How to Help Our Children Be OK with Making Mistakes—and Why It’s Ultimately Worth It
28 Aug 2017  5:07 amThe idea that I might be someone who “overparents” her children came to me not while I was spending time with my children, but when I was catching up over dinner with two of my closest college friends, who are also moms. Having not seen them in over a year, we dived into conversation, but I soon found myself utterly distracted by a glass of water, perched precariously by my friend’s elbow at the edge of the table. Before even a minute could pass, I grabbed the glass and moved it to the center of the table—a move that only a friend who has known you for almost twenty years could rightfully call you out on. “Jen, if you keep doing things like that, I’ll never learn.” We all started laughing,...

Babylonian tablet with simpler trigonometry than our own
25 Aug 2017  5:45 amThis is fascinating!An ancient Babylonian tablet contains the world's oldest trigonometric table; but not only that.... it is also the only COMPLETELY ACCURATE trigonometric table, because of the very different Babylonian approach to arithmetic and geometry (using the base 60 instead of base 10).This tablet uses simpler, yet more accurate trigonometry that has clear advantages over our own modern version. It's based on ratios instead of angles and circles.It is rare that an ancient discovery could be teaching today's mathematicians something new but that seems to be the case here!I'm sure many students would welcome a simpler approach to...

How to Succeed in Math: AnswerGetting vs. ProblemSolving
21 Sep 2017  4:53 amYou want your child to succeed in math because it opens so many doors in the future. But kids have a shortterm perspective. They don’t really care about the future. They care about getting through tonight’s homework and moving on to something more interesting. So how can you help your child learn math? When kids face a difficult math problem, their attitude can make all the difference. Not so much their “I hate homework!” attitude, but their mathematical worldview. Does your child see math as answergetting? Or as problemsolving? Answergetting asks “What is the answer?”, decides whether it is right, and then goes on to the next question. Problemsolving asks “Why do you say that?” and listens...

Computational Complexity

A problem I thought was interesting now...
17 Sep 2017  9:36 pmOn Nate Silver's page he sometimes (might be once a week) has a column edited by Oliver Roeder of problems. Pretty much math problems though sometimes not quite. Some are math problems that I have seen before (e.g., hat problems). I don't bother submitting since that would just be goofy. I would be ringer. Some are math problems that I have not seen before, I try to do, I fail, but read the answer and am enlightened. I call that a win. But some are math problems that I have not seen before, I try to do, I fail, but when I see the solution its a computer simulation or something else that isn't quite as interesting as I had hoped. I describe one of those now; however, I ask if it can be made more...

The Scarecrow's math being wrong was intentional
10 Sep 2017  6:49 pmIn 2009 I had a post about Movie mistakes (see here).One of them was the Scarecrow in The Wizard of Oz after he got a Diploma (AH but not a brain) he said The sum of the square roots of any two sides of an isoscles triangle is equal to the square root of the remaining side. Oh joy! Rapture! I have a brain! I wrote that either this mistake was (1) a mistake, (2) on purpose and shows the Scarecrow really didn't gain any intelligence (or actually he was always smart, just not in math), or (3) It was Dorothy's dream so it Dorothy was not good at math. Some of the comments claimed it was (2). One of the comments said it was on the audio commentary. We now have further proof AND a longer story: In the book... 
Statistics on my dead cat policy is there a correlation?
7 Sep 2017  8:34 amWhen I teach a small (at most 40) students I often have the deadcat policy for late HW: HW is due on Tuesday. But there may be things that come up that don't quite merit a doctors note, for example your cat dying, but are legit for an extension. Rather than have me judge every case you ALL have an extension until Thursday, no questions asked. Realize of course that the hw is MORALLY due Tuesday. So if on Thursday you ask, for an extension I will deny it on the grounds that I already gave you one. So you are advised to not abuse the policy. For example, if you forget to bring your HW in on thursday I will not only NOT give the extension, but I will laugh at you. (I thought I had blogged on this policy... 
Rules and Exceptions
4 Sep 2017  7:47 amAs a mathematician nothing grates me more than the expression "The exception that proves the rule". Either we bake the exception into the rule (all primes are odd except two) or the exception in factdisproves the rule. According to Wikipedia, "the exception that proves the rule" has a legitimate meaning, a sign that says "No parking 36 PM" suggests that parking is allowed at other times. Usually though I'm seeing the expression used when one tries to make a point and wants to dismiss evidence to the contrary. The argument says that if exceptions are rare that gives even more evidence that the rule is true. As in yesterday's New York Times The illegal annexation of Crimea by Russian in 2014 might seem to...

