Scientists have announced the results of a decade-long quest to measure Newton’s gravitational constant, the force that keeps our feet on the ground and holds planets in orbit. The pursuit was more or ...

The cosmological constant is the mathematical description of the energy that drives the ever-accelerating expansion of the cosmos. It's also the source of one of the most enduring and confounding ...

Ground motion models (GMMs) are an essential component of probabilistic seismic hazard analysis (PSHA), providing quantitative tools for estimating ground motion intensities (e.g., peak ground ...

The macOS Tahoe 26.4 and iPadOS 26.4 betas that Apple released today reintroduce a compact Safari Tab Bar option for those who prefer that view option. Apple removed the compact tab bar option with ...

Happy weekend! Look, I know New Year’s resolutions are a cliché, but I want to share mine with you: This year, I’m going to finish my thesis. I completed coursework for my master’s degree in Art ...

Astronomers are rethinking one of cosmology’s biggest mysteries: dark energy. New findings show that evolving dark energy models, tied to ultra-light axion particles, may better fit the universe’s ...

If you’re looking for one of the best tablets, you’ll almost certainly be considering either the best iPad or one of the best tablets from Samsung or OnePlus. Chief among the best Android tablets is ...

Samsung's new flagship Android tablet line retains the 14.6-inch Tab S11 Ultra, but is joined by an 11-inch option. Both have upgraded processors and slimmer designs. Executive Editor David Carnoy has ...

In physics, we have a bunch of constants that are used in models to explain how the world works. These are fixed numbers that we plug into equations along with our variables. For example, the ...

It's fun to think about the fundamental physical constants. These are special values used in our models of the physical universe. They include things like the speed of light, the gravitational ...

Planck’s constant is one of the most important numbers in all of physics. It is, essentially, the ultimate guide to the quantum world. It tells us where quantum effects are important, the fundamental ...
