The use of computer graphics can be traced as far back as 1940, when Jay Forrester at M.I.T. designed equipment for training new pilots. The digital computer was chosen as the ideal instrument, because of its adaptability and the flexibility with which the machine could be programmed. It was not until a few years later that a radar defense system project named Whirlwind showed the first practical use of computer graphics (see fig. 1.2). Whirlwind is a computer linked to radar sites, and it displays an electronic map of the location on its monitor with plot blips that represent incoming airplanes. Whirlwind is the first vacuum-tube computer capable of drawing lines and points on a computer screen. In 1958, an experimental filmmaker, John Whitney, Sr.,created a short animation by using the analog computer to control the movement of the character. Whitney used the same system to create the opening title sequence of Alfred Hitchcock’s Vertigo. Later Whitney and his brother... details >>>

What do we envisage when we think of Christmas?  It is of course first and foremost a religious Christian celebration, marking the birth of Jesus Christ. For others without the religious penchant, Christmas brings a special time of sharing with family and friends.  One thing however is for sure; Christmas is a time for enjoying age old traditions such as decorating the tree and tucking into Christmas dinner. But where did these festive traditions come from? Here we explore some of the most popular seasonal customs:  The Date25th December: the day Jesus was born - allegedly. However, it is said that the real birth of Christ is more likely to have been in springtime. So why do we celebrate Christmas in mid- winter? One reason stems from the fourth century when Christians began celebrating Christmas in December because this was conveniently the time when pagans were observing the winter solstice, a time for new beginnings that evoked good spirit and family gatherings... details >>>

Hexham Abbey was re-founded as a Medieval Augustinian Priory in 1113 but the part of present building dates from 1180 to 1250. It has suffered much from destructive restoration. The east end was restored in a barbarous manner and the beautiful fourteenth century chapels under the great east window demolished. The church was intended to be cruciform but the nave was never completed until 1908.The choir is of classic Early English form. It's elegant arcade has pointed arches. The triforium above has round arches each framing two pointed ones and above is an almost unique clerestory. The lofty roof is supported by huge blocks of oak with carved floral bosses.The transepts at Hexham are extremely long and imposing. The north transept was built between 1230 and 1240. The elaborately pierced and arcaded western wall combines well with the stone-vaulted eastern wall aisle. The south trancept, built in 1220, has richly arcaded upper walls and against the west side is one of ... details >>>

Number Theory has it's roots in the quest for prime numbers. working out if a number is prime (and if not it's prime factors) is a matter of some considerable interest but it is not easy. We will look at some techniques to solve these difficulties in these articles.Large numbers or small, there are of course some elementary observations which can be made at once. Even numbers and multiples of 5 are recognisable at sight, multiples of 3 respond to a simple and rapid mental check and thanks to a lucky combination of factors those of 7, 11 13 and 37 are found with little effort.Many other of the smaller primes can be eliminated without having to use the laborious process of testing by actual division. These methods obviously dispose of vast quantities of the natural numbers-even numbers and multiples of 3 alone take care of two-thirds of them, for instance-but there remains an infinity of integers which are either prime or have larger prime factors than these methods are equipped to... details >>>
