10-10 Celebrate Ada Lovelace day!

It’s Ada Lovelace day, celebrating the work of women in mathematics, science, technology and engineering. To join the celebration +Plus Magazine revisits a collection of interviews with female mathematicians produced earlier this year. The interviews accompany the Women of Mathematics photo exhibition, which celebrates female mathematicians from institutions throughout Europe. It was launched in Berlin in the summer of 2016 and is now touring European institutions.

To watch the interviews with the women or read the transcripts, and to see the portraits that featured in the exhibition, click on the links below. For more content by or about female mathematicians click here.

Probably more likely than probable – Reblog

This is a reblog from here Probably more likely than probable // Revolutions

What kind of probability are people talking about when they say something is “highly likely” or has “almost no chance”? The chart below, created by Reddit user zonination, visualizes the responses of 46 other Reddit users to “What probability would you assign to the phase: <phrase>” for various statements of probability. Each set of responses has been converted to a kernel destiny estimate and presented as a joyplot using R.

Probable

Somewhat surprisingly, the results from the Redditors hew quite closely to a similar study of 23 NATO intelligence officers in 2007. In that study, the officers — who were accustomed to reading intelligence reports with assertions of likelihood — were giving a similar task with the same descriptions of probability. The results, here presented as a dotplot, are quite similar.
