A historical collection of our writing.
At the end of last year before going away for the holidays, I laid out a miniature program for learning / teaching about rates of change. The first step was to appreciate the tremendous difference between linear and exponential change. It is easy to write down the relevant definitions: in linear […] Read more (opens Continuations in a new tab)
Last year’s Tech Tuesday ended with a first look at computational complexity. We saw how crazily long a brute force attempt to find a 40 character string would take. This was the result of exponential growth in the runtime of our algorithm. Today we will start to dig a bit deeper. Let’s consider a […] Read more (opens Continuations in a new tab)
Belated Happy New Year everyone. Today I am traveling back to New York – weather and air traffic permitting – after a great family ski vacation in Colorado. As announced at the end of last year I took a break from (most) email and also largely from social media, other than occasionally looking at […] Read more (opens Continuations in a new tab)
This will most likely be my last blog post for the year. I am planning to take off a couple weeks not just from writing but also from spending pretty much any time online. During this time I look forward to reading a number of books that have piled up in my queue (both non-fiction […] Read more (opens Continuations in a new tab)

On Saturday evening, close to the height of the storm I had to go to the Upper East Side […] Read more (opens Continuations in a new tab)
In case you come here only on Wednesdays when I write about homeschooling, you might also want to check out Tech Tuesdays (a series that goes back several years). In yesterday’s Tech Tuesday I wrote about computational complexity and gave an example of a program that would take hundreds of […] Read more (opens Continuations in a new tab)
