The problem of the direction of time arises directly from two contradictory facts. Firstly, the fundamental physical laws are time-reversal invariant; if a cinematographic film were taken of any process describable by means of the aforementioned laws and then played backwards, it would still portray a physically possible process. Secondly, our experience of time, at the macroscopic level, is not time-reversal invariant. Glasses can fall and break, but shards of glass cannot reassemble and fly up onto tables. We have memories of the past, and none of the future. We feel we can't change the past but can influence the future.
What do we not have memories of?
A: the future

At the time of the Berlin Conference, Africa contained one-fifth of the world’s population living in one-quarter of the world’s land area. However, from Europe's perspective, they were dividing an unknown continent. European countries established a few coastal colonies in Africa by the mid-nineteenth century, which included Cape Colony (Great Britain), Angola (Portugal), and Algeria (France), but until the late nineteenth century Europe largely traded with free African states without feeling the need for territorial possession. Until the 1880s most of Africa remained unchartered, with western maps from the period generally showing blank spaces for the continent’s interior.
Europe did not feel the need to posses territory in Africa until?
A: 1880s

On the field at the beginning of a play are two teams of 12 (unlike 11 in American football). The team in possession of the ball is the offence and the team defending is referred to as the defence. Play begins with a backwards pass through the legs (the snap) by a member of the offensive team, to another member of the offensive team. This is usually the quarterback or punter, but a "direct snap" to a running back is also not uncommon. If the quarterback or punter receives the ball, he may then do any of the following:
