'Al-ooo-min-ee-um'. Not 'al-oom-in-um' as I was used to.
Turns out that there's a very good reason for this difference, which is explained by my current book:
The confusion over the aluminum/aluminium spelling arose because of some indecisiveness on [the discovering chemists] part. When he first isolated the element in 1808, he called it alumium. for some reason he thought better of that and changed it to aluminum four years later. Americans adopted the new term, but many British users disliked aluminum, pointing out that it disrupted the -ium pattern established by sodium, calcium, and strontium, so they added a vowel and syllable.
