History of PhysicsAt present it seems that only physics can provide satisfactory answers to eternal philosophical question such as the origin of consciousness and the destiny of humanity as the apparent sole carrier of consciousness. Thus, history of physics represents the history of consciousness. III-II MILLENNIUM AD
***Creation of solar and water clocks.
Discovery of techniques for measuring weights and dimensions of objects. A weighing scale is invented.
The balance is the first invented mass measuring instrument. It is made of a pivoted horizontal lever of equal length arms, called the beam, with a weighing pan, also called scale (hence the term "scale" or "scales"), suspended from each arm.
***Ancient Egyptian as early as 2750 BC described electric fish and referred to these fish as the "Thunderer of the Nile", thus suggesting a common nature of these electric phenomena.
VI CENTURY AD
***First observations in acoustics. Pythagoras discovers a relation between the consonance and the length of the tube or a string. Pythagoras wanted to understand why some intervals seemed more harmonious than others. He found answers in terms of numerical ratios representing the harmonic overtone series on a string.
***First observation on electricity and magnetism. It is understood that amber rubbed with fur attract small objects. Thales of Miletos stated that such rubbing gives magnetic properties to amber, while minerals such as magnetite were magnetic without rubbing. Thus a link between electrical and magnetic phenomena is anticipated.
V-IV CENTURY AD
An idea about a discrete nature of matter appears...
