I love teaching the liberal arts mathematics courses! They allow me to explore all sorts of ideas with my students. We're in a geometry unit right now and exploring different ways of defining dimension. As part of their homework I asked if they thought time travel would ever be possible (time sometimes being considered a fourth dimension). As I sit here grading the homework now I see a 50-50 split between those who think it will and those who think it will not.
The next question is about whether they would travel to the past or the future if time travel ever did become possible. I'm getting a lot of interesting answers - again, about a 50-50 split - many people saying they would go to the past and avoid the mistakes they had made. But I think my favorite answer this year is the following:
"I would travel back to the 1980's. I have always loved 80s culture and am kinda bitter I was only around for 3 years of it."
WOW! Given a choice of ANY era from past or future, this person would go to the decade I spent my high school and college years in. I had no idea how good I had it!!
