Time in Physics
“Time in physics is defined by its measurement: time is what a clock reads. It is a scalar quantity and, like length, mass, and charge, is usually described as a fundamental quantity. Time can be combined mathematically with other physical quantities to derive other concepts such as motion, kinetic energy and time-dependent fields. Timekeeping is a complex of technological and scientific issues, and part of the foundation of recordkeeping.”

Suggested Questions
- 예술가의 음악, 미술 작품 속에 표현된 시간의 개념과 과학적 시간의 개념은 얼마나 다른 것일까?
- 시간의 시작점은 존재하는 것일까? 강의에서 언급된 논점을 비판적으로 생각해 본다면?
- 휘어진 공간과 느리게 가는 시간은 우리의 ’직관’과 어떤 면에서 배치되는가?
- ‘빛으로 가는 시계’ 보다 더 “좋은” 시계를 찾을 수 있을까? 다른 종류의 시계의 장단점을 논의해 보자.
