Lecture 8 Units and Measurement

Example 2.6 Two clocks are being tested against a standard clock located in a national laboratory. At 12:00:00 noon by the standard clock, the readings of the two clocks are :

Tuesday
Wednesday
Thursday
Friday
Saturday
Sunday
Clock 1
12:00:05
12:01:15
11:59:08
12:01:50
11:59:15
12:01:30
12:01:19
Clock 2
10:15:06
10:14:59
10:15:18
10:15:07
10:14:53
10:15:24
10:15:11

If you are doing an experiment that requires precision time interval measurements, which of the two clocks will you prefer ?
