Degrees of freedom in mechanics describes the number of independent motions that are allowed to a body, or, in case of a mechanism made of several bodies, the number of possible independent relative motions between the pieces of the mechanism. In the study of complex motor control , there may be so many degrees of freedom that a given action can be achieved in different ways by combining movements with different degrees of freedom.
This issue is sometimes called the degrees of freedom problem. This can only be accomplished if the rider has an independent seat. It must be established and maintained in basic training and refers mostly to the biomechanical articulation of the rear and front legs.
In mathematics freedom is the ability of a variable to change in value. Some equations have many such variables. This notion is formalized as the dimension of a manifold or an algebraic variety. When degrees of freedom is used instead of dimension , this usually means that the manifold or variety that models the system is only implicitly defined. Such degrees of freedom appear in many mathematical and related disciplines, including degrees of freedom as used in physics and chemistry to explain dependence on parameters , or the dimensions of a phase space ; and degrees of freedom in statistics , the number of values in the final calculation of a statistic that are free to vary.

Fluctuations on Freedom
For more specific articles and other uses, see Freedom disambiguation. Main article: Free will. Main articles: Academic freedom , Intellectual freedom , Scientific freedom , Economic freedom , Political freedom , Civil liberties , and Liberty. This is confusing because these two do not mean the same, and in fact what [Isaiah] Berlin calls "the notion of 'negative' freedom" has become largely incorporated in the word freedom , whereas the word liberty in its earlier meaning was much closer to the Latin libertas and in its current meaning reflects a different concept, which is a product of the Anglo-Saxon culture".
According to the Oxford English Dictionary , the Old English frei derived from Sanskrit meant dear and described all those close or related to the head of the family hence friends. Conversely in Latin, libertas denoted the legal state of being free versus enslaved and was later extended to children liberi , meaning literally the free members of the household. Those who are one's friends are free; those who are not are slaves". Categories : Social concepts.quinementamp.ga
Books in Little: A Certain Freedom
Using their corn as the raw material, each week they spend several laborious hours, making tortillas: grinding, kneading, toasting, and filling the baskets for meals. The same day they prepare the tortillas, they cook quesadillas with squash blossoms, served with guacamole, and red beans with cactus or ground avocado leaves. They drink homemade tejate , a cacao-based beverage inherited from pre-Hispanic epochs. Because it depends on the climate and the stability of sunny and rainy periods, it is fortuitous as well.
Economy and money are recurring topics as well. Autonomy and sustainability are essential for the family and each one of its members on a personal level.
Everyone has a given space and responsibilities housekeeping, cultivating, etc. Several spaces of the house are constructed in adobe and metal, the architecture is simple. Each of the spaces has a specific decoration, interior design in accordance with utility, where pragmatic minimalism and a refined sense of the color combine.
In the kitchen, for instance, a series of beautiful and coloured utensils, handmade in clay, are exhibited over a whole wall. They animate the interior, a simplified space that is dark and fresh, built without windows so as not to overheat during the warmest hours of the day. The house sustains itself with few economic resources.
Positive and Negative Liberty
Accumulating material goods or commodities does not seem to be the aim, but rather to live well with what is already owned. Freedom is not an abstract construction here. It is a network, a constellation of decisions, of affective positions, of movements: acts that build an ethic. It is a well-being at this critical moment, precarious and vulnerable, as any human condition, and not yet fully self-sufficient to be an accomplished ideal. It is still a well-being considered as the purpose of daily life, again, considered as an ethic.
It would be fairly plausible, romantic, and idealistic to affirm the absence of conflict between the members of the family. The Navarro would spontaneously share some of their problems to me, and did not share some others. It was an approach, a shared experience, in which each one of us controlled a certain degree of what was being exposed and given.
It is impossible to pretend that it was more than a relationship, as one has a friendship or a love: our mutual presences were determined by tacit frontiers that we would be placing, taking away and re-placing, as time was passing. Some documentary or fiction directors work throughout the shooting on the abolition or the infringement of the frontier of the other, looking for a fusion between the one filming and the one being filmed.
Fascinating films have resulted from this method of psychological intrusion and justly deal with matters of immersion, fusion, annihilation and rebirth, or annihilation and death. The first weeks I filmed exclusively with a hand-held camera, and as time was passing, I stopped feeling the need to film at such a close proximity. I increasingly wanted to film with a tripod, to have stability to give space to the dim phenomena that the movement of my body would have erased.
I began to reduce the depth of field, and to open the frame.

At the beginning, I was only using long-focus lenses and close-up shots, as if I was desperately trying to get closer. By the end of shooting, I was doing the contrary: using long-focus lenses to be able to put myself away. To reduce the depth of the field is analogous to a sculptural gesture, a piece of matter is chosen to be moulded.
I thought about the Rodin Museum in Paris where I live , where unfinished sculptures are exhibited in which human body parts are only sketched, a salient movement coming out of the stone or marble. I thought about the reduced depth of field in these terms, as an allowance to dig a plane into the real, a sharp fringe of visibility, or as a microscope, allowing the viewer to choose where to place the gaze and observe the profusion of details.

If their economy and ethics are constructed on the act of weaving, the threads can therefore be considered the raw material founding the entire sustainability. The thread is made of cotton, it is an organic matter changing with time. It is fragile, and when it is hanging on the backstrap loom, it acquires qualities of constant movement.
