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

3D Great Wall of China section

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.

Converging streams, secret science and more


By Tushna Commissariat

Regular readers will know that Physics World‘s Hamish Johnston and Louise Mayor will be attending the “Convergence” conference at the Perimeter Institute in Canada from tomorrow onwards.  While the conference will undoubtedly prove exciting – just look at this list of speakers – it looks like the institute already has convergence on its mind as this month’s Slice of PI contemplates the “converging streams” of art and science. The video above features Perimeter researcher and artist Alioscia Hamma, who finds solace and symmetry in both his art and physics. Watch the video and read more about his work on the Perimeter blog.

3D printing, Ada Lovelace and controversial bloggers

By James Dacey

One of the more inspiring stories we have come across this week was the tale of a resourceful inventor in the West African nation of Togo. Kodjo Afate Gnikou has managed to build a 3D printer at the meagre cost of $100 by mainly using parts he found in a scrap yard in the capital city Lomé. The story is described on, which says the machine has been constructed from broken scanners, computers, printers and other e-waste.

On the subject of 3D printing, Wired magazine ran a story about how the UK supermarket chain Asda is planning to trial a 3D printing service at its store in York. They will be offering customers the chance to take a break from their shopping to have a full body scan, which will be used to create miniature dolls of themselves. Prices apparently start at £40 and Asda boasts about how lifelike these dolls can be: “The technology produces highly realistic ‘mini me’ figurines at whatever scale you like!”

Portrait of Ada Lovelace

From a shop in York to the next story that involved celebrations all round the world. Tuesday was Ada Lovelace Day 2013. The annual celebrations, which are now in their fifth year, are held to recognize the achievements of women in science, technology, engineering and maths (STEM). The annual event was founded in 2009 by the social technologist and writer Suw Charman-Anderson “as a response to online discussions about the lack of women on stage at tech conferences”.

This year events included a mass Wikipedia “editathon” at the University of Oxford in an attempt to raise the profile of women’s contributions to science, as described in this article in the Guardian.
