SimuLab 11: Building an Aggregate by Computer

Can the aggregate building process be made faster? Of course! Let the computer make random choices and move the walker. The computer moves the walker much faster than we can, but uses the same simple process.

Open the Aggregation Kit program (see Java Applet Page. On the right is a black screen with a so-called "seed'' molecule in the center.

Q4.14: Why is the DLA pattern so "leggy,'' so "spidery?'' Why isn't it a compact blob? In your answer, think of the growth process in detail: the walker staggering back and forth as it passes inward between the ends of two legs.
