THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...

This note presents models for mixture-amount experiments when the total amount takes a zero value. These models modify those of Piepel and Cornell (1985), which are ...

Keywords: Molten salt, pebble-bed reactors; graphite reflector; annular tanks; seismic behavior; fluid-structure interaction; base isolation; design recommendations. Abstract: This report describes ...

When a spacecraft enters a thick atmosphere at a high velocity, it rapidly compresses the gas in front of it. This creates temperatures high enough to ionize the gas molecules into a hot, dense plasma ...

How did science get started? A few years back, we looked at one answer to that question in the form of a book called The Invention of Science. In it, British historian David Wootton places the origin ...

To investigate the extent to which LLMs respond in ways that are aligned with the altruistic behaviors observed in humans, Johnson and Obradovich designed a simulated behavioral science experiment.
