Continuous induction is a thing!

Great question: A #precalc student is wondering about continuous induction – is this a thing? If so, how does it work? How do we define a 'next' step for a continuous set of numbers? How do you prove things about this 'next,' if so? Can proof by induction get done in this way? #MTBoS #iTeachmath […]

Motivation

My interest in any particular piece of mathematical content varies. There are some things that I think are just absolutely fascinating, others…nah. So I think if I was, at bottom, motivated by a love of mathematics then my teaching would ultimately suffer for it. Working with children, the future looms: I want these kids to […]

Is this math?

Look at those lines, that perspective, the symmetry…there is a clear sense of geometry in this picture, and if geometry is math (it is) then there’s a case to be made that this picture is mathematical. Hence the artist is a mathematician. So the picture is math. Except that’s not quite right, is it? It’s not fair […]

Mayyyybe

Beyond that, though, we’ve grown ever more aware of the problems with centralizing the internet. Traditional blogs might have swung out of favor, as we all discovered the benefits of social media and aggregating platforms, but we think they’re about to swing back in style, as we all discover the real costs and problems brought […]

I had a great conversation with Albert Brooks once. When I met him for the first time, I was kind of stammering. I said, you make movies, they live on forever. I just do these late-night shows, they get lost, they’re never seen again and who cares? And he looked at me and he said, […]

“Equity” is dead, long live equity

By the time organizations — even organizations whose work I really like — start using the language of equity to advertise their work, it’s a sign that we’ve overtaxed the latest bit of edu lingo. “Equity” is at that point in the edu fad life cycle; it’s beginning to mean just about anything. I don’t […]

Scattered thoughts about: Springsteen on Broadway

Here are some scattered thoughts: Springsteen always structures his shows into little mini-arcs, acts, cycles of songs, whatever you want to call it, and he does exactly the same thing here. So “Growin’ Up,” “My Hometown,” “My Father’s House” and “The Wish” are all about his childhood, birthplace, father and mother respectively. Then we get […]

Save Big Money at Menards

Do you know the Menards jingle? Two options: What? Of course I do! In other words, you’re either from the Chicago area or you’re not. I am, and as we’ve been visiting my parents this week I’ve had many chances to revisit that particular aspect of my childhood. More importantly, though: here are a few […]
