laterally

"The pedalling feels very different and the overall sensations of moving on the water, either laterally or vertically, is wildly different from any kind of cycling," Lambie says.

When you punch a nonauxetic material, it gets thinner and expands laterally.

The maneuver is a foundational element of the Atlanta style, where a skater crosses feet laterally in sync with the music.

"According to beam theory, when you bend a blade-like structure laterally sideways in the direction of their narrower dimension, they are quite a lot weaker compared to the main direction of strength," Tseng said.

The blades are also more wildlife-friendly: because they rotate laterally, rather than slicing down from above, they are easier for birds to avoid.
