Mathematics is considered a universal language, and is present in virtually all cultures and places. It is the study of topics such as quantity, structure, space, and change. Math is a part of every moment of our lives. As Tom Lehrer famously postulates,
How much gold can you hold in an elephant's ear?
When it's noon on the moon, then what time is it here?
If you could count for a year, would you get to infinity,
Or somewhere in that vicinity?
If numbers are your thing, consider a project based around Mathematics.
