Be careful about giving legal advice. These are not legal where I live. Making explosives in any quantity is legal at a federal level in all 50 states without any kind of license but those darn states and cities make laws to restrict that. Mixing tannerite turns it into a federally, state, and

Timenutters-- The question was asked-- Why can't a large aperture high-resolution optic be used to locate bullet holes in a target at 800 yards? Consider this--: I often shoot at targets on the 600 yard berm at the Manatee Range (near Bradenton, FL). Typically, by 11AM the

How about a rubber-mirror, adaptive optics? We use this on our large telescopes to overcome the atmospheric scintillation, otherwise known as speckle-patterns. Works exceedingly well... Atmospheric turbulence can be described by a Kolmogorov distribution, or equivalently as a chaotic

Hi Roughly speaking, you know the distance to 0.1%. If the electronics are good to 0.01% they aren't going to contribute a significant amount of error. A fairly modest bare crystal will do quite nicely for the time base. No need to go any further. If you want to go time-nutty, put in a cell
