Physics – branch of science that studies matter [9] and its motion through space and time, along with related concepts such as energy and force. [10] Physics is one of the "fundamental sciences" because the other natural sciences (like biology, geology etc.) deal with systems that seem to obey the laws of physics. According to physics, the ...

Whittaker's two volume A History of the Theories of Aether and Electricity subtitles volume one to The Classical Theories and volume two The Modern Theories (1900–1926).
In the case of a helium atom with two electrons in the 1s orbital, the Pauli Exclusion Principle requires that the two electrons differ in the value of one quantum number. Their values of n, l, and m l are the same. Accordingly they must differ in the value of m s, which can have the value of + 1 ⁄ 2 for one electron and − 1 ⁄ 2 for the ...
In the International System of Units (SI), the unit of time is the second (symbol: s). It has been defined since 1967 as "the duration of 9 192 631 770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom", and is an SI base unit.
