Discovering the Art of Mathematics (DAoM) Written by: Christine von Renesse Do your students experience the messiness of doing mathematics, searching for patterns, trying and failing in explaining an idea before they come to a complete argument? The continuum of independent thinking Most of my students (non majors and math majors) are happy to believe anything I state about mathematics. converting links from MT to WordPress I had over 1,000 posts in Movable Type that were archived individually, by month and by category. When I switched to WordPress I changed the format of the permanent links to include the date and title instead of the non-portable post ID (which, by the way, MT does not include when you export your blog so your permanent links won’t work if you export and import your blog through MT either). I was concerned that I wouldn’t be able to get those old URLs to forward to WordPress but in the end it wasn’t all that difficult. The easiest was the monthly archive. It used to be “/archive/year_month.html” so I just added a line in the .htaccess to change it to “/archives/year/month” and I was done.

The Tromino Puzzle by Norton Starr To play a physical version of this puzzle, using 21 actual tromino tiles, a single square piece, and an 8×8 checkerboard-like base, first position the single square tile on any one of the 64 square locations on the base.

Mental calculation Mental calculation comprises arithmetical calculations using only the human brain, with no help from calculators, computers, or pen and paper. People use mental calculation when computing tools are not available, when it is faster than other means of calculation (for example, conventional methods as taught in educational institutions), or in a competitive context. Mental calculation often involves the use of specific techniques devised for specific types of problems. Many of these techniques take advantage of or rely on the decimal numeral system. Usually, the choice of radix determines what methods to use and also which calculations are easier to perform mentally. For example, multiplying or dividing by ten is an easy task when working in decimal (just move the decimal point), whereas multiplying or dividing by sixteen is not; however, the opposite is true when working in hexadecimal.

Dendrite (crystal) Manganese dendrites on a limestone bedding plane from Solnhofen, Germany. Scale in mm. A crystal dendrite is a crystal that develops with a typical multi-branching tree-like form. Dendritic crystal growth is very common and illustrated by snowflake formation and frost patterns on a window. Dendritic crystallization forms a natural fractal pattern. Dendritic crystals can form from growth instabilities that occur when the growth rate is limited by the rate of diffusion of solute atoms to the interface.

RGB Classic Games - Utilities for playing Win9x games Win9x software can be run on any x86 computer, as well as many non-x86 platforms. How this is accomplished depends on what operating system your computer is running. Windows 9x operating systems include a copy of DOS and run most Win16 programs, so Win9x is a replacement for those operating systems. Any computer running DOS (MS-DOS/PC-DOS/DR-DOS/FreeDOS) or Windows 1.0 through Windows 3.11 that meets the minimum hardware requirements should be able to install a copy of Windows 95/98/Me. If you want to run a real copy of Windows, but don't already own one, there is a free Windows-compatible operating system called ReactOS, which can be found in the operating systems section. Unix-like operating systems (Linux, Mac OS X) can run many Win9x programs using a native implementation of the Windows API called Wine.
