Snowball Earth pioneer honoured

27.01.2009
The Geological Society’s oldest and most prestigious award, the Wollaston Medal, has been awarded to Paul F. Hoffman, one of the major proponents of the controversial “Snowball Earth” theory.

This theory suggests that in its early history the Earth suffered glaciations so major that it froze over completely. It remains controversial, but has proved extremely fruitful for our understanding of how the Earth system functioned many hundreds of millions of years ago.

In a 1998 paper, Hoffman proposed that a drop in the level of carbon dioxide in the atmosphere 750 million years ago caused a global fall in temperature that very nearly wiped out all life on Earth. Hoffman’s most significant impact on Earth science has arisen from his development of holistic models of geological processes during the Precambrian (c. 4500 – 542 million years ago). The scope of this subsequent work shows a remarkable interdisciplinary understanding, and stands as an exemplary model of how Earth science research should be conducted.

The Wollaston Medal (named for William Hyde Wollaston 1766-1828, the discoverer of the element Palladium, in which the medal is struck) was first awarded in 1831 to William Smith, known as “the father of English Geology”, who is credited with creating the first geological map of Britain. It was bestowed on Charles Darwin in 1859 - the same year in which On the Origin of Species was published. The award, made some months earlier, was given in recognition of Darwin’s “judicious and vigorous efforts on some of the harder problems of geology”.

Past recipients of the Wollaston also include Richard Owen, founder of the Natural History Museum in London; William Buckland, who published the first full description of what would later become known as the dinosaur, and Charles Lyell.

In addition to the Wollaston medal, the society made the following awards for 2009.

•Wollaston Medal - Prof. Paul Hoffman (Harvard University)
•Lyell Medal – Prof. Ian Nicholas McCave (Cambridge University)
•Murchison Medal – Prof. David Kohlstedt (University of Illinois)
•William Smith Medal – Prof. Michael J Russell (NASA; JPL)
•Coke Medal – Prof. Bruce Yardley (Leeds University)
•Coke Medal – Prof. Jane Plant (Imperial College, London)
•Bigsby Medal – Prof. Christian Turney (University of Exeter)
•Sue Tyler Friedman – Prof. Philippe Taquet
•R H Worth Prize – Dr Robert Antony Bryn Bazley
•William Smith Fund – Dr David Selby (University of Durham)
•Lyell Fund - Professor Colm ÓCofaigh (University of Durham)
•Murchison Fund – Dr Howard Falcon-Lang (University of Bristol)
•Distinguished Service Award – Dr Stuart Monro (Dynamic Earth)
The 2009 Awards will also include two President’s Awards, which will be announced later in the year. The Awards will be presented at President’s Day 2009, at Burlington House on June 3.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
