There are some mathematical concepts that seem straightforward but make less and less sense the deeper you dig. Transcendental numbers are one of 'em -- but what the hell are they?
This video seeks to explain it. Essentially, it's a quality that means numbers like Pi can't be constructed properly using normal algebra. But, at this point, it makes sense to hand over to Simon Pampena, Australia's Numeracy Ambassador, who can do a much better job of explaining things. [YouTube]