The School of Math and Sciences has entered the world of 3D printing by acquiring a new Cartesianmodel 3D printer. The Monoprice Maker Select V2 is a hobbyist’s dream, but it also has great potential for classroom use as well as in our research programs. Thanks to a large online community of “makers,” and a particularly large user base for this particular model, the Maker Select is ideal for small projects at low cost.

How to Print to PDF on your iPhone or iPad
25 Jul 2017  2:40 pmThis howto is based on iOS 10 and I only just discovered this feature, in spite of having looked for it many times over. Whether from a website or from a word processing app or just about anywhere, I’ve always wanted to be able to print to PDF on my iOS devices. It seemed only natural that Apple would make something like this available when you print from your device. When you go to the share icon and choose to print, shouldn’t one of your options be to select a PDF printer? But, alas, you can only select an AirPrint enabled printer on your network. Well, I have GOOD NEWS! The capability is there and has been there all along. Here’s what you do: <ol> <li>Go to any app that is printenabled and select to print....</li></ol> 
Is it a core requirement or just an elective?
11 Nov 2016  6:00 amThis week of Creation Care emphasis has coincided with a very busy time of the semester on the Plainview campus. We are in the first week of early registration for the Spring term which means faculty and students alike are pouring over course schedules and degree plans. As a result, my mind has unavoidably conflated the two. As I listened to Rachel Lamb’s message in chapel on Wednesday, I was challenged in a new way regarding the role of Creation Care in my daily walk with Christ. It was several years ago when we first began our Creation Care emphasis week at Wayland that I first made the connection between caring for the environment and my duty as a Christian to be a steward of God’s creation. ... 
Why I do what I do
24 Jun 2016  4:30 amAs I glance back over the previous post where I listed out those questions I intend to tackle here, openly on my blog, I noticed a somewhat glaring omission. There are no “Why?” questions, not even the most important one: Why do I do what I do? My life has taking only a small number of twists and turns. In fact, it almost seems as though I have been on track for this current career path ever since I decided to add a mathematics major my second year of college. For those that do not know, I first shopped for colleges based on my intent to enter fulltime vocational ministry. I found Wayland to be that place where there was the greatest personal attention and interest in my own personal success. Some...

Sometimes, it’s a puzzle blog posting interesting mindbenders that need a keen intellect and occasionally, some mathematics. That’s all still here, by the way, which you can find with a notsodifficult search tool in the sidebar. It’s also been a devotional through my efforts to better understand our responsibilities as stewards of God’s creation. It’s been a log of classroom activities. At one time, I was posting periodically about what I had accomplished in each of my classes. For the last few years, it has been only a repository for sparse events and...

Faraday
26 Aug 2017  6:30 pmCompared to mathematics, physics is extremely wellfunded. For example, I have attended many talks by Nobel Laureates compared to Fields Medalists. (Locally, I have attended talks by Serre, S.T. Yau and Pierre Louis Lions. I somehow missed talks by Smale and Ngo Bao Chao. Overseas, I have heard Bhargava and Tao lecture.) But back to physics, in addition to the Nobel Lauretes, there have been many public talks on quantum mechanics, cosmology and particle physics, in relation to the LHC. The latest was on 25th August by David Gross. He mentioned that Faraday, as an answer to the question what was his discovery good for, was said to have answered “you will be able to tax it.” A quick search on the web would... 
What are the chances that a bird will poop on my car?
17 May 2017  6:30 pmThis question was posed as a scenario of mathematics in everyday life. Some googling led to Randall “XKCD” Munroe’s post here. Borrowing similar ideas leads to my own computation below. I park at an open air carpark for work. The easy assumptions are my car has a 4.3m x 1.75m footprint and I park for 8 hours a day. For data on birds, after some searching I found a 2016 article that estimates (provided I interpreted correctly) a total of 377 birds in 113 hectares of builtup area at another university in the country. So if we assume a similar bird population here and that birds poop uniformly everywhere once every hour, [tex] \frac{377}{113 \times 10,000} \times 8 \times 4.3 \times 1.75 \approx 2\% [/tex]... 
Queen of Mathematics
9 Apr 2017  5:26 pmNumber theory has been called the Queen of Mathematics. Until some fifty years ago, it did not occur to anyone that number theory, especially the study of prime numbers, would have any immediate applications to business. More recently, the Queen has been relegated to be the object of a courtship, inspired by material gains, rather than awe. As a result, progress has been made in unexpected directions, which have required deeper investigations. — Papa Paulo A.K.A. Paulo Ribenboim from his pseudonovelnumber theory text “Prime Numbers, Friedns Who Give Problems: A Trialogue with Papa Paulo” (p. 50). 
Triangular numbers modulo powers of 2 and its generalizations
14 Mar 2017  5:54 pmSomeone discussed with me an interesting problem that he was working on with his students. They found that the congruence [tex] \frac{1}{2}X(X+1) \equiv a \pmod{n} [/tex] has a solution for every [tex] 0 \le a n [/tex] if and only if [tex] n =2^k[/tex]. My first instinct of course was to complete the squares for triangular numbers and reduce the problem to [tex] X^2 \equiv a \pmod{n} [/tex]. This turn out to work well for odd modulus and the solutions for triangular numbers and squares correspond. But when the modulus was a power of 2, completing the square would not work. A simple search found a few websites where the phenomenon was recorded and it seems a (perhaps original?) source is Knuth’s the Art of... 
If there is some good inflammable stuff it will catch fire
21 Oct 2016  8:06 pmDo not try to satisfy your vanity by teaching them great many things. Awake their curiosity. It is enough to open the minds, do not overload them. Put there just a spark. If there is some good inflammable stuff it will catch fire. The quote appears at the end of chapter 14 of Polya’s Mathematical Discovery. Polya attributes the quote to Anatole France from Le jardin d’Epicure. Perhaps he translated the French into English. He further adds: There is a great temptation to paraphrase this passage: “Do not try to satisfy your vanity by teaching high school kids a lot of … just because you wish to make people believer that you understand it yourself …” Yet les us resist temptation....

