The new law passed by Congress last fall replaces the oftenvillified No Child Left Behind laws  a package passed in 2001 that made education "accountability" a constant focus and that brought increased testing, more state ratings of schools and penalties against schools that did not meet improvement standards.

Fighting Crime with Predictive Policing
27 May 2016  4:47 amToday's guest blogger, Toshi, is back again.I recently noticed that there is a Kaggle competition titled San Francisco Crime Classification which asks you to predict the category of crimes that occurred in San Franciso from 1/1/2003 to 5/13/2015 in theSFPD Crime Incident Reporting system. The goal of the competition is to predict the category of crime that occurred based on time and location.This reminded me of the movie Minority Report in which a special unit of police arrests people before they commit crimes, but that's SciFi. A more realistic approach is to deter crime by analyzing the past data to predict when and where crimes take place and deploy law enforcement resources to such hot spots. This...

Interactive model of the solar system
12 Jul 2016  8:27 amMight bookmark this for future use... an INTERACTIVE model of the SOLAR SYSTEM. Kids can see, not only the orbits of the planets, but how fast they travel. You can speed everyone up... and then Mercury looks like it's twirling around so fast it makes you dizzy  but Pluto is still just crawling along! You can zoom in and out, go backwards or forwards in time, see information about the planets, include comets, moons, etc. It's really neat!I suggest choosing the "realistic model" instead of "orrery model" and realistic sizes instead of "large" from the settings (icon for settings is on the left hand side). Often, children end up believing that all the planets are fairly close to the sun because most of the...

We subscribed to a month of IXL Math to keep him in practice, but he hates that, too. I know I shouldn’t have changed so many times, but this was our first year of homeschooling, and I was trying to please him. But I’m running out of things to try. Do you think Life of Fred might work?” You’ve tried all those math programs in one year? Many people recommend that new homeschoolers take a few months off to “detox” from the classroom setting, to relax and enjoy the freedom of making their own choices. But your son might want a few months to detox from his homeschool...

Solution to the infinite hat problem/a point/a new problem
14 Jul 2016  6:04 amIn my last postI asked the following question (I've shortened it here but its the same really.) An infinite number of people, labelled 1,2,3,... have hats on their head, RED or BLUE. They must all shout at the same time a color. They want only a finite number of people to not guess their own hat color correctly. Can they do this? YES they can manage to get all but a finite number of hats wrong. Here is what they do in their strategy meeting: 1) Define an equivalence class on infinite strings of R's and B's: x==y iff x and y differ on only a finite number of places. It is easy to show that this is an Equiv relation. We think of the string as telling us the hat colors of all the people. 2) An Equiv Rel...

A BrownPalsberg selfinterpreter for Gödel’s System T
4 Jan 2016  12:40 amIn a paper accepted at POPL 2016 Matt Brown and Jens Palsberg constructed a selfinterpreter for System $F_\omega$, a strongly normalizing typed $\lambda$calculus. This came as a bit of a surprise as it is “common knowledge” that total programming languages do not have selfinterpreters. Thinking about what they did I realized that their conditions allow a selfinterpreter for practically any total language expressive enough to encode numbers and pairs. In the PDF note accompanying this post I give such a selfinterpreter for Gödel’s System T, the weakest such calculus. It is clear from the construction that I abused the definition given by Brown and Palsberg. Their selfinterpreter has good...

