"Curiosity" was launched by NASA in 2011 to study the surface of Mars. The car-sized robot still roams over the planet's surface in 2020, still energized by its solar battery, still sending information back to earth.

Was something like Curiosity foreseen or anticipated even a hundred years ago, back in 1920? It's now a cliche, but technology exploded over the last century, technology that would have looked like magic not so long ago: technology that taught us the structure of our DNA and the structure of the universe.

Of all the discoveries made in the course of mankind’s long march to civilization, there was one primal discovery that made . . all this possible. It’s a discovery we use every day and take completely for granted. But this discovery changed everything. 

Humankind discovered how to make and tame fire.
