Nobel Prize Laureate Steven Chu speaks at ETH Zurich (Richard R. Ernst Lecture 2015)

source: ETH Zürich     2015年3月16日
Steven Chu, the American winner of the Nobel Prize in Physics who was US Secretary of Energy between 2009 and 2013,delivered the 2015 Richard R. Ernst lecture at ETH Zurich. He discussed his vision for an economy based on sustainable sources of energy.
The Richard R. Ernst Lecture is held annually in honour of the 1991 Nobel Laureate in Chemistry and is organised by ETH Zurich’s Laboratory of Physical Chemistry. The lecture aims to promote an interchange between research and the public and to raise awareness of future key issues. The Richard R. Ernst Medal is presented to outstanding individuals who have made a valuable contribution to society and science. Previous recipients of the award include: Gottfried Schatz, Kofi Annan, Ernst Ludwig Winnacker, Roger Penrose, Ahmed Zewail and Kâmil Uğurbil.

Professor Dr. Sir Roger Penrose is Emeritus Rouse Ball Professor of Mathematics at the University of Oxford and has received numerous prizes and awards, among them the 1988 Wolf Prize for Physics, which he shared with Stephen Hawking for their joint contribution to our understanding of the universe. Prof. Sir Penrose has also written several books for the public, including 'The Emperor's New Mind' and most recently 'Cycles of Time'.
The lecture was hold on 4 April 2012 at ETH Zurich, when Roger Penrose was awarded the Richard R. Ernst Medal.

Professor Avi Wigderson on a computational theory of randomness

Avi Wigderson is a professor of Mathematics at the Institute for Advanced Study in Princeton. After studying Computer Science at Technion in Haifa, he obtained his PhD in 1983 from Princeton University. He held then various visiting positions including IBM Research at San Jose, MSRI Berkeley, and IAS Princeton. From 1986 to 2003 he was associate professor at the Hebrew University in Jerusalem. Wigderson has been for two decades a leading figure in the field of Mathematics of Computer Science, with fundamental contributions, in particular in Complexity Theory, Randomness, and Cryptography. He has been invited speaker at ICM in Tokyo (1990), and Zurich (1994), and plenary speaker in Madrid (2006). Among many awards he received both the Nevanlinna Prize (1994), and the Gödel Prize (2009).
This lecture about a computational theory of randomness was hold on 10 May 2012 at ETH Zurich, when Avi Wigderson was invited as guest speaker of the Wolfgang Pauli Lectures. The Wolfgang Pauli Lectures are an annual lecture series that is devoted alternately to physics, mathematics and biology. They are named after the great theoretical physicist and Nobel laureate Wolfgang Pauli, who was professor at ETH Zurich from 1928 until his death in 1958.

Pauli Lectures 2015: Mathematicians helping Art Historians and Art Conservators

source: ETH Zürich    2015年10月29日
In recent years, mathematical algorithms have helped art historians and art conservators putting together the thousands of fragments into which an unfortunate WWII bombing destroyed world famous frescos by Mantegna, decide that certain paintings by masters were “roll mates” (their canvases were cut from the same bolt), virtually remove artifacts in preparation for a restoration campaign, get more insight into paintings hidden underneath a visible one.
The presentation given by Prof. Ingrid Daubechies, Duke University, Durham, USA, reviews these applications, and give a glimpse into the mathematical aspects that make this possible.

Pauli Lectures 2015: Bones, Teeth and Animation

source: ETH Zürich    2015年11月13日
The talk given by Prof. Ingrid Daubechies, Duke University, Durham, USA, presents mathematical explorations motivated by the need of biological morphologists to compare different phenotypical structures. At present, scientists using physical traits to study evolutionary relationships among living and extinct animals analyze data extracted from carefully defined anatomical correspondence points (landmarks). Identifying and recording these landmarks is time consuming and can be done accurately only by trained morphologists. This necessity renders these studies inaccessible to non-morphologists and causes phenomics to lag behind genomics in elucidating evolutionary patterns.

Unlike other algorithms presented for morphological correspondences, the approach presented in the talk does not require any preliminary marking of special features or landmarks by the user. It also differs from other seminal work in computational geometry in that the algorithms are polynomial in nature and thus faster, making pairwise comparisons feasible for significantly larger numbers of digitized surfaces.
This approach has already been used by biologists to obtain new results.

Via internet we can download images from all over the world. Most of these are compressed in some way, to make the transmission and storage more efficient. Mathematics plays an important role in these compression techniques, which Prof. Ingrid Daubechies, Duke University, Durham, USA explores in her lecture.

The Wolfgang Pauli Lectures 2016 are dedicated to Biology. Prof. James E. Rothman, Yale University, New Haven, USA (2013 Nobel Prize in Physiology or Medicine) is renowned for discovering the molecular machinery responsible for transfer of materials among compartments within cells. In so doing, Rothman provided a unified conceptual framework for understanding such diverse and important processes as the release of insulin into the blood, communication between nerve cells in the brain, and the entry of viruses to infect cells.
