Speaking of time, are you aware titanium was first discovered in Cornwall, Great Britain by William Gregor, the vicar in the Creed parish and amateur geologist in 1791? Gregor recognized the use of a new aspect in ilmenite when he found black sand with a stream inside nearby parish of Manaccan. It seemed the sand was attracted by the magnet, so Gregor analyzed the sand and determined the presence of two metal oxides: iron oxide and a whitish metallic oxide he couldn't identify. Realizing the unidentified oxide contained metallic that would not match any known elements, Gregor reported his findings on the Royal Geological Society of Cornwall and within the German science journal Crell's Annalen. Interestingly a few years later the oxide was independently discovered in 1795 by Prussian chemist Martin Heinrich Klaproth, of what we have now call Slovakia. Klaproth named the new element for that strong Titans in Greek mythology.
