# Space and Time

Published 2022-09-25

# Preamble

Henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.

- Hermann Minkowski (1864 - 1909)

This chapter has been prepared with Koh Zhi Yong and Gerald Kang Joon Kiat.

# Learning Objectives

By the end of this chapter, you will learn about concepts of space and time in the mathematical framework of special relativity. Through the eyes of two observers who are in constant motion relative to each other, you will uncover bizarre consequences such as a moving rod measuring a shorter length and a moving clock ticking slower.
