I am fascinated by the science of retrieving sound waves from wherever they go after they hit the air and dissipate. Since waves don’t end but keep spreading out, any sound ever made is technically still out there waiting to be rounded up and heard again. That’s incredible. It means, among other things, that if we could refine the science enough, we could literally hear epic moments like the Gettysburg Address or re-experience sweet, personal exchanges like a baby cooing. How eerie yet thrilling would it be to stand in a field in Pennsylvania and hear Abraham Lincoln’s actual voice brought back to life by modern technology corralling scattered sound waves? But, in some ways, I don’t think we need to wait for those advances. Have you ever been somewhere and heard the echoes of the past? Not specific words, maybe, but whispers of sound that seem to linger. In Chattanooga, Tennessee, there is a massive natural stronghold of 
great tactical benefit during the Civil War. The army that controlled Lookout Mountain, with its towering height and expansive view, was in a position of virtually impenetrable superiority, and as such it was the scene of fierce fighting. At the base of the mountain, if you stand very still and listen very carefully, the wind still carries the sounds of long ago. It is haunted. In Walt Disney Production’s The Haunted House, Mickey and friends are hearing things. I wonder if it would help to know it’s just trapped sound waves.
P.S. Enjoy your book, Little Rhys!
