WebEinstein’s Second Postulate. The second postulate upon which Einstein based his theory of special relativity deals with the speed of light. Late in the 19th century, the major tenets of classical physics were well established. Two of the most important were the laws of electricity and magnetism and Newton’s laws.

Main Postulates of Werner

WebPostulates of Werner’s theory: a. Two types of valencies are shown by most metallic elements: Primary valence or principal valence. Secondary valence. b. The tendency of every metal is to satisfy both primary and secondary valences. c. The number of secondary valence shown by each metal is fixed. WebThese four postulates establish the field of the data and show it to be a mixture of law and chaos, with levels of analysis of the mixture. The three ontological postulates of the science are as follows: (5) Operation on a field is possible with instruments. (6) The discovery of laws is a process. (7) There is progress toward more inclusive theory. divisional public school lahore model town
