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.

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.
