Weather, which changes day-to-day due to constant fluctuations in the atmosphere, and climate, which varies over decades, are familiar. More recently, a third regime, called “macroweather,” has been used to describe the relatively stable regime between weather and climate.
McGill University physicist Aashish Clerk and epidemiologist Madhukar Pai are among the inaugural members named today to the Royal Society of Canada’s College of New Scholars, Artists and Scientists.
A new network that is bringing together expertise from universities, government and industry is implementing a new vision for training the next generation of medical physicists. Ultrasounds, X-rays, MRIs and nuclear medicine are only a few examples of the essential contributions of medical physicists. The field of medical physics applies the principles of physics to medicine, from diagnosis to treatment, and seeks to quickly transform scientific discovery into clinical applications. Medical physicists are also clinical health care professionals providing service in fields such as radiation therapy, medical imaging, nuclear medicine or radiation protection, to name a few.
While short-term weather is notoriously volatile, climate is thought to represent a kind of average weather pattern over a long period of time. This dichotomy provides the analytical framework for scientific thinking about atmospheric variability, including climate change.
To build the computer chips of the future, designers will need to understand how an electrical charge behaves when it is confined to metal wires only a few atom-widths in diameter.
A research team led by McGill University Physics Prof. Alexander Maloney is among the winners of the New Frontiers in Astronomy & Cosmology International Grant and Essay Competition who will present their winning proposals and essays in a joint conference Oct. 12 and 13 at the Franklin Institute in Philadelphia.
