In memoriam
Remembering Professor Kostadinka Bizheva (“Dida”)
It is with great sadness that we acknowledge the passing of Kostadinka Bizheva, Professor in the Department of Physics and Astronomy, affectionately known as Dida to her colleagues and friends.
IQC and Waterloo mourn the loss of Raymond Laflamme
Raymond Laflamme, a trailblazer in quantum information processing and pioneer of IQC, died on June 19 after a lengthy battle with cancer.
Features
The woman behind the laser
Celebrating Dr. Donna Strickland's chirped pulse amplification breakthrough that has reshaped science, technology, and everyday life over the last 40 years.
What would you do if you woke up one day and your whole life changed?
Forty years ago, when Donna Strickland, physics professor at the University of Waterloo, and Gérard Mourou published their paper on the discovery of chirped pulse amplification (CPA), they knew they had found something that would change laser science.
Even black holes have bad hair days
New EHT images reveal unexpected polarization flips at M87* that are giving scientists insight into the year-by-year evolution of a supermassive black hole’s ring.
The Event Horizon Telescope (EHT) collaboration has unveiled new, detailed images of M87*, the supermassive black hole at the center of the galaxy M87, that reveal a dynamic environment with changing polarization patterns near the black hole.
The dark side of lava planets
A team of University of Waterloo researchers are shedding light on the darkest side of lava planets.
Lava planets may sound like science fiction, but they're very real for astrophysics professor Dr. Lisa Dang, who is studying them as a larger team of international researchers looking to further explore their inner workings.
A fond farewell to Instructor Jeff Gardiner
The Department of Physics and Astronomy is saying goodbye to Jeff Gardiner, one of its longest serving members, who heads into retirement in October.
Quantum computers learn how to simulate quarks
Waterloo researchers have developed a new quantum computing approach that brings science closer to simulating the early universe.
Researchers at University of Waterloo’s Institute for Quantum Computing (IQC) have reached a milestone in quantum information science: using a quantum computer to simulate how matter can behave in extreme environments, like the early universe after the big bang.
Will Percival named Royal Society of Canada Fellow
Dr. Will Percival, distinguished research chair in Astrophysics and director of the Waterloo Centre for Astrophysics, has been recognized as a 2025 Fellow of the Royal Society of Canada.
Meet our students
Graduating with a one-of-a-kind degree
Isabelle Marincic is the first University of Waterloo student to complete Honours Life Physics with a specialization in Biophysics and a double minor in Astrophysics and Earth Sciences.
Charting the quantum unknown
PhD student Sijia Wang explores the intersection of gravity, quantum mechanics, and information theory to illuminate the mysteries of quantum gravity.
Co-op student advances exoplanet research
Waterloo co-op student joins Caltech’s Exoplanet Technology Laboratory through a prestigious summer research program.
Mapping the universe just got easier
With new emulator, cosmologists can explore data faster than thought possible.
As the study of the universe evolves and the data sets get larger and more complex, a new breakthrough means researchers can analyze huge data sets with just a laptop and a few hours.

Fall 2025: A FemPhys Review
The fall term brings along a new cohort of young physicists. For the FemPhys team, this is always an exciting time as we prepare to welcome the incoming batch of first years. We collaborated with the Faculty of Science orientation team’s Successful Scientists event to introduce the incoming class to FemPhys.
The Rocket Lab That Almost Took Off... Literally
This semester the PhysClub did something a little different and hosted a three-part event series called the Rocket Chronicles. This adventure brought physics together with duct tape, clay and just the right amount of chaos to be a lot of fun!
MNS Society: Fall 2025 in Review
The Fall 2025 term was a vibrant and community-driven term for the MNS Society. With a diverse lineup of events that blended science, creativity, and connection, the term brought together students from across all years and programs with something for everyone. Here’s a closer look at the events that defined our term.
SIN bin
Can you solve it? The Sir Isaac Newton Exam, as we all know and love it, continues to offer challenging problems to high school students around the world. Flex your Physics brains with this problem from a past Sir Isaac Newton Exam!
2006, Problem 4
A block of mass m = 2.25kg is pushed against a vertical wall by a force F which makes an angle of 36.9 degrees to the horizontal. If the coefficient of static friction between the block and the wall is µs = 0.25 what is the minimum force necessary to keep the block statio0nary?
1999, Problem 2
Han Solo is holding a rope which is supporting Princess Leia, of mass 55 alistones (an alien unit of mass), 3 zons (an alien unit of length) above the ground as shown. Han, of mass 80 alistones, is holding onto his spaceship, the Millennium Falcon...
