Mechanical calculatorA mechanical calculator, or calculating machine, is a mechanical device used to perform the basic operations of arithmetic automatically, or (historically) a simulation such as an analog computer or a slide rule. Most mechanical calculators were comparable in size to small desktop computers and have been rendered obsolete by the advent of the electronic calculator and the digital computer. Surviving notes from Wilhelm Schickard in 1623 reveal that he designed and had built the earliest of the modern attempts at mechanizing calculation.

ChampagneChampagne (ʃæmˈpeɪn, ʃɑ̃paɲ) is a sparkling wine originated and produced in the Champagne wine region of France under the rules of the appellation, that demand specific vineyard practices, sourcing of grapes exclusively from designated places within it, specific grape-pressing methods and secondary fermentation of the wine in the bottle to cause carbonation. The grapes Pinot noir, Pinot meunier, and Chardonnay are used to produce almost all Champagne, but small amounts of Pinot blanc, Pinot gris (called Fromenteau in Champagne), Arbane, and Petit Meslier are vinified as well.
