counter-intuitively, electronic equipment gets cheaper as it gets more complex.
Everyday Science: The science in your lunch on: sciencelive Food is really important to all of us, but what is it? Why does cooking change it? Find out how temperature affects eggs and jelly and why chocolate goes white when it's been sitting around for too long. At the end of it all though, food is fuel. It contains lots of stored energy which, if you choose, can be released in an explosion...
How to Survive a Robot Uprising' - Daniel H. Wilson speaks at Google on: Google Video Daniel H. Wilson discusses his book 'How to Survive a Robot Uprising: Tips On Defending Yourself Against the Coming Rebellion'. This video is part of the Google Author Series - filmed at Google headquarters in Mountain View, CA and is part of the Authors@Google series.
Mike Davis: Planet of Slums (interview) 1of3 on: YouTube Davis provides the first global overview of the diverse religious, ethnic, and political movements competing for the souls of the new urban poor. He surveys Hindu fundamentalism in Bombay, the Islamist resistance in Casablanca and Cairo, street gangs in Cape Town and San Salvador, Pentecostalism in Kinshasa and Rio de Janeiro, and revolutionary populism in Caracas and La Paz. Planet of Slums ends with a provocative meditation on the 'war on terrorism' as an incipient world war between the American empire and the slum poor. 'In this trenchantly argued book, Mike Davis quantifies the nightmarish mass production of slums that marks the contemporary city. With cool indignation, Davis argues that the exponential growth of slums is no accident but the result of a perfect storm of corrupt leadership, institutional failure, and IMF-imposed Structural Adjustment Programs leading to a massive transfer of wealth from poor to rich.
Dean Ornish Preventative Medicine Research Institute Global trends on: TEDtalks In this 3-minute talk, Dr. Dean Ornish tracks the dramatic rise of obesity, diabetes and cardiovascular disease across the globe -- as the world begins to eat, live and die like we do in the U.S. (Recorded February 2006 in Monterey, CA. Duration: 3:34)
Diet and Cardiovascular Disease on: sciencelive Charlotte speaks to Caroline Furnis about food and cardiovascular disease. She talked about phytochemicals in vegetables, how to eat a healthier diet and also brought in an experiment to demonstrate how to find out how much vitamin C was contained in fruit. Caroline works for the Institute of Food Research here in Norwhich.
Barton Zweibach MIT String Theory for Pedestrians Part II on: CERN 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. Then I will turn to the quantum theory and discuss applications to the investigation of hadronic spectra and the recently discovered quark-gluon plasma. I will conclude with a sketch of string models of particle physics and showing some avenues that may lead to a complete formulation of string theory.
The Cray-1 Supercomputer: 30th Anniversary Event-Celebrating the Man and the Machine on: In 1976, Cray Research, Inc. delivered its first supercomputer to the Los Alamos National Laboratory, birthplace of the atomic bomb. The Cray-1, as it was known, was the fastest computer in the world and was a blend of Cray's unique engineering style and an urgency for high performance computing borne of cold war competition between the United States and the Soviet Union.
Barry Barish California Institute of Technology Catching the Waves with LIGO on: Caltech Dr. Barry Barish, the Ronald and Maxine Linde Professor of Physics and director of the Laser Interferometer Gravitational-Wave Observatory (LIGO) Laboratory at Caltech, presented the LIGO project that is being developed to detect gravitational waves that Einstein predicted the existence of in 1916 as a consequence of the general theory of relativity.
James Lindholm Stellwagen Sanctuary Going Deeper: New Marine Technologies on: WBGH The exploration and the study of the marine environment presents numerous challenges, particularly in the northwest Atlantic where Stellwagen Bank National Marine Sanctuary is located.
Benchmarking parameter estimation and reverse engineering strategies on: videolectures.net Parameter estimation has become a central problem in systems biology, both in the form of calibration of bottom-up models or as a component of reverse engineering algorithms. With a proliferation of algorithms proposed for these purposes it has become important to compare them in objective ways. I will argue that in silico biochemical network models are extremely useful for this purpose. Several networks will be presented that are challenging tests for parameter estimation and network inference. An issue that arises from the use of in silico networks, though, is whether they can provide realistic data. The application of this benchmarking methodology will be illustrated with a comparison of four reverse engineering methods.
Sarah Heilshorn California Institute of Technology Protein Engineering: A Novel Approach to Creating New Biomaterials on: Caltech Sarah Heilshorn is a graduate student in chemistry and chemical engineering at Caltech. Cardiovascular disease is a leading cause of death in industrialized nations. Currently, the most commonly used materials for synthetic, arterial bypasses do not support cell growth, and often fail within three years of being implanted. In response, protein engineering is being used to design an optimum replacement biomaterial.
Tierney Thys Marine biologist Swim with gaint sunfish in the open ocean on: TedTalks Marine biologist Tierney Thys asks the audience to step into the open ocean, for a visit to the world of the Mola mola, or giant ocean sunfish. Basking, eating jellyfish, and getting massages, this behemoth offers clues to life in the open ocean -- which accounts for 90 percent of the living space on this planet -- and also shows how climate change may be affecting all life.
Martino Barenco Institute of Child Health Dynamic Modelling of Microarray Data on: We recently released rHVDM (Hidden Variable Dynamic Modelling), an R/Bioconductor package that predicts targets of a known transcription factor using time course microarray data. The key feature behind the algorithm is a simple ODE model of mRNA concentration. In the first stage of rHVDM, transcription factor activity (the hidden variable) is deduced from the expression time profile of a small number of known targets.
Matthias Seeger Max Planck Institute Experimental Design for Efficient Indentification of Gene Regulatory Networks using Sparse Bayesian Models on: Identifying large gene regulatory networks is an important task, while the acquisition of data through perturbation experiments (e.g., gene switches, RNAi) is expensive. It is thus desirable to use an identification method that effectively incorporates available prior knowledge --- such as sparse connectivity --- and that allows to design experiments such that maximal information is gained from each one. Our main contributions are twofold: a method for consistent inference of network structure is provided, incorporating prior knowledge about sparse connectivity.
Inktomi's Wild Ride: A Personal View of the Internet Bubble on: The Inktomi story is about a technology company on one of the wildest rides in the wildest era in the history of technology. After fast growth to the rare state of profitability, Inktomi joined the Nasdaq 100 as a representative of the Internet. Despite having real value, Inktomi was pulled down -- not by the dot coms -- but by the collapse of the telecom sector (including Worldcom and Enron). In this talk, Inktomi co-founder, Dr. Eric Brewer, covers the fascinating history of Inktomi, and gives an up close and personal view of what the Internet bubble meant -- both on the way up and on the way down. He shares his views on the Internet and on what a rational leader must do in an irrationally exuberant environment.
