Working memory, math performance, and math anxiety.

The cognitive literature now shows how critically math performance depends on working memory, for any form of arithmetic and math that involves processes beyond simple memory retrieval. The psychometric literature is also very clear on the global consequences of mathematics anxiety. People who are highly math anxious avoid math: They avoid elective coursework in math, both in high school and co...

Imaging arithmetic: physics U math > physics + math

For several real-world problems, signal processing approaches are most successful when they combine the insight offered by the physics underlying the problem with the mathematical framework and tools inherent in digital signal processing. Imaging systems are a particularly fertile ground for problems in this class because they deal specifically with the capture of physical scenes and with the r...
