Hurricane Lili
Hurricane Lili was one of only four Atlantic tropical cyclones on record to reach hurricane status in the month of December. The final of thirteen tropical storms in the 1984 Atlantic hurricane season, Lili developed as a subtropical cyclone which originated from a frontal trough to the south of Bermuda on December 12. It tracked southeastward, then northward, slowly attaining tropical characteristics and becoming a hurricane on December 20. Lili turned to the south and southwest, briefly threatening the northern Caribbean islands before weakening and dissipating near the coast of the Dominican Republic. Lili was the longest lasting tropical cyclone outside of the Atlantic hurricane season, as well as the strongest hurricane to form during the month of December. It briefly threatened to pass through the Lesser Antilles as a minimal hurricane, though upon passing through the area as a dissipating tropical depression Lili produced light rainfall and no reported damage.

Plunketts Creek
Plunketts Creek is an approximately 6.2 mile (10.0 km) long tributary of Loyalsock Creek in Lycoming and Sullivan counties in the U.S. state of Pennsylvania. Two unincorporated villages and a hamlet are on the creek, and its watershed drains 23.6 square miles (61.1 km²) in parts of five townships. The creek is a part of the Chesapeake Bay drainage basin via Loyalsock Creek and the West Branch Susquehanna and Susquehanna Rivers.
Plunketts Creek's unique name comes from the first owner of the land including the creek's mouth, and the creek has given its name to two townships (although one has since changed its name). The creek flows southwest and then south through the dissected Allegheny Plateau, through rock from the Mississippian and Devonian eras. Much of the Plunketts Creek valley is composed of various glacial deposits, chiefly alluvium.
Although the Plunketts Creek watershed was clear-cut and home to a tannery, sawmills, and a coal mine in the nineteenth century, today it is heavily wooded and known for its high water quality, fishing, and other recreational opportunities. The watershed now includes parts of the Loyalsock State Forest, Pennsylvania State Game Lands, and a State Game Farm for raising pheasant. Tourism, hunting, and fishing have long been important in the region, and its year-round population is increasing much faster than that of either Lycoming or Sullivan County.

Catalan Numbers
The Catalan numbers, named for the Belgian mathematician Eugène Charles Catalan, are a sequence of natural numbers that are important in combinatorial mathematics. The sequence begins:
1, 1, 2, 5, 14, 42, 132, ...
The Catalan numbers are solutions to numerous counting problems which often have a recursive flavour. In fact, one author lists over 60 different possible interpretations of these numbers. For example, the nth Catalan number is the number of full binary trees with n internal nodes, or n+1 leaves. It is also the number of ways of associating n applications of a binary operator as well as the number of ways that a convex polygon with n + 2 sides can be cut into triangles by connecting vertices with straight lines.

!!!Big Bang!!!
In physical cosmology, the Big Bang is the scientific theory that the universe emerged from a tremendously dense and hot state about 13.7 billion years ago. The theory is based on the observations indicating the expansion of space (in accord with the Robertson-Walker model of general relativity) as indicated by the Hubble redshift of distant galaxies taken together with the cosmological principle.
Extrapolated into the past, these observations show that the universe has expanded from a state in which all the matter and energy in the universe was at an immense temperature and density. Physicists do not widely agree on what happened before this, although general relativity predicts a gravitational singularity (for reporting on some of the more notable speculation on this issue, see cosmogony).
The term Big Bang is used both in a narrow sense to refer to a point in time when the observed expansion of the universe (Hubble's law) began — calculated to be 13.7 billion (1.37 × 1010) years ago (±2%) — and in a more general sense to refer to the prevailing cosmological paradigm explaining the origin and expansion of the universe, as well as the composition of primordial matter through nucleosynthesis as predicted by the Alpher-Bethe-Gamow theory.

What Is A Fairy Tale
A fairy tale is a fictional story that may feature folkloric characters such as fairies, goblins, elves, trolls, giants, and talking animals, and usually enchantments, often involving a far-fetched sequence of events. In modern-day parlance, the term is also used to describe something blessed with princesses, as in "fairy tale ending" (a happy ending) or "fairy tale romance", though not all fairy tales end happily. Colloquially, a "fairy tale" or "fairy story" can also mean any far-fetched story. Fairy tales commonly attract young children since they easily understand the archetypal characters in the story.
In cultures where demons and witches are perceived as real, fairy tales may merge into legendary narratives, where the context is perceived by teller and hearers as having historical actuality. However, unlike legends and epics they usually do not contain more than superficial references to religion and actual places, persons, and events; they take place once upon a time rather than in actual times.
Fairy tales are found in oral folktales and in literary form. The history of the fairy tale is particularly difficult to trace, because only the literary forms can survive. Still, the evidence of literary works at least indicates that fairy tales have existed for thousands of years, although not perhaps recognized as a genre; the name "fairy tale" was first ascribed to them by Madame d'Aulnoy. Literary fairy tales are found over the centuries all over the world, and when they collected them, folklorists found fairy tales in every culture. Fairy tales, and works derived from fairy tales, are still written today

Transhumanism
Transhumanism is an international intellectual and cultural movement supporting the use of science and technology to improve human mental and physical characteristics and capacities. The movement regards aspects of the human condition, such as disability, suffering, disease, aging, and involuntary death as unnecessary and undesirable. Transhumanists look to biotechnologies and other emerging technologies for these purposes. Dangers, as well as benefits, are also of concern to the transhumanist movement. It is often symbolized by H+ or h+.
Although the first known use of the term "transhumanism" dates from 1957, the contemporary meaning is a product of the 1980s when futurists in the United States began to organize what has since grown into the transhumanist movement. Transhumanist thinkers predict that human beings may eventually be able to transform themselves into beings with such greatly expanded abilities as to merit the label "posthuman". Transhumanism is therefore sometimes referred to as "posthumanism" or a form of transformational activism influenced by posthumanist ideals.
Transhumanist foresight of a transformed future humanity has attracted many supporters and detractors from a wide range of perspectives. Transhumanism has been described by one critic, Francis Fukuyama, as the world's most dangerous idea, while one proponent, Ronald Bailey, counters that it is the "movement that epitomizes the most daring, courageous, imaginative, and idealistic aspirations of humanity".
