There are cartoons (and don't forgot to hover over them for extra content).
Including what may be the best cartoon of all time:
A 'What If' page where hypothetical physics questions are answered (did you know how many giraffes high a person can throw a ball?).
And a twitter feed that offers a host of interesting numbers and measurements:
6.5: Mass, in grams, of a kilometer-long strand of human hair