Indian cosmogony
21 Sep 2017  6:30 amIndian cosmogony derive from the dimensions of Hypercube 216. The Maya pyramid is the representation of a cosmic clock related to the three dimensional experience. On a cosmic scale the number 9 symbolizes the completion of a great era of billions of years and the beginning of a higher dimensional experience. The construction of the Great Pyramid clearly shows that humanity did not evolve in a linear fashion though. The sacred scriptures of India known as the Puranas speak of the four ‘ages of the earth’ called Yugas. The sum of these four ages makes 12,000 ‘divine years’. This is clearly another ancient calendar system based on the dimensions of Hypercube 216. The Puranas tell us that ‘One...

a polynomial division calculator
15 Sep 2017  11:28 amMany visitors to this blog come to see the posts about dividing polynomials using the grid method (like this one). A while ago, I put up a page which generates examples that (hopefully) illustrate this method.Well, I am excited to say that the examples page has been enhanced with the addition of a simple calculator, which allows you to provide your own polynomials for dividing.This is not a sophisticated calculator  the polynomials you provide need to be in expanded form, and they have to be single variable polynomials using "x" for the variable  don't try to be fancy or tricky, please.For example, you may want to try something like this:After you provide your polynomials, hitting the calculate button... 
interactive chladni figure page
17 Jul 2017  7:45 pmA while back there were some posts about generating Chladni Figures using R scripts. These scripts generated some pretty nice images, I thought. But, to experiment a bit more it would be nice to have something interactive, so I put together this page, which you can use to make images like the one below.Adding more vibrations to the surface, you can get some pretty intricate looking patterns:If you would like to try it out, please visit: https://dmackinnon1.github.io/chladni/ (source here). 
truchet en plus
29 Apr 2017  1:10 pmSince the previous post, I have been playing around with more variations on Truchet tiles (using this page). The variety of appealing patterns that you can create from these simple tiles is impressive.the humble Truchet tileFor example, using this simple base tile you can create a pathlike effect, even to the extent that paths can seem to weave under and over each other. The patterns below use this effect to suggest links and knots.Truchet patters for two links (left) and a trefoil knot (right)Slight variations in the base tile can produce interesting effects. Here's an example that uses the traditional Truchet base tile.Bulging the dark right triangle into a quarter circle allows us create something that... 
truchet tiles
26 Mar 2017  2:13 pmA short while back, I posted about the images found in books about Froebelian kindergarten exercises, likeThe Paradise of Childhood (on Google Books here). These old books provide great examples of patterns and designs that can be easily drawn by hand with graph paper, in many cases only using arrangements of congruent 4590 triangles.Nineteenth Century Froebelian DoodlesA surprising variety of patterns can be formed by restricting things even further, considering the case where each square is cut in half along a diagonal with half of the square coloured black, the other coloured white (i.e. no blank or completely filled squares, as are found in the images above).Some arrangements of four Truchet... 
probability simulations using R
24 Mar 2017  12:01 pmAn ongoing side project of mine is learning how to use the statistics scripting language R, and have been putting putting together R markdown files that set up simulations for a variety of probability problems. You can find some of them here:https://dmackinnon1.github.io/r_examples/.These are simulations that generate data based on problems like the Birthday problem, the Monty Hall problem, and the Burnt Pancake problem. Learning scripting languages aside, it is always good to keep digging into probability problems: they confuse practically everyone.
