## The Science of Moving Dots

A guest post by Allison Kotleba:

When most people think of basketball, they picture the tall players, the fast-paced plays, and the seemingly impossible shooting skills. However, spatiotemporal pattern recognition does not come to most people’s minds when discussing the game. In his Ted Talk titled The Math Behind Basketball’s Wildest Moves, Rajiv Maheswaran discusses the use of spatiotemporal pattern recognition in analyzing the players’ movements and using this analysis to help coaches and players create effective game strategies. This up-and-coming science aims to understand and to find patterns, meaning, and insight in all of the movement in our world today.

## What is a Manifold? (5/6)

In our last post, we invented a new geometry by re-scaling the inner product of the usual Euclidean plane. This modification did not change any of the angles in our geometry, in the sense that if two curves intersected in a particular Euclidean angle, then in our new geometry they still intersected in the same angle. However, distances and areas had shrunk and had done so significantly at points away from the origin. For instance, we found that the total area of the plane under our new metric was $\pi$ – a finite value.

## A Letter From the Editors on the Executive Order on Immigration

In editing the AMS Graduate Student Blog, we hope to provide a platform for discussion about issues that affect and are important to the lives of graduate students. At times, this has meant publishing pieces that grapple with complicated and complex topics including sexism, diversity, and discrimination, both in academia and in our communities at large.

That said, until now we have never taken a specific political stance on an issue, nor called for our audience to do the same. However, in light of President Trump’s recent executive order placing immigration and travel restrictions on individuals from Iran, Iraq, Syria, Sudan, Yemen, Libya, and Somalia, we feel that there are certain issues that are too important not to take a vocal and principled stand against.

We, the editorial board of the AMS Graduate Student Blog, condemn—in the strongest possible terms—these actions by President Trump, and we ask that he repeal this executive order as soon as possible. Moreover, we implore our readers, our fellow graduate students, and the entire mathematical community to stand up with us and other protesters around the world in condemning the president’s actions and demanding change.

## Using Groupworthy Tasks to Increase Student Engagement

There has been an ongoing call in mathematics education for students to be engaging in problem solving and collaborative groupwork.  Although, many instructors find that when they put students in groups, some students seem disengaged and we may start to worry that groupwork is not nearly as motivating or interesting to students as we might expect.  A natural response at this point is to blame the student for their lack of engagement.  But, as Alfie Kohn, an author who writes extensively about education and student motivation, often states, “When students are off task, our first response should be to ask: What’s the task?”  Indeed, this is one of the key elements to engaging students in the mathematics classroom; we need to design a good task.

## Up to Date Blog Content for JMM 2017

Looking for blog content about the 2017 Joint Mathematics Meetings? Check out the JMM 2017 Blog where you can catch up on yesterday’s main events and keep up with some of the main events during the meeting. I really enjoyed reading Profession, State of since I couldn’t attend the full panel discussion but I can still hear the ideas for increasing diversity in the professions from the awesome set of panelists.

Some of the posts are done live so attendees can jump in on events while they happen. Other posts are done after the event which allows the authors to give more of an overview of everything that occurred.
