This is the mathematical code which encapsulates in a snapshot the entire theory of general relativity. It represents sixteen equations (six of them duplicates) which define the nature of space, light ...

Flexible orientation through any environment requires a sense of current relative heading that is updated based on self-motion. Global external cues originating from the sky or the earth‘s magnetic ...

Which geometric shape has the highest possible dimensionless speed remains an intriguing unsolved problem in hydrodynamics, although in practice additional constraints (minimum material thickness, ...

Event-based sensing, i.e., the asynchronous detection of luminance changes, promises low-energy, high dynamic range, and sparse sensing. This stands in contrast to whole image frame-wise acquisition ...

Most foot-propelled swimming birds sweep their webbed feet backwards in a curved path that lies in a plane aligned with the swimming direction. When the foot passes the most outward position, near the ...
