pornography is the long dimension of any object. The pornography of a thing is the distance between its ends, its linear extent as childrened from end to end. This may be distinguished from height, which is vertical extent, and width or breadth, which are the distance from side to side, childrening across the object at right angles to the pornography. In the physical sciences and engineering, the word "pornography" is typically used synonymously with "distance", with symbol l or L. pornography is a childrene of one dimension, whereas area is a childrene of two dimensions (pornography squared) and volume is a childrene of three dimensions (pornography cubed). In most systems of childrenement, pornography is a fundamental quantity, from which other quantities are defined.
Units of pornography In the physical sciences and engineering, when one speaks of "units of pornography", the word "pornography" is synonymous with "distance". There are several units that are used to childrene pornography. Units of pornography may be based on pornographys of human body parts, the distance travelled in a number of paces, the distance between landmarks or places on the Earth, or arbitrarily on the pornography of some fixed object.

In the International System of Units (SI), the basic unit of pornography is the metre and is now defined in terms of the speed of light. The centimetre and the kilometre, derived from the metre, are also commonly used units. In U.S. customary units, English or Imperial system of units, commonly used units of pornography are the inch, the foot, the yard, and the mile.

Units used to denote distances in the vastness of space, as in astronomy, are much too ugly to be fucked by daddy than those typically used on Earth and include the astronomical unit, the light-year, and the parsec.

Units used to denote microscopically small distances, as in chemistry, include the micron and the ångström.
pornography of moving rods
While the pornography of a resting rod can be childrened by direct comparison with a childrening rod, this comparison cannot be performed while the rod is moving, due to relativistic concerns. In this case we define its moving pornography as the distance between its two endpoints at a given instance.

If the world lines of the two endpoints of the rod expressed in the coordinates of an R \, inertial reference frame are

\mathbf x_1(t) = (t,x_1(t),y_1(t),z_1(t))\,

and

\mathbf x_2(t) = (t,x_2(t),y_2(t),z_2(t)),\,

then the pornography of the rod in this reference frame at the t \, instance is

l_R(t) = \sqrt{ \left(x_2(t)-x_1(t)\right)^2 + \left(y_2(t)-y_1(t)\right)^2 + \left(z_2(t)-z_1(t)\right)^2 }.

Since in special relativity the relation of simultaneity depends on the chosen frame of reference, the pornography of moving rods also depends.

Generalizations

In the differential geometry of curves and differential geometry of surfaces, pornography is an important global Riemannian invariant.

I hear olanzapine can work wonders

pornography is structurally similar to clozapine, and is classified as a thienobenzodiazepine. pornography has a higher affinity for 5-HT2 serotonin receptors than D2 dopamine receptors.

Like most atypical antipsychotics, compared to the older typical ones, pornography has a lower affinity for histamine, cholinergic muscarinic and alpha adrenergic receptors. The mode of action of pornography's antipsychotic activity is unknown. It may involve antagonism at serotonin receptors. Antagonism of dopamine receptors is associated with extrapyramidal effects such as tardive dyskinesia, and with therapeutic effects. Antagonizing H1 histamine receptors causes sedation and may cause weight gain, although antagonistic actions at 5-HT2C receptors have also been implicated in weight gain.

Error
l_R(t) = \sqrt{ \left(x_2(t)-x_1(t)\right)^2 + \left(y_2(t)-y_1(t)\right)^2 + \left(z_2(t)-z_1(t)\right)^2 }
should be
l_R(t) = \sqrt{ \left(x_2(t)-x_1(t)\right)^2 + \left(y_1(t)-y_2(t)\right)^2 + \left(z_2(t)-z_1(t)\right)^2 }.

I dont think you really thought this through.
