Quotes by Hero of Alexandria
By means of gears, levers, and weights, complex motions can be produced in automata.
The construction of automata requires a deep understanding of mechanics and pneumatics.
Automata can be used for entertainment, religious ceremonies, and even practical tasks.
The moving statues and figures demonstrate the ingenuity of human invention.
The water organ produces musical sounds by forcing air through pipes with water pressure.
The principle of the hydraulic press is that pressure applied to an enclosed fluid is transmitted undiminished to every portion of the fluid and the walls of the containing vessel.

The coin-operated machine demonstrates how a mechanism can be activated by the insertion of a coin.
The self-opening temple doors are an example of how pneumatic principles can be used for dramatic effect.
The measurement of areas and volumes is fundamental to all engineering endeavors.
To find the area of a triangle, multiply half the base by the height.
The volume of a pyramid is one-third the area of its base multiplied by its height.
By dividing complex shapes into simpler ones, their areas and volumes can be calculated.
The accurate measurement of physical quantities is the foundation of scientific inquiry.
The construction of a fountain requires an understanding of water pressure and flow.
The use of counterweights can balance forces and create equilibrium.
The principle of the pulley allows for the lifting of heavy objects with less effort.
The inclined plane reduces the force required to move an object vertically.
