Gizmodo has published a little piece about what we things would look like if we could see wi-fi signals. While it’s quite interesting, for example:
A ‘normal’ field of wi-fi is typically spherical and can extend 65 to 100 feet.
…(i.e. they’re 3d, not simply unidirectional), it’s also not ever so scientific, as if we were able to see wi-fi, we’d surely be able to see all sorts of other (currently invisible) electromagnetic waves as well: infra red, ultraviolet, radio waves etc etc. The picture would surely be far more complex. Your microwave oven would be psychedelic.
Above is a bit of Washington DC with a depiction of low level wi-fi hanging around the Washington Monument like a colourful mist (or smog, as the hypochondriacs would have you believe). And below, an image showing the decreasing amplitude of the wi-fi waves as they get further from their source. That’s why you can’t get a signal if you’re too far from your router.
My physics A-level made me wonder if the reflection from the pond would happen. And then I decided that it probably would, since wi-fi is represented as being within our visible spectrum.
But while this is all very pretty, does it really mean anything?
Well no, it doesn’t. But it is very pretty. But I was thinking that it was rather sad that we couldn’t see this sort of stuff with our naked eyes, instead of having to resort to arty depictions. And then I read this comment on the Gizmodo page:
I see things like this, all the time – I see them right now. They’re not as vivid as the photos, they’re more like transparent solids that act as waves and move in specific patterns. There’s more than one pattern though, which I assume would be other noise beyond the visual spectrum. They’re not eye floaties, I’ve researched every visual phenomena that I could find, and though one came close it didn’t really explain everything.
I want some of whatever he’s on.
