Only after that (really, after western mathematicians accomplished the same thing as al-Kashi) did decimals begin to displace sexagesimals for use in scientific computation.”<br /><br />Why base 10? Why not base 2? Or base 60? Mathematically, they are all identical. I spent too many years working with computers at a low level to ever want to use base 2. Way too many digits to deal with. We naturally use base 8 (octal) or base 16 (hexidecimal) instead. Why not base 60 instead? My guess is that it is too hard to learn the symbols, and almost impossible to learn the addition, subtraction, multiplication, etc tables. I suspect that if we hadn’t picked base 10, because we have 10 fingers to count on, base 8 would have been the choice. Almost as much information per digit, and math tables are only 2/3 the size of base 10 systems, while base 16 tables would be roughly 2 1/2 times as big.

The children of Seattle are being taught to hate and despise and blame white people for all the things wrong in their life.<br /><br />It's every bit in the same spirit as the hatred the German Nazis directed towards the Jews.<br /><br />Maybe I need a better name, maybe I need a different word to describe it, but still I'm not lying or spreading falsehoods when I say that Seattle employs one heck of a lot of people who are the equivalent of Nazis and that in this respect the Seattle school system is malignant and evil.<br /><br />Moving on from that and please don't pretend that what is going in Seattle is meant to do good, my belief is that the primary value of teaching math is that people discover a new way to think, and that this different way of thinking is about far more than just doing math. I don't think everyone gets it, and it is entirely possible to pass math courses without ever learning to think mathematically, but some percentage do get it, and once they get it, it will ripple out and open up and change all of their thinking.<br /><br />Finally let's not lie about our past. The greater proportion of what we call math was invented by Caucasians, or at least as far as we know. That's an important qualification.<br />We know that that mathematical thinking happened in early India, but the manuscripts that survive are quite limited.<br /><br />The foundations of math, arithmetic, are old and deep and I think every culture that has had a written language has also had some kind of arithmetic. As with written language, we know that arithmetic was independently invented at least twice, in the Americas and in what we today call the Middle East. But it's possible that it was independently invented in China, and the only reason for doubting that is that there was a chain of people connecting the two areas. And it is also possible that it was independently invented many times.<br /><br />Likewise we know or believe that an early form of algebra was invented in some part of what we today call India (or maybe it was Pakistan) and we know that Muslim scholars in the Middle East added to it.<br /><br />But if you look at all the ideas that we describe as algebra today, 99% of it came from Caucasians. Or at least that would have been true if this were the 1950s. But things change fast, and math is not a stagnant field and new discoveries are being made all the time. And there are mathematicians all over the world now and that means that the new discoveries are going to come pretty much from everywhere.mandrewahttps://www.blogger.com/profile/16145017410900677001noreply@blogger.comtag:blogger.com,1999:blog-6329595.post-10560154869411048642019-10-11T21:00:06.520-05:002019-10-11T21:00:06.520-05:00Wait until the woke crowd hear about imaginary num...Wait until the woke crowd hear about imaginary numbers.Original Mikehttps://www.blogger.com/profile/01714345479248980398noreply@blogger.comtag:blogger.com,1999:blog-6329595.post-31230738576658514222019-10-11T20:23:09.056-05:002019-10-11T20:23:09.056-05:00I wasn't talented at math but I dragged myself...I wasn't talented at math but I dragged myself through a year of calculus, then graduate statistics and computer modeling.

Post-Modernism can be very useful that way.<br /><br />Ideologies exist not only the minds of the true believers who can articulate their premises, but also as the foundational assumptions that guide the day to day life of ordinary people. Post-modernism has been around for a long time, and it's had time to move outside of academia into the broader life-world. <br /><br />Without a knowledge of Post-Modernism, it is impossible to understand the ideology that drives the modern Western Left. The Right tends to think it's some form of Marxism, but it's way past Marxism, and many of its assumptions are actually contrary to orthodox Marxism.

But if you've only spent $1500 by October, you probably aren't going to spend even $3000 this year, unless you do a lot of Christmas shopping at CostCo. <br /><br />True, however, I was responding to the idea that if I increased my fees by 100%, in order to get all the money back by the end if the "MEMBERSHIP YEAR" which began in June of 2019 and ends in May 2020 I would have to spend a total of $6000 to recoup $120 by next May.<br /><br />June, July, August, Sept....that is 3 months of a Membership year; in which we had already spent a little over $1500....not including the $380 we just spent. <br /><br />I would then next year (June to May) also need to spend $6000 for a measly 2% return to get my investment back. Not a good deal, especially when the rest of the fabulous benefits are something that I won't use or not likely to want. Not a totally bad deal but why sink and extra $60 bucks that I am not going to get back.<br /><br />If they were offering me 2% on my existing fee of $60...maybe a deal and easily will easily break even at the end of the MEMBERSHIP year. <br /><br />But that isn't their aim. They just want to increase their fee income by 100% and also get suckers (I mean customers) to step up their spending.

Perhaps they'll have more examples of how to use math to solve problems more "real world" than calculating the progress of that poor guy rowing against the current. (I spent my school years wondering why he didn't row with the current.) <br /><br />We can tell students that it's OK for black people to do math because math isn't "white." (Where I live, in California, white kids think math is Asian.) But I think it's more useful to explain that learning to do math is not contingent on racial or ethnic origin. Anyone, even Barbie, can learn math if they're willing to work at it. <br /><br />My husband's grandfather was a barrel maker from Calabria, the descendant of poor, uneducated peasants. His children didn't go to college, but most of their children and grandchildren (male and female) are engineers, and most of the rest are in other math-centric fields.

They think that the stamp--the degree, credential, whatever--has nothing whatever to say about what a person knows or can do other than that someone conferred upon them a stamp. The stamp is not "for" anything but the approval of the stamp-awarder.<br /><br />To most of us commenting here, if someone who knows no physics is given an physics degree, that is wrong. The stamp was awarded in error or unjustly. If someone who knows physics fulfills the requirements and is denied an physics degree, that is wrong. The stamp was withheld in error or unjustly.<br /><br />To the left, if an oppressed minority is denied the stamp for any reason, that is an injustice, it is a mechanism of oppression. Physicists are not letting someone in their club because they don't want to share.<br /><br />In other words, they think exactly as the Scarecrow did when Oz gave him a diploma or the Woodman when Oz gave him a heart. The Scarecrow thought the award of the diploma <i>made him able to think</i> and the Woodman though the heart <i>made him feel</i>. But the Scarecrow of course had been thinking and the Woodman had always had feelings.Gabrielhttps://www.blogger.com/profile/18188485747371986575noreply@blogger.com
