The canonical hours mark the divisions of the day in terms of periods of fixed prayer at regular intervals. A Book of Hours normally contains a version of, or selection from, such prayers. The practice of daily prayers grew from the Jewish practice of reciting prayers at set times of the day: for example, in the Book of Acts, Peter and John visit the temple for the afternoon prayers (Acts 3:1). Psalm 119:164 states: "Seven times a day I praise you for your righteous laws" which is among the scriptural quotes in the attestation of Saint Symeon of Thessaloniki that commences "The times of prayer...

A random number book is a book whose main content is a large number of random numbers or random digits. Such books were used in early cryptography and experimental design, and were published by the Rand Corporation and others. The Rand corporation book A Million Random Digits with 100,000 Normal Deviates was first published in 1955 and was reissued in 2001. Random number books have been rendered obsolete for most purposes by the ready availability of random number generators running on electronic computers. However they still have niche uses, particularly in the performance of experimental music...

Brainfuck is an esoteric programming language noted for its extreme minimalism. The language consists of only eight simple commands and an instruction pointer. It is designed to challenge and amuse programmers, and was not made to be suitable for practical use. It was created in 1993 by Urban Müller. == Language design == Urban Müller created brainfuck in 1993 with the intention of designing a language which could be implemented with the smallest possible compiler, inspired by the 1024-byte compiler for the FALSE programming language. Several brainfuck compilers have been made smaller than 200...

The patellar reflex or knee-jerk is a deep tendon reflex and is a myotatic reflex. == Mechanism == Striking the patellar ligament with a reflex hammer just below the patella stretches the muscle spindle in the quadriceps muscle. This produces a signal which travels back to the spinal cord and synapses (without interneurons) at the level of L4 in the spinal cord, completely independent of higher centres. From there, an alpha-motor neuron conducts an efferent impulse back to the quadriceps femoris muscle, triggering contraction. This contraction, coordinated with the relaxation of the antagonistic...

Motion, the process of movement, is described using specific anatomical terms. Motion includes movement of organs, joints, limbs, and specific sections of the body. The terminology used, describes this motion according to its direction relative to the anatomical position of the joints. Anatomists use a unified set of terms to describe most of the movements, although other, more specialized terms are necessary for describing the uniqueness of the movements such as those of the hands, feet, and eyes. In general, motion is classified according to the anatomical plane it occurs in. Flexion and extension...

LOLCODE is an esoteric programming language inspired by lolspeak, the language expressed in examples of the lolcat Internet meme. The language was created in 2007 by Adam Lindsay, researcher at the Computing Department of Lancaster University. The language is not clearly defined in terms of operator priorities and correct syntax, but several functioning interpreters and compilers already exist. One interpretation of the language has been proven Turing-complete. == Language structure and examples == LOLCODE's keywords are drawn from the heavily compressed (shortened) patois of the lolcat Internet...
