History of the British canal system The British canal system of water transport played a vital role in the United Kingdom's Industrial Revolution at a time when roads were only just emerging from the medieval mud and long trains of packhorses were the only means of "mass" transit by road of raw materials and finished p...
In a purely economic sense, inflation refers to a general increase in price levels due to an increase in the quantity of money; the growth of the money stock increases faster than the level of productivity in the economy. The exact nature of price increases is the subject of much economic debate, but the word inflation...
Newton's Laws of Motion are: Newton's Laws are all contained in a more general principle called conservation of momentum. Momentum is mass times velocity, and in a system that is not disturbed from outside, the total momentum stays constant. Thus: Suppose you are standing on very slick ice. You weigh 50 kg. You fire a ...

Anemia (uh-NEE-me-uh) is a condition in which your blood has a lower than normal number of red blood cells. Anemia also can occur if your red blood cells don't contain enough hemoglobin (HEE-muh-glow-bin). Hemoglobin is an iron-rich protein that gives blood its red color. This protein helps red blood cells carry oxygen...
The computer is also time-efficient when performing integer multiplication by powers of 2. Therefore, it is an efficient method for scan-converting straight lines. To accomplish this, the algorithm always increments either x or y by one unit depending on the slope of line. The increment in the other variable is determi...
A map projection is a systematic transformation of the latitudes and longitudes of locations from the surface of a sphere or an ellipsoid into locations on a plane. Maps cannot be created without map projections. All map projections necessarily distort the surface in some fashion. Depending on the purpose of the map, s...
