- California algebra rule highlights basic math difficulties
- Any of us who have ever been in a math classroom know that too many kids lack fundamental arithmetic skills. It is extraordinarily difficult to teach students more advanced skills when their ability to manipulate fractions or even multiply and divide quickly is compromised. So-called automaticity is critical...

- The Mathematics of RAID-6
- RAID-6 supports losing any two drives. The way this is done is by computing two syndromes, generally referred P and Q. The algebra used for this is the algebra of a Galois Field, GF(28). A smaller or larger field could also be used, however, a smaller field would limit the...

- Programming in 6th or 7th grade algebra?I'm all for programming in the same wayI'm for mathematical proofs. Proofs teach you to understand mathematics in a very fundamental way and to force your brain into very painful ways of thinking. However, proofs are only one aspect of the thought process.The danger...

- Standards-obsessed politicians partly to blame for math/sci problems
- From the Atlantic to the Pacific, educators are coming up with the same conclusion – obvious enough to the kids and probably their parents – standardized tests and policies that require kids to learn difficult topics before they're ready actually hurt math and science education. From the...

- MIT students making solar power realistic
- While most solar power installations involving standard photovoltaic cells are simply too expensive to be practical for most installations, a group of MIT graduate students just completed the first "parabolic" solar energy collector. Our algebra and pre-calculus students will remember that beams of light reflected from a parabola will...

- On Orthogonal Reduction to Hessenberg Form With Small Bandwidth
- Numerous algorithms in numerical linear algebra are based on the reduction of a given matrix A to a more convenient form. One of the most useful types of such reduction is the orthogonal reduction to upper Hessenberg form. This reduction can be computed by the Arnoldi algorithm. When A is...

In this Super Techies interview, larger-than-life techie Marc Canter talks with ZDNet's Editor in Chief Dan Farber about his career as a multimedia pioneer.
We need to get back to freethinking and innovation that is core to our roots. Companies like Intel were founded on thoughts like the famous quote from Robert Noyce - "Don't be encumbered by the past, go out and do something wonderful."
