A long time ago, when I was working on my Ph.D. research, I learned to use supercomputers to track the complex 3-D motions of gas blown into space by dying stars.

Using big computers in this way was still new to lots of researchers in my field and I was often asked, "How do you know your models are right?"

Over the past few months, the Amazon drama-comedy The Marvelous Mrs. Maisel has been the show everyone loves to talk about.

Science is not a philosophy or a spiritual path; it's a way of behaving in the world.

But since tribalism and polarization have made "alternative facts" a reality of public life, there is something we can learn from science to help us navigate the troubled waters and find a more resilient civic life.

The lesson begins with understanding the right relationship not to knowing but to not knowing. To be blunt, if we want to fight ignorance, we must start with our own.

Science can just knock me to the floor.

Sometimes it's the revelation of some previously unseen phenomena. Other times, it's a new way to see something you thought you already understood. Then there are the times when connections pop up between things you never imagined to be connected.

And sometimes, it's all of them at once.

Ebenezer Scrooge was famously visited by three ghosts in A Christmas Carol. The past, present and future all converged on poor Scrooge in an effort to save him from his own narrow vision of the world and wake him to the wonders of the life right before his eyes.

Half a billion years. That's how long the Earth existed as a barren world.

Half a billion years of hell before the planet's molten seas of liquid rock cooled to give the world a solid surface.

Only then did life appear. Only then did our world's fantastic history of microbes evolving to mollusks, evolving to dinosaurs, evolving to us, begin.

But what, exactly, was that beginning?

In an era of "fake news" and "alternative facts," we now face a massive disconnect between what science thinks it understands about the world (i.e., global warming) and what some people want to believe is true.

But how does "science" come to know anything about anything? After all, what is science but a collection of people who call themselves scientists? So isn't it as flawed as everything else people create?

As the tax bill moves through Congress, an issue has risen that hits dangerously close to U.S. efforts in science.

Just before Thanksgiving, the Internet lit up with the remarkable video of Boston Dynamics' robot Atlas doing a backflip.

In the Spring of 2009, the H1N1/09 virus — dubbed "swine flu" — made the jump from pigs to people and began claiming its first victims.

Fearing the beginning of a global swine flu pandemic, terrified health officials began planning for the worst. Shutting down the world's major airports became the nuclear option of their arsenal — the last hope for halting the virus from reaching unstoppable thresholds of contagion.
