Math Links for Week Ending Oct. 18th, 2019

Sometimes when things are free, you get what you pay for. But other times, like this one, a super powerful software package that had a price tag, has become free. In this case that is the Autograph dynamic math package. I have always liked this but because there was a cost, I never bothered with it since we already had things like Desmos and Geogebra (and here in Ontario, Geometer's Sketchpad) available for free to teachers and students. So now everyone can try Autograph out.

This initial launch brings PC and Mac (depends on OS) desktop versions.

Soon, we will add a new Mac version and a web application version for mobile devices.

Vocabulary is a roadblock for students who struggle with mathematics, and for many reasons:

Though this is science related, I think the sentiment of persistence and hard work are the order of the day with this post of a Nobel Prize winner's rejection letter of her research from Nature. Something for our students to see.

This is the rejection letter for the work that just won the Nobel Prize. Don’t stop believing!
