Inspiration
Spirit duplicator
A spirit duplicator (also referred to as a Ditto machine in North America, Banda machine in the UK or Roneo in France and Australia) was a printing method invented in 1923 by Wilhelm Ritzerfeld and commonly used for much of the rest of the 20th century. The term "spirit duplicator" refers to the alcohols which were a major component of the solvents used as "inks" in these machines. The device coexisted alongside the mimeograph.
Stratigraphy
Stratigraphy is a branch of geology which studies rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. Stratigraphy includes two related subfields: lithologic stratigraphy or lithostratigraphy, and biologic stratigraphy or biostratigraphy.
Wardian case
The Wardian case was an early type of sealed protective container for plants, an early version of the terrarium. It found great use in the 19th century in protecting foreign plants imported to Europe from overseas, the great majority of which had previously died from exposure during long sea journeys, frustrating the many scientific and amateur botanists of the time. The Wardian case was the direct forerunner of the modern terrarium (and the inspiration for the glass aquarium), and was invented by Dr. Nathaniel Bagshaw Ward (1791–1868), of London, in about 1829 after an accidental discovery inspired him.
Winogradsky column
The Winogradsky column is a simple device for culturing a large diversity of microorganisms. Invented in the 1880s by Sergei Winogradsky, the device is a column of pond mud and water mixed with a carbon source such as newspaper (containing cellulose), blackened marshmallows or egg-shells (containing calcium carbonate), and a sulfur source such as gypsum (calcium sulfate) or egg yolk. Incubating the column in sunlight for months results in an aerobic/anaerobic gradient as well as a sulfide gradient. These two gradients promote the growth of different microorganisms such as Clostridium, Desulfovibrio, Chlorobium, Chromatium, Rhodomicrobium, and Beggiatoa, as well as many other species of bacteria, cyanobacteria, and algae.
Wyld’s Great Globe
Wyld's Great Globe (also known as Wyld's Globe or Wyld's Monster Globe) was an attraction situated in London's Leicester Square between 1851 and 1862, constructed by James Wyld (1812–1887), a distinguished mapmaker and former Member of Parliament for Bodmin. At the centre of a purpose-built hall was a giant globe, 60 feet 4 inches (18.39 m) in diameter. The globe was hollow and contained a staircase and elevated platforms which members of the public could climb in order to view the surface of the earth on its interior surface, which was modelled in plaster of Paris, complete with mountain ranges and rivers all to scale. Punch described the attraction as "a geographical globule which the mind can take in at one swallow."[1] In the surrounding galleries were displays of Wyld's maps, globes and surveying equipment.
