Saul Perlmutter Receives Nobel Prize in Physics 27 October 2011
Saul Perlmutter receives Nobel Prize in physics 27 October 2011 wonderful that the Nobel Prize is being awarded for results which reflect humanity's long quest to understand our world and how we got here. The ideas and discoveries that led to our ability to measure the expansion history of the universe have a truly international heritage, with key contributions from almost every continent and culture. And quite appropriately, our result - the acceleration of the universe - was the product of two teams of scientists from around the world. These are the kinds of discoveries that the whole world can feel a part of and celebrate, as humanity advances its knowledge of our universe." Saul Perlmutter addresses reporters and Berkeley Lab "I offer my congratulations to Dr. Perlmutter and the staff at a press conference on the morning of October 4 entire Berkeley Lab team for their extraordinary following the announcement of his Nobel Prize in contributions to science, which are being Physics. Credit: Roy Kaltschmidt, Lawrence Berkeley recognized with the 2011 Nobel Prize in Physics," National Laboratory said Energy Secretary Steven Chu, former director of Berkeley Lab and himself a winner of the Nobel Prize in Physics in 1997. "His groundbreaking work showed us that the expansion of the universe is Saul Perlmutter, an astrophysicist at the U.S. actually speeding up rather than slowing down. Dr. Department of Energy's Lawrence Berkeley Perlmutter's award is another reminder of the National Laboratory and a professor of physics at incredible talent and world-leading expertise the University of California at Berkeley, has won America has at our National Laboratories. -
Research/Teaching Statement Gerard Awanou 1 Trivariate Splines
Research/Teaching statement Gerard Awanou I would like to describe in this statement the research I have done and comment on future directions. My work has been on trivariate splines for scattered data in- terpolation and numerical solution of partial differential equations, particularly, the Navier-Stokes equations. Another line of my research is mathematical finance. I have been interested in risk minimization in regime switching and two factor stochastic volatility models. I will describe my recent success in the construction of a family of mixed elements for three dimensional elasticity, a problem which was open for over 40 years. 1 Trivariate splines Let us assume that Ω is a three dimensional domain with a triangulation 4, i.e. the union of nonoverlapping tetrahedra with the property that the intersection of any two tetrahedra is either empty, a common vertex, a common edge or a common face. A spline function of degree d and smoothness r over Ω is a r times differentiable func- tion which is a polynomial of degree d when restricted to each tetrahedron. Finite elements are examples of spline functions. Scattered data interpolation A typical problem in surface design is the following: Given a set of scattered points in IR3, which are assumed to be at the vertices of a triangulation 4, find a spline with appropriate smoothness which interpolates the given data at the vertices. The resolution of this problem is by means of the construction of locally supported spline functions with high smoothness. I have implemented C1 spline functions in [6] on a special triangulation. -

Ripples in Spacetime
editorial Ripples in spacetime The 2017 Nobel prize in Physics has been awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne “for decisive contributions to the LIGO detector and the observation of gravitational waves”. It is, frankly, difficult to find something original to say about the detection of gravitational waves that hasn’t been said already. The technological feat of measuring fluctuations in the fabric of spacetime less than one-thousandth the width of an atomic nucleus is quite simply astonishing. The scientific achievement represented by the confirmation of a century-old prediction by Albert Einstein is unique. And the collaborative effort that made the discovery possible — the Laser Interferometer Gravitational-Wave Observatory (LIGO) — is inspiring. Adapted from Phys. Rev. Lett. 116, 061102 (2016), under Creative Commons Licence. Rainer Weiss and Kip Thorne were, along with the late Ronald Drever, founders of the project that eventually became known Barry Barish, who was the director Last month we received a spectacular as LIGO. In the 1960s, Thorne, a black hole of LIGO from 1997 to 2005, is widely demonstration that talk of a new era expert, had come to believe that his objects of credited with transforming it into a ‘big of gravitational astronomy was no interest should be detectable as gravitational physics’ collaboration, and providing the exaggeration. Cued by detections at LIGO waves. Separately, and inspired by previous organizational structure required to ensure and Virgo, an interferometer based in Pisa, proposals, Weiss came up with the first it worked. Of course, the passion, skill and Italy, more than 70 teams of researchers calculations detailing how an interferometer dedication of the thousand or so scientists working at different telescopes around could be used to detect them in 1972. -

Luis Alvarez: the Ideas Man
CERN Courier March 2012 Commemoration Luis Alvarez: the ideas man The years from the early 1950s to the late 1980s came alive again during a symposium to commemorate the birth of one of the great scientists and inventors of the 20th century. Luis Alvarez – one of the greatest experimental physicists of the 20th century – combined the interests of a scientist, an inventor, a detective and an explorer. He left his mark on areas that ranged from radar through to cosmic rays, nuclear physics, particle accel- erators, detectors and large-scale data analysis, as well as particles and astrophysics. On 19 November, some 200 people gathered at Berkeley to commemorate the 100th anniversary of his birth. Alumni of the Alvarez group – among them physicists, engineers, programmers and bubble-chamber film scanners – were joined by his collaborators, family, present-day students and admirers, as well as scientists whose professional lineage traces back to him. Hosted by the Lawrence Berkeley National Laboratory (LBNL) and the University of California at Berkeley, the symposium reviewed his long career and lasting legacy. A recurring theme of the symposium was, as one speaker put it, a “Shakespeare-type dilemma”: how could one person have accom- plished all of that in one lifetime? Beyond his own initiatives, Alvarez created a culture around him that inspired others to, as George Smoot put it, “think big,” as well as to “think broadly and then deep” and to take risks. Combined with Alvarez’s strong scientific standards and great care in execut- ing them, these principles led directly to the awarding of two Nobel Luis Alvarez celebrating the announcement of his 1968 Nobel prizes in physics to scientists at Berkeley – George Smoot in 2006 prize. -

Recent Observations of Gravitational Waves by LIGO and Virgo Detectors
universe Review Recent Observations of Gravitational Waves by LIGO and Virgo Detectors Andrzej Królak 1,2,* and Paritosh Verma 2 1 Institute of Mathematics, Polish Academy of Sciences, 00-656 Warsaw, Poland 2 National Centre for Nuclear Research, 05-400 Otwock, Poland; [email protected] * Correspondence: [email protected] Abstract: In this paper we present the most recent observations of gravitational waves (GWs) by LIGO and Virgo detectors. We also discuss contributions of the recent Nobel prize winner, Sir Roger Penrose to understanding gravitational radiation and black holes (BHs). We make a short introduction to GW phenomenon in general relativity (GR) and we present main sources of detectable GW signals. We describe the laser interferometric detectors that made the first observations of GWs. We briefly discuss the first direct detection of GW signal that originated from a merger of two BHs and the first detection of GW signal form merger of two neutron stars (NSs). Finally we present in more detail the observations of GW signals made during the first half of the most recent observing run of the LIGO and Virgo projects. Finally we present prospects for future GW observations. Keywords: gravitational waves; black holes; neutron stars; laser interferometers 1. Introduction The first terrestrial direct detection of GWs on 14 September 2015, was a milestone Citation: Kro´lak, A.; Verma, P. discovery, and it opened up an entirely new window to explore the universe.
