Discontinuous electrophoresis (colloquially disc electrophoresis [a]) is a type of polyacrylamide gel electrophoresis. It was developed by Ornstein and Davis. [2] [1] This method produces high resolution and good band definition. It is widely used technique for separating proteins according to size and charge. [3]
In the accompanying illustration, A represents a circular disk of 10 units diameter at rest in an inertial reference frame. The circumference of the disk is times the diameter, and the illustration shows 31.4 rulers laid out along the circumference. B represents a circular disk of 10 units diameter that is spinning rapidly. According to a non ...
Like most other Commodore disk drives, these drives utilize zone bit recording to maintain an average bit density across the entire disk. Formatted capacity is approximately 0.5 megabyte per side, or 1 megabyte (1,066,496 bytes) in 4166 blocks total. [4] [5] [7] The 8050 is a single-sided drive, whereas the 8250 and SFD-1001 are double-sided ...
Examples include the Oceanic OC-118 a.k.a. Excelerator+, the MSD Super Disk single and dual drives, the Enhancer 2000, the Indus GT, Blue Chip Electronics's BCD/5.25, and CMD ' s FD-2000 and FD-4000. Nevertheless, the 1541 became the first disk drive to see widespread use in the home and Commodore sold millions of the units.

Ehrenfest paradox – Circumference of a rotating disk should contract but not the radius, as radius is perpendicular to the direction of motion. The reference frame is fixed to the stationary center of the disk. Then the magnitude of the relative velocity of any point in the circumference of the disk is .

Colour distribution of a Newton disk. The Newton disk, also known as the disappearing color disk, is a well-known physics experiment with a rotating disk with segments in different colors (usually Newton's primary colors: red, orange, yellow, green, blue, indigo, and violet, commonly known by the abbreviation ROYGBIV) appearing as white (or off-white or grey) when it's spun rapidly about its axis.
