Let's make this birthday one to remember.

89 years old (Born on March 09, 1936)

Happy Birthday, Robert Barry! May your day be filled with invisible cakes, intangible balloons, and carrier-wave confetti that only you can truly appreciate. Your groundbreaking work—especially the legendary "Carrier Wave," where radio waves became art without transmitting information—has taught us all to see beauty in what we cannot see.

Here's wishing you another year of success in creating masterpieces out of thin air (literally!). Keep inspiring us by pushing boundaries beyond material limits. And remember: even if your birthday gifts seem nonexistent this year, it's probably just friends paying tribute to your artistic genius. Cheers to invisibility!
