Sergei Larenkov has photoshopped together modern images of St Petersburg with photos taken during the brutal Siege of Leningrad during WWII.

Sergei Larenkov’s images.

Very powerful and amazing images.

Broadband for Arnhem Land

From the ABC’s 7:30 report, a good news story about the Broadband Revolution coming to Arnhem Land in the Northern Territory. A fibre optic cable has be laid into Arnhem Land. This is great story in so many ways:

  • The technical hurdles that needed to be over come in laying cable in a harsh environment including under a crocodile infected river.
  • The positive social impact for education and health resulting from broadband.
  • How culturally  sensitively the whole project was managed, with traditional owners from the local Aboriginal communities being consulted and involved in the project.

ABC (au) Radio National launches Pool

via Boing Boing

ABC Radio National has launched Pool:

It’s a place to share your creative work with the Pool community and ABC producers – upload music, photos, videos, documentaries, interviews, animations and more. It’s a collaborative space where audiences become makers. – About Pool

One aspect of Pool that got my attention is the use of Creative Commons licences. It is great to see the ABC exposing Creative Commons, RSS feeds and the like to their audience. The, government funded, ABC and particular Radio National and Triple J, have often been early to embrace aspects of new media. Radio National were one of the first old media organisations to offer podcasts of their programs.

I, an Australian, discovered the Australian Broadcasting Corporation’s Pool via post on Boing Boing, a North American blog, by Cory Doctorow, who lives in the UK. The web is truely global medium.

Radiohead’s “House of Cards” video made without cameras

I am a big fan of Radiohead, their album In Rainbows and cool uses of technology, so this is the kind of think I like. The video for “House of Cards” from In Rainbows was not shot with cameras in the traditional sense. 3D data was captured using lasers and then rendered to produce the video. Very Cool.

Astronomy study proves mathematics theorem

From New Scientist, Astronomy study proves mathematics theorem. As an astronomy and maths geek and teacher, this is the kind of story that makes me smile. The research concerns gravitational lens. This phenomenon occurs when the light from a very distant object is bent by the gravitational field of some objects between the distant object and the observer. This was a prediction of Einstein’s general theory of relativity. Depending on the mass and shape of the objects who’s gravitational field results in the lensing effect, multiple image of the distant object can be observed, this is where the mathematics comes in. It turns out that for a lens made of n stars, 5n – 5 is the maximum number images. It is not every day that The fundamental theorem of algebra is mentioned in the media, even in New Scientist 🙂 This is an example of how Pure Mathematics that is developed without any direct practical application can be vital to work at some later time. Another example is the applications of number theory to cryptography.
