Mole Day and Celebrating Science

Celebrating Science Geekdom and Nearly Two Decades at Caltech

Caltech Mole Day Celebration

October 23rd—10/23—is Mole Day, that wonderfully nerdy holiday celebrating Avogadro's number: 6.022 × 10²³, a cornerstone of chemistry that lets us count particles by the mole, and a perfect excuse for science geeks to throw themed parties, bake atom-shaped cookies, or just revel in atomic enthusiasm. For most people, it's just another Tuesday in late October. But for chemistry enthusiasts and science geeks everywhere, it's a day to embrace the beautiful precision of the molecular world. And after 16 years at the California Institute of Technology, I can honestly say there's no better place to celebrate your inner science nerd than on a campus where casual elevator conversations about quantum mechanics are completely normal. Especially in a year shaped by isolation and uncertainty, that shared love of science felt more grounding—and more necessary—than ever.

Where Being a Science Geek Actually Pays Off

At Caltech, intellectual curiosity isn't just tolerated—it's the currency of daily life. You might find yourself in an elevator with someone casually discussing their latest paper on gravitational waves, or overhearing a lunch conversation about the finer points of Mars geology. It's the kind of environment where Mole Day isn't just acknowledged with a passing nod; it's genuinely celebrated by people who get excited about things like molecular constants and stoichiometric calculations.

JPL's Mission Control facility

One of the unexpected perks of working at Caltech was the connection to NASA's Jet Propulsion Laboratory. Since Caltech manages JPL, I had incredible opportunities to visit the Lab and indulge the space science geek that's been hiding inside me since childhood. Walking through JPL's halls, seeing actual mission control rooms where engineers communicate with spacecraft millions of miles away, witnessing the hardware that would eventually travel to Mars or Saturn—it was like stepping into the future I'd dreamed about as a kid watching Star Trek.

These weren't just guided tours for VIP visitors. They were genuine glimpses into humanity's greatest adventures, tangible reminders that the theoretical physics discussed in Caltech classrooms eventually becomes the technology that explores our solar system. Standing in those rooms, I couldn't help but think about all the science fiction I'd consumed over the years and realize: this is how we actually get there.

Some of my favorite experiences were bringing my children to share in the wonder of these scientific environments. During "Take Your Daughters to Work Day" at Caltech, Faith and Kailey got to visit actual research labs and help scientists make ice cream with liquid nitrogen—pure magic for kids who thought science was just textbooks and homework. But perhaps even more memorable was bringing my son Teddy to JPL's open house, where we saw Mars landers being constructed and talked to scientists who were actively searching for exoplanets. Watching his eyes light up as researchers explained how they detect worlds orbiting distant stars reminded me why I fell in love with science in the first place. There's something special about sharing your workplace with your children when that workplace happens to be connected to missions exploring the solar system and pushing the boundaries of human knowledge. Even if they didn't all end up pursuing STEM careers, those visits planted seeds of curiosity and showed them that science isn't just theory—it's adventure, discovery, and the relentless pursuit of answers to the biggest questions we can imagine.

When Hollywood Comes to Campus

During my time at Caltech, the campus became something of a magnet for Hollywood productions. It seemed like there was always a film crew somewhere, drawn by our authentic scientific atmosphere and those iconic academic buildings that just scream, "serious research happens here."

I got to witness some of the filming for both Numb3rs and Young Sheldon—shows that, in their own ways, tried to bring scientific thinking to mainstream television. Watching the Young Sheldon crew work was particularly fascinating, knowing that the show's series finale would bring young Sheldon Cooper to Caltech as a graduate student. The attention to detail was remarkable—those whiteboards covered in equations weren't just random scribbles but real physics, carefully vetted by actual Caltech physicists. It was Hollywood magic meeting scientific rigor, and seeing that process unfold was absolutely captivating.

Numb3rs brought a different energy to campus, showcasing how mathematical thinking could solve real-world problems. As someone immersed in the Caltech environment, it was thrilling to see mathematics portrayed as the exciting, dynamic field it really is, rather than the dry subject many people remember from high school algebra.

I even had my own brief brush with science television when I was selected for a "man on the street" interview for a cable science show. The irony? Because I could actually explain gravitational waves coherently, they didn't use my footage. Apparently, they were looking for one of those "gotcha" moments where random people fumble through complex scientific concepts. Still, I got to be part of the process and witness how science communication works from behind the scenes—a reminder that sometimes being scientifically literate works against you in the entertainment world.

Meeting My Science Heroes

But perhaps the most humbling aspect of my Caltech experience was the opportunity to meet and work alongside scientific legends. These encounters went far beyond what any science geek could reasonably hope for.

