:38:00
- Have a nice day, dear?
- We had a swell time, didn't we?
:38:03
Yes.
:38:04
We went to the movies and had ice-cream
cones, and then we went to see Daddy.
:38:09
- I don't know how to thank you.
- I enjoyed every minute of it.
:38:13
We better get going, Mr. Carpenter.
:38:16
Aw, gee, you didn't finish your story.
:38:19
I'll finish it tomorrow. Good night, Bobby.
:38:22
- Good night.
- Good night.
:38:32
Come on, dear. Time to go to bed.
:38:36
Why did Mr. Carpenter
have to go with Mr. Brady?
:38:39
I don't know. Maybe it was a mistake.
:38:41
Oh.
:38:44
We sure had fun today. We saw the spaceship
and we went to see Professor Barnhardt.
:38:48
- Professor Barnhardt?
- Yeah, sure.
:38:50
- Mom, do I have to go to school tomorrow?
- Yes, of course, dear.
:38:55
Gee. I was hoping I could
go out with Mr. Carpenter again.
:39:06
Oh, come in. The professor's in his study.
:39:09
Thank you.
:39:19
This is the man you wanted to see, Professor.
:39:21
- Thank you, Captain.
- I'll wait outside.
:39:26
- You wrote this?
- It was a clumsy way to introduce myself.
:39:30
But I understand you're
a difficult man to see.
:39:33
- I thought you'd have the solution by now.
- Not yet. That's why I wanted to see you.
:39:38
All you have to do now is to substitute
this expression at this point.
:39:41
That will reproduce the first-order term.
But what about the effect of the other terms?
:39:46
Almost negligible. With variation
of parameters, this is the answer.
:39:50
How can you be so sure?
Have you tested this theory?
:39:54
I find it works well enough
to get me from one planet to another.
