In mathematics , the space of loops or free loop space of a topological space X is the space of loop topology loops from the unit circle S sup 1 sup to X together with the compact open topology . math Omega X mathcal C S 1, X . math That is, a particular function space . In homotopy theory loop space commonly refers to the same construction applied to pointed space s, i.e. continuous maps respecting base point s. In this setting there is a natural concatenation operation by which two elements of the loop space can be combined. With this operation, the loop space can be regarded as a magma algebra magma , or even as an A infinity operad A sub sub space . Concatenation of loops is not strictly associative, but it is associative up to higher homotopy homotopies . If we consider the quotient set quotient of the based loop space X with respect to the equivalence relation of pointed homotopy, then we obtain a group mathematics group , the well known fundamental group &pi sub 1 sub X . The iterated loop spaces of X are formed by applying a number of times. The free loop space construction is right adjoint to the cartesian product with the circle, and the version for pointed spaces to the reduced suspension . This accounts for much of the importance of loop spaces in stable homotopy theory .

Orphan date February 2009 Free drift mode refers to a state of Motion 28physics 29 motion engaged by an object in orbit , whereby constant Aircraft attitude attitude is not maintained. When attitude is not maintained, the object is said to be in free drift, thereby relying on its own inertia to avoid attitude drift. This mode is often engaged purposefully as it can be useful when modifying, upgrading, or repairing an object in space, such as the International Space Station ref Malik, 2006. ref . Additionally, it allows work on areas near the thrusters on the ISS that are generally used to maintain attitude ref Malik, 2005. ref . While in free drift it is not possible to fully use the solar arrays on the ISS. This can cause a drop in power generation, requiring the conservation of energy. This may affect many systems that otherwise require a lot of energy ref Bertels, 2006. ref . The amount of time that an object such as the ISS can remain safely in free drift varies depending on moment of intertia, perturbation torques, tidal gradients, etc. The ISS itself generally can last about 45 minutes in this mode.

In the mathematical theory of free probability , the notion of free independence was introduced by Dan Voiculescu mathematician Dan Voiculescu ref D. Voiculescu, K. Dykema, A. Nica, Free Random Variables , CIRM Monograph Series, AMS, Providence, RI, 1992 ref . The definition of free independence is parallel to the classical definition of independence probability independence , except that the role of Cartesian products of measure space s corresponding to tensor product s of their function algebras is played by the notion of a free product of non commutative probability spaces. In the context of Voiculescu s free probability theory, many classical probability theorems or phenomena have free probability analogs the same theorem or phenomenon holds perhaps with slight modifications if the classical notion of independence is replaced by free independence. Examples of this include the free central limit theorem notions of free convolution existence of free stochastic calculus and so on.

Orphan date February 2009 Flex space is a term used for lightly zoning zoned buildings . It is mainly used when referring to Industry industrial or office space. History Flex space evolved from light industrial warehouses being converted to office space. Businesses that generally occupy these are new dotcoms , mechanic shops, and companies that contract plumbing , Pest organism pest , electrical , and sometimes local church churches and related services. Companies have discovered that on any given work day, a large percentage of their cubes are unoccupied in some cases, up to 50 . Employees travel for work, take vacation, or are working from home in greater numbers than ever before. To avoid having to lease or buy more office space, flex space allows a company to have a higher occupancy of cube space and less wasted work areas. At the beginning of the work day, an employee shows up at work. Cubes are mostly configured in the same way, making them all the same. The employee chooses a cube where he would like to sit, and that is his cube for the day. At the end of the day, he packs up his belongings, either bringing them all home with him or storing them in a locker space. This leaves the cube the same way it was when he came in, and leaves it free and open for someone to use the following day. A large concern with employees in a flex space environment is cleanliness. It is important in a flex space environment to have a strong cleaning staff. External links http www.bizjournals.com baltimore stories 2002 05 06 focus6.html Flex Space on the Rise?

In physics , a free particle is a particle that, in some sense, is not bound by an external force, or equivalently not in a region where its potential energy varies. In classical physics, this means the particle is present in a field freespace. in quantum mechanics, it means a region of constant potential, usually set to zero in the region of interest since potential can be arbitrarily set to zero at any point or surface in three dimensions in space.