Having actual working meetings with luminaries like Kip Thorne—the theoretical physicist whose work on gravitational waves eventually earned him the Nobel Prize—was both intimidating and exhilarating. Here was someone whose research literally opened a new way of observing the universe, and I'm sitting in his office discussing fundraising strategy with him.

Voyager's Golden Record

One of my most personally meaningful encounters was getting to work with Ed Stone, a Caltech faculty member, former JPL director, and mission scientist for the Voyager project. As a kid, I was absolutely enthralled by the Voyager flybys of the outer planets—those stunning images of Jupiter's Great Red Spot, Saturn's rings, and the mysterious moons of the gas giants. They sparked my lifelong fascination with space science. Meeting Dr. Stone was like meeting one of my childhood heroes. In my work, I had the privilege of helping establish a scholarship that bears his name, and he came to my office several times during that process. Here was the man whose vision and leadership had given us those incredible cosmic postcards that inspired an entire generation of science nerds.

I also had the remarkable opportunity to meet Gordon Moore, the Caltech alum who co-founded Intel and whose famous "Moore's Law" predicted the exponential growth of computing power. Dr. Moore was always thoughtful and genuine in our interactions—mostly revolving around his annual philanthropic gifts to the Institute—and I was tickled that he remembered my name from year to year. One moment I'll never forget: holding a one-million-share Intel stock certificate in my hands while helping facilitate some of his philanthropy. The weight of that piece of paper—representing not just enormous financial value, but the legacy of innovation that built the modern computer age—was absolutely surreal.

These weren't just brief handshakes at formal events. These were real conversations, working meetings, moments where you could pick the brain of someone who had literally reshaped our understanding of the universe or revolutionized entire industries. Each brought their own infectious passion—Kip Thorne's enthusiasm for the theoretical beauty of physics, Ed Stone's wonder at cosmic exploration, Gordon Moore's vision for technological progress. Their ability to make the most complex concepts feel accessible and exciting reminded me why I fell in love with science in the first place.

The Real Magic of Scientific Thinking

As we celebrate Mole Day, I'm reminded that the best part of being surrounded by scientific thinking isn't just the knowledge itself—it's the mindset. It's the curiosity that drives you to ask "what if?" and "why?" It's the collaborative spirit that brings together brilliant minds from different disciplines. It's the willingness to get genuinely excited about something as wonderfully specific as a number that helps us understand the fundamental building blocks of matter.

Caltech's Millikan Library (and my office)

That mindset felt especially vital in 2020. As I walked back to my office after a routine COVID-19 screening test, I was struck by how quiet and empty the Caltech campus had become. The vibrant intellectual buzz—the impromptu hallway debates about quantum mechanics, the packed lecture halls, the bustling labs—had been replaced by a pandemic-induced stillness. But even in the silence, science was at the center of our lives. It was science that helped us understand the virus, science that guided public health responses, and science that ultimately delivered the vaccines.

Reflecting on my experiences at Caltech—from holding Gordon Moore's Intel stock certificate to walking through JPL's mission control rooms, from meeting the visionary behind Voyager to watching Hollywood try to capture scientific authenticity—I'm struck by a common thread: science isn't just about understanding the world; it's about transforming it.

Ed Stone's Voyager missions didn't just teach us about Jupiter's moons; they fundamentally changed how humanity sees itself in the cosmos. Gordon Moore's insights didn't just predict technological growth; they enabled the digital revolution. Kip Thorne's gravitational wave research didn't just confirm Einstein's theories; it opened an entirely new window for observing the universe.

And in the face of a global pandemic, science once again proved its power—not just through discovery, but through real-world action that saved lives.

The study of science matters because it's how we push beyond the boundaries of what we think is possible. Every equation on those Hollywood whiteboards, every conversation in a Caltech hallway, every moment spent geeking out over Avogadro's number—these aren't just intellectual exercises. They're the building blocks of innovation, the foundation of progress, and the source of solutions to challenges we haven't even imagined yet.

Whether you're calculating moles in a chemistry lab, pondering the mathematics behind gravitational waves, or simply marveling at the elegant patterns in nature, you're participating in humanity's greatest ongoing adventure: understanding our universe and our place in it.

So here's to Mole Day, to Avogadro's number, and to all the science nerds out there who understand that some of the most beautiful truths in the universe can be expressed in equations, constants, and the simple joy of discovery. After 16 years surrounded by people who dedicate their lives to pushing the frontiers of knowledge—and during a year when science helped us confront a once-in-a-century crisis—I’ve learned this: the world needs more people who will unapologetically geek out over the profound mysteries that make life—and the universe—so astonishingly beautiful.

Happy Mole Day, everyone! May your calculations be accurate, your vaccines effective, and your sense of wonder never fade.
