The Daguerreotype

The daguerreotype, an early form of photography, was invented by Louis Daguerre in the early 19th c. He collaborated with J. Nicéphore Niepce, who created the first permanent photograph, but completed the design alone following his partner’s sudden death.

A daguerreotype, produced on a silver-plated copper sheet, produces a mirror image photograph of the exposed scene. Daguerre’s process made portrait photography possible for the first time. How did the French government describe the invention?

The Didgeridoo

The didgeridoo, developed by the Australian Aborigines, is perhaps the world’s oldest wind instrument. Though the exact age of the didgeridoo is unknown, studies of rock art in northern Australia suggest that the Aboriginal people have been using it for approximately 1,500 years.

Didgeridoos measure about 4 ft (1.5 m) in length and are made from branches that have been hollowed out by termites. A 2005 study found that practicing the didgeridoo can help reduce what sleep-related conditions?

Dry Quicksand

Considered a mythic substance until recently, dry quicksand is loose sand that behaves like ordinary quicksand but contains no water and operates in a different manner. Though accounts of whole caravans being swallowed up by the substance have been discounted as folklore, researchers have demonstrated that aerating fine sand reduces its bulk density and creates a dry quicksand that could envelop an entire vehicle. How did fear of dry quicksand affect the planning of the Apollo moon missions?

Gerardus Mercator (1512)

Mercator was a Flemish geographer, mathematician, and cartographer who perfected the first map using the Mercator projection, the translation of the spherical earth to a two-dimensional flat plane. In it, parallels and meridians are rendered as straight lines spaced to produce an accurate ratio of latitude to longitude at any point. It permits mariners to steer a course over long distances without continually adjusting compass readings. What map-related term was coined by Mercator?

the Pine Burr Quilt

In observation of Black History Month, we (STATE SYMBOLS USA) are featuring the Pine Burr Quilt, the official state quilt of Alabama. The Alabama legislature designated the quilt an official symbol in honor of the Black women of the Freedom Quilting Bee. In 1966, Black workers were losing their jobs in retaliation for registering to vote, so the women formed a cooperative to sell their quilts, raising money for the Civil Rights movement and to help support their families. The quilts became famous, were sold all over the country, and have been displayed at the Smithsonian.
