We tend not to dwell on the fact that we exist in three dimensions. Forwards-back, left-right, up-down; these are the axes on which we navigate the world. When we try to imagine something else, it ...

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 ...

In physics, breakthroughs are rare. Experiments are slow, expensive and often end up refining, rather than rewriting, our understanding of the universe. But what if the only constraint on scientific ...

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 ...

The original version of this story appeared in Quanta Magazine. There are precision measurements, and then there’s the Laser Interferometer Gravitational-Wave Observatory. In each of LIGO’s twin ...

Physics, especially the part about forces and motion, often feels like a maze of confusing concepts and formulas. If you’ve ever stared at a problem about an object moving or a force acting and ...

Arduino is transforming physics education by making concepts interactive and hands-on. Students can explore motion, electromagnetism, and energy transfer through real experiments using sensors and ...

Scientific discovery doesn’t always require a high-tech laboratory or a hefty budget. Many people have a first-rate lab right in their own homes – their kitchen. The kitchen offers plenty of ...

Physical-collapse theories have long offered a natural solution to the central mystery of the quantum world. But a series of increasingly precise experiments are making them untenable. How does ...
