Attending the APS March Meeting 2021

Guest post by Andrea Richaud, recipient of the Communications Physics 2020 Early Career Researcher grant which enabled him to attend a conference or scientific school of his choice.

In December 2020, I had the pleasure to receive the 2020 Training Grant for Early Career Researchers from the journal Communications Physics. After defending my doctoral thesis in February 2020, I joined SISSA (International School for Advanced Studies, Trieste, Italy), where I am now post-doctoral researcher in the Condensed Matter section.  The focus of my research is on SU(N) fermionic systems, their possible topological phases, and their possible use as quantum simulators of multiband solid-state models. This is an active research field, as ultracold-atom-based platforms illuminate the intimate physics of strongly-correlated systems, by getting rid of a number of spurious effects (like crystal defects) which are inevitably present in standard solid-state systems.

As an awardee of the ECR training grant, I decided to attend the APS March Meeting 2021, a very important conference which involved more than 11,000 different researchers from all over the world. Despite its virtual form (due to the persistent pandemic situation), attending this conference was a very positive and stimulating experience, as I had the possibility to watch tens of very interesting seminars encompassing several aspects of my current research activity. In particular, I found it useful to attend seminars focusing on experimental aspects of the topics which I investigate at the theoretical level. Even as a theoretician, I think that being up to date with experimental advances is really crucial, as one can get valuable ideas and correctly interpret the open problems.

In spite of the virtual form of the conference, I managed to have a good interaction with many speakers, asking them questions and sharing ideas about common research topics. This was possible thanks to the presence of “Zoom networking rooms”, which were made available at the end of each session. Of course, they could not fully replace a good traditional coffee break, but l think that they worked well enough for this pandemic situation.  Among the advantages of attending such a large meeting virtually, the online platform made switching between rooms pretty easy (compared to running down corridors in a conference centre) and every seminar was recorded and made available to the attendees to re-watch. I am very grateful to the journal Nature Communications Physics for awarding me the prize which allowed me to take part to the APS March Meeting 2021. I definitely think that this experience has been very beneficial for my career as a young researcher.

Hawking Hawking: author Charles Seife on how he cracked the cosmologist’s myth

The British cosmologist Stephen Hawking (1942–2018) was probably the most recognizable scientist of the last 50 years. Many of his greatest contributions were in the study of black holes. In particular, he discovered in 1974 that black holes emit what came to be known as Hawking radiation — which shows that black holes are not truly black and appears to contradict quantum mechanics.

His public persona was forged by his popularization work, beginning with the wildly successful 1988 book A Brief History of Time and his appearances on television shows such as Star Trek: The Next Generation and The Big Bang Theory. Later, he was the subject of the 2014 biographical film A Theory of Everything.

Part of the public’s fascination with Hawking lay in his stoicism in the face of adversity. When he was 21, he was diagnosed with amyotrophic lateral sclerosis, and his doctors gave him two years to live. In the later decades of his life, he was almost completely paralyzed and spoke through a voice synthesizer, which became part of his mystique.

In the media, Hawking was often portrayed as a genius on a par with Albert Einstein or Isaac Newton, but it was an exaggeration that Hawking himself often resisted to. With his new biography, Hawking Hawking: The selling of a scientific celebrity (Basic Book, New York, US$30.00), Charles Seife wants to set the record straight.

Seife is a professor of Journalism at New York University and the author of six previous books. He has covered Hawking the researcher during his year as a reporter for Science.

Davide Castelvecchi, reporter from Nature, interviewed Seife to go behind the scenes. The following was edited for length and clarity.

What motivated you to write this book? 

I never thought of myself as a biographer, even though my first book [Zero: Biography of a dangerous idea] was nominally a biography of a number. But when Hawking died and I saw the outpouring of grief, I was surprised by how little of it was about his science. There was more to the human than the simple picture people had. I had encountered him a few times, and I was tapped into the social circle of cosmology, so I knew how he was assessed. I decided it was worth doing a real, probing biography that got to Hawking as a human, as opposed to Hawking as a symbol.

What did you know before you started researching the book?

It was a complex picture. Perhaps the clearest event where I was watching from the inside was his 2004 announcement in Dublin that he had solved the black hole information paradox [which suggests that Hawking radiation violates quantum mechanics because it erases information from the Universe]. In speaking to people who were there, almost no one was convinced. There was this poignancy I was picking up, that you had this man who was beloved — his students really loved him, and he’d made some major contributions — but then he got up in front of people and no one bought it. People were wondering why he did it.

But for the public at large, he had this status as an oracle, and it really didn’t matter what he was talking about.  Continue reading
