Knowledge space theory (KST) provides a rigorous mathematical framework to represent an individual’s knowledge state as a collection of items or skills that have been mastered. This framework, which ...

Banach space theory is a central branch of modern functional analysis concerned with the properties of complete normed vector spaces. This area of mathematics encompasses the study of geometric ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

Embrace the flow, says a duo of mechanical engineers at North Carolina State University—the flow of energy, that is. The mantra you might normally hear from your yoga instructor could be an entirely ...

Fragments of energy may be the fundamental building blocks of the universe. The theory combines the ideas of particles and waves into a concentration of energy that flows throughout space and time.

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

Rising launch cadences have dramatically increased orbital debris, posing critical risks to spacecraft and operations, as highlighted by incidents like the Shenzhou-21 stranding. The primary barrier ...
