567: potassium (K), iron (Fe), and tungsten (W) Jun 27, 2016

-
Many, if not most, of the chemical-symbols for elements on the periodic table make sense from an English-background, such as 'O' for 'oxygen' and 'Ti' for 'titanium'. There are a few, however, that share no common letters with the English names. 'K' stands for 'potassium' because of the Latin name, 'kalium', and likewise 'Fe' stands for 'iron' from the Latin 'ferrum' which interestingly was the word for 'iron' but also 'sword'. The 'W' for 'tungsten' does not come from Latin (or Greek), but instead from the German 'Wolfram'. The English name is adopted from the Swedish, literally 'heavy stone', though the German name, more scientific, comes from 'wolframite' where it was discovered, and means 'devourer of tin' because of its chemical properties.

Check out the latest podcast on the Patreon for as little as $1: • It is very easy for misinformation to spread so long as there is a grain of truth to it, such as the line of ' let them eat cake ', which was probably never said by Marie Antoinette. Another such disputed quote is "I return in 3 (or 5 or 8) days; don't wash" said by Napoleon to his wife Josephine. This quote is more likely to have been written than that attributed to Antoinette as he did often write her love letters, but many of the original lines from which the now-famous quote could have been drawn are often contradictory or not so reliable.

852: delilah Apr 8, 2017

Plenty of common Western names have some biblical relevance. It is usually from the frequency of these names that terms like 'john' referring to a man who hires prostitute, or foundation the baseball team, Yankees , come about. Some names, such as 'Delilah', are also used as nouns separate from the name, but with connotations stemming from Scripture, and not contemporary connotations. It is from the story of Samson and Delilah where the sense of the word as 'seductress' began, but the name was around for much longer than this. There is disagreement concerning the true etymology of this word, but it either comes from the Hebrew element 'dal' meaning 'weak' or the Hebrew for 'delight'. Unlike other much older names like 'Matthew' or 'John', 'Delilah' only started to be used as a name in the 17th century with the Puritans, though it gained more popularity following Saint-Saens' opera, Samson and Delilah (1877).
