As a homeschooling mom, I need to constantly be on the alert against brain-drain. This is a condition where any information sought or stored in your mind that would be relevant, applicable or interesting to an ADULT is mysteriously shoved into the back recesses of your cranium...only leaving things like 4th grade mathematics, 2nd grade phonics, and Schoolhouse Rock songs about the parts of speech at the very forefront of your thoughts. Don't get me wrong--I enjoy the refresher course on these elementary subjects. It's just that I have been feeling the need to THINK more, and more deeply... and think thoughts don't come with a cutsie jingle to help remember them? Crazy, huh?
Anyway, I highly recommend visiting http://www.thegreatcourses.com/. They essentially bring great professors in from Universities all over the country, and tape all the lectures from their most popular courses. They are pretty expensive, but I have found some at my library. The girls and I have been watching (don't laugh): "The Joy of Thinking: The Beauty and Power of Classical Mathematical Ideas". The three of us are all at about the same level of competency in mathematics (only a slight hyperbole), and I thought that I was up to a challenge.
It has been fascinating! Lots to share, but this was Professor Starbird's illustration that seemed so mind numbingly applicable for today:
"In 2003, the national debt was 6.6 trillion. If a legislator presented a bill to pay down the national debt, claiming that this bill would reduce the national debt by $1 million dollars per hour...how long would it take to pay off the national debt? Well, at 24 hours a day, every day, it would take about 660 years to pay down the debt."
Yikes. That seems like something way beyond what our children and grandchildren will have to deal with.
Math Trivia:
1, 1, 2, 3, 5, 8, 13, 21, 34, 55...*
What do mathmeticians call this special sequence of numbers?
*For reasons that are still mysterious to biologists and mathematicians, this number sequence is seen all over the natural world....in the spirals on pineapple and pinecones, the spiral patterns in the center of daisies and other composite flowers...in the reproductive predictions of pairs of rabbits...all over!
