To capture higher-definition and sharper images of cosmological objects, astronomers sometimes combine the data collected by several telescopes. This approach, known as long-baseline interferometry, ...

From the Department of Bizarre Anomalies: Microsoft has suppressed an unexplained anomaly on its network that was routing traffic destined to example.com—a domain reserved for testing purposes—to a ...

Abstract: Passive seismic interferometry is a vastly generalized blind deconvolution question, where different paths through the Earth correspond to different channels called Green’s functions; the ...

Ten years ago, astronomers made an epic discovery with the Laser Interferometer Gravitational-Wave Observatory. Cosmology hasn’t been the same since, and it might not stay that way much longer. Out ...

The relentless pursuit of higher precision in semiconductor lithography and atomic-scale manufacturing demands measurement systems capable of sub-nanometer accuracy, multi-axis capability, and robust ...

Faster computer and electronic processors require smaller features for integrated circuits (IC), which in turn require smaller and smoother substrate surfaces. Chemical mechanical polishing (CMP) has ...

We explore the principles, implementation details, and performance characteristics of a lensless multi-spectral digital holographic sensor and demonstrate its potential for quality assurance in ...

Ahead of the November presidential election, just 19% of Americans say democracy in the United States is a good example for other countries to follow, according to a Pew Research Center survey ...

NASA announced Friday that it will award contracts to seven companies, including SpaceX and Blue Origin, to study how to transport rock samples from Mars more cheaply back to Earth. The space agency ...
