Mathematics Goes to the Movies

by Burkard Polster and Marty Ross

**Alien Hunter (2003)**

6:00

The hero (Julian Rome) is giving a lecture. In the background we see a blackboard
with maths.

8:28

JULIAN: Look at this.

SAM (his assistant, or colleague): What have you got?

JULIAN: Look at that. (pointing at a signal on a screen)

SAM: Nonrandom?

JULIAN: Definitely. Fixed length pulse groups, discriminate text consisting
of prime numbers, repeated over and over.9:08

DR JOHN BECKMAN (his boss): You said it was non-random?

JULIAN: Yes, with a fixed pulse device.

DR JOHN BECKMAN: You mean some sort of new search signal?

JULIAN: It’s possible. But search text is always diverse samples with
mathematical data. This has no parallel plain text.30:30

KATE BRECHER: What are you going to do?

JULIAN: Try and find out what’s buried in the harmonic(s?).

KATE: How?

JULIAN: Mathematics.

Screens full of 1s and 0s.

33:44

JULIAN: It’s a black box. At first I thought it was a location bounce
for celestial navigation, but it’s a little bit simplistic. Then Grisham
mentioned it seemed like a beacon, and that’s when it hit me. This came
here by mistake, and the signal’s meant for whoever lost it…. There
is something else. The primary signal itself is a cryptographic key that unlocks
the message buried in the harmonics. So I compared the cipher texts against
itself and the coincidences between the character strings. A deviation arises
from strings of intervals divisible by five bit repeats at shifts of 70 and
125.

Some more computer screens (nothing interesting)

34:46

NYLA: Could there be more to the message that’s not being deciphered?

JULIAN: Sure, there could be more than one crypyographic key, shift intervals
can change, strings vary. The possibilities are endless.

41:20

JULIAN: Since time and space is a constant any intelligence within that environment
will define it the same.

NYLA: But with a different language?

JULIAN: Yeah. I mean mathematics is the basic expression of any language. So
you just have to find a way to solve the equations. That’s what it’s
doing, with the help of the cryptographic key from the signal.

NYLA: It’s kind of like Mind Maze

JULIAN: Like what?

NYLA : It’s a computer game where you have to figure out the math puzzles.
Each time you do, you get a key that unlocks the door to another world.

1:06:10

SHELLY: It still could be hidden in the protein.

KATE: You know how unlikely that is.

JULIAN: How unlikely? What are the odds?

SHELLY: 99.999 to the infinite.

JULIAN: But not a 100.
