“The roe deer attains a maximum life span (in the wild) of ten years. When alarmed, it will bark a sound much like a dog and flash out its white rump patch. Rump patches differ between the sexes, with the white rump patches heart-shaped on females and kidney-shaped on males. Males may also bark or make a low grunting noise. Females (does)make a high pitched "pheep" whine to attract males during the rut (breeding season)in July and August. Initially it is the female who goes looking for a mate and it is common for her to lure the buck back into her territory before mating. The roe deer is territorial, and whilst the territories of a male and a female might overlap, other roe deer of the same sex are excluded unless they are the doe's offspring of that year.“

“Scholars have observed analogues to the phoenix in a variety of cultures. These analogues include the Arabic anqa (named after its prominent white neck), the Hindu garuda and gandaberunda, the Russian firebird, the Persian Simorgh, the Turkish Zümrüdü Anka, the Tibetan Me byi karmo, the Chinese fenghuang, and the Japanese hō-ō.“

“If the strip is cut along about a third of the way in from the edge, it creates two strips: One is a thinner Möbius strip — it is the center third of the original strip, comprising 1/3 of the width and the same length as the original strip. The other is a longer but thin strip with two full twists in it — this is a neighborhood of the edge of the original strip, and it comprises 1/3 of the width and twice the length of the original strip.
Other analogous strips can be obtained by similarly joining strips with two or more half-twists in them instead of one. For example, a strip with three half-twists, when divided lengthwise, becomes a strip tied in a trefoil knot. (If this knot is unravelled, the strip is made with eight half-twists in addition to an overhand knot.) A strip with N half-twists, when bisected, becomes a strip with N + 1 full twists. Giving it extra twists and reconnecting the ends produces figures called paradromic rings.
A strip with an odd-number of half-twists, such as the Möbius strip, will have only one surface and one boundary. A strip twisted an even number of times will have two surfaces and two boundaries.“

“Orion (griechisch Ὠρίων) ist ein riesenhafter, unter die Sterne versetzter Jäger der griechischen Mythologie. Als riesiger und starker Jäger lebte er in Böotien und Kreta. Bei der Jagd wurde er von seinen Jagdhunden Sirius und Procyon begleitet, die auch am Himmel sein Sternbild (s. u.) umgeben. Seine Herkunft ist widersprüchlich: manchmal ist er der Sohn von Poseidon und der Euryale (nicht zu verwechseln mit der Gorgone Euryale), manchmal hat er gleich drei Väter, nämlich Poseidon, Zeus und einen Dritten (Hermes oder Ares). Alle drei mischten ihren Samen in einem Beutel aus Stierhaut. Von Zeus hat er daher seine Begeisterung für erotische Abenteuer, und Poseidon vererbte ihm die Fähigkeit, über Wasser zu gehen.
Seine Gattin Side wurde von Hera in den Tartaros hinab gestoßen, da sie sich zu sehr ihrer Schönheit rühmte. Nach der Sage um Oinopion, einen Sohn des „Weingottes“ Dionysos, verliebte sich dessen Tochter Merope in Orion, aber Oinopion stimmte der Vermählung nicht zu. Vor Wut vergewaltigte Orion sie, wofür ihm ihr Vater die Augen ausstach, nachdem er ihn mit Wein betrunken gemacht hatte. Hephaistos ermöglichte es Eos, der Göttin der Morgenröte, Orions Sehkraft wiederherzustellen, indem er ihm den Schmied Cedalion schickte, um ihn zum Sonnenaufgang zu führen. Orion schwor, Rache an Oinopion zu nehmen, aber Hephaistos half Oinopion und versteckte ihn unterirdisch, so dass Orion ihn nicht finden konnte. Stattdessen ließ er sich Eos zuliebe auf der Insel Delos nieder. Eos verliebte sich in ihn, worauf er aus Eifersucht von Artemis mit Pfeilen getötet wird. Später versetzt Artemis den Jäger Orion aus Reue als Sternbild an den Himmel, wo er noch heute den schönen Plejaden nachstellt – die Plejaden gehen als Siebengestirn kurz vor Orion auf und unter.“

“Randomness, as opposed to unpredictability, is an objective property. Determinists believe it is an objective fact that randomness does not in fact exist. Also, what appears random to one observer may not appear random to another. Consider two observers of a sequence of bits, when only one of whom has the cryptographic key needed to turn the sequence of bits into a readable message. For that observer the message is not random, but it is unpredictable for the other.
One of the intriguing aspects of random processes is that it is hard to know whether a process is truly random. An observer may suspect that there is some "key" that unlocks the message. This is one of the foundations of superstition, but also a motivation for discovery in science and mathematics.
Under the cosmological hypothesis of determinism, there is no randomness in the universe, only unpredictability, since there is only one possible outcome to all events in the universe. A follower of the narrow frequency interpretation of probability could assert that no event can be said to have probability, since there is only one universal outcome. Under the rival Bayesian interpretation of probability, there is no objection to using probabilities to represent a lack of complete knowledge of outcomes.“

“Die Theorie der Schleifenquantengravitation (Loop-Quantengravitation, Loop-Theorie, engl. loop quantum gravity) ist ein Ansatz für eine Theorie der Quantengravitation, d. h. eine Theorie zur Vereinigung der Quantenphysik mit der allgemeinen Relativitätstheorie. Diese Vereinigung gilt heute als eine der größten Herausforderungen in der Physik.
Durch die Schleifenquantengravitation wird der Raum als dynamisches quantenmechanisches Spin-Netzwerk beschrieben, das durch Diagramme aus Linien und Knoten anschaulich darstellbar ist. Eine Konsequenz aus dieser Theorie wäre die Quantisierung von Raum und Zeit im Bereich der Planck-Länge (ca. 10−35 m) bzw. Planck-Zeit (ca. 10−43 s). Auf diesen Größenordnungen verliert die Welt ihre im Alltag angenommene Kontinuität, wobei alles quantisiert beschrieben wird, auch die Gravitation und folglich auch die Geometrie.“

“Freud was swift to pickup Bleuler's concept of ambivalence, applying it to areas he had previously dealt with in terms of ambiguous language, or the persistent co-existence of love and hatred aimed at the same person. Freud also extended the scope of Bleuler's term to cover the co-existence of active and passive trends in the same instinctual impulse - what Freud called "pairs of contrary component instincts" such as looking and being looked at.
Karl Abraham explored the presence of ambivalence in mourning – something he thought to be a universal phenomenon. Others in psychoanalysis have traced the roots of contradictory impulses (usually love and hate) to very early stages of psychosexual development.
Defences against feeling both of the two contradictory emotions include psychological repression, isolation and displacement. Thus, for example, an analysand's love for his father might be quite consciously experienced and openly expressed – while his "hate" for the same object might be heavily repressed and only indirectly expressed, and thus only revealed in analysis. A drug addict may feel ambivalently about their drug of choice; they know that the drug has a destructive effect on their lives (socially, financially, medically, and otherwise), while simultaneously seeking and using it because of the pleasure they get from the drug's usage.“
