I will explain what the NUFFT is, some applications in science and engineering, and what happens “under the hood” in our new implementation. This includes a simpler spreading kernel that accelerates runtimes for the same accuracy, while preserving rigorous error analysis. I will also sketch some software issues. Along the way we will discover how the nationally known bluegrass fiddler Tex Logan fits into the story.

The talk will be accessible to 1st-year graduate students and advanced math majors.

Joint work with Jeremy Magland.
