Bunya Pine

Araucaria bidwillii, commonly known as the bunya pine (/ˈbʌnjə/), banya or bunya-bunya, is a large evergreen coniferous tree in the family Araucariaceae which is endemic to Australia. Its natural range is southeast Queensland with two very small, disjunct populations in northeast Queensland's World Heritage listed Wet Tropics. There are many planted specimens on the Atherton Tableland, in New South Wales, and around the Perth metropolitan area, and it has also been widely planted in other parts of the world. They are very tall trees – the tallest living individual is in Bunya Mountains National Park and was reported by Robert Van Pelt in January 2003 to be 51.5 m (169 ft) in height.

Guttation

Guttation is the exudation of drops of xylem and phloem sap on the tips or edges of leaves of some vascular plants, such as grasses, and also a number of fungi. Ancient Latin gutta means "a drop of fluid", whence modern botany formed the word guttation to designate that a plant exudes drops of fluid onto the outer surface of the plant, when the source of the fluid is inside the plant. Guttation happens in a variety of plant species.

Iamb

An iamb (/ˈaɪæm/ EYE-am) or iambus is a metrical foot used in various types of poetry. Originally the term referred to one of the feet of the quantitative meter of classical Greek prosody: a short syllable followed by a long syllable (as in καλή (kalḗ) "beautiful (f.)"). This terminology was adopted in the description of accentual-syllabic verse in English, where it refers to a foot comprising an unstressed syllable followed by a stressed syllable (as in abóve). Thus a Latin word like íbī, because of its short-long rhythm, is considered by Latin scholars to be an iamb, but because it has a stress on the first syllable, in modern linguistics it is considered to be a trochee.

Trochee

In poetic metre, a trochee (/ˈtroʊkiː/) is a metrical foot consisting of a stressed syllable followed by an unstressed one, in qualitative meter, as found in English, and in modern linguistics; or in quantitative meter, as found in Latin and Ancient Greek, a heavy syllable followed by a light one (also described as a long syllable followed by a short one). In this respect, a trochee is the reverse of an iamb. Thus the Latin word íbī, 'there', because of its short-long rhythm, in Latin metrical studies is considered to be an iamb, but since it is stressed on the first syllable, in modern linguistics it is considered to be a trochee.

Leidenfrost effect

The Leidenfrost effect is a physical phenomenon in which a liquid, close to a solid surface of another body that is significantly hotter than the liquid's boiling point, produces an insulating vapor layer that keeps the liquid from boiling rapidly. Because of this repulsive force, a droplet hovers over the surface, rather than making physical contact with it. The effect is named after the German doctor Johann Gottlob Leidenfrost, who described it in A Tract About Some Qualities of Common Water.
