What Time Really Is

Modern physics treats time as part of spacetime: measured durations can differ with relative motion and gravity. Thermodynamics adds an arrow associated with irreversible macroscopic…

What Entropy Really Is

Thermodynamic entropy is a state quantity associated with macroscopic processes; statistical mechanics connects it to the multiplicity of microscopic arrangements compatible with a macrostate. The familiar word disorder…

There Is Time Between Rainfall and a River's Response

Rain today does not imply that a river will change in the same way today. Where the rain fell, what happened in the soil, which path the water followed, and how long that path took all contribute to the river's response.

When Clocks Drift, the Order of Events Can Drift Too

When logs from several servers are compared side by side, timestamps are often used to reconstruct the incident. If the clocks differ, however, a later event can appear to have happened first. Sorting timestamps is not enough to prove causal order.

How We Learned to See Time

Newtonian absolute time provided a successful framework until relativity replaced it with a spacetime in which simultaneity depends on the observer's state of…

An RTP Timestamp Is Not Wall-Clock Time

A timestamp inside a packet can look like a clock reading, but RTP timestamps primarily describe position in the media clock. Wall-clock time, media time, and packet arrival time are different concepts.

A Counter Reset Changes the Story in the Graph

A counter accumulates events over time, but some counters start over when a process restarts. Subtracting the next value from the previous one can then produce an impossible negative event. The events did not run backward; the measurement history was reset.

Listening to a Song About Time Also Costs Time

An essay about time can be skimmed quickly, but a song unfolds at its own pace. When I think about Pink Floyd's Time, that relationship matters: understanding the subject also requires the listener to remain inside time.
