The following article is from The Great Soviet Encyclopedia (1979). It might be outdated or ideologically biased.
in an asynchronous electric machine, a dimensionless quantity equal to the difference between the rate of rotation of a magnetic field n1 and the rate of rotation of the machine’s rotor n2 referred to n1: S = (n1 - n2)/n1. Slip is a fundamental parameter of an asynchronous electric machine; it describes the machine’s operating condition and loading.
a structure used to hoist ships onto shore for inspection or repair or in putting ships in dry dock. A slip consists of an inclined platform with rail tracks leading into the water. The ship is mounted on carriages that move on the rail tracks. After the ship has been raised onto shore, it is transferred to a horizontal work platform. Slips are constructed on the shores of navigable rivers and in marine ports. [23–1675–]
a thick, paste-like mass composed of a mixture of finely ground silicate raw materials and water. It is used in the manufacture of shaped refractory blocks, porcelain and faïence wares, ceramic tiles, and the like.

What does it mean when you dream about slipping?
Stumbling or slipping in a dream may signify that the dreamer is forcing himself or herself to do things incompatible with the dreamer’s nature or destiny.

A numerical value used in describing the performance of electrical couplings and induction machines. In an electrical coupling, slip is defined simply as the difference between the speeds of the two rotating members. In an induction motor, slip is a measure of the difference between synchronous speed and shaft speed.
When the stator windings of an induction motor are connected to a suitable alternating voltage supply, they set up a rotating magnetic field within the motor. The speed of rotation of this field is called synchronous speed, and is given by Eq. (1) or
Eq. (2), where f is the line frequency and p is the number of magnetic poles of the field. The number of poles is determined by the design of the windings. In accord with Faraday's voltage law, a magnetic field can induce voltage in a coil only when the flux linking the coil varies with time. If the rotor were to turn at the same speed as the stator field, the flux linkage with the rotor would be constant. No voltages would be induced in the rotor windings, no rotor current would flow, and no torque would be developed. For motor action it is necessary that the rotor windings move backward relative to the magnetic field so that Faraday's law voltages may be induced in them. That is, there must be slip between the rotor and the field. See Electromagnetic induction, Induction motor
The amount of slip may be expressed as the difference between the field and rotor speeds in revolutions per minute or radians per second. However, the slip of an induction motor is most commonly defined as a decimal fraction of synchronous speed, as in Eq. (3) or Eq. (4).
Here n is the motor speed in revolutions per minute, &ohgr; is its speed in radians per second, and s is the slip, or more properly the per unit slip. Typical full-load values of slip for an induction motor range from 0.02 to 0.15, depending on rotor design. Slip is sometimes expressed in percent of synchronous speed, rather than per unit. If an induction machine is driven faster than synchronous speed, the slip becomes negative, and the machine acts as a generator, forcing energy back into the electrical supply line.

SLIP(Serial Line IP) A communications protocol for dial-up access to TCP/IP networks. It was commonly used to gain access to the Internet as well as to provide dial-up access between LANs. SLIP transmits IP packets over any serial link (dial up or private lines). SLIP has been mostly superseded by the Point-to-Point Protocol (PPP). See CSLIP and PPP.
