Spotlight on the International Year of Light (IYL 2015)

By James Dacey

As science-inspired global initiatives go, it’s fair to say that the International Year of Light and Light-based Technologies (IYL 2015) burned brighter than its organizers could have imagined. IYL 2015 set out to raise awareness of the crucial roles light can play in areas such as sustainable development, education and health, and it did so through festivals, workshops, publications and a plethora of other activities. A final report published this week details some of IYL 2015’s key achievements and describes some of the year’s most memorable activities.

Among the highlights identified in the report is the Physics World film series “Light in our Lives”, a set of short documentaries about the role of light in people’s everyday lives. We commissioned the films as an official IYL 2015 media partner, embracing the collaborative and international dimensions of the year by working with filmmakers across the world. They include a film about how LED lanterns are enabling students to study after sunset in a rural community in India, and another about how lighting technologies are bringing a modern twist to Day of the Dead celebrations in Mexico City (see above).

A bright light in Mexico City’s historic centre

Museo de la LuzBy James Dacey in Mexico City

When you visit an unfamiliar city, you can often discover some hidden gems by just wandering the streets with your eyes wide open. This is what happened to Physics World editor Matin Durrani and me yesterday here in Mexico City when we stumbled across the Museo de la Luz (Museum of Light) in the backstreets of the historic city centre.

Located in an old Jesuit college with a beautiful courtyard, the exhibits are spread over three floors covering a wide spectrum of themes, from human vision to the history of the theories of light. What I loved about the place is that it really did offer something for everyone. Too often I find that museums can be great for kids or great for the type of serious adult who loves to leaf through tea-stained archives. El Museo de la Luz manages to hit a sweet spot, being informative and interactive but not too whizz-bang – that is certainly not what I needed yesterday with this jetlag!

A telescope for the Year of Light

The Galileoscope

The Galileoscope – yours for only $25.

By Michael Banks

Avid readers of may remember the Galileoscope – a low-cost educational telescope kit that was released for the International Year of Astronomy in 2009.

The telescope marked the 400th anniversary of Galileo’s first telescope, which he presented to policy-makers from the Venetian Republic on 25 August 1609.

Bright lights, big city: a lighting revolution comes to New York

“One well-lit place” is the best way to describe the exhibition hall at Javits Center in New York when it opened on Tuesday morning. I fully expected to be bedazzled at every turn because the venue is hosting LIGHTFAIR, the world’s largest lighting technology trade fair, and so the hall is packed with more than 600 booths designed to highlight, so to speak, the world’s lighting revolution.

Light lunch with a Nobel prize winner

By Robert P Crease in New York

I seldom go to the Javits Center, New York City’s big, ugly convention space where the food, drinks and parking are way overpriced. Its shows on fashion, furniture and food don’t interest me and it’s a 20-minute walk from the nearest subway station. I once heard comedian Seth Meyer quip that it’s “smack-dab in the middle of New York’s stabbing district”.

On Sunday I went for the first time in years to attend the inaugural lunch of LIGHTFAIR, the world’s largest lighting trade show that draws architects, engineers and designers from all over the world. The featured speaker was Shuji Nakamura, the Japanese-born American materials scientist who shared last year’s Nobel in physics for developing the blue LED. Nakamura described his research path – when he started virtually everyone was working on selenium and he said he chose gallium only because he thought it would make it easier to publish – and was joined on stage by Scott Rosenfeld of the Smithsonian American Art Museum.

New York dims its lights for birds

By James Dacey

It’s been a great week for birds – or at least those flying over the state of New York – after state governor Andrew Cuomo pledged to create safer migration routes for our feathered friends. All state buildings will now have to comply with a national US initiative that seeks to curb levels of light pollution, which can disorient birds and lead to huge numbers of avian deaths by “fatal light attraction”.

Many species of bird rely on the light from star constellations to help them navigate during spring and autumn migrations. Unfortunately, artificial light sources can throw the animals off course, and light reflected from glass can cause the birds to smack into windows, walls, floodlights and other hard surfaces. It is estimated that as many as a billion birds succumb to this cruel end each year in the US alone, according to the US Department of Agriculture.

IYL 2015 gets Swiss design makeover

Posters inspired by IYL 2015

IYL 2015 is the theme of this student poster project.

By James Dacey

One of the big aims of the International Year of Light (IYL 2015) is to take scientific ideas out of the lab to show the world just how inspiring and useful they can be. In the process, it can forge relationships between different communities, including scientists, engineers, artists, journalists, architects, politicians, aid workers…the list goes on.

Here in Bristol, where Physics World is produced, we’ve seen a fantastic local example of this by way of an art project at the University of the West of England (UWE). Second-year graphic-design students were set the brief of creating posters themed on IYL 2015. Last night we hosted an evening at IOP Publishing headquarters to showcase the students’ work and to let them find out more about science publishing.