Making tessellations
14 Jul 2016  1:16 pmI just received my copy of Tessalation!, a great new book written by Emily Grosvenor and beautifully illustrated by Maima Widya Adiputri, which I helped fund on Kickstarter. It’s about a girl named Tessa who goes exploring in her backyard and finds all sorts of patterns, represented as fun tessellations. I’ve already had a lot of fun reading it with my fouryearold. Most of the other math blogs in the blog tour for the book release are about early childhood math education, so I thought I’d write something in a slightly more advanced vein, exploring a bit of the underlying mathematics of making tessellations. My hope is that you’ll learn some things and also come away with ideas of new kinds of... 
The route puzzle
17 Jun 2016  6:24 pmWhile poking around some old files I came across this puzzle: (Click for a larger version.) I didn’t make it, and I have no idea where I got it from (do you know?). But in any case, wherever it comes from, I think it’s a really great puzzle. I did find the number that can make it through the diagram, but I never did completely finish proving that the solution is unique. Can you solve it? Let’s see if we can prove it together. Please don’t post the number in the comments. But please do post proofs that certain combinations of nodes are impossible. For example, you might post a proof that no triangular number can be one more than a prime; that would mean the leftmost path is impossible. 
The Recamán sequence
12 Jun 2016  9:23 pmI recently learned about a really interesting sequence of integers, called the Recamán sequence (it’s sequence A005132 in the Online Encyclopedia of Integer Sequences). It is very simple to define, but the resulting complexity shows how powerful selfreference is (for both good and evil). Here’s the definition. The first term of the sequence is , and each term differs from by . Now, if were always just more than , we would have the triangular numbers: Note how is one more than ; is more than ; is more than ; and so on. But that’s not quite how the Recamán sequence is defined. In the Recamán sequence, “wants” to be less than : it will be so if is nonnegative and has not already... 
Apollonian gaskets and Descartes’ Theorem II
10 Jun 2016  7:51 pmIn a few previous posts I wrote about “kissing sets” of four mutually tangent circles, and the fact that their signed bends satisfy Descartes’ Theorem, (Remember that the signed bend of a circle is like the curvature , except that if one circle contains the other circles inside it, we give the outer circle a negative bend.) As I explained previously, if we have the bends of three mutually tangent circles, we can compute the possible bends of a fourth circle using the formula , where is the sum of the other bends and Moreover, the two solutions for have the property that so if we have one of them we can easily “flip” to the other one. Doing these repeated “flips” results in an...

Notes from ICME13
29 Jul 2016  10:58 pmGila Hanna mentioned the carpet proof of the irrationality of [tex]\sqrt{2}[/tex]. A little digging reveals that it was due to Tennenbaum (1950s) and popularized by Conway (1990s). The original proof appeared in a book but the simple idea is described in this paper “Picturing Irrationality” by Steven Miller and David Montague in the Mathematics Magazine (2012). What is more interesting is the expanded version of their paper on arXiv called “Irrationality from the Book”. One can only infer the amount of editing and changes that took place from submission to publication. This is a quote from Guershon Harel that I am trying to piece together from memory. Some of us are constructing open neighbourhoods* but...

Freeman Dyson
24 Dec 2015  6:19 pmon how mathematics is permanent while physics is ephemeral. it’s the beauty of mathematics, as opposed to physics, that it’s forever. I published my selected papers recently in one volume, and I found out that when you publish your selected papers most of the physics is ephemeral, that you don’t want to publish stuff that was written 10 or 20 years earlier, but the mathematics is permanent. So essentially everything I’ve ever published in mathematics is there, whereas only about a quarter of what I published on physics was worth preserving. The quote is taken from a interview from 1998 via Web of Stories. Watch the video directly here. By the way, thumbsup for providing transcripts. Great site! ... 
Halmos on how to study
17 Dec 2015  11:24 pmIt’s been said before and often, but it cannot be overemphasized : study actively. Don’t just read it; fight it! Ask your own question, look for your own examples, discover your own proofs. Is the hypothesis necessary? Is the converse true? What happens in the classical special case? What about the degenerate cases? Where does the proof use the hypothesis? Paul Halmos – I want to be a Mathematician: An Automathography (1985), p.69.

Two Different ClusterPolyhedra
30 Jul 2016  4:26 amAn icosahedron is hidden from view in the center of this clusterpolyhedron. To create the cluster, each of the icosahedron’s triangles was augmented with a rhombicosidodecahedron. The resulting cluster has the overall shape of a dodecahedron. To create the next clusterpolyhedron, I started with the one above, and then augmented each of its triangular faces with icosidodecahedra. I used a program named Stella 4d: Polyhedron Navigator to create these clusterpolyhedra. This software may be bought (or tried for free) at this website.

