Interesting blog links - math and memory

Blog Link: Mind Games harder for Kids at Eide Neurolearning Blog.

Blog Link: Homeschool Math Blog - ranges from simple to complex mathematical posts, quite interesting! Jumped from here to the link on 'online maths newspaper with funny headlines' at The Sum (think, the 'Sun' tabloid).

Blog Link: Casting Out Nines <-- this looks like it could be interesting, I'll have to check back later.

and now.... a paragraph from the math text I'm currently admiring.. the 1953 'Third Course in the New Mathematics' by Edgerton and Carpenter:

Long before this dam was begun, engineers had to do an enormous amount of mathematical work. Without the knowledge of arithmetic, algebra, geometry and trigonometry, as well as higher mathematics, they never could have planned this gigantic structure.

Just for the record - I'll state that this is an eighth-grade level math book -- and I am currently admiring it for the way it keeps stressing what math is used for, frames problems in the sections on real world problems (explaining textile manuf., machinists' work, farm issues and the like along the way) with real world reasoning and solutions, and reminds the students that their future business goals depend on knowing enough math to do their work and keep their finances in order. By the last 1/5 of the book - they are covering quadratic equations, factoring, stock market dividends, insurance policies and a special section on aerial navigation. Just a beautiful hardback book - and only a little over 5"x7.5", 490 pgs.

If you've gotten through all that - then you are worthy of reading this (eventually):
The Mathematical Realm of Nature by Michael S. Mahoney, Princeton University. A fascinating online article.
