### device:

Disc
* Most discs are designed to create lift when thrown with the flat side up
  - have a natural tendency to fly a particular way, regardless of how they are thrown
* Some discs contain gases
  - proteins
  - fall freely through the magnetic field while others fall slowly
  - have tentacles
* act as shock absorbers, and bulge when under pressure.
* are complex rubber-like structures between the bones of the spine
  - flat, round structures about a quarter of an inch thick
  - large cushions that lie between the individual vertebrae of our spinal columns
  - more abundant than rods
  - one fifth to one third as thick as the neighboring vertebral bodies
  - rubbery pucks of cartilage that act as spacers between the vertebral bones in the spine
  - shock absorbers, that can bulge, rupture or wear down
  - soft tissue bodies that provide padding between the vertebrae
* are the cushioning materials stacked between the vertebrae, or bones in the spinal column
  - cushions or shock absorbers located between each vertebra
  - shock absorbers between each vertebral body
  - very strong tissues, which are filled with a gel
* become increasingly susceptible to tears or rupture as they age.
* brakes work very much like caliper brakes, with a separate disc attached to the hub.
* can also herniate and cause little local back pain
  - be fate-mapped by subjecting fragments to metamorphosis
  - become damaged so that they bulge or tear
* can bulge, herniate, tear, or degenerate
  - hernitate or tear
  - degenerate or lose their shape and support, or they can bulge or rupture
  - deteriorate, or a disc can stick out and press on nerves
  - herniated and lead to neurological deficits such as weakness, numbness and pain
  - shatter or explode, sending pieces flying in all directions
* have a hard outer layer and a soft inner core
  - stronger outer casing with a pliable jelly-like substance inside
* help absorb shock, reduce friction, and facilitate movement
  - to support the spine, and also allow it to move
* herniate because of a congenital weakness of the supporting fibers.
* includes sections.
* is an audio
* protrude and degenerate into the concavity of a curve, into the side of extension.
* serve as shock absorbers of the spine.
* shedding in the parietal eye of the lizard occurs in the absence of a pigment epithelium.
* vary in size and shape of the blade and edge.
* wear out with age or abuse, most frequently at the base of the spine.
+ Flying disc, Mass of the disc: Toys :: Sports equipment
  * All involve spinning the disc to give it gyroscopic stability, and accelerating its mass to a certain velocity. Using these two guidelines, any number of throws are possible. Most discs are designed to create lift when thrown with the flat side up.

### device | disc:

Accretion disc
* are nature's remedy for the angular momentum barrier.
* are, primarily, found around protostars and black holes.
* do have a distribution of temperatures.
* is formed from a massive cloud of gas and dust in the space due to gravitation.

Compact discs
* are made from tough, highly transparent polycarbonate plastic
  - media for data storage
  - small, yet provide high storage capacity
* use pits of varying lengths to represent data.

Diskette
* are extremely sensitive to magnetic fields
  - magnetic disks
  - part of computers
  - thin, plastic flexible disks on which information can be stored magnetically
  - very sensitive to dust and other contaminates
* can melt in an automobile parked in the sun.
* have fragile magnetic media
  - more storage capacity than do cassette tapes
