This summer many of you will watch smoke billowing out of buildings as yet another villain wreaks havoc on the New York skyline in the latest Hollywood blockbuster. I’m willing to bet that as you eat your popcorn you won’t be thinking about the Navier–Stokes equations of fluid dynamics. (Well, perhaps you will now that I’ve mentioned it!)
In fact, part of the reason that virtual smoke in films looks so realistic is because visual effects (VFX) specialists have applied the Navier–Stokes equations to their graphics. This was one of the interesting tidbits I learned from a talk yesterday in London by Rob Pieké, head of software at Moving Picture Company (MPC).
Pieké was speaking as part of a half-day event on “physics and film” organized by the Institute of Physics, which publishes Physics World. The gist of his presentation was that basic physics principles are used in a variety of ways to create special effects that capture viewers’ attention. “The audience wants to see something fantastical but grounded in reality,” said Pieké. Another example he gave was how naturally bouncing hair in computer-generated characters is modelled on mass—spring systems. Each individual hair could be modelled on as many as 30 masses connecting by springs.

You may remember that the “classical crossover” soprano star Sarah Brightman had been undergoing strenuous training at Moscow’s Star City complex before hitching a ride on a Soyuz rocket to the International Space Station (ISS) in September. The singer was set to pay a whopping £30m for a ticket that would have seen her embark on a 10-day journey into space. Brightman even recorded a special song in March that she was planned to perform on the ISS itself – you can watch the 5 News report above. But Brightman has now postponed the trip, putting out a brief statement on her website citing “personal family reasons” for the decision. One beneficiary of Brightman’s no-show will be the Japanese entrepreneur Satoshi Takamatsu, who had been training as Brightman’s back-up. Whether he’ll do his own version of her planned performance isn’t clear.

In a sweeping win for science-themed films at this year’s Oscars, British actor Eddie Redmayne has won the best actor award for his portrayal of the theoretical physicist Stephen Hawking in the film The Theory of Everything. Redmayne, 33, plays Hawking in the biographical film that was inspired by the memoir Travelling to Infinity: My Life with Stephen written by Hawking’s former wife Jane, who is portrayed in the film by the British actress Felicity Jones. The Theory of Everything was also nominated for best picture, original score and adapted screenplay, while Jones was nominated in the best actress category. Redmayne’s success at the Oscars comes after his win in the best actor category at this year’s Bafta awards, which also saw The Theory of Everything pick up best film. The movie chronicles Jane’s relationship with Hawking – from the early days of their courtship to Hawking’s diagnosis of amyotrophic lateral sclerosis at the age of 21 and his success in physics until the two divorced in 1995. I was lucky enough to attend an early screening of the film, and I thought it was a very worthy candidate for the awards season. You can read my review of the film here.

In recent years, science and science fiction have come together in cinema to produce a host of rather spectacular visual treats, the best of the lot being Christopher Nolan’s epic Oscar-nominated film Interstellar. That actual science has played a major role in film is pretty well known, thanks to the involvement of theoretical physicist Kip Thorne, who was an executive producer for the project. But in a near-cinematic plot twist, it has emerged that Thorne’s work on trying to develop the most accurate and realistic view of a supermassive black hole “Gargantua” has provided unprecedented insights into the immense gravitational-lensing effects that would emerge if we were to view such a stellar behemoth.

The results of a successful scientific experiment can make scientists very happy. Indeed, in the clip above, taken from the BBC TV series Human Universe, one scientist exclaims “holy mackarel!” when he sees the outcome he was hoping for. In the video, everybody’s favourite physicist Brian Cox carries out an experiment similar to Galileo’s Leaning Tower of Pisa experiment, where he tested that no matter the mass of objects, they fall at the same rate under gravity. In the video above, Cox drops a bunch of feathers and a bowling ball in the world’s biggest vacuum chamber – the Space Simulation Vacuum Chamber at NASA’s Space Power Facility in Ohio, US. In the slow-motion video, you can see with exquisite clarity just how accurate Galileo’s prediction was, as the feathers and ball land at precisely the same time. We came across this video on the Dot Physics blog on the Wired Science network, written by physicist Rhett Allain, where he has worked out some of the maths and pointed out some of the nuances of the above experiment, so make sure you take a look.

