Key Facts

Gyroscopic Couple: The rate of change of angular momentum (\tau) = I\omega\Omega (In the limit).
  • I = Moment of Inertia.
  • \omega = Angular velocity
  • \Omega = Angular velocity of precession.

Blaise Pascal (1623-1662) was a French mathematician, physicist, inventor, writer and Catholic philosopher.

Leonhard Euler (1707-1783) was a pioneering Swiss mathematician and physicist.


A Container Adaptor is a special container with a modified and restricted interface for some special purpose.

  • stack is a last in, first out (LIFO) abstract data type and linear data structure. A stack is characterized by only three operations; elements may be inserted, inspected, or removed only from the top of the stack, which is the last element at the end of the base container.The stack allows to access only the top element.
  • queue is a first in, first out (FIFO) abstract data type and linear data structure. Elements may be added to the back of the queue and are removed from the front of the queue. Both the front and the back of a queue may be inspected. The queue allows to acces only the front and back elements.
  • priority queue is an abstract data type which is like a regular queue or stack data structure, but additionally, each element is associated with a "priority".
