"Today’s hard drives are reaching the technical limits of their ability to increase capacity. Conventional drives have randomly placed nanometer-scale grains for recording each bit of data, but there is a threshold size beyond which the grains become increasingly susceptible to thermal fluctuations, which can cause data loss or corruption. Known as the superparamagnetic effect, this phenomenon has posed the primary technical challenge to surpassing conventional drives’ 1 terabyte capacity barrier."

I think, it's more than a mutation to be called.., rather than an evolution..

BLOG: A student in one of my daughter's high school math class stood up in disgust and exclaimed "Why do we have to learn math for 12 years when we are never going to use any of it?" 

The student’s question got me thinking about the fact that she saw no connection between the mathematics and her future. How might mathematical modeling improve the experience of mathematics for students such as the one in my daughter’s class? 

Read Rachel Levy's blog, "5 Reasons to Teach Mathematical Modeling": t.co/rXrLmcSMiE

What's the compound interest on the loan? How far does the pick up need to be on that parabolic dish? And for the super keen - CT scans and matrix algebra. Oh, how little the realize the importance...
