Board describing or showing reality in four dimensions, a universal plotter and a scientific measurement and learning tool

A board or panel, characterized by comprising:

• a board (1);
• a T-shaped ruler (2), wherein the T-shaped ruler is defined by two portions, a horizontal portion and a vertical portion, the horizontal portion defining a horizontal axis or x-axis and the vertical portion defining a vertical axis or y-axis and;
• a first set of pulleys;
• a second set of pulleys;
• a third set of pulleys;
• a tool holder carriage (7);
• a pivot of rotation (11) on which the board rotates (11);
• wherein a first rail (3) is mounted on the board (1) and on which the horizontal portion of the T-shaped ruler (2) is positioned and wherein on the first rail (3) the horizontal portion of the T-shaped ruler (2) moves towards the horizontal axis or x-axis through the first set of pulleys on which a first cable pulls the T-shaped ruler (2);
• wherein the tool holder carriage (7) is positioned displaceably on a second rail, the second rail is defined by the vertical portion of the T-shaped ruler (2) towards the vertical axis or y-axis, and wherein the tool holder carriage (7) moves through the second set of pulleys on which a second cable pulls the T-shaped ruler (2);
• wherein a third rail is mounted on the tool holder carriage (7), the third rail assembled so as it defines an axis of depth or z-axis that is perpendicular to a plane formed by the horizontal axis or x-axis and the vertical axis or y-axis, and wherein on the third rail a tool stroke moves (9) through the third set of pulleys, this third set of pulleys is mounted on the tool holder carriage, which performs two movements in the vertical axis or y-axis and depth axis or z-axis, wherein the stroke tool traces a plane (Y, Z) perpendicular to the plane formed by the horizontal axis or x-axis and the vertical axis or y-axis.
