It is like being the ringmaster of a great three-ring circus. It has been said that one can recognize the students on a college campus who have studied the calculus -- they are the students with no eyebrows. In utter astonishment at the incredible applicability of the subject, the eyebrows of the calculus students have receded higher and higher and finally vanished over the backs of their heads."Deltahttp://www.blogger.com/profile/00705402326320853684noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-53897361572358187442016-01-22T06:35:49.890-08:002016-01-22T06:35:49.890-08:00Minday, please do join the Facebook group, 1001 Ma...Minday, please do join the Facebook group, <a href="https://www.facebook.com/groups/1001mathcircles/" rel="nofollow">1001 Math Circles</a>.

I am looking for ways to improve math in our homeschool. I like the idea of exploring math outside of a curriculum so much. I'm hoping I can figure out how it can work for our family. mindyhttp://www.blogger.com/profile/18281399488401861671noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-57392998656175474532016-01-20T01:04:17.167-08:002016-01-20T01:04:17.167-08:00I showed the quadrature of the parabola to my math...I showed the quadrature of the parabola to my math history students last year. It's astounding! (It's also pretty difficult, and you'll probably want to be able to have time to "follow along" on your own paper.)
