Science exhibits, an interactive light show, and a joyful celebration of physics drew people from all walks of life to Perimeter Institute over the weekend.

septembre 23, 2025

Perimeter Institute opened its doors to nearly 2,000 community members over the weekend in celebration of 25 years of discovery. On Saturday and Sunday, September 20 and 21, 2025, members of the public attended PI/25: A Peek Inside the Perimeter, put on with support from the Stavros Niarchos Foundation, the presenting sponsor, and educational outreach champions Cowan and Toyota Motor Manufacturing Canada.

 

Guests had an opportunity to engage with hands-on science activities for all ages, put on by Perimeter Institute’s award-winning educational outreach team. Perimeter scientists were on hand too, to bring their research and a love of science to everyone who visited.

 

Many of the exhibits were put on in partnerships with Perimeter Institute’s partners in the Canadian science and technology space, including the University of Waterloo’s Science Outreach and Let’s Talk Science, who set up a junior scientist area for the youngest explorers. 

 

The Institute for Quantum Computing hosted an exhibit on quantum matter, and taught the basics of superconductivity with a levitating train. Exhibits highlighting ferrofluids, particle physics and black holes were on loan from the Ontario Science Centre.  

 

Hundreds of guests also gathered in Perimeter’s theatre for the debut of an original play, A Quantum of Hope, authored by Perimeter Institute alumni.

 

On Saturday evening, Perimeter’s iconic building lit up the night sky as a proud partner of Waterloo’s Lumen Festival, an annual event that brings light, art, and technology together. The art installation, ‘Say What You Will,’ transformed spoken word into light through voice activation from the audience. Each voice input was analyzed for its emotional tone and sonic qualities, and then transformed into a unique abstract animation projected onto the Institute’s façade.  
Visitors walked through a quarter-century of breakthroughs at Perimeter Institute, with displays featuring the Institute's biggest contributions to science across nine distinct research areas. A detailed version of the 'Turning Points' display is available on Perimeter's website.


Perimeter would like to thank all of the sponsors and partners that made this weekend possible, including Chartwells Campus Clean, the City of Waterloo, Doors Open, the Region of Waterloo, Scotiabank and the University of Waterloo.

The celebrations continue throughout the week as part of Perimeter Institute’s 25th anniversary. 

À propos de l’IP

L'Institut Périmètre est le plus grand centre de recherche en physique théorique au monde. Fondé en 1999, cet institut indépendant vise à favoriser les percées dans la compréhension fondamentale de notre univers, des plus infimes particules au cosmos tout entier. Les recherches effectuées à l’Institut Périmètre reposent sur l'idée que la science fondamentale fait progresser le savoir humain et catalyse l'innovation, et que la physique théorique d'aujourd'hui est la technologie de demain. Situé dans la région de Waterloo, cet établissement sans but lucratif met de l'avant un partenariat public-privé unique en son genre avec entre autres les gouvernements de l'Ontario et du Canada. Il facilite la recherche de pointe, forme la prochaine génération de pionniers de la science et communique le pouvoir de la physique grâce à des programmes primés d'éducation et de vulgarisation.
