🎉 2026 UAAA Annual Assessment Test: Mission Accomplished!

So proud of every student who participated in person at Diamond Bar Center and online! 💪

A special highlight: we celebrated our graduating seniors as they officially became UAAA Alumni Ambassadors! 🎓

Thank you to Dr. Ralph for inspiring our students to carry the spirit of mental math into their next chapters.

Huge thanks to our parents, volunteers, and teachers for making today such a success! 🙌

🧠✨ Mind-Blowing Pi Facts 🥧

Did you know 3.14 can look like “PIE” when you flip or mirror the numbers? That’s one reason we celebrate Pi Day with pie! 😄

📏 Infinite & Irrational
π has no repeating pattern and never ends. Mathematicians have calculated over 100 trillion digits… and they’re still counting!

🎂 Einstein’s Birthday
March 14 is also the birthday of Albert Einstein (born 1879). A perfect math-and-science coincidence!

🚀 NASA Only Needs 15 Digits
To send spacecraft across the solar system, NASA only needs 15 digits of π:
3.141592653589793

🌌 40 Digits = Universe Precision
With just 40 digits of π, you could measure the circumference of the visible universe with accuracy down to the width of a hydrogen atom!

📜 Ancient Approximations
• Egyptians (~1650 BC): 3.1605
• Archimedes (~250 BC): 3.1418 using 96-sided polygons
• Zu Chongzhi (480 AD): 3.1415926 — incredibly accurate for his time!

🎵 Musical Pi
Some people turn the digits of π into music, assigning each number a musical note!

🥧 The Pi Day Founder
Physicist Larry Shaw started Pi Day in 1988 at the Exploratorium in San Francisco by marching around a circle and eating pie. A delicious tradition!
