1. Adactio: Articles—Of Time And The Network

   A presentation about history, networks, and digital preservation, from the Webstock conference held in Wellington, New Zealand in February 2012.

   Our perception and measurement of time has changed as our civilisation has evolved. That change has been driven by networks, from trade routes to the internet. Now that we have the real-time web allowing instantaneous global communication, there’s a danger that we may neglect our legacy for the future. While the web has democratised publishing, allowing anyone to share ideas with a global audience, it doesn’t appear to be the best medium for preserving our cultural resources: websites and documents disappear down the digital memory hole every day. But we can change that. This presentation will offer an alternative history of technology and a fresh perspective on the future that is ours to save.

2. The Physics of Time

   When writing the Principia Mathematica, Isaac Newton declared his hand on most of the big questions in physics. He outlined the nature of space, explained the motions of the planets and conceived the operation of gravity. He also laid down the law on time declaring:

   “Absolute, true, and mathematical time, of itself and from its own nature, flows equably without relation to anything external.”

   For Newton time was absolute and set apart from the universe, but with the theories of Albert Einstein time became more complicated; it could be squeezed and distorted and was different in different places.

   Time is integral to our experience of things but we find it very difficult to think about. It may not even exist and yet seems written into the existence of absolutely everything.
