Three scientists won the 2023 Nobel Prize in physics for their work developing methods to shoot laser pulses that only last an attosecond, or a mind-bogglingly tiny fraction of a second.
The 2023 Nobel Prize in physics has been awarded “for experimental methods that generate attosecond pulses of light for the study of electron dynamics in matter”.

Quantum mechanics raised tough philosophical questions about the nature of the world – and a physicist named John Bell figured out how experiments could answer them.

Science fields are improving at being more inclusive. But explicit and implicit barriers still hold women back from advancing in the same numbers as men to the upper reaches of STEM academia.

Part of the 2021 Nobel Prize in Physics was awarded for work modeling Earth’s climate using its chaotic, complex weather. To scientists, chaos lies in the gray zone between randomness and predictability.

The Nobel Prize for physics was awarded to three scientists for the inventions of optical tweezers – in which two laser beams can hold a tiny object – and a method for creating powerful lasers.
Today’s scientific research is characterized by interdisciplinary, international collaboration. Awards like the Nobel Prizes haven’t caught up.

The 2017 Nobel Prize for Physics was awarded to scientists who helped pioneer the discovery of gravitational waves. Australia is playing an important role in gravitational-wave astronomy.
The Chalk River Laboratories in 2012. Canada’s role as a world leader in neutron-scattering is at risk because of a failure to invest in infrastructure renewal at the facility.

Canada is a world leader in the field of neutron scattering, winning a Nobel Prize in 1994 for its invention. But the looming shutdown of facilities at Chalk River puts us on the sidelines.
