Example: Spontaneous Decay Simulation

a warning sign for radiation

Spontaneous Decay Simulation

Basic, phenomenological fact of decay

$Delta N = \lambda \Delta t$
Basic algorithm

if $Delta N = \lambda \Delta t$ , nucleus decays, Nnuc=Nnuc-1; else it remains (decay.c,) .f

log N versus t

The Virtual Web Geiger Counter

Increases belief in simulation, explanation of nature
Converts N vs t to 1's and 0's
Opens sound player : sound of simulation (.au, 8K): (turn on volume, stupid).
Hear decay change from exponential to stochastic as fewer N
Sample Web Geiger counter (CGI-bin script over Web)
Number of atoms (0..500):
Decay constant (0..1):
Data Format: .au, Sampling Rate: 8kHz, Size: 80K
