Tadpole

A tadpole (also called a pollywog or porwigle in British English) is the larval stage in the life cycle of an amphibian, particularly that of a frog or toad. They are usually wholly aquatic, though some species have tadpoles that are terrestrial. When first hatched from the egg they have a more or less globular body, a laterally compressed tail and internal or external gills. As they grow they undergo metamorphosis, during which process they grow limbs, develop lungs and reabsorb the tail. Most tadpoles are herbivorous and during metamorphosis the mouth and internal organs are rearranged to prepare for an adult carnivorous lifestyle.

Having no hard parts, it might be expected that fossil tadpoles would not exist. However, traces of biofilms have been preserved and fossil tadpoles have been found dating back to the Miocene. Tadpoles are eaten in some parts of the world and are mentioned in folk tales and used as a symbol in ancient Egyptian numerals.

Etymology

The name "tadpole" is from Middle English taddepol, made up of the elements tadde, "toad", and pol, "head" (modern English "poll"). Similarly, "polliwog" is from Middle English polwygle, made up of the same pol, "head" and wiglen, "to wiggle".

Tadpole (band)

Tadpole was a New Zealand rock band from Auckland fronted by female vocalist Renée Brennan. The band formed in June, 1994, and, after numerous line-up changes, disbanded in late 2006.

Before 2000

Between the band's beginning and 1999, Tadpole went through so many line-up changes that there soon ended up being no original members left in the band. At one point, Tadpole was almost a girl band as there were three female members.

However, vocalist Renée Brennan and drummer/manager Dean Lawton have been stable members of the band since the late 1990s, just prior to their New Zealand rise to fame.

During that time, the singles "Blind" (Radio release only, 1998), "For Me" (single release, 1999) and "Backdoor" (also a single release, 1999), were released.

They said their song "Backdoor" was "about our struggle thus far to make it in the New Zealand music industry, and the initial frustration of trying to get our music played on radio, TV - or anywhere really. The 'backdoor' part came about because we felt we were never going to be accepted by the student radio stations, we'd just have to come in through the back door somehow. And yes - for those who want to know, the metaphor of anal sex is intended. I liken our struggle to getting buggered over, and over, and over again. In a very loving and tongue in cheek way."

Tadpole (physics)

In quantum field theory, a tadpole is a one-loop Feynman diagram with one external leg, giving a contribution to a one-point correlation function (i.e., the field's vacuum expectation value). One-loop diagrams with a propagator that connects back to its originating vertex are often also referred as tadpoles. For many massless theories, these graphs vanish in dimensional regularization (by dimensional analysis and the absence of any inherent mass scale in the loop integral).

The physics of tadpoles and the word tadpole was invented by Sidney Coleman. The editor was not satisfied, but he changed his mind once Sidney Coleman proposed spermion or lollypop instead. All words are derived from the shape of the Feynman diagram: a circle with a line interval attached to its external side. Tadpole diagrams, in this sense, first appear in the above-mentioned article by Coleman and Glashow, Physical Review v. 134, p.B671 (1964).

Man (Middle-earth)

In J. R. R. Tolkien's Middle-earth books, such as The Hobbit and The Lord of the Rings, the terms Man and Men refer to humankind – in contrast to Elves, Dwarves, Orcs and other humanoid races – and does not denote gender.

The Elves call the race of Men Atani in Quenya, literally meaning "Second People" (the Elves being the First), but also Hildor (Followers), Apanónar (After-born), and Fírimar or Firyar (Mortals). Less charitably they were called Engwar (The Sickly), owing to their susceptibility to disease and old age, and their generally unlovely appearance in the Elves' eyes. The name Atani becomes Edain in Sindarin, but this term is later applied only to those tribes of Men who are friendly to the Elves. Other names appear in Sindarin as Aphadrim, Eboennin, and Firebrim or Firiath.

Origins

The race of Men is the second race of beings created by the One God, Ilúvatar. Because they awoke at the start of the Years of the Sun, while the Elves awoke at the start of the First Age during the Years of the Trees, they are called the Afterborn by the Elves.

Man (Francis Dunnery album)

Man is an album from British musician Francis Dunnery, released in 2001. It saw Francis experimenting with new sounds, most notably programmed drum beats - a departure from what had been the norm in his studio work up to this point. Vocalist/keyboardist Erin Moran (of A Girl Called Eddy) features heavily on the album.
