Wits U accelerates light – and maybe the Internet

Published

on

Wits University researchers have developed a way to accelerate light that could eventually lead to much faster internet speeds and benefits for medical technology, writes DUNCAN ALFREDS.

Professor Andrew Forbes and his team of the School of Physics have demonstrated that the technology could be used to create a 30 times increase in the bandwidth of communications systems.

The next generation of high speed internet will consist of fibre optical connections, which rely on the transmission of data by light. However, Forbes cautioned against immediate expectations from the world first development.

“Okay, at the moment this research is not directly coupled to this. In the present work I have shown how to make light accelerate, which is not something it is meant to do,” Forbes told Fin24.

Previously, Forbes and his collaborators have shown that light could be made to spin. In this latest work, they have created digital holograms.

Medical test technologies

“I create holograms that are written to LCD displays – like the TV in your house – and then teach the device to create the patterns of light I want,” said Forbes.

He joined the Wits School of Physics in March this year, and heads up the new Structured Light Laboratory that focuses on creating custom light fields using digital holograms. The research group creates complex light that exhibits interesting physical properties, which

they exploit for a range of applications.

“From a purely science perspective it is interesting to test old concepts with this new idea. For example, if we replace the ‘light’ with ‘electrons’, can we make self-accelerating electrons that do not radiate any light? This would be considered impossible before,” Forbes said.

But he also foresees using the innovation to develop medical test technologies that could speed up the diagnosis for certain conditions.

“On a more practical level, there is a drive toward lab-on-a-chip technologies in the biological and health sections. The idea is to make a diagnostic that is very small – electronic chip size – so that the samples are analysed in real time rather than transported to a large, physical laboratory.”

The accelerating light could be used to pump fluid so that accurate readings could be taken.

The research paper is available on the Wits website.

As selfie cameras rise, so must selfie etiquette

Selfies were once a sign of narcissism or self-obsession. Now they are the new normal, writes ARTHUR GOLDSTUCK.

You can blame Oxford Dictionaries for making the “selfie” respectable. After all, being named Word of the Year, as it was in 2013, does tend to soften some of the self-consciousness in this most self-conscious of actions.

Once seen as a symbol of narcissism and self-obsession, it is now the new normal, to the extent that most smartphones are sold on the basis of the front camera. Or, as that feature is now almost universally named by manufacturers, the “selfie camera”.

I was one of the hold-outs, having a near-allergy to the selfie. I still resist, but succumb more often than I would like. The reason for continued resistance is that it remains a big leap from the word becoming respectable to the action itself shedding its narcissistic image. 

For most, it’s already happened, and for that you can blame Ellen DeGeneres. She  choreographed the most famous group selfie yet at the 2014 Oscars, when she roped a bunch of actors into a group selfie, using the then-new Samsung Galaxy S5 smartphone. Her tweet of the photo became what was then the most retweeted posting ever on Twitter, and was estimated to have been worth a million dollars in marketing value to Samsung.

Ironically, it was Samsung’s up-and-coming challenger, Huawei, that came up with a new word for this type of selfie: the “groufie”. Thanks to an 8 Megapixel front camera on the new Huawei Ascend P7 camera that year which took the highest quality selfies – and groufies – possible on a smartphone at the time.

It didn’t end there, and selfies and groufies have morphed into variations like selfscapes (selfie in a landscape), skyfies (selfies from the air, using remote controlled devices) and jerkies (selfies to make an idiot out of yourself). I invented all of those on the fly, so it’s easy to imagine a new word emerging for every type of selfie.

Mickey’s 90th for SA

Disney Africa announced the local launch of the Mickey the True Original campaign, joining the global festivities honouring 9 decades of Mickey Mouse, his heritage, personality and status as a pop-culture icon.

Published

on

As 18 November 2018 marks 90 years since his first appearance in Steamboat Willie in November 1928, a series of world-wide celebrations will be taking place this year and South Africa is no different.

The campaign will come to life with engaging content and events that embrace Mickey’s impact on the past, present and future. The local festivities kick off in earnest this month, leading up to Mickey’s 90th anniversary on 18 November 2018 and beyond:

  • An exclusive local design project where ten highly talented South African artists will apply their own inspiration and artistic interpretation on 6-foot Mickey Mouse statues.
  • Once revealed to the public, the statues will form part of the Mickey the True Original South African Exhibition, inspired by Mickey’s status as a ‘true original’ and his global impact on popular culture. The exhibition will travel to 3 cities and delight fans and families alike as they journey with Mickey over the years. Featuring 4 sections highlighting Mickey’s innovation, his evolution, influence on fashion and also pop culture, the exhibition is in collaboration with Samsung and Edgars, and will visit:

o   Sandton City, Centre Court: 28 September – 14 October

o   Gateway Theatre of Shopping, Expo Explore Court: 19 October – 11 November

o   Canal Walk Shopping Centre. Centre Court: 16 November – 26 November

  • Samsung continues their collaboration with Disney as they honour Mickey’s 90th anniversary nationally at all Samsung and Edgars Stores. Entitled Unlocking the Imagination, fans are encouraged to visit these stores, take a selfie with a giant Mickey plush toy using their Samsung Galaxy Note9 and stand a chance to win not only a giant Mickey plush, but also an international family trip. Visit www.Samsung.com for more information
  • Mickey’s 90th Spectacular, a two-hour prime-time special, will be screened on M-Net 101 later this year. The elegant affair will feature star-studded musical performances, moving tributes and never-before-seen short films. Superstars from music, film and television will join the birthday fun for the internationally beloved character.
  • In addition, look out for special programming on Mickey’s birthday (18 November) across Disney Channel (DStv, Channel 303), Disney XD (DStv, Channel 304) and Disney Junior (DStv, Channel 309).
  • In retailers, Edgars will be stocking a complete collection of trendy fashion, accessories and footwear for the whole family, inspired entirely by Mickey Mouse.
  • Mickey will be the central theme of an in-store campaign nationwide this November and December, with brand new products, apparel, toys, as well as titles from Disney Publishing Worldwide, including books, arts & crafts and comics
  • Discovery Vitality and Disney are celebrating healthy, happy families this festive season by offering helpful and exciting tips and tricks on how to eat nutritious, yet delicious, foods, all inspired by Mickey. There’s also a trip to Disneyland Paris up for grabs. Log on to www.discovery.co.za/vitality for information.
  • And much more – check the press for updates

“Binding generations together more than any other animated character, Mickey Mouse is the “True Original” who reminds people of all ages of the benefits of laughter, optimism and hope,” says Christine Service, Senior Vice President and Country Manager of The Walt Disney Company Africa. “With his universal appeal and ability to emotionally connect with generations all over the world, no other character quite occupies a similar space in the hearts and minds of a global fan base and we are thrilled to be sharing these local festivities.”

Mickey’s birthday is celebrated in honour of the release of his first theatrical film, Steamboat Willie, on 18th November 1928, at the Colony Theatre in New York City. Since then, he has starred in more than 100 cartoons and can currently be seen on Disney Channel (DStv, Channel 303) in the Mickey Mouse cartoon series and on Disney Junior (DStv, Channel 309) in Mickey and the Roadster Racers.

South African fans are encouraged to share their Mickey Mouse moments on social media using the hashtag#Mickey90Africa.
