Touch from a Distance

Touch from a Distance

There's a likely apocryphal story about Guglielmo Marconi that I've never wanted to ruin with research.

I'm still going to tell it to you.

As the legend goes, the father of radio was struck with an epiphany while watching grains of pollen dance inside a puddle outside. People walking along the path would, unsurprisingly, stir the grains of pollen into motion with the vibrations from their feet. Marconi realized that, as all sounds are physical vibrations, and all vibrations have to propagate through something physical, all sounds in the history of the universe have been, in some way, “recorded” into our material world. Every piece of audio has a visual counterpart. We just don't tend to know where to look to find them.
