K-MODDL > Tutorials > Reuleaux Triangle If an enormously heavy object has to be moved from one spot to another, it may not be practical to move it on wheels. Instead the object is placed on a flat platform that in turn rests on cylindrical rollers (Figure 1). As the platform is pushed forward, the rollers left behind are picked up and put down in front. An object moved this way over a flat horizontal surface does not bob up and down as it rolls along. The reason is that cylindrical rollers have a circular cross section, and a circle is closed curve "with constant width." Winter 2007 - CMPE 240 - Classes - Jack Baskin School of Engineering, UC Santa Cruz Good Luck on the Final: Please use the Forum for Questions. Background Linear Dynamical Systems (sometimes also called Linear Operator Theory refers to a mathematical representation of a physical system that can be represented by a set of 1st order differential equations or 1st order difference (or recursion) equations for discrete time systems.

Pandigital Approximations The digits 1-9 can work some impressive tricks: The first formula, found by B. Ziv in 2004, produces the first 10 digits of pi.

Meet the 12 year old with an IQ higher than Stephen Hawking’s - TNW Shareables As a three year old with a passion for stars he went on a tour of the Holcomb Observatory and Planetarium at Butler University in Indianapolis. This is the day his mother Kristin Barnett would never forget (via the IndyStar): “We were in the crowd, just sitting, listening to this guy ask the crowd if anyone knew why the moons going around Mars were potato-shaped and not round.Jacob raised his hand and said, ‘Excuse me, but what are the sizes of the moons around Mars?’ ”The lecturer answered, and Jacob looked at him and said the “gravity of the planet . . . is so large that (the moon’s) gravity would not be able to pull it into a round shape.”Silence.

An Intuitive Explanation of Fourier Theory Steven Lehar slehar@cns.bu.edu Fourier theory is pretty complicated mathematically. But there are some beautifully simple holistic concepts behind Fourier theory which are relatively easy to explain intuitively. There are other sites on the web that can give you the mathematical formulation of the Fourier transform. I will present only the basic intuitive insights here, as applied to spatial imagery.
