Happy Birthday, Noor Muhammad! May your day be filled with infinite joy—just like the endless dimensions of a C*-algebra. Your groundbreaking contributions to symmetric topology and pure mathematics have certainly multiplied our admiration exponentially. Who knew someone could make algebra look so effortlessly elegant?

From inspiring countless students at Moscow State University to penning insightful mathematical texts, you've proven that numbers can indeed tell fascinating stories. Here's hoping this year brings you even more success—and perhaps fewer equations that keep us awake at night!

Cheers to another orbit around the sun; may your happiness converge infinitely today!
