If the weekend of provocative public talks TEDxSydney accepted your application to be part of their 800-strong audience, then like me, you would have had the privilege of spending your Saturday sitting in a dark room listening to lecturers talk about their work.

Exhibit A.


However if you didn’t make the cut, or couldn’t afford the $160 entrance fee, you’d have been more than welcome to camp out in the hall with the rest of the plebs. The lectures and performances are broadcast free and speakers happily participate in lively Q&A sessions with their eager audience.

TEDxSydney, the local incarnation of the wildly successful TED events (TED standing for Technology, Entertainment and Design), was held at Carriageworks in Sydney over the weekend. Billed as “the ultimate brain spa”, participants were treated to performances from Tim Freedman and Katie Noonan, along with thought-provoking ideas from architects, philosophers and social entrepreneurs.

Of course the true genius of TED is that in between the lectures, the carefully curated audience members are herded into a giant room, plied with fantastic food and encouraged to “start a conversation with someone you don’t know”.

Here are the sparkiest ideas from this year’s event:

‘Flipping’ teachers the keys

Chris Anderson is venerated in the Cult of TED. The Oxford-trained philosopher and journalist used this year’s conference to introduce TED-Ed, a free online archive of animated videos that can be used by teachers to transmit key concepts.

Professional animators from around the world volunteer their time to help teachers translate their lessons into interactive videos which can then be viewed by students in their own time.

Multiple-choice questions check that students are learning and while faster students can use the site as a launch pad to explore a world of related topics, slower students can rewind as many times as they need to understand the lesson.

Best of all, the website allows teachers all over the world to change the title or questions in any TED-Ed video and re-publish it themselves. The videos can be customised to suit the class, and teachers can track their students’ progress through the video’s unique URL.

“Everything that TED has achieved thus far has happened by throwing the keys to other people,” Anderson says. TED-Ed is certainly an example of that.

Killing the ‘green vomit’

GetUp! co-founder Jeremy Heimans wants consumers to be more “irrational”.

Despite the fact that 75 per cent of people say they intend to switch to green products, consumers repeatedly choose price over environmental credentials, and only two per cent will actually put their money where their mouth is.

Meanwhile, the word “green” has become so mainstream that it no longer means anything. A quick Google of the word throws up an endless “green vomit” of vaguely leafy logos, and consumers have become increasingly wary of “green-washing”.

While we wait for technological advances and government regulation to level the playing field for green products, Heiman thinks that environmentally-friendly products need to tap into different, more irrational instincts to encourage consumers to buy green.

The dawn of quantum computing?

Quantum computers have long been seen as science fiction - fun to think about, but frankly, not particularly practical.

That could be about to change.

In February this year, Professor Michelle Simmons, physicist at UNSW and 2011 NSW Scientist of the year led a team of international scientists who successfully created a working single-atom transistor.

Computers that are able to crunch through reams of data at quantum speed would revolutionise everything from weather predictions to data encryption, and while Professor Simmons’ achievement is still just a proof-of-concept, her breakthrough could herald a new age of quantum computing.

Renovating and integrating with Asia

Tim Soutphommasane grew up in Cabramatta and still remembers the giant gateway with the inscription exhorting citizens “to be renovative and integate”.

The Oxford-educated philosopher reckons it’s advice that Australians would do well to consider.

New migrants are urged to assimilate, but multiculturalism is a two way street, and Soutphommasane says that Asia has plenty to teach Australians. 

Confucianism is a good counterpoint to Western notions of family, while Asia’s nascent struggles with democracy give us a chance to reflect on the health of our own political system.

As Australia strides into the Asian century, Soutphommasane argues that we need to rethink who’s doing the renovating, and who’s doing the integrating.

Taking play seriously

Psychologist Evan Kidd never had an imaginary friend but he wishes he did.

The senior lecturer at ANU has written over 40 scientific papers, but his research on imaginary friends is by far the most famous.

Some 65 percent of children have them at some point, and children with imaginary friends are more creative and have better language skills.

As US schools cancel recess to try to cram in more learning, Kidd reminds us of the value of letting kids be kids. “We need to start taking play a bit more seriously,” he says.

Which begs the question: “Where can I buy an imaginary friend?”

      The idea that teachers can use the internet as a teaching aid has only one problem.  In education the bureacracy wants to hold onto its little bit of power and get money from information.  Not many teachers try to set up a web page for their students, even when the content is to be their own intellectual property.

      ‘Which begs the question: “Where can I buy an imaginary friend?” ‘
      The answer is obvious - have a chat with Abbott ‘s mate.

      Actually TEDx events are held around Australia so this is hardly “the local incarnation”.

      Given the author is clearly a Sydneysider I can forgive her presumption that the only things that happen I Australia happen in Sydney. After all, she lives in the most polluted, crowded, trafific-jammed and economically retarted city in Ausralia. One must make allowances.

