Today, TikTok is celebrating the magic of math and marking the two-year anniversary of our STEM feed. From favorite teachers inspiring students beyond the classroom to communities exploring the wonders of the world together, our STEM feed connects users with engineers, scientists, astronomers, and more. It’s a space where curiosity thrives and learning has no limits, bringing together diverse creators and experts to share discoveries, insights, and a passion for STEM—making science, technology, engineering, and math more accessible and engaging for everyone.

As part of our Pi Day celebrations on March 13, (3.14), we’re showcasing creative ways to incorporate STEM and learning into family activities. Honoring π (Pi), the never-ending mathematical number that helps measure circles, we’re highlighting how it appears in everyday life through hands-on DIY projects, baking delicious recipes inspired by its digits, and more—turning Pi Day into an interactive and memorable experience for all ages.
