Physics experiments have changed the world irrevocably, altering our reality and enabling us to take gigantic leaps in technology. From ancient times to now, here's a look at some of the greatest ...

Physics is supposed to be predictable. Drop a ball, and gravity pulls it down. Heat water, and it boils. Light travels in straight lines. Yet throughout history, scientists have encountered ...

No one can question the impact of science on human civilization, and the importance of experimentation in science is equally undeniable. Some experiments confirm what we already know, others suggest a ...

Quantum physics is the realm of the strange. And one of the strangest discoveries in the field is also one of the most fundamental: Particles fired at barriers with two slits in them can act like ...

The most beautiful experiment in physics, according to a poll of Physics World readers, is the interference of single electrons in a Young’s double slit. Robert P Crease reports Simply beautiful – the ...

Astronomers can't see dark matter directly, but they know it's there: Its gravity shapes galaxies and the large-scale ...

For most stars, neutron stars and black holes are their final resting places. When a supergiant star runs out of fuel, it expands and then rapidly collapses on itself. This act creates a neutron ...

The Matter of Everything tells the history of physics through experiments. Any book about the history of science for a general audience will, of necessity, be something of a distortion. The question ...

Physics is filled with mysteries - and believe it or not, gravity remains one of them. We rely on gravity to explain things large and small. And yet, at a fundamental level, we still don’t fully ...

College professors these days face an ever-higher bar to grab the attention of their students, forced to compete with the stimuli of smartphones and laptops in large lecture halls. But when your ...
