in mathematics. Developed at the end of the 19th century‚ set theory is now a ubiquitous part of mathematics‚ and can be used as a foundation from which nearly all of mathematics can be derived. In mathematics education‚ elementary topics such as Venn diagrams are taught at a young age‚ while more advanced concepts are taught as part of a university degree. A set is a well defined collection of objects. Georg Cantor‚ the founder of set theory. A set is a gathering together into a whole of definite‚ distinct

It is so basic and flexible that pretty much every story written in existence can be outlined via the plot diagram. And yet‚ there are stories that‚ when outlined‚ twist the plot diagram into interesting shapes‚ which leads me to suspect that there is a missing step in the plot diagram: the elusive

facebookMore Sharing Services Fishbone Diagram Background The Cause & Effect‚ or Fishbone Diagram‚ was first used by Dr. Kaoru Ishikawa of the University of Tokyo in 1943 - hence its frequent reference as a "Ishikawa Diagram". This diagram is used to identify all of the contributing root causes likely to be causing a problem. This methodology can be used on any type of problem‚ and can be tailored by the user to fit the circumstances. Use of this tool has several benefits to process improvement

Reading Response (Diagrams Matter by Stan Allen) “A diagram architecture is not necessary an architecture produced through diagrams.... Instead‚ diagram architecture is an architecture that behaves like a diagram‚ indifferent to the specific means of its realization." (Par. 13) This paragraph points out the answer that beginners architecture students struggled to find. In the process of design‚ I try to find the potential through the translation from reality to the abstract diagram. While I wonder

A Venn diagram is a drawing‚ in which circular areas represent groups of items usually sharing common properties. The drawing consists of two or more circles‚ each representing a specific group or set. This process of visualizing logical relationships was devised by John Venn (1834-1923). Each Venn diagram begins with a rectangle representing theuniversal set. Then each set of values in the problem is represented by a circle. Any values that belong to more than one set will be placed in
