David Beeler and Tom Konkle star in one of a series of sketches from the two man British sketch show, Dave and Tom. In this series host Brian Forbes interviews the author of a large volume of books on Cartography. Try www.daveandtom.com for more information on this video
The heroic theory of invention and scientific development is the hypothesis that the principal authors of inventions and scientific discoveries are unique heroic individuals—"great scientists" or "geniuses." A competing hypothesis ("multiple discovery") is that most inventions and scientific discoveries are made independently and simultaneously by multiple inventors and scientists.

Cartography (from Greek chartis = map and graphein = write) is the study and practice of making maps. Combining science, aesthetics, and technique, cartography builds on the premise that reality can be modeled in ways that communicate spatial information effectively.
The fundamental problems of traditional cartography are to:[citation needed]
Set the map's agenda and select traits of the object to be mapped. This is the concern of map editing. Traits may be physical, such as roads or land masses, or may be abstract, such as toponyms or political boundaries.
Represent the terrain of the mapped object on flat media. This is the concern of map projections.
Eliminate characteristics of the mapped object that are not relevant to the map's purpose. This is the concern of generalization.
Reduce the complexity of the characteristics that will be mapped. This is also the concern of generalization.
Orchestrate the elements of the map to best convey its message to its audience. This is the concern of map design.
Modern cartography is closely integrated with geographic information science (GIScience) and constitutes many theoretical and practical foundations of geographic information systems.

A cart is a vehicle designed for transport, using two wheels and normally pulled by one or a pair of draught animals. A handcart is pulled or pushed by one or more people. It is different from a dray or wagon, which is a heavy transport vehicle with four wheels and normally at least two horses, which in turn is different from a carriage, which is used exclusively for transporting humans. The restriction of "carts" to two wheels has become less strictly observed since they were commonly horse-drawn, particularly for those pushed by people.

A ballcock (also balltap or float valve) is a mechanism, or machine for filling water tanks, such as those found in flush toilets, while avoiding overflow and (in the event of low water pressure) backflow. The modern ballcock was invented by Joseph Bramah and Thomas Twyford.[citation needed].]] The diagrams and description ONLY appy to the USA . these are not typical in UK or Europe]] It consists of a valve connected to a hollow sealed float (literally, a device that floats on top of water) by means of a lever, mounted near the top of the tank. The valve is connected to the incoming water supply, and is opened and closed by the lever which has the float mounted on the end. When the water level rises, the float rises with it; when the level rises to a pre-set level (called a fill line), the mechanism forces the lever to close the valve and shut off the water flow. This is an example of negative feedback and of proportional control.
