Medieval Times The period from 450A.D to 1450 A.D is generally known as the period of history between Ancient Times and Modern Times. This is usually divided into the so called Dark Ages and the High Middle Ages. The Age of Exploration. The start of the middle ages was marked by massive invasions and migrations. The Islamic world had become a civilization of colossal expansive and had imposed a unity of religion and culture on much of southwest Asia and North Africa. Technological advances during the Middle Ages include the following: 1. Printing press- After the Chinese, Johann Gutenberg developed a more reliable and way of printing using a cast type. Gutenberg utilized wooden machines that extracted juices from fruits, attached to them a metal impression of the letters, and pressed firmly the cast metal into a piece of paper, which then made an extract impression on paper. 2. Gunpowder and Canon- appeared around the 9th century A.D, followed by vigorous development of explosive weapons from 1040 A.D about three centuries before it appeared in Europe. From fire-lance using a rocket combination and bamboo tube as close combat weapon, all barrier guns and cannon were constructed at the beginning of the 12th century A.D. 3. Water mill – it was an integral part of the feudal economy. By using suitable mechanism, its rotary motion could be converted to reciprocal motion making it a source of general power. 4. Windmill was used primarily for blowing bellows, filling cloth, forging iron, sawing, weaving and threshing. 5. Mechanical clock- tells time using gears driven by weights that pull the gears at the right pace. 6. Horse Harness and Horse shoe allowed the horse to increase its” attractive” effort five times and for protection. This innovation came from the 7th century A.D china reaching Europe early in the eleventh century, resulting in the horse taking the place of oxen at the plough. In addition, the introduction of the horses’ modes put the horse on the road for pack and wagon. 7. Distillation and Alcohol- the first preparation of strong spirits of wine was made in Europe in the 12th century. As the distillation of perfumes and oil was already known, alcohol was probably produced by accident in the course of some medical preparation. 8. Universities and Scholastics- By the twelfth century, these schools swelled to become universities with set of courses and teaching the seven liberal arts, philosophy and theology. The first and most famous of these was the University of Paris in 1160. In the eleventh century A.D, medical school had been existence in Salermo.  9.

It contained a good summary of the period’s medical knowledge and accurate descriptions of meningitis, tetanus and other diseases. 11. War Weapons such as cross bows, long bows was developed so that they could attack the enemies at long ranges, keeping themselves safe with the protection of wall and fortresses. Soldiers wear body armors and chainmail to protect themselves. 12. Lenses with spectacles- The discovery of lenses resulted in the invention of spectacles in Italy around 1350 A.D. This gave impetus to the study of light or optics. Grosseteste, Dietrich and Roger Bacon explained how a lens could focus light rays and magnify things. The demand for spectacles gave rise to lens grinding/trading and spectacle-makers. 13. The sternpost rudder apparently came also from China. This led to the development of the sail that could be adjusted such that ship voyages could be made in rougher weather. 14. Mariner’s Magnetic Compass- the ability of a natural magnet to show direction was known o the Chinese several centuries ago or about sixth century A.D before it passed to the West or Europe. 15.

Library of Malatesta Novello in Cesena- considered to be first ever public library in the world. 17. Coffee House became popular in Arabic and Ottoman lands. Renaissance ( 14th century -16th century)  The period of rebirth  Beginning of the cultural movement  Rediscovery of ancient texts was accelerated after the fall of Constantinople in 1453.  Technology for printing books was regarded as the most important invention that facilitated dissemination of knowledge and new ideas.  Paracelsus- an alchemist and physician of the Renaissance. Medieval alchemists worked with two main elements: Sulphur and mercury.  The astronomy was based on geocentric model (earth-centered) described by Claudius Ptolemy.  Nicolas Copernicus published “On the Revolutions of the Heavenly Spheres”.  Andreas Vesalius described the anatomy of the brain’s function. He wrote the book “On the Fabric of the Human Body”. Modern Times The booming world population during the nineteenth century onwards demanded that more goods be produced at a faster rate. People needed efficient means of transportation to trade more goods and cover a larger distance. Machines that required animals to operate must thus be upgraded. Faster and easier means to communicate and compute should be developed to established connections between and among nations. All these needs resulted in the development of industries.
