Ye olde “Ye”
Have you ever walked past some little shop called “Ye Olde Whatever” and wondered why “the” is spelled “ye”? Well, it comes from ancient runes. The symbol for the “th” sound is called thorn, and it looked like this: þ. So the word “the” actually used to be “þe”, but when European printing presses started showing up in England, they didn’t come with a thorn stamp. So instead of doing the French thing and using “th”, english printers just decided that the letter Y was close enough to thorn, plus this way they’d save on space by only using one letter instead of two.
So when you see a “Ye Olde Shoppe,” remember that it’s just pronounced “the old shop”. Especially since saying “yee” in Old English is saying “ya’ll”, and while it might sound more rustic, “ya’ll old shop” doesn’t really make much sense.
James Watt’s work on developing the steam engine lead to the discovery of what are now called Watt’s curves and linkages. The animation above shows how they are constructed from linking a fixed radius to another with a rod. I tweaked the lengths here to make a lovely heart. With different lengths it is possible to make sections of the red curve almost exactly straight. Watt was able to use this to double the power of a beam engine, and nowadays this is used in the suspension systems of some cars. [more] [more2] [code]

Awesome “recipe”to save a file to a dropbox folder and have it printed. I’m going to do this - then I can go to school and have printed anything I need from my ipad the night before. It uses Dropbox, ifttt.com, and automator. Cool and useful.
Five Learning Models (by Ken Whytock)
Five Learning Models by Ken Whytock from “Professional Learning in effective schools” from Victoria Australia including: Peer observation, study groups, case discussions, lesson study, and examination of student work. I feel that online connections are missing - where is the PLN building? All of these are internal to the school. Just wondering if there is room for a sixth?
