FlagComputer simulation of the measurement process

The measurement is a fundamental source of information w science and technology.

However the result given is never absolutely precise. Therefore, a proper and complete measurement must not only consist of the measured value, but also it must have a defined accuracy of the measurement.

This table can be used to illustrate the process of measurement. It is made from a board with horizontal rows of pins or nails, with a decreasing number of pins in each row in the upward direction.

In the real model, a ball is released by a special device, directly above the highest pin. The space between neighbouring pins is such, that the propability of the ball falling left or right is the same.
Here, it just appears from nowhere, and then it moves left or right, depending on a pseudo-random number. After going all the way down, the balls are accumulated in special compartments.

The measurement process: is the movement of the ball on the Table
Measurement errors: are the horizontal moves of the ball
Measurement result: is the number of the cell that the ball lands in
The exercise consists of two major parts:
  1. Qualitive description,
  2. Quantitive analysis.
