Science + AI: Discover what’s possible

Artificial intelligence is transforming the way scientists explore our world, from uncovering patterns in biological data to tackling global challenges in health and the environment.

At Waterloo, students in the Faculty of Science can learn how AI and science work together to drive new discoveries and innovation.

Examples of how we're using AI to make an impact

Common questions about the program

What's the difference between astronomy and astrophysics? Which of the two does the program focus on?

Astronomy is more about observational physics: what you can see and observe within an entity (including our vast universe). Astrophysics uses observational physics to propose new theories and tests them through mathematical modelling. Physics and Astronomy provides a good balance of both approaches.

What kind of things do you do in the astronomy labs? Do you use the observatory?

You'll use telescopes, star maps, and other instruments in your astronomy labs, and yes, one lab does use the observatory, which you can also use when it's open to the public.
