	Ball (mathematics) - Wikipedia, the free encyclopedia
		A synonym for ball (in geometry or topology, and in any dimension) is disc (or disk); however, a 3-dimensional ball is generally called a ball, and a 2-dimensional ball (e.g., the interior of a circle in the plane) is generally called a disc.
		In mathematics, a ball is the inside of a sphere; both concepts apply not only in 3D but also for lower and higher dimensions, and for metric spaces in general; ball even applies for topological spaces in general.
		in taxicab geometry) a ball is a square with the diagonals parallel to the coordinate axes

		During their time as students of mathematics they first formulated, and then concretized, deep seated beliefs about mathematics and what it means to learn and teach mathematics.
		So, a belief that learning mathematics is "all about learning algorithms" may manifest itself as a belief that teaching mathematics is "all about teaching algorithms," and an experience that "all problems have one solution" may manifest itself in the teaching that "all problems must have one solution." Changing Beliefs Robust beliefs are difficult to change.

	The Mathematics of Juggling
		The first ball is tossed at time periods 0, 3, 6..., the second at times 1, 4, 7..., and the third ball at times 2, 5, 8....
		The result is that the first and third balls both move in shower patterns but in opposite directions, and the second ball weaves between the two showers in a cascade rhythm.
		For example, the sequence 21 leads to both balls landing simultaneously in the same hand (although more complicated variants of site-swap notation permit more than one ball to be caught or thrown at the same time, a feat jugglers call multiplexing).

	Investigations: Spotlight (Site not responding. Last check: 2007-10-08)
		The pre-service teachers who enter my mathematics methods course have experienced a minimum of 14 years learning mathematics via traditional instruction (i.e., teaching of mathematics involves clear explanations followed by sufficient practice) as determined from their written reflections.
		As their mathematics methods instructor, there is no way for me to predict which textbooks or curricula my future elementary teachers will have access to or be required to use.
		Learning from my past mistakes, I know that asking pre-service teachers to examine mathematics curriculum or observe mathematics classrooms without structure and guidance is ineffective since they have trouble identifying "What they should look for." As a result, the pre-service teachers are given specific assignments during their field experiences.

	Title
		One might assume that since many PSTs are mathematics majors in college, helping them fix the gaps in their knowledge of division of fractions—a mathematics topic that is typically taught for the first time in elementary school, but is nonetheless reviewed repeatedly in junior high and high school—would be a relatively quick and easy task.
		This study examines the mathematical understandings of the eight PSTs for clues as to why understanding nonstandard reasoning was so difficult for them, even after receiving substantial instruction to develop rich conceptions of division of fractions.
		All eight subjects were either juniors or seniors majoring in mathematics, and typically had two or fewer math courses remaining to take before graduation.

		This book is given up to the consideration of the motion of particles or bodies in free space either in known orbits, or under the action of known forces, or under their mutual attraction; and in particular to indicating how the effects of disturbing forces may be calculated.
		The demonstrations throughout the book are geometrical, but to readers of ordinary ability are rendered unnecessarily difficult by the absence of illustrations and explanations, and by the fact that no clue is given to the method by which Newton arrived at his results.
		But, if the state of mathematical knowledge in 1669 or at the death of Pascal or Fermat be compared with what was known in 1700 it will be seen how immense was the advance.
