Dear Skywatchers,

It sure looks like the sun moves across the sky. And if you have spent a lifetime seeing the sun move across the sky and believing the earth is the center of everything, it would be pretty hard to change your mind.

Of course, we know better now. But it took many hundreds of years for everyone to convince themselves. But changing our minds teaches us a powerful lesson: what else is not the way it seems?

As scientists, we have to join our observations of the world with our knowledge of how systems work. Only then can we get the true picture of what’s going on. And it might not be what it seems.

Sincerely,

Mr. Heimbuck
