Take a self-guided tour from quantum to cosmos!

Welcome inside the Perimeter

There’s a universe of ideas to explore – from quantum to cosmos – at

The late Carl Sagan championed the power of science to further humanity. “I believe that in every person is a kind of circuit which resonates to intellectual discovery,” he wrote, “and the idea is to make that resonance work.”

Making that resonance work is one of the primary motivations behind the website you’re visiting right now.

As well as being the world’s largest hub of theoretical physics research and training, Perimeter Institute is, as part of its founding mandate, dedicated to sharing the joy and power of science with the world.

Created and curated by Perimeter’s team of writers, videographers, scientists, students, and generally creative types, this website is custom-made to make science accessible, engaging, and shareable to all.

Why? Because a scientifically engaged society is a successful society. And because science is awesome.

When you explore, you’ll find:

  • stories about leading-edge physics research from quantum information to condensed matter to cosmology
  • our award-winning Slice of PI monthly series, consisting of fun science facts designed for social media sharing
  • New and past issues of Inside the Perimeter magazine
  • a library of more than 300 science videos, including the renowned Perimeter Institute Public Lecture Series and other live webcasts
  • a responsive design that displays perfectly on a phone, tablet, laptop, or quantum communicator of the future
  • easy sharing to social media, including the ability to highlight any text on the site and instantly quote to Twitter

We hope you’ll jump in with the same exploratory spirit that drives scientific research discovery. To borrow another phrase from Sagan: “Somewhere, something incredible is waiting to be known.”

The world is facing some very big challenges, so the scientific mindset – and the optimism for a brighter future that fuels it – is more important than ever.

We hope this site will be your pathway to know some incredible things.


The International Summer School for Young Physicists is the ultimate summer camp for high schoolers with a passion for science. Though forced to go online-only by the pandemic, the program still succeeded in building connections which the campers say could last a lifetime.
