Codes, cyphers, and the National Cryptologic Museum

Outside the National Cryptologic Museum gift store is this replica of the Rosetta Stone. Created around 196 BC, it displays a decree from an Egyptian king, written in Egyptian hieroglyphs, Demotic script and ancient Greek.

Located at the edge of Fort Meade, Maryland, in an old, nondescript motel, is the National Cryptologic Museum. Admission is free, and with that admission you can explore how the worlds of communications, mathematics, and security intersect in cryptology.

Gettysburg National Battlefield Park

Parrott Rifle, a type of muzzle-loading, rifled cannon on a Napoleonic carriage, near the Peace Light in the northwestern part of the battlefield.

Gettysburg, Pennsylvania, is a lovely small town surrounded by farms. The area is awash in green, rolling hills, and is almost stereotypically serene and peaceful. This was not the case during July 1-3, when two massive armies collided in and Continue reading Gettysburg National Battlefield Park

Early version of Google

This was the early version of Google. Using these humble wooden drawers, generations of scholars and researchers, desperate students and cunning spies, despairing parents and fanatical bibliophiles, and every other shape and size of reader delved into the depth and breadth Continue reading Early version of Google

Along the Louisville waterfront

Louisville is a seaport, of sorts. The Louisville, Kentucky, “seacoast” is the waterfront along the Ohio River, with that other coastal state, Indiana, just across the water. Barge traffic has moved up and down the river for a couple of Continue reading Along the Louisville waterfront
