Another fascinating article, this time about light and the absence of it, and the potential for that absence.

I often wonder about the absence of energy. What if black holes aren't hot? What if black holes dissipate heat and are cold and absent of energy? What if absolute zero doesn't exist because as with heat or time or space you can always add a bit on, the same as infinity plus one is still infinity. 

I saw this article yesterday and was immediately struck by the fact that these guys have effectively created a definite absence at the periphery, where previously there was blur of bleed over. Straight away you can see how this can totally refine imagery (no pun intended), but beyond that, it opens the door on `what isn't', and where `what isn't' is ... there might be something paradoxical there ... that or I'm talking shit.

An fascinating article about memory in older people.

A fascinating article. I wonder (and I'm sure I read something about this in another article) whether being open and welcoming to change, accepting, and enjoying change has something to do with the process? 

I see it a lot, people who are stuck in the era they were born, no change is good change, the rose-tinted hindsight glasses go on and they effectively insulate themselves from new external stimuli.

I know we can all be guilty of it, and music is one of the indicators, and it's catered to widely (70s, 80s, 90s stations etc) and thus feeds itself. The whole notion that the visual cortex plays into memory, suggests an emotional `excitement' something new, a challenge first perceived visually. Sound, music has the same attributes but in a different way. It would be interesting to see if further studies find a connection to `new stimuli' regardless of source.
