Let's make this birthday one to remember.

72 years old (Born on February 20, 1953)

Happy Birthday, Jon! Your brilliance in computer science truly transcends dimensions—we're certain your k-dimensional cake today will be spatially partitioned into optimal slices. Thanks to you, data points everywhere finally found their rightful place; who knew organizing our mess could be so elegantly efficient?

Time marches on, yet your invention—the incredible k-d tree—continues to inspire innovations across fields from databases and robotics, to graphics and AI. Today we celebrate not just another year passed—or dimension added—but the countless moments of clarity you've given us.

Cheers to you—a timeless genius whose cleverness remains wonderfully undiminished by dimensionality constraints!
