“The art of naming glitches” by Nutsinee Kijbunchoo/Antimatter Webcomics (click to enlarge).

Have you ever wondered how the LIGO collaboration managed to tease out the tiny signal from gravitational wave GW150914 from all the background noise in its kilometre-sized detectors? Well you’re in luck because experts from the LIGO detector characterization group have written a lively piece on the CQG+ blog called “How do we know LIGO detected gravitational waves?”.

It’s packed full of fun facts; for example, did you know that detecting GW150914 is roughly the same as measuring a change in distance the thickness of a human hair between Earth and Alpha Centauri, the closest star to Earth? But be warned, the article is also full of technical terms such as “whistles”, “blips”, “koi fish” and even “Fringey the sea monster”. These are illustrated in the above graphic by LIGO physicist and artist Nutsinee Kijbunchoo.

Metamaterials are always a hot topic at the APS March meetings, and this afternoon we were treated to an array of the latest developments in the field. Just in case you have not come across the term before, a metamaterial is an artificially crafted material that aims to achieve the naturally unattainable. These materials are engineered to have special physical properties – some metamaterials act as optical or acoustic cloaks, while some can harvest energy or be used to dissipate it in some form.

Paolo Celli of the University of Minnesota in the US loved playing with LEGO bricks as a child. Now, the physicist still gets to play with LEGO, as his team has been using the bricks both to understand how metamaterials interact with waves and also as an inexpensive and accessible outreach medium. While the researchers initially looked at 3D printing to develop their platform material, they soon found that LEGO bricks attached to a baseplate made for an agile, versatile, low-cost platform that was not highly damped and could be easily reconfigured.

Celli and colleagues have already used the LEGO to experimentally demonstrate phononic band gaps and the associated energy-trapping mechanisms. They are currently working on demonstrating the control of wavelengths that are larger than the width of waveguides realized in the brick pattern, with potential applications in subwavelength wave focusing and imaging. We will be talking to Celli tomorrow, so watch out for more on LEGO metamaterials soon.

Lilting to the LIGO tune, Fukushima five years on and more

 

By Tushna Commissariat

Looks as if LIGO’s gravitational-wave discovery is still rocking all over the world, as you can now groove to the dulcet tones of singer and physicist Tim Blais, who runs the acapellascience channel on YouTube. With some help from the Perimeter Institute in Canada, the singer has created his latest “nerd-pop” parody, titled “LIGO Feel That Space” (sung to the tune of The Weeknd’s “Can’t Feel My Face”). After you listen to the catchy tune above, take a look at this interview with Blais on the Perimeter website to find out just how he creates his songs and how he went from physicist to a viral YouTuber.

By Hamish Johnston

What to do with an abandoned mine? “Turn it into a neutrino and dark-matter detector” is probably what most physicists would say. But we have lots of those already, so how about “A cosmic landscape worthy of the ancients”? That’s how the artist Charles Jencks describes the Crawick Multiverse, which is located in a former open-cast coal mine in the Scottish countryside about 50 miles south of Glasgow. The “striking landscape of distinctive landforms” includes two mounds representing the Andromeda and Milky Way galaxies and a Comet Walk that uses standing stones to emulate a comet’s tail. If the photograh above is any indication, it looks like a lovely day out.

Female astronomers through the ages, science-inspired phone cases and the return of the incandescent light bulb

Portraits of 21 leading female astronomers

The first documented female astronomer in Britain was Margaret Flamsteed (1670–1739), who worked with her husband John at the Royal Observatory in Greenwich. That’s according to astronomer Mandy Bailey of the UK’s Royal Astronomical Society, who has written an article entitled “Women and the RAS: 100 years of Fellowship”. As the title suggests, this year is the centenary of the first women becoming fellows of the RAS.

To celebrate the centenary, the RAS commissioned Maria Platt-Evans to photograph 21 leading female fellows. The portraits appear above and are also presented in the slide show “Women of the Royal Astronomical Society”, which includes short biographies.

By Matin Durrani

Happy new year and welcome back to Physics World after the Christmas break.

It’s always great to get a new year off to good start, so why not tuck into the first issue of Physics World magazine of 2016, which is now out online and through the Physics World app.

Our cover feature this month lets you find out all about the Planck mission’s new map of the cosmic microwave background. Written by members of the Planck collaboration, the feature explains how it provides information on not just the intensity of the radiation, but also by how much – and in which direction – it’s polarized.

Tiny gifts for world leaders, Hubble’s birthday and more

3D Great Wall of China section

By Hamish Johnston and Tushna Commissariat

Last month, China’s president Xi Jinping’s was on a state visit in the UK and while here, he toured a few academic institutions, including the UK’s new National Graphene Institute (NGI) in Manchester and Imperial College London. As we reported in an earlier blog, Nobel-prize-winning Manchester physicist Kostya Novoselov presented President Xi “with a gift of traditional Chinese-style artwork, which Kostya himself had painted using graphene paint”. This week we found out that the Imperial scientists also presented him with a “tiny gift” in the form of a 50 µm scale version of a section of the Great Wall of China, imaged above, created with a Nanoscribe 3D printer. Prince Andrew, who was also on the visit, was given an image of a panda leaping over a bamboo cane, which was printed on the tip of a needle.

Comic book fusion, Nathan Myhrvold on innovation, and picking winners of the Global Physics Photowalk

By Hamish Johnston

The comic book artist Frank Espinosa and Princeton University’s Sajan Saini have joined forces to create a comic book called A Star For Us. The book begins with a brief history of our understanding of nuclear fusion in the Sun and goes on to chronicle the challenges of creating a mini-Sun here on Earth.

Espinosa and Saini – who is a physicist turned professor of writing – spent time with physicists at the Princeton Plasma Physics Laboratory. Espinosa says that he was impressed by the researchers enthusiasm for the future of fusion energy. “I was trying to channel that energy of hope,” he explains.

“The mood of the comic tries to really capture a sense of a vast cosmic scale being made palpable, being made into something that we can realize within our own hands,” says Saini. I agree and you can judge for yourself by downloading a PDF of the comic book free of charge.

The physicist and former chief technology officer at Microsoft, Nathan Myhrvold, has a nice essay in Scientific American about the roles of the private and public sectors in driving technological innovation. He explains that when Microsoft Research was created in 1991, the company was keen on not making the same mistakes as AT&T, IBM and Xerox – which were all in the process of winding down their world-famous research labs. The problem was that these firms funded research in areas that they were not immediately able to exploit commercially. Myhrvold points out that many of the technologies first developed in those labs – including the transistor and giant magnetoresistance data storage – made much more money for fast-moving competitors such as Microsoft than they did for the companies that did the basic research.

Using pictures to describe light

"Bullseye sky" by Michael Berry.

“Bullseye sky” by Michael Berry.

By Kate Gardner

“Pictures convey abstract concepts to each other and to ourselves,” explained Michael Berry last night in his talk “Optica Fantastica: Nature’s optics and our understanding of light” here at IOP Publishing in Bristol as part of the city’s Festival of Ideas. Berry, who is the Melville Wills emeritus professor of physics at the University of Bristol, began by declaring that he was going to take the “opposite approach to Einstein”. Whereas Einstein said, “I want to know God’s thoughts, the rest is just detail”, Berry is interested in those details.

Sponsored by the Institute of Physics, which publishes Physics World, the talk was held to celebrate the International Year of Light 2015 and in it Berry ran the audience through the four levels of understanding light: rays, waves, polarization and quantum. He showed beautiful pictures from his own research but also included some artworks related to the phenomena he was explaining and even quoted passages from novels.