Tools to Help You Think … At Any Age!
13 Jul 2016  10:00 pmToolboxes are handy things to have around, especially when they are filled with useful tools. A maker might include a hack saw, hammer and soldering iron in her toolbox. A musician might include a metronome, pitch pipe and recording device in his toolbox. What would you find in the toolbox of a problem solver? Many things, to be sure, but among them is likely to be an array of logical reasoning skills. Logic promotes clarity of thought in understanding ideas. As the complexity of our world increases, each of us will face a growing number of unfamiliar and challenging situations. The shift to a knowledgebased economy keeps progressing. The significant decisions we must make keep multiplying. People are... 
Smart is Not What You Think. It’s How You Think.
4 May 2016  10:00 pmThere was a time when the ability to faithfully recall information was a strong determinant of success. Now we have highlysophisticated search engines and revolutionary chatbots that speak answers to your spoken questions. What you know and think is no longer the definitive measure of being smart. What matters now and in the future is how you make use of the vast knowledge that is readily available. The modern measure of being smart is in how you think. Leverage and Extend Existing Knowledge When it comes to knowledge, success today is more about whether you can combine and extend what is already known in order to address novel situations. For example, competitive business environments shift more... 
Teach Kids How to Think and They’ll Think for Themselves
27 Mar 2016  10:00 pmAs parents we instinctively want to help our children when they struggle. Our impulse is often to just fix the problem ourselves. While this approach makes sense when children are very young, as they grow it becomes counterproductive. In rescuing our kids, we provide a quick fix but deny them opportunities to practice important skills that they will need to become independent adults. This is true in general and certainly with respect to education. As children grow, we should encourage them to develop the thinking skills that they will need in college and in their chosen careers. In what may seem like counterintuitive advice, teaching kids to think sometimes involves parents doing less, not more. Here...

a first slice
17 Jul 2016  11:05 amHere is my first simple attempt at a geometric design using sliceformstudio I'm looking forward to trying out many more.I have played around a bit with sliceforms before, using instructions from John Sharp, who has written quite a bit about using them for creating models of conic sections and surfaces, and has a nice short blog post here about their history. I learned about sliceformstudio a short while ago from mathmunch.This design was based on a simple pattern of pentagons around a decagon, to which the wondrous sliceformstudio applied some interweaving that I tweaked only slightly using the very simple interface.After printing off the generated strip file onto cardstock, 10 long strips and 10 short... 
more Chladni figures in R
24 Jun 2016  5:02 pmFollowing on from an earlier post, the Chladni images here are made using a slightly modified version of the same R script (source here), which uses cosines instead of sines. If you imagine the square of the vibrating surface to be fixed at the center (as depicted below), using cosines seems the natural choice. When modeling standing waves, cosines are used to model openended pipes, while sines are used to model fixedend strings.Playing around with cosinebased formulas led to some images that seemed very close to Chadni's own diagrams, which can be found in an appendix to his book on Google books.For a few of these I've uploaded the scripts that produced them.Chladni image 40 bSourcehere.Chladni image... 
Rascal Triangle
24 Jun 2016  8:09 amA few early iterations of something produced by a short script in R. What is it? You may see it more clearly in some of its later stages of development.Yes, it is Pascal's Triangle modulo 2  I knew you would recognize it :). The R source for generating these images is here. Like other recent posts, this is another example of using R in some simple programming exercises, pretty much completely unrelated to its intended purpose as a language for statistical computing. A wile back, there was a post about using TinkerPlots, a data management software tool for young folk, to do something similar (more detailed instructions on drawing a general Pascal Triangle in TinkerPlots can be found in this article), 
chladniesque figures in R
15 Jun 2016  8:54 pmsome Chladniesque figuresContinuing on from this post, I am playing around with some unusual R language programming activities by creating some simplified Chladni figures.Named for Ernst Chladni, these figures represent nodal patterns formed by vibrating surfaces.Traditionally, these are formed placing fine particles on a surface, like a sheet of metal that is set vibrating (a violin bow against an edge of the metal plate is one popular method). The particles settle in the areas of the surface that have the least motion  the nodes. When you achieve a resonant frequency, a characteristic pattern emerges.some more Chladniesque figuresChladii was not the first to study these, but his enlightenmentera... 
some tilings on regular grids
16 May 2016  7:33 pmThe only regular polygons that can tile the plane by themselves are equilateral triangles, squares, and regular hexagons (these are the regular tilings).In the previous post, we noticed that the regular hexagon tiling can be used as a basis for creating decorative tilings of other polygons, such as nonagons, decagons, 15gons, and so on, that include increasingly curved (but still polygonal) sixpointed stars to fill in the gaps, observing with the help of a formula form another post, that polygons that can be arranged around a regular hexagon like this have a number of sides equal to a multiple of 3.15gons on a regular hexagonal gridWe can do the same sort of thing with the regular triangle tiling,...

