I. Edward Block, a founder and longtime managing director of SIAM, died on February 18 at the age of 90. From 1952, when SIAM was officially incorporated, through 1976, the beginning of his full-time employment at SIAM, until his retirement in the fall of 1994, Ed had a hand in every aspect of every step of SIAM’s development and growing presence in the international mathematical sciences community. It was no accident that he chose the title “managing director.”

A SIAM President Remembers I.E. Block

I was very involved with SIAM, and its meetings, publications, and promotion of applied mathematics, from my earliest postdoctoral appointment in 1966 through serving as president in 1990–91. SIAM had great leaders, including presidents Dick DiPrima (1979–80), Hirsh Cohen (1983–84), Ivar Stakgold (1989–90), and Avner Friedman (1993–94), among many others, before and since. But it was Ed Block who year after year worked harder than anyone else developing an unending sequence of journals, meetings, book series, activity groups, and international collaborations.

Protecting an Ecosystem as  Ocean Levels Rise

By Hans Kaper
Our planet is being stressed. For some 150 years, we have run an uncontrolled experiment, assuming (wrongly) that our resources are infinite and that nature will adjust to our needs and desires. As a result, our climate is changing, ocean levels are rising, and the impact of natural disasters has been increasing. As mathematical and computational scientists, we should be concerned: We have a responsibility. The only tools available for studying future scenarios are mathematical models and computational experiments; large-scale controlled experiments are essentially impossible, and there is no planet B. The newly formed SIAM Activity Group on Mathematics of Planet Earth (see announcement on page 4) is SIAM’s forum for discussions of mathematical and computational issues of climate, sustainability, ecology, socioeconomic systems, and the environment.1

The Structure and Evolution of  the Next-generation Electric Grid

By John Guckenheimer

The electric power grid is a quintessential complex system, one whose complexity continues to grow. This article briefly describes the structure and evolution of the grid, a few of the recent ongoing changes, and some of the problems described at a workshop sponsored by the National Academies Committee on Analytic Foundations of the Next Generation Electric Grid (see sidebar below), in Irvine, California, February 11–13, 2015.*

Maria Klawe's Mighty Blow for Women

By Paul Davis
Few technological types missed the story of long-time SIAM member Maria Klawe’s pushback while interviewing Microsoft CEO Satya Nadella last October at the Grace Hopper Celebration of Women in Computing. In response to Klawe’s query about women seeking raises, he replied, “It’s not really about asking for the raise, but knowing and having faith that the system will actually give you the right raises as you go along. . . . That, I think, might be one of the additional superpowers that, quite frankly, women who don’t ask for a raise have. Because that’s good karma.” To applause from the audience, Klawe parried, “This is one of the very few things I disagree with you on.”1

How Can the SIAM Community Help Embed  Math Modeling in K–16 Curricula?

By Rachel Levy, Kara Maki, Kathleen Fowler
SIAM has a vital role to play in supporting the integration of mathematical modeling into K–16 education. Current efforts led by SIAM members demonstrate that students can experience mathematical modeling and industrial mathematics in many contexts: school coursework and projects; summer, weekend, and after-school camps; and, at the undergraduate level, internships and capstone experiences. The SIAM Committee on Education, which plans to pilot new ideas in coordination with the new SIAM Activity Group on Applied Mathematics Education, would like to hear from readers about related efforts.

Kelvin’s Circulation Theorem  and an Isoperimetric Inequality

By Mark Levi
Kelvin’s theorem in two dimensions states that the vorticity (the curl of the velocity field) in an inviscid incompressible fluid is transported by the fluid––that is, it remains constant along the trajectories of the fluid particles. The following intuitive explanation, I think, shows what’s really going on.

The Big Data paradigm has emerged as a result of the vast amounts of data that are becoming available across science, business, and government. Realizing the potential of big data will require fundamentally new techniques and technologies to handle the complexity, size, and rate of generation of these data. Principled, innovative approaches are needed to address the challenges associated with the management, modeling, and analysis of such unprecedented amounts of data, including automation of aspects of the data-enabled discovery processes, development of new computational, mathematical, and statistical methods for data analysis, and creation of novel visualization techniques for drawing insights from data.

The SIAM Council and Board of Trustees have approved the SIAM Activity Group on Mathematics of Planet Earth. SIAG/MPE ( will focus on planet Earth, its life-supporting capacity, and the impact of human activities on it. It will provide a forum for discussions of mathematical and computational issues of climate, sustainability, ecology, socio-economic systems, and the environment. Activities will include a biennial SIAM Conference on Mathematics of Planet Earth (with the first to take place in the fall of 2016), and minisymposia at SIAM Annual Meetings and other conferences.
