Sure - my point was more the general tendency of education to promote logical and critical thinking. I agree it's not an automatic result.

Interestingly, in my country there's been a spirited discussion whether the MAIN goal of education is not so much to pump knowledge and facts into your brain but precisely to learn the ability to reason and be critical. That way, you can handle any situation, even those never envisoned when you were doing your education.

Jan, same discussion going on over here. It comes up as a topic from time to time on NPR. A friend of mine went through the nuclear Navy program and he keeps in touch with some people there. It is getting harder and harder to find qualified candidates that can handle the rigors of the course.

We discussed this in Lounge, "University has no clothes". The problem is, Western education is more and more business oriented, like sale of certain skills to get a job. Things change.

Yes, a big battle brewing at the U of Texas along those lines. The university president is under fire from the governor.

My first day at Intro to EE class, we were told it was an honor to be accepted into the school. As I mentioned before, Motorola, IBM, and TI were pushing UT hard to get guys through digital engineering. Forget analog...that was old school! :rolleyes:

Guys
Sorry to interfere in this «interesting» discussion about education.
(As a side note I have two engineering degrees and one economics degree and on top of that I have very good hearing)

Stuart, maybe you could put up the test one more time (I did not answer last time, but I heard a difference, not only by headphones)

What I find interesting is the test Jan did some months ago (posted in another lounge thread), I have attached the files Jan posted.

They heard a difference, but why did they come to the surprisingly wrong conclusion?

“They described those subtle differences as minor changes in attack and transients and had reported the setting which they thought had the ‘sharpest’ attack as ‘not in the loop”

In my opinion they did not hear the filter frequency response, but the phase shift.

BTW: for those interested in splitting hairs, sorry for my bad English (it’s not my first language) :rolleyes:

Cheers
Stein

There is some evidence that the RIGHT BRAIN is poorly utilized with modern higher education, and therefore does not get developed as well as it should.

The snag is that without knowledge and facts there is not much to reason with or criticise. The likely outcome is people who are ready to criticise stuff they simply don't understand, such as the feminists who claim that physics (that is, physics itself, not the people or institutions of physics) is male-biased. (So God was being a male chauvinist when he decided how electromagnetism should work?)

I've been in recent seminars with a room of 100 teachers and they will readily admit that there are some severe problems in the classroom and students are getting further and further behind and less prepared for college. An 'expert' had put such comments into her presentation and the teachers all agreed.

I'm a tech. Wish I could be better at math but I'm not.

:D What is wrong with acknowledging greatness and using what knowledge has been graciously supplied on this thread; at least that which I can undrestand;)

That is the only reason i suggested we try to better explain in plain English, as much as is possible, what is going on... to reach the widest group of experiences/people.

This is also brain-related. But not related to left-right difference, but to the difference between development of prefrontal cortex that is responsive for higher activity like creativity, and earlier parts of brain responsive for surviving and emotions. Witch-hunting resulted in change of role of women in the society. As the result, when development of prefrontal cortex happens mothers feel anger, fear, anxiety, so it's development is suppressed. Children are pre-programmed to live in society by mother's chemistry. The result is generations of Western people who are better in fight, survival, competition, business, but worse in creativity. It is the fact well explained by science.

To change the situation more than change of education is needed. Education serves the society and follows by it's trends. What is needed, is more of love and protection for pregnant women and mothers, so children would be prepared to live in peace, to be more creative.

Wavebourn and SY. Thank you for trying to help.:)

I couldn’t believe that you were serious about the popcorn group, but in the process of reading the recent very interesting posts, I spotted a person who is really enjoying his popcorn while typing a message here :D

Last year I was at an investment party held by stock broker. One there was still working for university of calif system. I said I might go back to work just to do interesting work with smart interesting people.... thats when he told me I should have no trouble ... there were 800 openings going unfilled because they cant find qualified people.

The party is long over.
 
When recruiters say they can't find qualified people they may actually mean they can't find the 'right kind' of qualified people e.g. cheap, under 45/50, happy to do what they are told, not smarter than the boss. We are supposed to have a shortage of qualified scientists/engineers in the UK, yet experienced and qualified people often find it difficult to even get interviewed.

The same here. Recruiters have certain set of keywords, they need to be "Objective", so if say somebody has in resume for example "Total Harmonic Distortions" he is not qualified because recruiters search for somebody with "THD" in resume. Or, they want somebody who has "10 years experience with CentOS Linux", so a candidate with 9 years of experience of CentOS, or with 10 years, but "Red Hat Linux", is not qualified.

Don't take it out on me, blame him => wi201wbn

(unless i'm really drunk, which is pretty hard to accomplish, my left brain half refuses to communicate with the educated part)

It is your fingerprints on the gun, so you will stay in this place for a while. (my complements to the gentleman)

I don’t know if the moderators will consider your excuses
