Alternative names for the poinsettia are Euphorbia pulcherrima, Mexican flame leaf, Christmas star, Winter rose, Noche Buena and Pascua.
*2 : belonging to each day : everyday 3 : commonplace, ordinary
As an employee, Fiona is gifted at solving the difficult problems that arise from time to time, but she is often careless about the quotidian responsibilities of her job.

In Shakespeare's play As You Like It, the character Rosalind observes that Orlando, who has been running about in the woods carving her name on trees and hanging love poems on branches, "seems to have the quotidian of love upon him." Shakespeare's use doesn't make it clear that "quotidian" derives from a Latin word that means "every day." But as odd as it may seem, Shakespeare's use of "quotidian" is just a short semantic step away from the "daily" adjective sense. Some fevers occur intermittently — sometimes daily. The phrase "quotidian fever" and the noun "quotidian" have long been used for such recurring maladies. Poor Orlando is simply afflicted with such a "fever" of love.
Initially used to assess level of consciousness after head trauma, the scale is actually applied to different situations. The scale was published in 1974 by Graham Teasdale and Bryan J. Jennett, professors of neurosurgery at the University of Glasgow. The pair went on to author the textbook Management of Head Injuries (FA Davis 1981, ISBN 0-8036-5019-1), a celebrated work in the field.
GCS is used as part of several ICU scoring systems, including APACHE II, SAPS II and SOFA, as a contribution for the status of the central nervous system. A similar scale, the Rancho Los Amigos Scale is used to assess the recovery of head injury patients.
"Ansel Adams was always precise about exposure times and lens settings, but sometimes vague about when and where he took his pictures. Autumn Moon has been dated as both 1944 and 1948.
"Using lunar tables, topographic maps, weather records and astronomical software, backed by a scouting trip to Glacier Point itself, the researchers believe that Adams pressed the shutter on September 15, 1948 at 7:03 p.m. Pacific Daylight Time.
In Zen it is often said that (by analogy) the finger can point to the moon but is not the moon; likewise words and actions can point towards what is ineffable but cannot make another know it.
- Monocots and eudicots are derived flowering plants, having diverged from each other after palaeodicots had already split from the line.
- A subgroup of great apes containing chimpanzees and gorillas is derived relative to the orangutan, which diverged earliest.
For the sake of precision, biologists often prefer "derived" over "advanced," a term which may inaccurately imply superiority. Although a derived member of a group may have higher fitness in a given environment, this is not always the case. It is quite common for both basal and derived members of a group to exist simultaneously and be well-suited for different ecological niches, or the same niche in different locations.
Metaphorically a bottleneck is a section of a route with a carrying capacity substantially below that characterising other sections of the same route. This is often a narrow part of a road, perhaps also with a smaller number of lanes, or a reduction of the number of tracks of a railway line. It may be due to a narrow bridge or tunnel, a deep cutting or narrow embankment, or work in progress on part of the road or railway.
Sleight of hand is not a branch of magic, but rather the means used by a magician to achieve magical effects. The techniques involved are sometimes difficult and may need months or years of practice before they can be performed proficiently. Sleight of hand is mostly employed in close-up magic, but it can also be used in stage magic.
Many authors prefer the term eigenimage rather than eigenface, as the technique has been used for handwriting, lip reading, voice recognition, and medical imaging.
In layman's terms, eigenfaces are a set of "standardized face ingredients", derived from statistical analysis of many pictures of faces. Any human face can be considered to be a combination of these standard faces. One person's face might be made up of 10% from face 1, 24% from face 2 and so on. This means that if you want to record someone's face for use by face recognition software you can use far less space than would be taken up by a digitised photograph.
Originally string theory was a theory of 1-branes called strings. By the mid-1990s it became apparent that the theory could be extended to also include higher dimensional objects. Typically these objects are non-perturbative features of the theory (meaning they do not appear in perturbation theory) which is partially why early string theorists were unaware of them.
a surface on which a painter mixes colour pigments. A palette may be made of wood, glass, plastic, ceramic tile or other inert
material and can vary greatly in size and shape. The most commonly known type of painter's palette is made of thin wood board designed to be held in the artist's hand and rest on the artist's arm.
a set of colours put on a palette, or in a more general sense, a particular set or quality of colours.
an analogous range of choices in fine arts or design, e. g. Ravel’s orchestral palette.
Palette (computing), a set of colors available in a computer graphics system, or a small window, or section of a window that's readily exessable for quick and frequent menu choices.

The number of minutes before midnight, a measure of the degree of nuclear threat, is updated periodically. The clock is currently set to five minutes to midnight, having been advanced by two minutes on January 17, 2007.
In a general sense, the term debris is used to refer to man-made garbage. The average American discards garbage, also called trash, at the rate of four pounds per day per person, which translates to 600,000 tons per day, or approximately 220 million tons per year. This is almost twice the rate of trash generation per person as most other major countries. Trash levels can be reduced primarily by recycling, re-use, and reduced consumption.
In the social sciences, specifically sociology and sociocultural anthropology, functionalism (also called functional analysis) is a sociological perspective that originally attempted to explain social institutions as collective means to fill individual biological needs. Later, it came to focus on the ways in which social institutions fill social needs, especially social stability. Functionalism is based around a number of key concepts. Firstly, society is viewed as a system – a collection of interdependent parts, with a tendency toward equilibrium. Secondly, there are functional requirements that must be met in a society for its survival (such as reproduction of the population). Thirdly, phenomena are seen to exist because they serve a function [Holmwood, 2005:87]. Functionalism is a major sociological tradition, alongside other schools of thought, such as conflict theory, interactionism, or exchange theory. The theory is associated with Émile Durkheim and more recently with Talcott Parsons.
Length is a measure of one dimension, whereas area is a measure of two dimensions (length squared) and volume is a measure of three dimensions (length cubed). In most systems of measurement, length is a fundamental unit, from which other units are derived.
In anthropology, diffusion theories explain why cultures imitate the ideas or practices of other cultures. Some theories hold that all cultures imitate ideas from one or a few original cultures, the Adam of the Bible, or several cultural circles that overlap. Evolutionary diffusion theory holds that cultures are influenced by one another, but that similar ideas can be developed in isolation.
The theorem is named after economist Kenneth Arrow, who demonstrated the theorem in his Ph.D. thesis and popularized it in his 1951 book Social Choice and Individual Values. The original paper was entitled "A Difficulty in the Concept of Social Welfare" and can be found in The Journal of Political Economy, Volume 58, Issue 4 (August, 1950), pp. 328–346. Arrow was a co-recipient of the 1972 Nobel Prize in Economics.
- Voter 1: A B C
- Voter 2: B C A
- Voter 3: C A B
If C is chosen as the winner, it can be argued that B should win instead, since two voters (1 and 2) prefer B to C and only one voter (3) prefers C to B. However, by the same argument A is preferred to B, and C is preferred to A, by a margin of two to one on each occasion. The requirement of majority rule then provides no clear winner.
