Extractions: HOME PEOPLE UNDERGRADUATE GRADUATE ... History When I arrived at the University of Maryland in 1957, it was one of the most important centers for partial differential equations in the whole world. Most of the activity took place in the Institute for Fluid Dynamics and Applied Mathematics, which was situated on the third floor of the present Mathematics Building, while the Department of Mathematics occupied the first and the second floor. The fourth floor is a later addition. Many of the mathematicians at the Institute had a joint appointment in the Department, and did teach a course. Some, who originally came to the Institute, switched to the Department. Two of those are still with us, though both are emeriti now. One of them, Karl Stellmacher, gave a negative solution to a celebrated problem of Hadamard whether the only partial differential operators which exhibit Huygens' phenomenon are those which can be obtained by a change of variables from the wave operator. Among Avron Douglis' numerous publications, there is one written in collaboration with Shmuel Agmon and Louis Nirenberg which is one of the most often quoted papers in the history of mathematics. The first generation of member of the Institute was recruited by Monroe Martin, it first director, and by Alexander Weinstein, who has outstanding contributions to eigenvalues and to singular partial differential operators. Unfortunately Weinstein had a difficult personality, and some of those who came because of him, left because of him.

Extractions: MEDALLAS FIELDS "TRANSIRE SVVM PECTUS MVNDOQUE POTIRE" "Sobrepasar su propio entendimiento y apoderarse del mundo" Como un claro respaldo al estudio de las matemáticas en China, por primera vez en sus 105 años de historia, el XXIV congreso mundial de matemáticos, se ha celebrado en un país en vías de desarrollo. El evento comenzó, como es habitual, con la entrega de las medallas Fields, consideradas el premio Nobel de las matemáticas . El galardón, que se concede cada cuatro años, ha sido para el investigador francés Laurent Lafforgue y el ruso Vladimir Voevodsky Lafforgue, profesor del Instituto de Altos Estudios Científicos de París, trabaja en el programa Langlands, un concepto que busca una unidad subyacente entre varias disciplinas matemáticas. Vladimir Voevodsky, de origen ruso, es especialista en geometría algebraica abstracta. La medalla Fields, que sólo puede concederse a personas menores de 40 años, está acuñada en oro y lleva grabado en su anverso el siguiente lema: "Congregati ex toto orbe mathematici ob scriptia insignia tribuere" ("Los matemáticos de todo el mundo aquí reunidos rinden tributo por un trabajo extraordinario").

Extractions: Fields Procede el nombre de John Charles Fields (1863-1932), que en 1924 Presidió el Congreso Internacional de Matemáticas, en el cual se hizo la propuesta de concesión a los descubrimientos matemáticos más destacados. Se otorga el premio cada 4 años, y en total pueden recibir la medalla Fields hasta seis matemáticos en cada edición del mismo. Los galardonados han de ser menores de 40 años de edad. Aunque en algunas ocasiones se han concedido hasta un total de cuatro medallas Fields, en la última ocasión, agosto de 2002, solo han sido premiados dos de los posibles candidatos de todo el mundo. Han sido el ruso Vladimir Voevodsky y el francés Laurent Lafforgue. En lo que respecta a la cuantía económica, digamos que es irrisoria comparada con la de los Premios Nobel.

Extractions: Warning issued on November 18, 1992 Some 1,700 of the world's leading scientists, including the majority of Nobel laureates in the sciences, issued this appeal in November 1992. The Warning was written and spearheaded by UCS Chair Henry Kendall. Human beings and the natural world are on a collision course. Human activities inflict harsh and often irreversible damage on the environment and on critical resources. If not checked, many of our current practices put at serious risk the future that we wish for human society and the plant and animal kingdoms, and may so alter the living world that it will be unable to sustain life in the manner that we know. Fundamental changes are urgent if we are to avoid the collision our present course will bring about. The environment is suffering critical stress: The Atmosphere Stratospheric ozone depletion threatens us with enhanced ultraviolet radiation at the earth's surface, which can be damaging or lethal to many life forms. Air pollution near ground level, and acid precipitation, are already causing widespread injury to humans, forests and crops. Water Resources Heedless exploitation of depletable ground water supplies endangers food production and other essential human systems. Heavy demands on the world's surface waters have resulted in serious shortages in some 80 countries, containing 40% of the world's population. Pollution of rivers, lakes and ground water further limits the supply.
Extractions: The author, best known as an economics correspondent for The New York Times, describes her biography of John Nash as a play in three acts: genius, madness, and reawakening. It is hard to say exactly when, during the 1950s, it became clear that Nash was a rare genius. He began the decade as a promising graduate student at Princeton and ended it in madness. In the interim, he did the work he will always be remembered for, in game theory, geometry, and analysis. His reawakening from madness is no easier to date than his descent into it but seems to have been well under way by 1990, according to those who saw him on a more or less daily basis in and around Princeton. He spent the intervening decades in varying degrees of mental illness, the depths of which Nasar strives mightily to plumb. The book devotes only a chapter to Nash's boyhood in Bluefield, West Virginia, and another to his undergraduate years at the Carnegie Institute of Technology-now Carnegie Mellon University-which he attended on a Westinghouse scholarship between June 1945 and June 1948.* Nash arrived well prepared, having completed numerous courses at Bluefield College while still in high school. His friends from those years remember him as a "brain," destined to become a "scientist," presumably of the white-coated Hollywood variety then making relentlessly pub-licized contributions to the war effort. He excelled in school but displayed no particular affinity for any one subject. Socially, he is remembered as awkward and immature.

Extractions: John von Neumann, left, with Robert Oppenheimer, Director of the Institute for Advanced Study from 1947-66. In 1946, John von Neumann organized a group to develop and construct at the Institute a large-scale, high-speed electronic computing instrument which could be used as a new tool for the mathematician, wrote Robert Oppenheimer in an Institute for Advanced Study publication entitled Report of the Director, 1948-1953. The group undertook an engineering research and development program, Oppenheimer continued, which culminated in January, 1952 with the completion of a machine. This machine was the prototype for a number built by various government agencies. It has also contributed ideas to a number of other groups which have produced comparable instruments. John von Neumann was a Faculty member in the School of Mathematics from 1933-57. The logical architecture of the IAS computer, documented in a series of progress reports published by the Institute at every stage of its development, remains the prototype for nearly all computers in use today. VLADIMIR VOEVODSKY APPOINTED TO FACULTY IN SCHOOL OF MATHEMATICS The Institute for Advanced Study has announced the appointment of Vladimir Voevodsky as a Professor in the School of Mathematics.

On pseudo-differential operators and Fourier integral operators. This will be a lecture, not a technical talk. Basically, I will try to present the basic ideas of pseudo-differential operators and fourier integral operators (PsiDOs and FIOs), as far as can be done in one hour. Usually, books on the subject tend to be thick (like Treves' two volumes). So, in one hour, there isn't much one can do (Fefferman, last semester, spent two months talking about it to the math grad students and he didn't do much, either...). My goal is not show you that I was able to learn a lot of hard non-trivial theorems, which you won't be the least interested in. I actually want you to get the general idea of the subject in very general and simple terms. PsiDOs and FIO are harmonic analysis tools, invented in the mid sixties by J.J.Kohn (yes... the one upstairs), Louis Niremberg and Lars Hormander, to help answer questions about the regularity of solutions to linear PDEs with non constant coefficients.