We’re always up for trying new formats and approaches to journalism here at Physics World. You’ve probably seen our documentary-type films, podcasts and 100 Second Science video series, but the latest addition to our repertoire is a short monthly video in which one of our editorial team highlights something in the upcoming or current issue as a kind of taster.
So this month, I decided to take the plunge and get in front of the camera myself to present the third edition of what we have started jokingly referring to in the office as our “fireside chats”. (Here are the July and August versions.)

This blog is a shameless plug for the latest Physics World podcast, in which I talk to Sean Carroll – the California Institute of Technology cosmologist who also serves as a science adviser to Hollywood.
I chatted with Carroll when he was in the UK speaking at the recent Cheltenham Science Festival and, in the podcast, you can find out about his favourite science-fiction films and why he thinks it’s important to get the science in such films right. Carroll also reveals who he thinks he’s most like in TV’s The Big Bang Theory.

This week, professional astronomers and enthusiasts all over the world pointed their telescopes (and satellites) at the comet ISON as it raced towards the Sun and had its closest encounter with our star yesterday. Of course, the big question was whether the “Sungrazing comet” would survive its close call. Now, it seems that no-one is quite sure – early on, it looked as if the comet faded rather dramatically, suggesting that its nucleus disintegrated, and then it disappeared completely as it made its way through the solar atmosphere, making scientists mourn its fiery death. But lo, today a very faint smudge of dust was seen again, and seems to be brightening up once more. For now, researchers are referring to ISON as “Schrödinger’s Comet” and we may have to wait a while to know for sure. Right now, it seems that some of the comet has survived, but just how much of it made it through and if it will be visible in the sky in December is unknown. In case you missed all the action yesterday, take a look at Phil Plait’s Bad Astronomy blog, where he was posting live updates on the comet and Karl Battams’s blog on NASA’s Comet ISON Observing Campaign site, where he explains what happens next.

The best thing about science fiction is that it is fiction, and nit-picking about scientific accuracy shouldn’t get in the way of telling a good story. That’s the theme of Roger Highfield’s review of the latest blockbuster Gravity. Writing in his old paper The Daily Telegraph, Highfield – who now works at London’s Science Museum – takes exception to a series of Tweets by the celebrity astrophysicist Neil deGrasse Tyson about the film. Among other things, the Tweets complain that Sandra Bullock’s hair should be wafting around in zero gravity, not hanging down as it would on Earth. Despite these and other “scientific holes big enough to fly a Saturn V rocket through” both Highfield and Tyson agree that Gravity is a film well worth seeing. The review is called “Gravity: how real is the science?“.

The story of Paul Frampton is so incredible that it’s hard to believe it really happened. How could anyone have been so foolish and left his family, colleagues and students in the lurch?
In case you don’t remember, Frampton is the 69-year-old British-born US-based theoretical physicist who in early 2012 travelled to Bolivia expecting to meet a 32-year-old woman he’d struck up a correspondence with on the Internet, who claimed to be the Czech-born lingerie model Denise Milani.
But when he arrived in Bolivia, Milani was nowhere to be seen and Frampton was instead met by a man who asked him to take what was supposedly Milani’s suitcase to Buenos Aires, where she would then meet him.
When Milani didn’t show up at Buenos Aires Airport either – and there has been no suggestion that she knew that her identity was being used – Frampton tried to board a plane back to the US but was arrested after airport-security officials discovered 2 kg of cocaine in his checked luggage. Although he insisted the drugs were not his, Frampton was sentenced in November 2012 to 56 months in jail, despite a campaign by physicists to clear his name.
