Do you try to pronounce physics terms as they sound in their language of origin?

By Hamish Johnston

Like many disciplines, physics incorporates words from a number of different languages – and this can often leave a physicist tongue-tied.

How should a native English speaker pronounce Einstein, for example? Should it be the Germanic “Ein-shtein” or the anglicized “Ein-stein”? How should one say De Broglie, Raman or Bernoulli? Should a native English speaker even attempt zitterbewegung, or translate it to “trembling motion”?

I’m sure that some physics terms of English origin are tricky for native speakers of other languages, and their pronunciations are sometimes adjusted accordingly.

Some believe that making an effort to use the original pronunciation shows respect and knowledge of the origin of a word. Others are happy to use the pronunciation they are most comfortable with.

Hawking’s academic boycott divides opinion

By James Dacey

Do you agree with the principle of academic boycotts?

Yes
No

Have your say by taking part in this week’s Facebook poll. As always, please feel free to explain your answer by posting a comment on Facebook or below this article.

This question has arisen after it was revealed yesterday that Stephen Hawking will be boycotting a prominent conference in Jerusalem in protest against the policies of the Israeli government. The British cosmologist and science communicator had been set to talk at the Israeli Presidential Conference: Facing Tomorrow, which will take place in June and which will feature a string of high-profile speakers, including Bill Clinton and Tony Blair. But the University of Cambridge has confirmed that Hawking, who is director of research at its Centre for Theoretical Cosmology, has pulled out of the conference for political reasons. Physics World has spoken to a university spokesperson who confirmed that Hawking has sent a letter to the conference organizers to explain his decision not to take part. The UK newspaper the Guardian has today published what it says is the full text of this letter, dated 3 May.

“I accepted the invitation to the Presidential Conference with the intention that this would not only allow me to express my opinion on the prospects for a peace settlement but also because it would allow me to lecture on the West Bank. However, I have received a number of e-mails from Palestinian academics. They are unanimous that I should respect the boycott. In view of this, I must withdraw from the conference. Had I attended, I would have stated my opinion that the policy of the present Israeli government is likely to lead to disaster.”

In the May issue of Physics World, science writer Jon Cartwright explores some of the most profound questions about the nature of reality. His feature, “The life of psi”, engages with an apparently simple question: what are quantum wavefunctions? Of course, like many of the most interesting questions in physics, the answer to the question is far from elementary. In fact, it is a question that goes right to the heart of quantum mechanics and philosophy, and one that has puzzled some of the greatest minds for the best part of a century.

My colleague, Hamish Johnston, has just returned from a trip to CERN, where he was granted access to the insides of the Large Hadron Colider (LHC), which is currently being upgraded. He has shared some great photos from his trip on the Physics World Facebook page, including some snaps of the interior of the detector experiments.

What is the best way to measure a researcher’s contribution to science?

By James Dacey

In an opinion article just published on this website, the historian and philosopher Robert Crease discusses the pitfalls when trying to measure the “value” of artefacts in culture and society. The article was inspired by an appearance Crease made at a group debate at the Museum of Modern Art (MoMA) in New York City. The panel were trying to identify ways to measure the museum’s impact on culture and the wider economy.

Crease refers to something known as Goodhart’s law, which he explains as follows.

“Named after the British economist Charles Goodhart, who devised it in 1975, the law essentially says that once a measure is chosen for making policy decisions, it begins to lose value as a measure. Goodhart applied it to banking policy, but in other fields, too, measurement can distort not only the practice being measured, but also perception of the goal.”

Should scientists speculate openly in the mainstream media about new science results?

By James Dacey

The first science results from the Alpha Magnetic Spectrometer (AMS) present a mixed bag for both scientists and journalists. On the one hand, they show that the machinery of this high-profile $1.5bn mission is actually working. And as my colleague Michael Banks reported earlier today, the excess of positrons, confirming previous measurements, represent an important step in the hunt for dark matter. But on the other hand, this was not a moment to break out the champagne at the celebration of new physics. In reality, it was an important step in testing the precision of the instrument, as well as a reminder that we all need to be patient while we wait for more data.

Given the scale and scope of the AMS mission, it is not surprising that the scientists involved in analysing these first results are keen to share their excitement with the general public. One way they have been doing this is by talking to the media and speculating about the significance of the findings. I find it really interesting to look at how the results have been covered in the headlines of the mainstream media. The BBC ran with “Alpha Magnetic Spectrometer zeroes in on dark matter”. Over the pond, the New York Times went for “Tantalizing New Clues Into the Mysteries of Dark Matter”, adopting the classic science-writing metaphor of a detective story. Both parties presented these early results as an exciting development in a gripping plot to uncover one of the long-standing mysteries of the cosmos.

What is the most common problem with academic presentations?

By James Dacey

Whether you love giving them or loathe the entire experience, everyone has to deliver a presentation at some point during an academic career – be they student or professional researcher. It might be the presentation of your results to supervisors and peers. Or it might be an outreach talk to explain your research to people who have probably never heard of you or your very interesting academic niche. There is no magic formula to giving a successful presentation, but instinctively I think we all know when it’s gone well. Likewise, I think we all know when we could have spent a bit more time whipping those slides into shape, or when we perhaps should have put a bit more thought into the appropriateness of that risqué joke.

Should more leading scientists engage in public service?

By James Dacey

Richard Feynman

Richard Feynman – undoubtedly one of the greatest scientists of the 20th century – died 25 years ago this year. To mark the passing of this physics and cultural icon, the BBC and the Open University have teamed up to produce two television programmes about Feynman’s life and work. The first programme aired in the UK on Monday, a docudrama called The Challenger portraying the role Feynman played in the investigation into the causes of the Challenger disaster. Readers in the UK can watch the programme here. Later this year, the BBC will broadcast a documentary about Feynman’s life.

I enjoyed Monday’s drama. I thought William Hurt did an excellent job of playing a smart and humane Richard Feynman, without over-cooking the “eccentric bongo-player” aspects of Feynman’s personality. Hurt certainly earned his wages, as the plot focused almost exclusively on how the Nobel laureate navigated his way through the alien world of high-level US politics, with all its game-playing and vested interests. My only criticism would be that because the film was so intensely focused on Feynman’s moves and responses, we didn’t really get to know any of the supporting characters.

Which astronomical objects do you find the most fascinating?

By Tushna Commissariat

This week marks 50 years since astronomer Maarten Schmidt’s discovery of the quasar, using the giant Palomar Observatory telescope. Quasars or quasi-stellar objects are a kind of active galactic nucleus that astronomers believe are powered by supermassive black holes and are scattered throughout the universe. They have always fascinated me, being some of the brightest, most distant and highly red-shifted astronomical objects in our universe. Over the years, thousands of quasars have been identified and they have dramatically influenced our ideas about the scale of the observable universe and have helped astronomers shed some light on the early universe.

In fact, just this week an international team of researchers announced the discovery of an extremely rare triple quasar system – only the second one observed to date. These systems are considered to be extremely rare and are difficult to spot. By combining multiple telescope observations and advanced modelling, the team – led by Emanuele Farina of the University of Insubria in Como, Italy – was able to discover the triplet quasar, called QQQ J1519+0627. The researchers say that light from the quasars has travelled nine billion light-years to reach us, meaning that it was emitted when the universe was only a third of its current age. Advanced analysis confirmed that what the team found was indeed three distinct sources of quasar energy and that the phenomenon is extremely rare.

So in light of these exciting findings, in this week’s Facebook poll we are asking you to pick your favourite astronomical objects.
