The rare moment when all three Norths align
Explore the mathematical complexity behind a rare phenomenon where magnetic, grid, and true north align. This video examines the shifting relationship between these directional lines and the specific way they intersect.
The video delves into the mechanics of how different definitions of North interact. It specifically highlights the behavior of a diagonal line as it crosses the 2° line, noting a distinct difference in how the slope moves depending on whether one is measuring magnetic-vs-grid or magnetic-vs-true north. This creates a mirror image effect in the visual representation of the data.
