Dear Colleagues,

It is well known that any shape triangle can be used to tile the plane. What about using more "general" collections of triangles?

This recent interesting paper addresses a question of this type:

### Game theory approaches to gerrymandering

Dear Colleagues, Because the Supreme Court is looking into the issue of political aspects of gerrymandering, there has also been lots of scholarly interest in the issue of drawing legislative districts fairly. Here is an account of how some game theory thinking is being used to get "fair" ...

### Shell structures in architecture

Dear Colleagues, Modern engineering, supported by mathematics and computer science, has made it possible for architects to use forms in their buildings that would not have been possible 100 years ago. Here is one look at this phenomenon in the area of using "shells." https://link.springer....

### Gerrymandering

Dear Colleagues, Gerrymandering has been used by political parties in power to get more seats for their party both in state elections and elections for members of the House of Representatives. The Supreme Court probably in the current session will make a decision of some of what has happened. Comput...

### Moscow mathematics

Dear Colleagues, In the early 20th century many achievements of the Russian mathematics community were obscured due to the fact that lots of the work published in Russian was not easily read elsewhere, and later the Cold War contributed to these achievements not always being properly viewed. Here is...

### Ways of viewing quantum mechanics

Dear Colleagues, Some of the ways of thinking about quantum mechanics seem "paradoxical." A recent article tries to show that an approach to quantum mechanics due to Julian Schwinger may put the "foundations" of quantum mechanics in a more palatable form. https://arxiv.org/ftp/ar...

### Huge genome

Dear Colleagues, Yes, the human genome is complex but the genome of "wheat" is much more complex. And what about the genetic variation between different kinds of wheat? An improved version of the "wheat" genome has been completed: https://www.nature.com/news/small-group-scoops-in...

### Simpson's paradox

Dear Colleagues, Simpson's paradox calls attention to the fact that a "trend" when looking at a whole group may not hold for subgroups of the whole group - in fact one may see "opposite" behavior in the two subgroups that make up a group from what one sees in the group. Examples ...
