The maintenance requirements on these machines is labor intensive and mirrors those of its horizontal counterpart. 

A hnal application of bend and polish may be applied to new telescopes with hundreds of segments. Plane mirrors are economically made using a continuous polisher, or CP machine. The machine consists of an annulus of pitch about 2.5 times the diameter of the maximum size workpiece to be polished. The work is placed face down on the pitch and constrained from rotating with the pitch annulus by rollers touching the edge of the work. A large flat mirror can be fully polished out in one eight hour shift and the machine holds three pieces at a time (Kodak-CP). 

An analysis which focuses mainly on individual commodities, as conducted by Marx in much of Capital, volume 1, would not be worthy of such close attention to the type of commodities produced. It would not matter whether it was machines or corn or mirrors (Marx 1978 470). In a partial analysis of individual commodities, the theorist can concentrate specifically upon the production of value. For each individual commodity, an assumption can be made that it will be sold in the market place and that elements of the commodity used up in production will be replaced. But for Marx, this formal manner of presentation is no longer sufficient once we consider the total social capital and the value of its product (ibid. 470). The reproduction of the total social capital requires a consideration of both the value and the use-value of an individual commodity, the use for which it is required in the economic system. 

As is well known, the first stage in synthesizing proteins is transcription of genetic code from DNA to messenger RNA (mRNA), a process that depends on RNA polymerase (transcriptase). A strand of nucleotides in RNA mirrors the order of nucleotides in DNA, thus containing information in a certain sequence in which amino acids must be bound to form the corresponding protein. Protein synthesis takes place on ribosomes, which can be represented as certain machines in which proteins and various amino acids are assembled. 

I photocopied a mirror. Now I have an extra photocopy machine. 

You place the device on the cement sidewalk and step on it. This will turn me over in the fourth dimension so that I will be rotated into a mirror image of myself The machine rotates me about a plane that cuts through my body from head to groin. Watch. ...
