Red is the color at the end of the spectrum of visible light next to orange and opposite violet. It is evoked by light with a predominant wavelength of roughly 620–740 nm. Red is one of the additive primary colors of light, along with green and blue, which in RGB color systems are combined to create all the colors on a computer monitor or television screen. It is also one of the subtractive primary colors, along with yellow and blue, of the RYB color space and traditional color wheel used by painters and artists. Reds can vary in shade from very light pink to very dark maroon or burgundy; and in hue from the bright orange-red scarlet or vermilion to the bluish-red crimson. Red was widely used in prehistoric cave art, made with red hematite or iron oxide, or red ochre. Early civilizations in China, the Middle East and Europe made red dyes from the madder plant or from the a tiny insect called the kermes vermilio, Civilizations in the Americas made brilliant reds from another s...
Lilium (members of which are true lilies) is a genus of herbaceous flowering plants growing from bulbs, all with large prominent flowers. Lilies are a group of flowering plants which are important in culture and literature in much of the world. Most species are native to the temperate northern hemisphere, though their range extends into the northern subtropics. Many other plants have "lily" in their common name but are not related to true lilies.
A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The biological function of a flower is to effect reproduction, usually by providing a mechanism for the union of sperm with eggs. Flowers may facilitate outcrossing (fusion of sperm and eggs from different individuals in a population) or allow selfing (fusion of sperm and egg from the same flower). Some flowers produce diaspores without fertilization (parthenocarpy). Flowers contain sporangia and are the site where gametophytes develop. Flowers give rise to fruit and seeds. Many flowers have evolved to be attractive to animals, so as to cause them to be vectors for the transfer of pollen. In addition to facilitating the reproduction of flowering plants, flowers have long been admired and used by humans to beautify their environment, and also as objects of romance, ritual, religion, medicine and as a source of...
STEM is an acronym referring to the academic disciplines of science, technology, engineering, and mathematics. The term is typically used when addressing education policy and curriculum choices in schools to improve competitiveness in technology development. It has implications for workforce development, national security concerns and immigration policy. The acronym arose in common use shortly after an interagency meeting on science education held at the National Science Foundation chaired by the then NSF director Rita Colwell. A director from the Office of Science division of Workforce Development for Teachers and Scientists suggested the change from the older acronym SMET...to STEM. Dr. Colwell, expressing some dislike for the older acronym, responded by suggesting NSF to institute the change.
