## Why the Museum of Science chose algorithm

You might think algorithms are reserved for complex computer instructions, but if you've ever followed a recipe when you cook, then you have used an algorithm. To learn more, watch this video from award-winning science communicator Maynard Okereke, better known as the Hip Hop M.D.

Algorithm is a variant of algorism and ultimately comes from Arabic al-Khwārizmī, which refers to the 9th-century mathematician Muḥammad ibn Mūsā al-Khwārizmī. In this name, Khwārizm refers to an area of Central Asia now divided between Turkmenistan and Uzbekistan. Algorism became algorithm because of the influence of Ancient Greek arithmós, “number,” as in arithmetic. Algorithm was first recorded in English in the 1690s.

# zaffer

[ zaf-er ] [ ˈzæf ər ] Show IPA Phonetic Respelling

noun

an artificial mixture, resembling smalt, containing cobalt oxide and, usually, silica, used to produce a blue color in glass and in ceramic glazes.

For the origin of zaffer, “a cobalt oxide–silica mixture used to produce a blue color,” let’s travel down a linguistic rabbit hole. Zaffer, from French safre or Italian zaffera, may come from Arabic ’aṣfar, “yellow,” which resembles but is not related to saffron and sulfur. Alternatively, zaffer may come from Latin sapphīra, “sapphire,” via Ancient Greek sáppheiros, “lapis lazuli,” from a Semitic source akin to Hebrew sappīr, “sapphire.” One intriguing proposal is that sappīr and its close Semitic relatives come from Sanskrit śanipuriya, “dear to Saturn,” equivalent to Śani, the planet Saturn, plus priyá-, “dear.” Zaffer was first recorded in English circa 1660.

EXAMPLE OF ZAFFER USED IN A SENTENCE

The glass blower used zaffer to make the vase a beautiful hue of azure.
