Talk tonight at Cal Poly, San Luis Obsipo Aerospace Engineering Graduation Banquet

I am giving a talk tonight at Cal Poly, San Luis Obsipo Aerospace Engineering Graduation Banquet. It is taking place at the same restaurant where I had my graduation so many years ago, Madonna Inn.
Why was I invited to give this talk?
It is because I was the first woman ever to graduate from that department.
Over the years, from being the only women in my classes and at work, I saw more women join the ranks as engineers. But women still continue to avoid engineering as a career.
Surprising, since it is a great desk job, pay extremely well and has a lot of flexibility. It is easier to integrate with a home life and having children than are many other careers.
My company Loral has been exceedingly supportive over the years when I had young children and did not want to work full time.
But yet, women continue to be afraid of it. Why?

My math books for children


I am announcing the publication of my two new math books. These are for children in middle schools. My daughter still continues to fear percents, so I guess even some adults might find them useful. The books are: VERBAL FRACTIONS and VERBAL PERCENTS.

The idea is for children to learn these procedures verbally, i.e. doing all work done in head, without any writing. The process builds conceptual understanding and speed. The books will be available in bookstores and of course at the big online places such as Barnes and Noble and Amazon.com. Please check them out, or at website www.mathlesson.com.

Complex Confusing Confounding Codes

I am trying to edit and fix my tutorial on Turbo codes, at www.complextoreal.com. I remember what a difficult time I had writing that section. The editing is not much easier. Many of you have written me about errors and points of confusion in the Turbo Tutorial. Please do so again. I keep replacing my computer every one-two years and keep losing all my saved emails. So if you have specific ideas about improvement, changes, please let me know.

I am also wondering who the main developers are of the Turbo (using MAP and SOVA decoding algorithms) are? If you have companies that make these chips, write.
