YEN-JIE LEE: So to make the demo done coherently
with your lecture, a lot of preparation
is actually needed in advance.
So first of all, you need to make
a list of the demo which you would like
to include in your lecture.
And secondly, you need to work with our technical instructors
to set up those demos so that they work nicely
during the class.
Usually, I come to the class, like,
half hour to one hour before the lecture
to make sure that everything is working as I expect.
And also there were a lot of communication
between me and my technical instructors
to tune the parameters to what we would
like to demo during the class, and to make sure
that the physical phenomena can be seen clearly
from the demo of our choice.
And finally, you need to decide when
do you want to do those demos.
And what you are going to get is that, OK,
omega, omega D around omega 0, then
you are going to get large type amplitude.
OK?
So now, what I am going to do is to continue--
As I mentioned before, I usually like
to include the demo after the calculation is done.
Sometimes maybe it's a good idea to use the demo
as a teaser for the calculation and see that, OK,
we can reproduce this result by physics intuition
and mathematical calculation.
So that's actually the kind of consideration
when I choose which kind of demo to be included
in the lecture and the kind of preparation before the class,
and finally, the timing, which I decide
where to insert those either experiments
or analytical calculation using program during my lecture.
