Complexity theorists sort problems into categories, called complexity classes, based on the resource demands of the best algorithms for solving them — that is, the algorithms that run fastest or use ...

Theoretical computer scientists are always probing the relationship of space (memory) and time. For 50 years, experts knew that a calculation of X steps required X/log X memory slots, but a new ...

As we stand on the brink of a new era in technological complexity, our approach to safety and reliability must evolve just as rapidly.

Time and memory space are the two main constraints on what we can compute, and understanding their relationship is a key part of computational complexity research ...

Coronal mass ejections (CMEs) are the primary drivers of adverse space weather in the inner heliosphere. Interactions between CMEs and other interplanetary structures can significantly alter their ...

People have always taken space for granted. It is just emptiness, after all—a backdrop to everything else. Time, likewise, simply ticks on incessantly. But if physicists have learned anything ...

Aging fleets of airborne radar are giving way to a new era: in 2028, the U.S. Space Force will begin launching satellites that will be able to track cars and boats from space, to supply ground moving ...
