Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named after French mathematician, philosopher and physicist Blaise Pascal.
Pascal's principle is defined as: A change in pressure at any point in an enclosed incompressible fluid at rest is transmitted equally and undiminished to all points in all directions throughout the fluid, and the force due to the pressure acts at right angles to the enclosing walls.
Pascal contributed to several fields in physics, most notably the fields of fluid mechanics and pressure. In honour of his scientific contributions, the name Pascal has been given to the SI unit of pressure and Pascal's law (an important principle of hydrostatics).

The pascal, symbol Pa, is the SI coherent derived unit of pressure. It is the special name for the kilogram per metre per second squared, symbol kg m −1 s −2 . One pascal is defined as the pressure exerted by a perpendicular force of one newton on an area of one square metre .
This means stress is newtons per square meter, or N/m 2. However, stress has its own SI unit, called the pascal. 1 pascal (symbol Pa) is equal to 1 N/m 2. In Imperial units, stress is measured in pound-force per square inch, which is often shortened to "psi". The dimension of stress is the same as that of pressure .
