Physicists have shown that Markov processes, widely used to model complex systems, must unfold over a larger space than previously assumed. Scientists believe that time is continuous, not discrete -- ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Researchers have developed a new analog photonic correlator that can be used to locate an object transmitting a radio signal. They demonstrated its ability to identify the location of a radio ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. If you want to learn what the Universe is made out of at a fundamental ...

For the first time, we have tracked a strange blast of radio waves – called a fast radio burst – back to its source, solving a major cosmic mystery. The burst came from a magnetar, which is a neutron ...
