Hawking’s most famous book, A Brief History of Time, sold 10 million copies and was translated into 40 languages, skyrocketing to the top of the bestseller lists in the US and UK.
By figuring out fission, physicists were able to split uranium atoms and release massive amounts of energy. This Manhattan Project work paved the way both for atomic bombs and nuclear power reactors.
Looking up in the main chamber at SNOLAB’s facility in the Vale Creighton nickel mine in Sudbury, Ont., a giant spherical neutrino sensor array the size of a 10 storey building is used to detect subatomic particles that pass through the earth.

Ig Nobels reward research that first makes you laugh and then makes you think. Investigating the internet meme of fluid felines fits the bill – and adds to the physics field of rheology.
Cosmologists are heading back to their chalkboards as the experiments designed to figure out what this unknown 84 percent of our universe actually is come up empty.

A LIGO team member describes how the detection of a gravitational wave from a new source – merging neutron stars – vaults astronomy into a new era of ‘multi-messenger’ observations.

The gravitational wave itself is the least exciting part of the announcement from LIGO and Virgo. Observing this new source answers many longstanding questions.
Without satellites, modern technologies such mobiles phones and GPS would not exist.

The affective domain - motivation, interest and values and their inter-relationships - forms an integral component in facilitating learners’ construction of physics knowledge.
Evidence shows that otherwise high-performing female students under-perform compared to their male peers on certain questions in physics. We don’t know why.
