What is Conceptual: Definition and 874 Discussions
Conceptual art, also referred to as conceptualism, is art in which the concept(s) or idea(s) involved in the work take precedence over traditional aesthetic, technical, and material concerns. Some works of conceptual art, sometimes called installations, may be constructed by anyone simply by following a set of written instructions. This method was fundamental to American artist Sol LeWitt's definition of conceptual art, one of the first to appear in print:
In conceptual art the idea or concept is the most important aspect of the work. When an artist uses a conceptual form of art, it means that all of the planning and decisions are made beforehand and the execution is a perfunctory affair. The idea becomes a machine that makes the art.
Tony Godfrey, author of Conceptual Art (Art & Ideas) (1998), asserts that conceptual art questions the nature of art, a notion that Joseph Kosuth elevated to a definition of art itself in his seminal, early manifesto of conceptual art, Art after Philosophy (1969). The notion that art should examine its own nature was already a potent aspect of the influential art critic Clement Greenberg's vision of Modern art during the 1950s. With the emergence of an exclusively language-based art in the 1960s, however, conceptual artists such as Art & Language, Joseph Kosuth (who became the American editor of Art-Language), and Lawrence Weiner began a far more radical interrogation of art than was previously possible (see below). One of the first and most important things they questioned was the common assumption that the role of the artist was to create special kinds of material objects.Through its association with the Young British Artists and the Turner Prize during the 1990s, in popular usage, particularly in the United Kingdom, "conceptual art" came to denote all contemporary art that does not practice the traditional skills of painting and sculpture. One of the reasons why the term "conceptual art" has come to be associated with various contemporary practices far removed from its original aims and forms lies in the problem of defining the term itself. As the artist Mel Bochner suggested as early as 1970, in explaining why he does not like the epithet "conceptual", it is not always entirely clear what "concept" refers to, and it runs the risk of being confused with "intention". Thus, in describing or defining a work of art as conceptual it is important not to confuse what is referred to as "conceptual" with an artist's "intention".
1. Why is 2(pie)rh multiplied by the dr (change in r) equal to the change in volume?
This is in the case of deriving the moment of inertia of a cylinder; the equation is (change in mass)=2(pie)(radius)(height)(change in radius)(density).Homework Equations

When a ball hits a wall and comes back, it originally had a momentum P. However, when the ball comes back, it has a momentum of -P (as in going in the opposite direction.) According to the law of conservation of momentum, since the ball had an impulse of -2P, the wall must...

Okay I have several questions that have been bothering me for some time now, so bear with me please.

Stars other than our sun normally appear featureless when viewed through telescopes. Yet astronomers can readily use the light from these stars to determine that they are rotating and even measure the speed of their surface. How do you think they can do this?
We have the index of refraction formula of n = \frac{c}{v} which essential states how much of a factor light travels faster in a vacuum than in this medium. Why don't they just have it as n=\frac{v}{c} so it states fractionally how much slower light travels in the medium than the speed of...
To be able to explain in a nutshell to my daughter why you can't go faster than the speed of light does this work:

Hello all,
I have a quantum physics question which is more conceptual and mathematical than anything. Here's the question:
Explain why ψ and its derivative have to be continuous and finite.
First off, this is not a request for a numerical answer. We've started discussing scattering matrices in my High frequency engineering class, and I'm having some trouble understanding wave mechanics. This got no attention in the homework forum, so I'll just copy paste from there.
