        Science for the Public Sept 18,2012. Tom Mrowka, Professor of Mathematics and Gigliola Staffilani,Professor of Mathematics, (both) Massachusetts Institute of Technology. Professors Tom Mrowka and Gigliola Staffilani explain how an understanding of Nature inevitably depends on mathematics. Forces, processes, patterns —they are all expressed in the unique and universal language of mathematics, and particularly in geometry. These mathematicians decode for a general public the deep aesthetics of these structures, and they explain how mathematics reveals the core of Nature. No need to fear math —it is a whole new way to experience reality.s, (both) Massachusetts Institute of Technology.

          The Efficient and Effective Transmission, Storage, and Retrieval of Information on a Large-Scale are among the Core Technical Problems in the Modern Digital Revolution Anna Gilbert, University of Michigan Even areas of science and technology that traditionally generated and analyzed small ``analog'' data sets, such as biology, now routinely handle much larger, discrete data with sophisticated algorithmic processing and generation. The massive volume of data necessitates the quest for mathematical and algorithmic methods for efficiently describing, summarizing, synthesizing, and, increasingly more critical, deciding when and how to discard data before storing or transmitting it. The mathematical and algorithmic techniques used to describe data, to capture its inherent information, and to encode it for transmission and analysis are fundamentally different from those used in the analysis of small data sets. They include using randomness to take random snapshots of data sets and running algorithms whose success is only approximate and correct with high probability. I will discuss several of these techniques, what implications they have for scientific analysis, and how these techniques are changing not only how scientists collect data but the devices with which they measure physical or biological phenomena.

            Sensors, Networks, and Massive Data Michael W. Mahoney, Department of Mathematics, Stanford University Massive quantities of data are routinely generated in many scientific and non-scientific domains, and developing tools to deal with these data leads to very fundamental algorithmic and statistical challenges. At root, these data are generated in such quantities because technological developments permit us to measure or monitor or sense the world very inexpensively at unprecedented levels of granularity; and, relatedly, a common theme in many of these applications is that, since the data are generated in relatively-uncontrolled ways, "noise" is often a dominant property of the data, with interesting "signal" being a second order effect. A good "hydrogen atom" for addressing these issues and for developing algorithmic and statistical methods for massive data more generally can be found in large social and information networks, basically since nearly any "niceness" assumption, e.g., about how the data are generated or structured, is severely violated. Using this as a case study, I will describe some of the challenges that scientists will face as they deal more and more with increasingly massive data.

              Big Data Science: The Algorithmic Advances that Lie Underneath Alexander Gray, Georgia Institute of Technology Virtually every area of science and engineering is either experiencing its own version of a "big data" revolution that is yielding unprecedented new insights, or has such opportunities on the horizon. I will survey seven main types of data analysis methods that can be used across all areas, and give examples in astrophysics of new science that can be achieved by applying such methods to massive data sources. The central difficulty is in the computation of such analyses. I'll discuss seven main types of computational bottlenecks and how difficult they are, as well as seven main types of algorithmic concepts that can be used to tackle them, drawing from the fastest practical algorithms across many areas of applied mathematics and computer science.

                      Tags

                      Tags are keywords that describe videos. For example, a video of your Hawaiian vacation might be tagged with "Hawaii," "beach," "surfing," and "sunburn."
