The beginning of this week鈥檚 cover story by Eva Botkin-Kowacki and Charlie Wood might well be a Stieg Larsson thriller tilting over the rings of Saturn. Space exploration is not for the faint of heart, even if you鈥檙e just on Earth listening to the remote bleatings of a spacecraft traveling at 55,000 miles per hour 934 million miles away.聽

Yet for the scientists who devised the Cassini spacecraft鈥檚 slingshot path to Saturn, coiling its gravitational spring around Venus, and then hurtling toward the solar system鈥檚 most iconic outer planet, there was some solace. To them, this was not a feat of cosmic derring-do or a superhuman feat of engineering.聽

It was a math equation.聽

鈥淪cientists have come to realize that mathematics, when used with sufficient care, is a proven pathway to truth,鈥� writes physicist Brian Greene in 鈥淭he Fabric of the Cosmos.鈥澛�

Math has consistently opened vistas we never imagined, from quantum physics鈥� jittery micro-universe defined by uncertainty to the general theory of relativity proposed by Albert Einstein, where space and time are kneaded in seemingly unsettling ways.聽

But for the scientists of the Cassini mission, math has unrelentingly transformed Saturn from a curious jewel in the night sky into something we have vicariously touched and tasted. We have splatted down into the custard consistency of the surface of Saturn鈥檚 moon Titan, where liquid methane flows into frigid seas. We have caught the ice crystals of another moon, Enceladus, on Cassini鈥檚 mechanical tongue, tasting what could be the traces of organic life beneath its frozen surface. We have darted between Saturn鈥檚 rings like a dolphin amid the waves. And in Cassini鈥檚 final act, we will skim our fingertips though the clouds of the gas giant in a feat of scientific discovery that Renaissance astronomer Jean-Dominique Cassini could barely have envisioned.聽

At each step, as humanity鈥檚 capacity to reach outward and upward grew, math was waiting there to turn the most fantastical ideas into achieved reality.聽

So why is someone who was immensely relieved to get a C-plus in calculus rhapsodizing about mathematics?

Because it is impersonal. For scientists, this just comes with the job. If you get the math wrong, you can鈥檛 plead with Cassini to take the right trajectory to avoid becoming a gigantic fireball. Math is math.聽

That might seem like something that鈥檚 only relevant to science. But consider: What was Magna Carta鈥檚 quantum leap forward? It curtailed the power of the king through other political processes.聽

Seen another way, Magna Carta was a seminal step toward impersonalizing the exercise of power. American democracy was another step, further spreading power beyond any one person or group of people. The Founders sought to enshrine an ideal.

Science reveals many wonders. One is that principles, and not personalities or personal genius, are the safest foundation on which to progress. 聽
