Charter school irregularities

Dear Colleagues,

Charter schools use public money but not always for the benefit of the students who go to these schools. Here is a particularly sad case:

Power of classification

Dear Friends, One of the things mathematics tries to do with definitions and taxonomy is to classify objects/concepts so that it is possible to tell when things are alike or different more easily. Classification often makes it possible to see patterns that would be hard to spot otherwise. We are all...

Gerrymandering in the news

Dear Colleagues, An American court recently argued that the district lines drawn by the legislature in North Carolina appeared to have been done for partisan reasons and blocked their implementation. More recently, the Supreme Court of the United States put aside that ruling meaning that in the upco...

Election methods

Dear Colleagues, Elections in which one votes for one's "favorite" candidate only and plurality (largest number of first place votes) is used to decide the winner often results in the election of an individual who is not favored by a majority of people. While alternate election systems are...

Topology and art

Dear Colleagues,

Some artists seem to be inspired by issues of curvature and topology. Toru Kurokawa's sculptures are perhaps partly inspired by topological issues. Whatever the inspiration very interesting forms.

Fields medal

Dear Colleagues, Many people view the Fields Medal as the most prestigious award in mathematics despite the fact that it does not carry a big monetary reward. One curious aspect about the Fields Medal is that in "recent" years it has been awarded to individuals who are at most 40 years of ...

Kidney exchange

Dear Colleagues, The number of people who need kidney transplants if very large compared with the number of kidneys available for transplantation. Furthermore, when a kidney becomes available often the people who are in most dire need of a transplant are not compatible with the available kidney for ...

Number of interviews in a matching market

Dear Colleagues, Many two sided markets use a system rooted in the ideas of David Gale and Lloyd Shapley to match the "males" and "females" who are the two sides of the market in a stable manner. However, efficiency is also a goal that one tries to achieve. In a widely studied se...

Hinged tesselation

Dear Colleagues,

You might enjoy thinking about various geometry questions based on viewing the hinged polygons shown here:

This item about hinged dissections might also be of interest.

More on gerrymandering

Dear Friends, Another contribution to mathematical ideas related to gerrymandering has been posted to the ArXiv. Again, the issue in gerrymandering is the practice of legislative bodies drawing district lines for the gain of a particular party or group of voters. https://arxiv.org/pdf/1801.02064.pdf...

Mathematics and gerrymandering

Dear Colleagues, It is fashionable in some mathematical circles to think that mathematics is a subject which grows only from looking at internal questions related to the development of the field. Certainly, there have been times when mathematics grew because questions arising outside of mathematics ...

Foundations of physics

Dear Colleagues, More or less, the theorems of mathematics stay theorems forever. However, in physics and the other sciences we have to change the way we view subjects as we learn more information that sometimes calls into question what we think we understand. Here is a paper that deals with some fo...

Unavoidable patterns in words (strings)

Dear Colleagues, There is a surprisingly rich theory in discrete mathematics of the study of strings - patterns of symbols taken from some alphabet, perhaps 0 and 1 or perhaps x, y, and z. Thus one can do algebra on strings by defining, by way of an example, an operation on two strings by juxtaposin...
