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 (dinghy)

The Tadpole is a small dinghy with an approximate length of 6 feet (2 m) and an approximate beam of 3¹⁄₂ feet. Its gaff rig has 30 square feet (3 m²) of sail area.

Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Bud

In botany, a bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of a stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately. Buds may be specialized to develop flowers or short shoots, or may have the potential for general shoot development. The term bud is also used in zoology, where it refers to an outgrowth from the body which can develop into a new individual.

Overview

The buds of many woody plants, especially in temperate or cold climates, are protected by a covering of modified leaves called scales which tightly enclose the more delicate parts of the bud. Many bud scales are covered by a gummy substance which serves as added protection. When the bud develops, the scales may enlarge somewhat but usually just drop off, leaving on the surface of the growing stem a series of horizontally-elongated scars. By means of these scars one can determine the age of any young branch, since each year's growth ends in the formation of a bud, the formation of which produces an additional group of bud scale scars. Continued growth of the branch causes these scars to be obliterated after a few years so that the total age of older branches cannot be determined by this means.

Frequent contributors include Phil Baines, Steven Heller, Steve Hare, Richard Hollis, Robin Kinross, Jan Middendorp, J. Abbott Miller, John O’Reilly, Rick Poynor, Alice Twemlow, Kerry William Purcell, Steve Rigley, Adrian Shaughnessy, David Thompson, Christopher Wilson and many others.

Other contributors have included Nick Bell (creative director from issues 27-57), Gavin Bryars, Anne Burdick, Brendan Dawes, Simon Esterson (art director since issue 58), Malcolm Garrett, Anna Gerber, Jonathan Jones, Emily King, Ellen Lupton, Russell Mills, Quentin Newark, Tom Phillips, Robin Rimbaud, Stefan Sagmeister, Sue Steward, Erik Spiekermann, Teal Triggs, Val Williams and Judith Williamson.

John Barleycorn Must Die

John Barleycorn Must Die is the fourth studio album by the English rock band Traffic, released in 1970, on Island Records in the United Kingdom, and United Artists in the United States, catalogue UAS 5504. It peaked at number 5 on the Billboard 200, their highest charting album in the US, and has been certified a gold record by the RIAA. In addition, the single "Empty Pages" spent eight weeks on the Billboard Hot 100, peaking at number 74. The album was marginally less successful in the UK, reaching number 11 on the UK Albums Chart.

Background and content

In late 1968, Traffic disbanded, guitarist Dave Mason having left the group for the second time prior to the completion of the Traffic album. In 1969, Steve Winwood joined the supergroup Blind Faith, while drummer/lyricist Jim Capaldi and woodwinds player Chris Wood turned to session work. Wood and Winwood also joined Blind Faith's drummer Ginger Baker in his post-Blind Faith group Ginger Baker's Air Force for their first album.
