similarity and congruence
Head First: Do you get a lot of pleasure out of
saving people so much work? It must be nice to be
liked.
Similarity: I do. It’s why I do what I do, really. I’m
a real stickler for recycling and conserving energy.
Head First: You mean like saving water?
Similarity: I mean like saving brain power! With
similarity, you can do a calculation once and then
reuse it over and over.
Head First: Oh, I see! Sorry…yes. So, what’s the
next step for you in your career?
Similarity: Well, really for me the next step is
increasing recognition. I need people to know that
I’m out here, waiting to get involved in saving them
time and energy.
Head First: Well, that’s certainly something we’d
love to help you with. Thanks for the quick interview.
Similarity Exposed
This week’s interview:
Similarity—faster or smarter—
which are you?
You sketch it—we’ll etch it!
Now that you’ve figured out all of those missing angles, you’ve
calculated everything that’s needed to etch the design.
Here’s my phone.
I can’t wait to see
how it turns out.
