Physics - which I'm interested in - has evolved in 4 major
phases:

- GALILEE : 16th and 17th century
162
Founders of physics : References

- NEWTON : 17th and 18th century
163
Founder of classical mechanics - the laws of universal
gravitation. The planets attract each other, the centre of
the Earth attracts objects to the Earth (gravitational force).

Special relativity (1905) and general relativity (1915).
Time became the 4th dimension.
The 3 usual dimensions (X, Y, Z): length, width, height,
constitute space. Over time, EINSTEIN also developed
the concept of space-time.
