The Grand Quadratic Formula Quiz!

Simon has been pondering a lot about various ways to visualize or prove the quadratic formula.

He eventually came up with a 4-meter-long quiz sheet, slowly revealing the logic behind the quadratic formula as one solves the 9 problems one by one. Simon borrowed the actual problems from but reworded some of them to match his personal style, writing all of them down in his beautiful handwriting on large sheets of paper taped together to form a road to the quadratic formula. The answers were hidden under crafty paper flaps. We had a lot of fun traveling down this rabbit hole as a family, Neva stuck around solving the tasks until half-way through.

It took Simon two days to make the quiz
He covered the questions with extra sheets of paper and removed them as we solved the problems one by one.

Analysis and generation of text-based data. What else to do on vacation?

During the vacation, Simon worked on several programming projects playing with language and grammar, from Daniel Shiffman’s Programming from A to Z course at New York University. Those included creating a new context free grammar sentence generator, using a markov chain in a Google form, creating a diastic machine with JQuery and making a regular expressions tester in JavaScript.

I think I’m writing in a fixed width font

Simon was doing sentence analysis (something that he quite likes), but this time it involved writing (and he hates physical writing). Even though he has been writing since age 3 and enjoyed teaching himself most beautiful fonts and cursives at ages 4 and 5, he currently hates writing things down and prefers typing, getting impressively quick on both qwerty and azerty keyboards. While toiling away with his exhausting worksheet today he mumbled: “I think I’m writing in a fixed width font. That’s also called a monospace font sometimes”. I laughed and put down what he said, because it sounded really funny in that context. He brightened up at my interest, got up and gave me a sudden presentation about the 5 kinds of fonts: Sans-Serif (normal fonts without serifs, such as Arial or Helvetica), Serif (like Times New Roman or Georgia), Monospace (or fixed width fonts), Cursive (to emulate handwriting) and Fantasy (fonts for decoration, like Impact). He then got back to his worksheet. This way we sort of teach each other.
