Gather guiding questions to prompt participants to think

Here are a few:

• What's the right grid size when computing slopes?
• What does negative bendiness mean?
• If the bendiness is constant, what does that mean?
• If the bendiness is zero, what does that mean?

If we can convey 1 There are some circumstances where nature seems to make use of slope of slopes, and

2. that this can lead to the wave equation (that slope of slopes in time is the same as slope of slopes in space) then Andreas will be happy.

Space in space Space in time

The "bad news" is that you have to wrap your head around both the space and time concepts.

What is our timeline to be in the classroom? Do a lesson, first week of April.

We don't need the machinery of limits, we just need to take differences and divide.
