Concern regarding teachers and how they transfer anxiety to some students

A new report published in the Proceedings of the National Academies of Science claims female teachers who show an anxiousness in math can share that attitude with female students.

The study was based on 17 first- and second-grade elementary school teachers, along with 52 boys and 65 girls.  At the beginning of the school year, researchers learned boys' and girls' math achievement didn't correlate depending on the attitude of their teacher.  

Boys weren't affected, but girls who began to believe boys are naturally better at math yielded lower grades.

"We are not sure whether it's something overt, whether it's non-verbal behavior or perhaps (teachers are) not spending much time on the subject," said Susan Levine, University of Chicago psychology and human development professor, co-author of the “Female Teachers' Math Anxiety Affects Girls' Math Achievement” study.  "It's not just a teacher's knowledge of the subject, but there' something about their feeling about the discipline."

This is a significant problem since there is a high demand for scientists, engineers and mathematicians, as these are in-demand jobs that help stimulate the economy.  However, men continue to dominate the engineering and IT jobs, and researchers believe it's detrimental to research to "dismiss 50%" of researchers because they are women.

The National Survey of Science and Mathematics Education indicates more than 90% of all elementary school teachers in the U.S. are women -- an inadequate level of mathematics study is required to receive a teaching certificate, which is something that may be addressed in the future.

A) Pigeon hole of course always trumps, your stupid to think otherwise.

B) However many files can be compressed also... lower than their original size. Your stupid to think otherwise.

C) Your math is bad. You assume only based upon random data. I do not. If the file is uncompressable, it is UNCOMPROMISABLE.

The system is designed to be used upon skewed data sets. Re-run your math now to try to account for text, software languages, and the likes.

You tried, I will give you credit, however you completely failed to apply basic concepts in your attempt to act high and mighty.

As for showing how you got your work, "A Brilliant mind". He showed how he did some math through his life, but other maths he would just do, and never explain how he got the answer.

There are math geniuses who do not ever need to 'do the steps' to get the answer. They can adequately walk through complex math principles merely telling the answer. 10 internet points if you can name one of the conditions that allows this.

You said in your previous post that this will bring maximum entropy to "ANY give file" (sic).

Except Donovan just.... proved otherwise. Poor Fella.

Furthermore, yes, its great that Fermat jotted random theorems in his notes and then noted "I can prove this... but I need to feed my cat". Well pat on the back for him, good job. Except that none of his work serves as a firm basis for other scientific works because of the lack of rigorous proof.

The main point however, was never that you didn't know math. The point of your middle school math class, or any other topical class wasn't to teach you the pitiful content matter at the time, but rather to teach you to follow direction and instruction.

But /thread.

If you want to go through life ignoring what people in charge tell you to do, I wish you the best of luck. You should go point a gun at a cop and then argue with him when he tells you to put it down

On true random data 8 to 8 is the best of entropy for the given data. That is indeed the lowest entropy of the file.

When data gets a little 'lopsided' then you can get better than 8 to 8 ratios.

So no, he did not prove anything.
