The tools we have access to to capture a snapshot of the world – whether a mobile phone, access to a news stream or an x-ray. The time between snapshots. And the ability to call on other data sources to retrospectively fill in the gaps once the second snapshot is known e.g. if the x-ray highlights early stage lung cancer and you are able to correlate this to the air pollution levels of the places you’ve traveled (for work, hello), that you commute to work by bicycle along routes that are heavily trafficked, the bars you’ve hung out in and the smoking behaviours of your social group.
