It was a telling moment: David Wallace-Wells, author of the new book The Uninhabitable Earth, was making an appearance on MSNBC's talk show Morning Joe. He took viewers through scientific projections for drowned cities, death by heat stroke and a massive, endless refugee crisis — due to climate change. As the interview closed, one of the show's hosts, Willie Geist, looked to Wallace-Wells and said, "Let's end on some hope."

It was just 10 years ago that I attended a lecture about Big Data and had my mind blown.

Using an understanding of social networks, along with the emerging tools of artificial intelligence and machine learning, I thought we were at the dawn of new age — allowing us to finally manage the complexity of human society for the well-being of all.

It hasn't turned out that way.

Now that we're well past the start of spring, you're probably inured already to all the green.

I mean, after those long months of winter, everyone's pumped about the first buds and shoots — so bright green and promising. But then, it's all ho-hum, leaves everywhere — whatever.

Well, not me, pal.

See, this spring I've been digging in on photosynthesis for some research I'm doing and, I gotta tell you, it's blowing my mind.

As I move through the stages of my life in science, I'm becoming all too aware of the weight of responsibility.

So, it's Election Day here in the United States.

Every presidential election seems important, but I am sure that I am not alone in thinking this one is different, maybe more important than most.

So, please, go vote.

When you're done, I give you (once again) Carl Sagan's beautiful "Pale Blue Dot" speech to put it all in perspective.

Revolutionary discoveries don't always breakthrough the hustle of daily life.

After all, when the Wright Brothers lifted their rickety plane off the sands of Kitty Hawk, the rest of the world was just out buying their eggs, milk and toilet paper. On that day who knew — or could imagine — that decades into the future millions of people would be sitting in giant jet-planes watching Direct TV and soaring five miles above the planet's surface.

ARI SHAPIRO, HOST:

In this fictitious world, all it takes is just a small vial of silvery fluid. Its illegal: very, very illegal. But if you can find it, just one vial is enough. Drink that down and soon the nano-scale molecular machines will work their way past the blood-brain barrier and begin coating the surfaces of your neurons.

So what makes America great?

Well, we can start off with poop: human poop, horse poop, all kinds of poop. In general we don't have a lot of poop on our streets — and that is a very good thing. How we got to this enlightened, poop-free state is, however, a story that might enlighten our own angry moment.

Does the size of space — those zillions of stars and zillions of miles of nothing between them — freak you out?

Well, if it does, guess what?

You're not alone.

I give a lot of public talks about the universe. Really. It's in my job description:

  • Astronomer. Check.
  • Study stuff in space. Check.
  • Give talks about universe. Check.

The combustion engine is dominant. In the United States, according to the latest estimates from the Census, more than 76 percent of us get to work alone in a car. The numbers are not quite as lopsided in some big cities, where public transit and other options are more widely available.

The New York Times recently carried a fascinating report on how a walk in nature can actually change the wiring in your brain. According to the story, not only did a brief walk in the woods make people report they felt happier but, using brain scans, researchers found time nature changed neurological functioning as well.

We don't make very good judges of distance, not on cosmic scales at least. Using our own wanderings on Earth as the judge of all things, evolution has left us poorly prepared for the epic scales of all things astronomical.

This week, as a box of electronics called New Horizons prepares to complete a nearly 10-year journey to Pluto, it's a good moment to reflect on just how far away even the objects in our astronomical backyard are from us.

Things are about to get really interesting in the long-stalled public discussion on climate change.
