Things that we will not mention but students are assumed to know:
1. square of a binomial:
(a + b)2 = a2 + 2ab + b2
2. difference of squares:
(a + b)(a b) = a2 b2

SPECIAL RELATIVITY
Albert EINSTEIN introduced his SPECIAL THEORY OF RELATIVITY in 1905. To
understand the theory, we will first review the background, the theoretical and
experimental developments since Newton.
SPECIAL means just, not general. The theory
