I totally agree with you on this. People (both children and grown-ups) need to understand that math is not boring, it is recreational. This will make learning math a happy and positive experience.

I am e...Thanks for your information and thoughts... I am educating my children, not according to any set curriculum but to what they can handle. My daughter and son are very right brained individuals, but, they are also developing their left brain, because we must use them both in conjunction with one another. Using just one or the other is why our society is far from balanced... perhaps moreso than ever on this planet.<br /><br />Many people don't know, and are not told, intentionally, that all the greatest mathematicians also studied the 'occult' or mysticism, or whatever one wants to call it. Math is meaningless without creativity (or creative wonder/thought) and will never manifest into something meaningful.<br /><br />I'd like to see in schooling, various ages, POVs, and the like; whether it be parents coming in, or alternate theorists being invited at an early age and not only at collegiate level academics. Also, challenges to the prevailing thoughts (theories that are being taught as truths) should be encouraged, not shut down as they often are. <br /><br />My son is reading Bernay's "Propaganda" (which everyone should read if they want an insider's POV regarding the real workings of life among the masses) over Shakespeare because one is truly valuable to life, and the other, while interesting and is a form of writing that one might enjoy, is absolutely meaningless in terms of understanding of the world around us and how it is absolutely run. He has already read "Sacred Geometry" and now sees the world differently.<br /><br />I didn't really like Shakespeare's works and I don't believe it should be forced upon the masses as if is part of life... as an elective, sure, great, but it is not essential to the growth of the mind.<br /><br />Sorry for the long note.. I could make it much longer. :)<br /><br />Thanks, again.Dave J.http://www.blogger.com/profile/01403208198066500332noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-48354817812200237262014-03-17T17:03:11.119-07:002014-03-17T17:03:11.119-07:00Hi Sue,

He's very thorough and doesn't skip "obvious" steps like Niven's classic half-page proof linked above (although Niven's proof is not aimed at the same audience, e.g. professional mathematicians). Spivak's (treatment of the) proof was the first proof that I was able to grasp.<br /><br />Also, you should also see this (other classic) integral @ http://www.thedudeminds.net/?p=4768 (it's in french but you'll get the math parts for sure) which links nicely 22/7 and Pi.<br /><br />Cheers !The Dudehttp://www.blogger.com/profile/09582233217452159286noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-85718168160264934562014-03-14T14:41:03.321-07:002014-03-14T14:41:03.321-07:00http://projecteuclid.org/download/pdf_1/euclid.bam...http://projecteuclid.org/download/pdf_1/euclid.bams/1183510788Tim Cieplowskihttp://www.blogger.com/profile/09721346163506388968noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-33836247640899132122014-03-14T14:29:49.669-07:002014-03-14T14:29:49.669-07:00I'm honored to find out I am one of your favor...I'm honored to find out I am one of your favorite bloggers! =) You can find the proof that pi is irrational here: http://mathlesstraveled.com/post-series/ Scroll down to "Irrationality of Pi". The proof that e is irrational is actually much simpler than the proof for pi --- I hope to write about it at some point, once I get back to blogging regularly again (at the moment I'm trying to finish my PhD dissertation). It seems there are proofs of the transcendence of e and pi which are about the same level of difficulty as the proof of pi's irrationality, but I haven't looked carefully at them myself.Brenthttp://www.blogger.com/profile/14440861005012132386noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-18776619080453743742014-03-05T16:37:33.722-08:002014-03-05T16:37:33.722-08:00Thanks for the idea!

It's written in a modest way and it seems very real because it describes real kids reactions when confronted with problem or questions. It also gives the reader a sense of evolution of children "mathematical thinking" and the way this educator copes and overcomes the difficulties found in teaching some concepts. I was looking for a book that help me to prepare some learning/playful activities for my 3 years old (in Maths field) and this one was perfect, because it gives me some real information on how he may react and how I can continue my journey if he doesn't get automatically to the wanted point. I'm also re-learning Maths in a more enthusiastic way than it was introduced to me first.Boshihttp://www.blogger.com/profile/10870743300775695062noreply@blogger.comtag:blogger.com,1999:blog-5303307482158922565.post-21538719970734473632014-02-19T12:13:41.472-08:002014-02-19T12:13:41.472-08:00I did try it in a few classes last semester.
