Patterns of Change – Calculus as a Critical Literacy
Stephen Downes’ introductory blog posting for the second week of the Critical Literacies Online Course ( CritLit2010 ) deals mainly with how we describe change, and in fact it would (with some minor edits) be the basis of a good … Continue reading
Why People Hate Mathematics and Atheists
Jason Green’s response to the readings for Week 1 of the Downes&Kop Critical Literacies course concludes with the question “how does one think critically without it coming across as a baseline of distrust?” I actually think that a “baseline of … Continue reading
LRB · Joseph Stiglitz · The NonExistent Hand
LRB · Joseph Stiglitz · The NonExistent Hand. One comment in particular rang a bell for me. Often the use of a mathematical model is considered as giving predictions greater credibility when all it really does is ensure that they … Continue reading
Have a Heart!
It is always interesting when a probability question produces a counterintuitive result, and the following “glimpse a heart” question is a wonderful example of that:

Born on a Blue Day
Coincidentally I read ‘Born on a Blue day’ just yesterday – i.e. one day before zac at squareCircleZ posted his summary review – (having been led to the order the book after watching a video posted – also at SqCZ … Continue reading
What is 0^0 equal to? – squareCircleZ
