Goldenrod is a color that resembles the goldenrod plant.

A Crayola crayon with this name and color, although a lighter version, was created in 1958.

Color

Color (American English) or colour (Commonwealth English) is the visual perceptual property corresponding in humans to the categories called red, blue, yellow, etc. Color derives from the spectrum of light (distribution of light power versus wavelength) interacting in the eye with the spectral sensitivities of the light receptors. Color categories and physical specifications of color are also associated with objects or materials based on their physical properties such as light absorption, reflection, or emission spectra. By defining a color space colors can be identified numerically by their coordinates.

Because perception of color stems from the varying spectral sensitivity of different types of cone cells in the retina to different parts of the spectrum, colors may be defined and quantified by the degree to which they stimulate these cells. These physical or physiological quantifications of color, however, do not fully explain the psychophysical perception of color appearance.

The science of color is sometimes called chromatics, colorimetry, or simply color science. It includes the perception of color by the human eye and brain, the origin of color in materials, color theory in art, and the physics of electromagnetic radiation in the visible range (that is, what we commonly refer to simply as light).

Greeks (finance)

In mathematical finance, the Greeks are the quantities representing the sensitivity of the price of derivatives such as options to a change in underlying parameters on which the value of an instrument or portfolio of financial instruments is dependent. The name is used because the most common of these sensitivities are denoted by Greek letters (as are some other finance measures). Collectively these have also been called the risk sensitivities,risk measures or hedge parameters.

Use of the Greeks

The Greeks are vital tools in risk management. Each Greek measures the sensitivity of the value of a portfolio to a small change in a given underlying parameter, so that component risks may be treated in isolation, and the portfolio rebalanced accordingly to achieve a desired exposure; see for example delta hedging.

The Greeks in the Black–Scholes model are relatively easy to calculate, a desirable property of financial models, and are very useful for derivatives traders, especially those who seek to hedge their portfolios from adverse changes in market conditions. For this reason, those Greeks which are particularly useful for hedging—such as delta, theta, and vega—are well-defined for measuring changes in Price, Time and Volatility. Although rho is a primary input into the Black–Scholes model, the overall impact on the value of an option corresponding to changes in the risk-free interest rate is generally insignificant and therefore higher-order derivatives involving the risk-free interest rate are not common.

Color (manga)

Color is a Japanese manga anthology written and illustrated by Taishi Zaou and Eiki Eiki. Color was serialized in Dear+, a magazine known for its romantic and non-explicit boys love manga published by Shinshokan, and a tankōbon collecting the chapters released in February 1999.Color is licensed in North America by Digital Manga Publishing which released the manga in June 2009. It is licensed in France by Asuka and in Germany by Egmont Manga.

Reception

Goldenrod

Solidago, commonly called goldenrods, is a genus of about 100 to 120 species of flowering plants in the aster family, Asteraceae. Most are herbaceous perennial species found in open areas such as meadows, prairies, and savannas. They are mostly native to North America, including Mexico; a few species are native to South America and Eurasia. Some American species have also been introduced into Europe and other parts of the world.

Description

Solidago species are perennials growing from woody caudices or rhizomes. Their stems ranges from decumbent (crawling) to ascending or erect, with a range of heights going from 5 cm to over a meter. Most species are unbranched, but some do display branching in the upper part of the plant. Both leaves and stems vary from glabrous (hairless) to various forms of pubescence (strigose, strigillose, hispid, stipitate-glandular or villous). In some species, the basal leaves are shed before flowering. The leaf margins are most commonly entire, but often display heavier serration. Some leaves may display trinerved venation rather than the pinnate venation usual across Asteraceae.

Goldenrod (car)

Goldenrod is an American streamliner car which held the wheel-driven land speed record from 1965 to 1991. It was owned by Bob and Bill Summers, of Ontario, California. Bob Summers drove the car to set the land speed record. The Goldenrod is powered by four fuel injected Chrysler Hemi engines, mounted inline and created a total output of 2,400 bhp. The car was originally built in Southern California and the team included James Crosby.

Before finding their final success, the two brothers contacted a fuel specialist and racing equipment pioneer and inventor named Tony Capanna, owner of Wilcap Co. (at that time in Torrance California). They were having trouble getting the speed they wanted with the 4 engines set in 2 rows side by side. Capanna suggested they put the engines in line and have it streamlined. In this configuration it was called Goldenrod. Capanna advised them to get aerodynamic advice from a Lockheed engineer, Walter Korff. The Goldenrod configuration was refined during a wind tunnel test in the Caltech 10-foot wind tunnel. The resulting drag coefficient of 0.1165, with a front area of 8.53 square feet, is one of the lowest ever achieved for a car.