      An idea I put on TED :-
      How we get to Mars
      There are of course a many factors that make a mission to Mars a difficult undertaking.
      I will present the following problems that my idea addresses.
      1) Creating a big enough space craft to carry a crew plus food supplies and other equipment.
      2) Space craft size restrictions based on existing launch vehicle capacity.
      3) Building space craft components rugged enough to withstand launch trauma.
      I am of the belief that an existing technology can overcome at least these obstacles and allow greater flexibility to address the many other obstacles as they present themselves.
      3D Printing
      It could be said that current 3D printing is in its infancy, my belief is that the key is within the materials that a 3D printer can use like carbon, silicon, etc ,etc. Being able to actually print space craft in space with many of its electronic systems incorporated into the skin and structure of the craft as well as shielding etc.
      Satellite 3D Printing factories
      3D printers could first be tethered to the International Space Station. These printers are then fed raw materials ferried to the space station by existing rockets.
      The Benefits
      1) There is potentially no limit to the size of the spacecraft, if required the spacecraft could in theory be kilometers in size.
      2) Because many of the electronic systems are actually built into the structure there is far more crew space.
      3) Having systems built into the craft allows more room for built in redundancy by multiplying the same systems throughout the craft.
      4) Habitats could be constructed on Mars surface prior to landing by sending 3D printers to Mars in advance followed by raw material supplies.
      5) Potentially any existing rocket designed to carry a payload could be used for supplying the printers.
      6) Once en route to Mars and on the surface crews will be able to create things as required possibly even being able to recycle existing 3D parts that are no longer used.
      The possibilities are endless.
      Imagine the whole interiour of the spacecraft is actualy a huge touch screen display, its the instuments, its a back projected image of space (appears clear) its face to face communication and craft control from anywhere within the craft.
      Image a craft completly seamless, no joins or nuts and bolts or any other fasteners.
      Skins with multiple functions
      eg:- outer layer solar collectors, 2nd layer batteries, 3rd layer electronics, 4 layer LCD.
      This is a suggestion for 4 layers, the number of layers and configerations is endless but it can be task specific.

      If we put a solar powered computer and 3D printer in an air chamber on Mars, all we’d need to do is scan ourselves here on earth and send an email ?

    • year of the dragon says:

      “If we put a solar powered computer and 3D printer in an air chamber on Mars, all we’d need to do is scan ourselves here on earth and send an email ? “

      Only if you were one dimensional.

      So, in your case, yes.

    • acotrel says:

      10:13am | 28/05/12

      We were talking about 3D ! It would be really great if we could scan Abbott, and send him somewhere a long way from here.  I wonder if the Hubble telescope includes a 3D printer ?

    • sunny says:

      Radiation is a huge problem for human space travel - the crew would probably be mutants by the time they reached Mars. Maybe the craft could generate a magnetic field to shield from radiation, which would require extra power, requiring ultra powerful solar cells and/or ultra powerful batteries. The earth would benefit big time from the subsequent advances in solar cell output and power storage. I say go for it!

    • SAm says:

      11:37am | 28/05/12

      RE: The Mars ship, I believe the best bet to overcome launch difficulties would be to construct said large vehicle in orbit. This would of course me more expensive, however might be the best option gievn the size of such a vehicle. I am actually unsure just how large a vehicle would be (even for only 2 or 3 astronauts) or what amount of supplies would be needed. I am also sure the right technologies currently exist, but clever innovation and implementation will be required. I truly hope to see a manned mission to Mars, and eventual settlement happen in my lifetime. The Mars trilogy by Kim Stanley Robinson is my favorite book series of all time, the red planet will always have a special place in my heart smile

      I laughed at that, well I thought I was laughing at that, but no, it was another article on the competence of the Labor government and the unity it is currently has the unions.

    • Al says:

      12:49pm | 28/05/12

      Alcotrel - even if something was scanned and sent to a 3D printer the original would still exist, too bad for you.
      (This is also ignoring the functionality of 3D printers which have a limited range of materials that they can currently ‘print’, and most are not biologicaly capable, and certainly not to the extent required to produce a human, although an artifical likeness may be possible re: Cyborgs etc.)

    • sunny says:

      01:26pm | 28/05/12

      .. the crew of this Mars mission would have to be half Labor voters and half Lib/Nat voters, otherwise they would get too bored in transit. The Lib members of the crew could move to suspend standing orders 5000 times between here and Mars, just to pass the time.

    • Tubesteak says:

      I liked the one about renovating and integrating with Asia. This is important. As 3 billion people increase their standard of living over the coming century it really means we are on the cusp of a huge wave. We should do everything we can to catch it.

      Also, many Asian cultures value saving over spending and that is something Australians could do much better.

    • Sloan says:

      10:22am | 28/05/12

      Yes indeed. We need to copy Asia. I have always aspired to live in a Bangkok or Mumbai. Not for me to live in Vienna or Munich or any of the great cities of the western world….

      Asia is all about making money from the modern day slaves that toil in these rich man paradises. I have no wish to import their “culture” here or indeed into any civilised nation.

      Start paying your citizens properly, promote equality of all your citizens and actually develop a culture of some value and then maybe Asia can sit at the table with other civilised nations.

    • Tubesteak says:

      01:20pm | 28/05/12

      Well, I think we’ll just leave that there…...

    • stephen says:

      08:56pm | 28/05/12

      Asian nations have, especially China, a magnificent cultural heritage, and they have very much to teach us.
      But as always, a fine culture can cause strife if the associative Political systems do not allow for certain sections of a population to retain their own ‘ignorance’ ... in other words, these countries, almost without exception, have a dreadful Human Rights record, and I think that until this matter is settled internally and obviously to the satisfaction of observer countries, then I think that what we can learn from these Governments, is to stay away.
