Semi-Final Program Grid for John Ashmead
This is the Semi-Final program schedule. John Ashmead may or may not actually be on these items, but probably will. However, due to circumstances beyond our control, modifications to the program can occur throughout the convention.
|Saturday 3:00 pm: Invisibility: Theory & Practice (Ends at: 3:55 pm)|
Panelists: John Ashmead (M)
How do we hide a jet fighter, a tank, even a city from sight? For millennia people have dreamt of invisibility rings, caps, & cloaks: how close are we to Harry Potter territory? Progress in the last ten years has been extraordinary, and, with some help from general relativity, 3d printers, advanced photonics, and more than a pinch of ingenuity, we can now bend, fold, & spindle light in ways unimagined ten years ago.
