Final Oreo Post

Part 1 and Part 2. There have been a couple of questions regarding the validity of my measuring process. The one that irked me the most was the fact that I had never measured the weight of the wafers of the Double Stuf. Was it possible that the wafers for the Oreo and Double Stuf […]

Oreo Verification

So things have gone a bit crazy lately. While on summer vacation, this happened: All for a blog post that I wrote in February. (My previous high for views in one day was 299.) In the original post where my class suggests that the Double Stuf Oreo is only 1.86x stuffed, the data set is […]

Timon on

Here’s part of his take on Dan Meyer’s 101qs site: Over at Dan’s site people have been discussing these last set of questions and we find, naturally, Dan promoting his brand of “Make the prompt scream the question you are […]

Follow-up to 25 billion apps

Follow-up to 25 billion apps. Our class calculated that the app store would hit 25 billion on Friday at 11pm eastern. The contest is over, but the press release didn’t say when it finished. The 25 billionth app downloaded, Where’s My Water? Free, was downloaded by Chunli Fu of Qingdao, China. As the winner of the App Store Countdown […]
