Last Wednesday, we had some of the most interesting talks around Data Science, Machine Learning and Non Profits. For the purpose of providing a panorama of non profits, we included Universities, Foundations, NGOs and an Open Source project. And it is no wonder that they are non profits, they tackle the hardest challenges in Data Science and Machine Learning.We first heard Paul Duan, the founder of BayesImpact.org, a YCombinator-backed non profit. His presentation is here.Paul presented how they

11:31 PM | Making Math Fun

I was a math major from undergrad to doctorate, so obviously I think math is fun. Equally obvious to me (especially after teaching a variety of mathematical topics to college students), not everyone shares that opinion, which is too bad. Recently, though, I came across an organization devoted to making math fun for small children, and I wanted to share the link: Bedtime MathBedtime Math provides a variety of resources for introducing children to math in a fun way. The organization's name comes […]

Here is the fifth instalment in the Peter Grant (or Rivers of London) series by Ben Aaronovitch. Thus entitled Foxglove summer, which meaning only became clear (to me) by the end of the book. I found it in my mailbox upon arrival in Warwick last Sunday. And rushed through the book during evenings, insomnia breaks […]

10:03 PM | Documenting a class-participation activity

Contrary to popular belief, Ontario’s students are actually quite good at basic math: David Reevely:The solution to Ontario’s slipping math scores is more math time in the classroom, says the province’s education minister — both for students and for the teachers who instruct them. But Liz Sandals wants parents to know something that might surprise them: The province’s young people are actually quite good at basic math skills.

Chicks Might Map Numbers From Left To Right – Just Like Us!: Robbie Gonzalez:When you think of the numbers 1–10, you probably envision them running along a line, with 1 on the left and 10 on the right. Scientists have long debated whether this tendency is hardwired or culturally instilled. This week, the hardwired camp scored a major point. Young chickens, it seems, also map numbers from left to right.

The statistical rumble over the fumble continues.

Above is the histogram of fumbles per play (the reciprocal of plays per fumble in the first analysis). The New England Patriots are still separated, now on the left, from the rest of the […]

Stupiti che 1 non sia primo? Scopriamo insieme perché è "solo" l'unità!Abbiamo già visto come, partendo dai numeri primi, si possa sviluppare un discorso più o meno approfondito sulle fondamenta matematiche. Altrettanto fondamentale, però, si rivela provare a rispondere alla domanda su quale sia il numero primo più piccolo. E', infatti, abbastanza noto come il numero 1 sia stato ora inserito ora escluso dalla lista dei numeri primi, ottenendo in alcuni casi lo status di più piccolo tra […]
