News from Adrian’s blog is that Sean Cubitt has a blog. Now, Sean’s writing is not for the faint at heart but for the strong of mind. Eg:

The multidimensional mysteries facing the analyst of light in the early 21st century are neither more nor less characteristic of our times than the explorations of Groseteste or the indications of Newton were to theirs. The answer, the first part of the answer, to the question “What is Light?” is “Light has a history”, not only as practice, nor even as an experience, but as an idea. Informing and informed by technologies and techniques, evidence and sensation, light changes. [Light 2]
