Query: Impact of memory on human dynamics   Our experience of web access slowing down is a consequence of the aggregated
web access pattern of web users. This is just one example among several human
oriented services which are strongly affected by human activity patterns.
Recent empirical evidence is indicating that human activity patterns are
characterized by power law distributions of inter-event times, where large
fluctuations rather than regularity is the common case. I show that this
temporal heterogeneity can be explained by two mechanisms: (i) humans have some
perception of their past activity rate and (ii) based on that they react by
accelerating or reducing their activity rate. Using these two mechanisms I
explain the inter-event time statistics of Darwin's and Einstein's
correspondence and the email activity within an university environment.
Moreover, they are typical examples of the the accelerating and reducing class,
respectively. These results are relevant to the system design of human oriented
services.
