Signs

At the Discovery Museum in Acton, MA, today:

How Learning Occurs: "Building a robot that works involves building a robot that doesn't work and then figuring out what is wrong with it." (Benjamin Erwin)

[As I like to do, I googled to find out who Erwin is. He has something to do with LEGO!]

On the road on the way there and back:

Thickly settled.

Hidden driveway.

Whistles not blown. [Before a train crossing.]

Not a sign, but what Andrea said as we were trying to get the kids organized to leave the museum:

"We never get anywhere, and when we are somewhere, we never get back from there."
