Judging school effectiveness

Dear Colleagues, In cities where parents are allowed to use "choice" programs regarding where their children might go to school, rather than students being sent to a neighborhood school, the parents must have some basis on which to regard one school as being a better one for their child. T...

Replacing one paradox with another

Dear Colleagues, The Banach-Tarski Paradox, which suggests that the usual foundations of mathematics allow one to decompose a solid ball into parts and reassemble the parts into two solid balls congruent to the original, can be dealt with in a way that resolves this paradox but as the article below ...

Mastering Go without human input

Dear Colleagues, Games such as checkers, chess, and Go have a rich computational complexity. But as artificial intelligence has advanced software to play these games has reached the point were the software regular beats good human players. The software to play Go that achieved good results against h...

New definitons for scientific units of measurement

Dear Colleagues, When numbers are used in the real world for measurements such as 6.3 pounds or 7 miles one needs to have a "a standard yardstick" for such measurements. Thus, the definition of a kilogram is related to a physical object in a vault and that physical object might change its ...

"Ethical behavior" of driverless cars

Dear Colleagues, When humans drive we are often faced with "ethical" decisions about what to do in an emergency. Do we take an action that will kill ourselves with probability .9 or a different action which will kill 100 people with probability .1? This article address how the algorithms t...

Euler's impact on Riemann

Dear Colleagues, Most mathematics is built on ideas from earlier scholars. No one doubts the importance of Euler in the history of mathematics but one does not always think of his work as influencing Riemann in particular. Here is a look at ways in which what interested Riemann has its roots with Eu...

Detecting gerrymandering

Dear Colleagues, Much attention has been paid recently to gerrymandering and how to detect that it is being done. The Supreme Court is considering a case of "political gerrymandering" and whether the Supreme Court should monitor redistricting plans produced by highly partisan legislatures....

Richard Thaler wins the Nobel Memorial Prize in Economics

Dear Colleagues, The Nobel Memorial Prize in Economics has been awarded to Richard Thaler (economist at the University of Chicago) for his work in behavioral economics. Many approaches to economics build models based on the assumption that humans behave "rationally." Thaler's work builds o...

Phase transition

Dear Colleagues, Attempts to model our universe and its origins still engage physicists, mathematical physicists, and mathematicians. While the catchy phrase "big bang," may garner a lot of attention, there are those who see what happened as a "phase" transition! http://nautil.us...

Repeat voting

Dear Colleagues, The game theorist Sergiu Hart recently has proposed the idea of voting done in two rounds where before the second round is carried out the voters know the results of the first round for long enough to think through the implications. The idea is that people who perhaps did not realiz...

Historical sources - Catalan numbers

Dear Colleague, Many educators are looking at historical sources as an entry point to mathematics. This essay is an example of a discussion of an historical source used to look at the way that the Catalan numbers can be used to count triangulations of a convex polygon, where one has to set up rules ...
