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.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): How many contradictory facts does the problem of the direction of time arise from?
Ah, so.. two

In 885 AD the Armenians reestablished themselves as a sovereign kingdom under the leadership of Ashot I of the Bagratid Dynasty. A considerable portion of the Armenian nobility and peasantry fled the Byzantine occupation of Bagratid Armenia in 1045, and the subsequent invasion of the region by Seljuk Turks in 1064. They settled in large numbers in Cilicia, an Anatolian region where Armenians were already established as a minority since Roman times. In 1080, they founded an independent Armenian Principality then Kingdom of Cilicia, which became the focus of Armenian nationalism. The Armenians developed close social, cultural, military, and religious ties with nearby Crusader States, but eventually succumbed to Mamluk invasions. In the next few centuries, Djenghis Khan, Timurids, and the tribal Turkic federations of the Ak Koyunlu and the Kara Koyunlu ruled over the Armenians.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What group fled the invasion of the Mamluk in 885 AD?
Ah, so.. unanswerable

The broad field of animal communication encompasses most of the issues in ethology. Animal communication can be defined as any behavior of one animal that affects the current or future behavior of another animal. The study of animal communication, called zoo semiotics (distinguishable from anthroposemiotics, the study of human communication) has played an important part in the development of ethology, sociobiology, and the study of animal cognition. Animal communication, and indeed the understanding of the animal world in general, is a rapidly growing field, and even in the 21st century so far, a great share of prior understanding related to diverse fields such as personal symbolic name use, animal emotions, animal culture and learning, and even sexual conduct, long thought to be well understood, has been revolutionized. A special field of animal communication has been investigated in more detail such as vibrational communication.
If it is possible to answer this question, answer it for me (else, reply "unanswerable"): What is the study of human communication called?
Ah, so..
anthroposemiotics
