Question

What is the similarities and difference between Lamport’s Logical clock and vector logical clock ?

Answer 1

Physics¶

The understanding of time has evolved greatly in the past 150 years.

With Einstein’s Special and General Relativity Theories, we’ve come to understand:

That time is interwoven with space

Time is relative to the reference frame of an observer

We now know that simultaneity is a relative concept. Two events A and B occurring simultaneously in one reference frame may appear to be ordered A then B in another frame and B then A in yet another reference frame.

All of this is true without invalidating the observations our causal relationships observed in any reference frame.
