Biased Algorithms

Dear Colleagues, We interact with many algorithms regularly when we interact with the Web. However, many algorithms don't treat all "users" the same. Here is an account of what is happening. https://www.technologyreview.com/s/608248/biased-algorithms-are-everywhere-and-no-one-seems-to-care...

School choice in NYC

Dear Colleagues, Here is a comment on the mechanics of the way school choice operates in New York City. The system involves a matching market where the slots available at the schools are given out to students who rank these schools as places they wish to attend. http://ncspe.tc.columbia.edu/center-n...

Maryam Mirzakhani, dies at 40

Dear Colleagues, I was shocked to learn that the Iranian born mathematician Maryam Mirzakhani, the first woman to win the Fields Medal has died at 40 years of age. Fields medal honorees must be under 40 to win the award. http://www.reuters.com/article/us-people-mirzakhani-idUSKBN1A00R3?il=0 Sadly, Joe

Convex polygons which tile the plane

Dear Colleagues, Which convex polygons tile the plane? After progress about this question throughout the 20th century, the remaining issue was which convex pentagons tiled the plane. Many infinite families were known but as recently as 2 years ago a new pentagon which tiled the plane was discovered....

Needing algebra and beyond

Dear Colleagues, By my standards, this http://blogs.edweek.org/edweek/top_performers/2017/07/for_applied_learning_to_work_a_national_effort_is_required.html discussion, while raising many important issues, is too generous to the status quo. With better material constituting the K-12 curriculum both ...

Tests are a big business

Dear Colleagues, Selling tests in America is a big business but one where many of the public schools which are forced to buy the tests would not have done so out of choice. Here are thoughts on this phenomenon: https://gadflyonthewallblog.wordpress.com/2017/04/08/standardized-testing-creates-captive...

Leaf atlas

Dear Colleagues, The shapes of leaves has always fascinated me -perhaps an off shoot of the fact that I call myself a geometer. While mathematics has given names to shapes using terms like rectangle, rhombus, Reuleaux triangle, etc., to describe the shape of a maple leaf, we say "shaped like a ...

Privatizing education

Dear Colleagues, Public education and separating the state from religion have been in my opinion heavily tied to democracy being a success in America.

Dear Colleagues,

SIAM has made available an updated edition of its brochure dealing with career opportunities in Applied Mathematics. It is very well done including human interest items of people who describe their own personal stories.

Algebra and college graduation

Dear Colleagues, The article below does not frame the issues of college algebra and "remediation" in the way I think is most helpful but it is nice that scrutiny is being paid to the issue of whether or not algebra is increasingly becoming a "gatekeeper" for college graduation. h...

Economics and computation

Dear Colleagues,

Alvin Roth called my attention via this posting to a conference on economics and computation. Just the range of titles makes fascinating reading:
