<br />
Just some fun background information.

<br />
So onto my musings. I started to wonder about what children might learn from counting. I'm not talking about learning their numbers or learning how to count "properly", but maybe some underlying things we don't normally think of.<br />
<br />
(Jacqui's Disclaimer: Please keep in mind that this is personal opinion when I talk about counting or what we might learn from it. I'm relying on my memories (new and old) of children counting and have not done any research to back-up my ideas.)<br />
<br />
Counting is first about putting things in order - defining a path with steps set out at regular intervals. Think about it. We learn to count by repeating the steps - one, two, three, and so on. As the numbers get bigger (somewhere above 10), children have a harder time getting the in between steps, but the general pattern remains. Think about it - children will quite often count to ten and then hit a few more numbers and go to twenty. The counting will go something like, "1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 13, 17, 18, 20." Some steps are skipped but the order from smaller to larger is maintained.<br />
<br />
So somewhere in counting, it appears that children either learn or have a built in understanding of counting as an orderly function from smallest to largest.
As children get older, they learn other ways to count. The may count by two's or three's or, once fractions are learned, by halves usually. Order and regular intervals are maintained. Most children when counting by fractions seem to know to count as "1/2, 1, 1-1/2, 2, 2-1/2" and so forth. I can't remember hearing a child count by skipping around on the intervals with something like, "1/2, 1, 1-3/4, 2, 3" and so on unless they were purposely being silly.<br />
<br />
Counting backwards also seems to maintain order and regular intervals although the path is reversed from largest to smallest.<br />
<br />
So counting might teach children about order, about following a path, about assigning intervals between things. But what happens when numbers go from counting words with no particular concept tied to the individual numbers?<br />
<br />
Once children learn to associate a concept with a number, what do they learn? At some point, children understand that a pile of 3 candies is smaller than a pile of 4 similar candies and can order piles of similar candies, but if the piles are made up of vastly different sized sweets (think a pile of 3 M&Ms and a pile of 2 chocolate chip cookies), the order might be decided based on the overall size of the piles rather than the number of items. But children do learn to discriminate between the two and to grasp an understanding of quantity.<br />
<br />
Then somewhere in there they learn the concept of number. That is that two has a special meaning - its "twoness" that doesn't change whether you talking about two elephants or two pennies. This is an import thing to learn because the child has learned to think symbolically and communication is largely symbolic.<br />
<br />

J. O'Connor and E. F. Robertson begin by saying that ”Mathematics starts with counting. It is not reasonable, however, to suggest that early counting was mathematics. Only when some record of the counting was kept and, therefore, some representation of numbers occurred can mathematics be said to have started.” (MacTutor History of Mathematics, http://www-groups.dcs.st-and.ac.uk/~history/)<br /><br />On the same note, I believe that the first brick in understanding mathematical cognition is counting. Fortunately (for me) there has been a great deal of research on this subject. There is a significant amount of evidence through studies done for at least the last 30 years (as far back as I looked) that show a recognition of numerosity and counting not only in people but also in a variety of animals – birds, rats, various monkeys/apes, etc. Granted the animals do not exhibit an ability to detect numerosity much above quantities of 3 – 5, but it’s there. This leads me to believe that a basic knowledge of counting is hard-wired into our brains. It’s an evolutionary trait handed down from our ancient ancestors.<br /><br />There was a study reported on in SCIENCE in 1999 that sheds a little bit of light on how our brains are wired for counting. This is an illustration that appeared with the article.<br /><br /><a href="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiFsMnY_VL7uhMH_5oDFvm2pyZQIT5Cj5uSnhFsICL0YM75Th2ezHhAeSAomagZr58WMStQhNwT_emMJa5u9jgfSZISH28EmtxDX0Q3uBHEH7MwxCZv81YtnQ7dgM_hxEEFRgd0/s1600-h/braincounting.jpg"><img id="BLOGGER_PHOTO_ID_5074932402910535282" style="DISPLAY: block; MARGIN: 0px auto 10px; CURSOR: hand; TEXT-ALIGN: center" alt="" src="https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiFsMnY_VL7uhMH_5oDFvm2pyZQIT5Cj5uSnhFsICL0YM75Th2ezHhAeSAomagZr58WMStQhNwT_emMJa5u9jgfSZISH28EmtxDX0Q3uBHEH7MwxCZv81YtnQ7dgM_hxEEFRgd0/s320/braincounting.jpg" border="0" /></a>DIAGRAM: Figuring out arithmetic.

E., Where mathematics comes from: how the embodied mind brings mathematics into being). In both cases, language becomes the underlying explanation for mathematical cognition. Devlin posits that mathematics piggy-backed on language. Lakoff and Nunez use linguistics constructs to explain the cognitive processes underlying mathematics. <br /><br />So let's decide if mathematics is a language using a general definition of language. Language is a complex system so no simple definition will cover all the nuances, but we can for the time simplify as much as possible. A definition of language includes producing speech, analyzing the speech we hear, the vocabulary and its symbolic references we use, grammar, and syntax. (Deacon, 1998, p.40) Deacon offers a generic definition for language as “a mode of communication based upon symbolic reference (the way words refer to things) and involving combinatorial rules that comprise a system for representing synthetic logical relationships among these symbols.” Deacon also states that within this definition mathematics “might qualify as having the core attributes of language.” (Deacon, 1998, p.41) <br /><br />Let's see what the "core attributes" of language might be. You can say that language consists of basic sound units, phonemes that combine to form morphemes. These phonemes and morphemes when combined according to predefined rules become abstract symbols which we ascribe meaning to and understand. In other words, they become words. Language also allows various combinations of these symbols by following syntactic and pragmatic rules - sentences and paragraphs. (See Matlin, 2005, p.298) The result is communication that describes an object, event, or action, which need not be present or even exist. In other words, language symbolizes and creates meaning using a series of abstract symbols (letters or sounds) which have no particular connection to a concrete object other than those connections we agree exist.<br /><br />Presented in these terms, the phonemes of mathematics are the basic digits, zero through nine. These digits are combinable following a few simple rules and form mathematics morphemes, numbers such as 123 or 3.1416 or even 4/5. The branch of mathematics in question defines the particular syntax used. For example, Algebra’s syntax determines how to write an equation and the order of operations used to solve the equation. Each digit, number, or equation symbolically refers to a quantity or describes a system, event, or form. The actual quantity need not be present nor does a quantity or an equation need to refer to a concrete object or collection of objects. Many of the systems, forms, and events described by mathematics are themselves abstract concepts such as equations which describe the multidimensional shape of the universe.<br /><br />Do these similarities between language and mathematics provide a sufficient condition to call mathematics language? In some instances, mathematical and language processing take place in areas of the brain that are generally similar. Experiments done on bilingual individuals indicate that exact calculations occur in the left inferior frontal lobe of the brain. This area controls linguistic representations of exact numerical values. However, approximations of numbers occur in the left and right intraparietal sulci in areas associated with visuo-spatial tasks. (Butterworth, 1999; Dehaene, Spelke, Pinel, Stanescu, & Tsivkin, 1999)<br /><br />Given this, my answer to the question is “yes, there exists a well defined language of mathematics used to communicate mathematical knowledge.” However, I believe that it is a mistake to confuse the act of communicating mathematics with the cognitive processes taking place while doing mathematics so my answer to a mathematical language that defines the cognitive process is “no.” <br /><br />References:<br /><br />Butterworth, B.

The search started with a book recommended to me by a high school principle, lead to a research project and rather long (one hour) presentation, and then became something of an obsession. The biggest problem I’ve been having is that the bulk of the research being done on mathematical cognition looks at arithmetic but not mathematics (geometry, algebra, and so forth). I have a couple of other problems right now. The first is that the more I’ve looked at one of the few theories of mathematical cognition that addresses “higher” mathematics, the more I think they’ve got it wrong. The other problem is my lack of access to people who study the subject which means that I can come up with all kinds of ideas, but have no way to get any feedback.<br /><br />(And if I actually ever arrived at a coherent theory, I’d have no way of testing it. But I guess that’s another story.)<br /><br />The lack of feedback leads directly to all of you. I decided to pretty much write papers and put them here for your comments, questions and ability to find the holes in my logic. There are a number of areas to looks at – the evolution and development of the brain and of cognition in general, the historical development of mathematics, studies of brain “use” while doing mathematics (or arithmetic), studies of mathematical learning disabilities, and possibly the effect of changes in society.<br /><br />I’ll post the first of these “papers” in the next few days. Just to get it out of the way, I’ll talk about my ideas of whether or not mathematics is a language and whether or not mathematical cognition can be understood that way.

I like the regular student computer lab better - mostly because I'm sitting at a desk with space to spread out my stuff. The library is somewhat less "user friendly." But the librarian got my laptop connected to the college Internet, so that was pretty cool. I spent a couple of hours scanning journal articles about genetics and evolution of the brain. Obviously there weren't a lot of students needing assistance. <span class="blsp-spelling-error" id="SPELLING_ERROR_0">LOL</span><br /><br />What I really started looking at (but got a tad side tracked) was information on the calculations used to determine when in the past a mutation <span class="blsp-spelling-corrected" id="SPELLING_ERROR_1">occurred</span> in a particular gene. I did read some interesting stuff in relation to that.<br /><br />You can expect to see more about this since this is the only forum I have.Anonymoushttp://www.blogger.com/profile/14350832388608921347noreply@blogger.com1tag:blogger.com,1999:blog-17504635.post-45502187595277987012007-05-14T09:14:00.000-04:002007-05-14T09:19:11.163-04:00Math and GenesIf you start reading about genetics, you start running into a lot of mathematics. Well, you don't usually know you have, but the math is there. Articles will appear that talk about the evolution of genes (or species) and refer to work that was done to try and determine when a gene mutated. The articles seldom (never?) actually show you the math, but here's one that does from MathTrek - <a href="http://blog.sciencenews.org/mathtrek/2007/05/a_grove_of_evolutionary_trees.html">A Grove of Evolutionary Trees</a>.Anonymoushttp://www.blogger.com/profile/14350832388608921347noreply@blogger.com2tag:blogger.com,1999:blog-17504635.post-90923543012495355562007-05-14T08:49:00.000-04:002007-05-14T08:57:49.260-04:00What are you doing on your summer vacation?I'm moving, looking for a permanent job, and working!!!!!!!!!!!! I start a summer stint (30 hours/week for 12 weeks) in the college's student computer lab. Because of the nature of the job, there's a lot of down time so I will be making a concerted effort to read and understand H. M. Edwards' book <a href="http://www.amazon.com/Riemanns-Zeta-Function-Harold-Edwards/dp/0486417409/ref=sr_1_1/002-6106734-9838444?ie=UTF8&s=books&qid=1179147115&sr=1-1">Riemann's Zeta Function</a>. I'm really looking forward to this.<br /><br />I'm not, however, looking forward to getting everything sorted out and moved. I hope that getting my <span class="blsp-spelling-error" id="SPELLING_ERROR_0">internet</span> connection moved goes easily.<br /><br />So what marvelous plans do you all have?Anonymoushttp://www.blogger.com/profile/14350832388608921347noreply@blogger.com0tag:blogger.com,1999:blog-17504635.post-46522509612514368582007-05-07T09:52:00.000-04:002007-05-07T10:02:59.923-04:00Still looking for a jobSometimes I wonder if I shouldn't just give it up and apply for well fare. <br /><br />I was contacted by a company and went through two telephone interviews - one with HR, one with the relevant manager. Then they brought me in for four face-to-face interviews - HR again and three managers. But did I get the job? Nooooooooooooo. According to the email I received (almost a week later than they told me I would hear and after contacting them), I was an excellent candidate, but they hired some one with some unique skills (translation - younger than me).<br /><br />The supervisor for the college computer lab contacted me to see if I wanted to work there for the summer (no students available for the work). So that's what I'll be doing for 12 weeks. Not a lot of money, but the basic bills starting in June will be covered.<br /><br />The worst part of all this is that my lack of income means I'm losing my house. I'm trying to see if I can stave it off long enough to try and sell the house myself, but it's not looking good.

This morning's search hasn't been particularly productive, but HotJobs has the following listing. This is a job that I would absolutely love to have, but there is no way in the world I can even pretend to be qualified. Although it's pretty scary that I know what the ad is talking about. LOL <br /><br />So here's the ad. Doesn't this sound like way too much fun?<br /><br />Computational Research Scientist (Biomedical)<br />Company Name: Delta Search Labs, Inc.<br />Job Category: Pharmaceutical/Biotech; Technology<br />Location: Cambridge, MA<br />Position Type: Full-Time, Employee<br />Salary: Unspecified<br />Experience: 2-5 Years Experience<br />Desired Education Level: PhD<br />Date Posted: April 10, 2007<br /><br />Solutions Labs (<a onclick="newJobClick(null)" href="http://hotjobs.yahoo.com/jobseeker/jobsearch/linkoff_newwin.html;_ylt=Am7IgHlEkciXL9QsW87u.s6mRKIX?jid=JZW78G3HQOT&lo=http%3A%2F%2Fus.rd.yahoo.com%2Fhotjobs%2Flinkoff%2Fjob_detail%2F506586%2FJZW78G3HQOT%2Fevt%3D21110%2FSIG%3D11844al3i%2F%2A%2Ahttp%253A%252F%252Fwww.solutionslabs.com%252F" target="_new" rel="nofollow">www.solutionslabs.com</a> ) a Cambridge MA based R&D company, is recruiting one or two candidates with the following qualifications. Ph.D. or M.S. level researcher (M.S. absolutely must have several years relevant experience) with degree in Computer Science, Chemistry, Biophysics, Physics, Molecular Biology or Chemical Engineering wanted for bioinformatics, chemoinformatics, and chemometrics algorithm development. Will also consider exceptional candidates from Applied Mathematics, Statistics or related Engineering fields. Documented accomplishments in computational research and strong analytical, statistical, and numerical analysis skills required. Experience in spectroscopic data analysis (NMR is especially desirable) and mass spectrometry data analysis is prefered. We are seeking individuals whose primary background is computational and mathematical but who have experience analyzing experimental data and understand problems of preprocessing chemical data from various analytic methods. Desired background includes some of the following: pattern recognition, machine learning, multivariate statistics, numerical analysis, etc. Sufficient knowledge of biochemistry and molecular biology to interpret results of data analysis within a systems biology context (e.g. metabolic pathway analysis) would be a big plus. Experience with analysis and interpretation of Affymetrix microarray studies is also a big plus. Initial projects will be for both small molecule spectroscopic data pattern recognition (metabolomics) and DNA microarray analysis but might eventually expand to include mass spec proteomics. Position will involve both algorithm development and extensive programming. Programming may be done in Matlab and other scripting languages (e.g. Python). Position could involve collaboration with leading academic research groups. Ideal candidate will be creative with the desire and ability to help identify and aggressively pursue new opportunities in emerging fields. Strong written and verbal communication skills are a must. Prefer either US citizens, US permanent residents, or NAFTA TN applicants (but not an absolute requirement for exceptional candidates).