Using Programming to Teach Mathematics
29 Jul 2016  5:00 amIt is often argued that programmers need a solid mathematical background in order to be competent in their chosen profession. Discrete mathematics offers a great foundation for programming, don’t get me wrong, but the truth is that most programmers can get away with knowing very little in the way of mathematics. In fact, if you are afraid to give programming a go because you’re scared or intimidated by the mathematics that it may require, I have both good and bad news for you. The good news is that you don’t need to know a lot of math, so go ahead and grab that, say, Python tutorial. The bad news is that you’re on the wrong website. Jokes aside, there is a distinction between Computer Science (which is... 
Math Teachers Should Encourage Their Students to Count Using Fingers
20 Jul 2016  5:00 amNote: This is a guest post by Aditya Singhal. Remember when your parents used to scold you for using fingers for math? And we used to picture fingers in our minds while tying our hands at our backs. Resisting to use fingers was tough then. Why do we still instruct students to not use fingers when we know that we ourselves couldn’t resist using this technique? Because it’s the established convention? Visual Learning Think of it this way. As of late, the importance of using visuals in teaching has been on the rise. Schools have been adopting smart class techniques to educate students in a visual way because visuals have been proven to stick around in pupils’ minds for longer. A study even claims that the...

Hard Facts and Statistical “Facts”
29 Jun 2016  6:00 am“Trust No One” — Fox Mulder’s Password I recently had a conversation with some colleagues about Apple founder and CEO Steve Jobs death from pancreatic cancer in 2011 in which my colleagues repeated the notion that Jobs would have lived if he had not experimented with “alternative” medicine prior to his surgery for pancreatic cancer — which he described movingly in his famous commencement address to the Stanford Class of 2005. There were a number of news articles and Internet posts that claimed or implied this shortly after Jobs passed away, implying or even claiming that mainstream or “sciencebased” medicine could cure pancreatic cancer. This is highly questionable at best. In his book Creativity Inc....

Benjamin Franklin’s 13 Virtues for the Next 45 Years
9 Jul 2016  6:02 amI just turned 45 years old. Like, 2 hours ago. Some birthdays cause you more pause than others. This is one of those for me. I’m feeling like I’m at the midpoint of my life. Age 50 should be the middle, right? But I can’t help but think I’m past halfway. Will I live to be 90 years old? Looks like there’s a 2/3 chance I’m over halfway to death. According to the Society of Actuaries’ life expectancy calculator, I have only about 1/3 chance of living to age 90. I don’t know much about actuarial stuff. But I do know it’s based on averages. Which means about 2/3 of my sameaged peers will be dead in 45 years. Two out of three of us won’t be around. Goodness! What should I do with the second half of... 
Fact Family – Truth Mafia or Math Term?
26 Apr 2016  6:55 amHave you heard of a fact family? Does it make you think of the math mob? Or the truth police? Here’s what it is, really. “What the heck is a fact family?” I asked the first time I read the term. And the second, third, fourth and fifth times. “Fact families” – both the term and the families – seem to be everywhere these days. So what IS a fact family? Well, it’s a family of facts. But not parents or cousins. More like siblings. Here’s a nice one I’ve known for years: And here’s another one I’m fond of: Is that a real thing in math? The short answer is “no.” When you look it up on WolframAlpha.com, you don’t get a definition. It gives you the definition of “family.” And according to that definition,... 
Empathize with an Expert
6 Apr 2016  12:03 pmThis is the second in the unofficial #HappinessHabit Series. Often we place our experts on pedestals. Rarely do we think about an expert as a “real person.” But today’s Happiness Habit is to do just that – pick an expert in an area you want to improve, and real personize them. I’m currently working on decluttering. My bedroom likes to “grow” piles of clothes. And piles of papers. And piles of… well, piles! Find your expert. I looked to my sister as my expert. She always picks up after herself. Like immediately. She never has pile growth. Ever. I asked her, “How did you create the practice of picking up after yourself?” “I hate clutter,” she replied. Well, I hate clutter too. But my...

Homeschooling in America
22 Jul 2016  2:00 pmIf you’re one of the growing number of parents contemplating using homeschooling as an option for educating your children, there’s a lot of positive news about this learning model to help you make an informed decision. Three decades ago home schooling was illegal in 30 states, but now, it’s become recognized as an achievement springboard that continues to offer value added learning advantages that traditional education has been unable to deliver consistently. Furthermore, online learning tools are leveling the playing field and even providing advantages that were once only within the domain of the wealthy.
