• We had a good discussion of Interesting Numbers, including a reference to The Incredibles. See "The Incredibles- If Everyone Is Special, No One Is," Lessons from the Mouse blog (2017).:

On the car ride home, Dash says “Our powers make us special,” to which Helen (Mrs. Incredible) says, “Everyone is special, Dash”. Dash retorts back to her, “Which is another way of saying that no one is.” This is not just the opinion of a frustrated little boy, he is parroting the frustrations of his father who later on is arguing that a 4th grade graduation ceremony is silly (in his words, psychotic) because, “They keep celebrating new ways to celebrate mediocrity, but if someone is genuinely exceptional, they shut him down because they don’t want everyone else to feel back!” And lastly, this theme comes to a head when Syndrome is planning on giving everyone superpowers with his tech and claiming, “When everyone is super, no one will be.” ... Not everyone is special, understand, everyone is important, everyone is valid, and everyone is even significant, but not everyone is special.

• "Per centum": for each 100, in Latin.
