13 May 2016  12:14 pmToday I am going to talk a little about code development and appropriate hygiene that goes with it. Why?

Playing with Math Shapes
5 May 2016  9:35 amI love it when a plan — or rather, a series of math thoughts — comes together. On Monday, Emily Grosvenor (author of the Tessalation! picture book) asked me how parents who are insecure in math could help their children learn through play, and I responded with this quote from my Let’s Play Math book: If you are intimidated by numbers, you can look for patterns of shape and color. Pay attention to how they grow. Talk about what your children notice. But I wasn’t entirely satisfied with that answer. So many adults have come away from their own school experience thinking math is only numbers. Even with shapes, isn’t it the numbers about them — how many sides, what size of angles, calculate the the area or...

FAQ: Lifelong Learning for Parents
23 Apr 2016  11:52 amI’m so tired of being ignorant about math. I can memorize rules and do calculations, but if I miss a step the numbers make no sense at all, and I can’t spot what went wrong. Another struggle I have is keeping everything organized in my mind. When I learn a new concept or strategy, I easily forget it. My son is only a toddler now, but as he grows up, I don’t want to burden him with my own failures. Where should I start? As a first step, convince yourself that math is interesting enough to learn on its own merits, because parental guilt will only carry you so far.

Upfronts
19 May 2016  6:28 amThe US television industry has long fascinated me, an entertainment outlet driven by technology. David Sarnoff introduced television at the World's Fair in 1939 and developed the NBC network to provide content so people would buy RCA televisions, much the way Steve Jobs created the iTunes store to sell iPods. For decades television was broadcast over the air funded mostly by commercials. You could only watch a show when it aired and people adjusted their schedules to the broadcast schedule. People stayed home instead of going to the theater, movies, social clubs and restaurants. They all still exist but not to the extent before television. The nature of jobs changed. One funny comedian on TV would make... 
Does this leak information?
16 May 2016  11:42 amHere are four fictional stories though inspired by real world events or TV shows (I forget which is which). My question is, was a confidence broken or was some information leaked that should not have been? I do not have answers. Tenure: The candidate DOES find out the vote (e.g., 18 yes, 2 no) but DOES NOT find out who voted what. But what if the vote is 20 Yes 0 No. Then the candidate DOES know the vote. (Worse if it was 20 NO, 0 yes). I am sure this has been studied in crypto. Here is one solution: randomly flip one bit. Lawyers: CLIENT: I have roughly X dollars counting all of my assets. Are you the right firm to handle my estate? LAWYER: Yes CLIENT: Do you always say that? LAWYER: No. If you had...

Creation Care is Worship in Action
5 Nov 2015  5:20 pmI was honored to be asked to write one of the devotionals for our Creation Care emphasis at WBU this week. I thought I’d share what I wrote. “Whatever you do, work at it with all your heart, as working for the Lord, not for human masters, since you know that you will receive an inheritance from the Lord as a reward. It is the Lord Christ you are serving.” Colossians 3:2324 “I should take better care of my things.” Those words, as they came out of my daughter’s mouth were eerily reminiscent of my own childhood mistakes. She had destroyed another pair of earbuds and took full responsibility for their neglect. As for myself, it was me leaving a toy outside to be chewed up my beloved beagle. Later, it... 
Moving OneNote Notebook to OneDrive
17 Sep 2015  2:56 pmI was asked a great question in class today. Someone had a friend whose computer crashed and the student was worried about what would happen if that wiped out an important OneNote Notebook. That would be a catastrophe for me, if I were to completely lose either my Wayland or even Personal Notebook from OneNote. Fortunately, that’s not going to happen since I actually have both those notebooks in the cloud and are thus, synced across several devices. Even if an electromagnetic pulse (EMP) knocked out all of Plainview, my notebooks are stored safely on servers in Microsoft’s data farm. I should be careful to say it’s not impossible, just extremely improbable. So, how do you move your notebook to OneDrive?...



The Math Less Traveled

Book review: Genius at Play
13 May 2016  11:29 amBack in January I mentioned that I had been enjoying Siobhan Roberts’s new biography, Genius at Play: The Curious Mind of John Horton Conway. I finally finished it, and can now officially say that I really enjoyed it. This is not a conventional biography. It is all jumbled together, verging on streamofconsciousness—anything but chronological. In places, Roberts simply quotes Conway at length rather than trying to explain. But then again, John Conway is not a conventional human being. The biographical style fits him. Sometimes, reading a biography can be inspiring, as you read about a person who has achieved extraordinary things. Even if you could never achieve the same things, you still come away with... 
Tiny Polka Dot
10 May 2016  1:36 pmI’m really excited about Tiny Polka Dot, a Kickstarter project producing a deck of colorful, mathy cards especially for young children—along with a list of games to play with the cards. I have a fouryearold and I’m sure he is going to love them. (We already have Prime Climb, a game designed by the same folks, and he loves that too.) With one week to go in the campaign, they are still about $3,000 short of their funding goal—go support them if you haven’t already! If you don’t support this campaign it doesn’t get funded my son doesn’t get a deck of cards my son is sad. Don’t be that jerk who makes a 4yearold sad. Support the campaign today! 
Apollonian gaskets and Descartes’ Theorem
4 May 2016  1:44 pmIn my previous post, I explained a recursive procedure for drawing Apollonian gaskets. Given any three mutually tangent circles, there are exactly two other circles which are mutually tangent to all three (forming what we called a “kissing set”). This also means that if we start with a kissing set, we can remove any one of the circles and replace it with its “alternate”—that is, the unique other circle which is also mutually tangent with the remaining three circles. Repeating this process ad infinitum generates an infinite Apollonian gasket (in practice, we can keep going until the circles get too small to draw). So far, however, I have only claimed that various things exist. But to actually draw... 
Apollonian gaskets
27 Apr 2016  11:32 amIn my last post I showed off this tantalizing picture: This pattern of infinitely nested circles is called an Apollonian gasket. Over the next post or two I’ll explain some cool math behind actually constructing them. Mostly I will state things without proof—because I don’t yet know the proofs! [Perhaps this summer I will try to spend a day tracking down literature to understand the proofs and see how hard they would be to explain. But in any case, you can still appreciate the beautiful results without understanding the proofs!] First of all, note that it’s possible to have four circles which are all mutually tangent (that is, each circle is tangent to each of the others). As mentioned before,...

Musical Modes Applied To Moon Phases
26 May 2016  12:36 amMusical Modes Applied To Moon Phases… Prompt: Phase In music theory, the Modes of the Major Scale are 7 scales made from one scale, through the process of starting on every successive note. For example, if you start on the 2nd note of the Major Scale, Mode 2 is created. Since there are 7 notes in the Major Scale, 7 Modes can be created from it. The Modes can be referred by number, but they also have Greek names such as Ionian, Dorian, Phrygian, etcetera. Each Mode has its own “mood,” determined mathematically by its “interval contents,” which means the distance of each note from the starting note. For example, the Phrygian Mode has a “flat 2” which makes it sound “darker” than most of the other Modes....

Online Summer Courses
25 May 2016  8:00 pmAre they worth the time they consume of your vacation? Summer courses aren’t the most glamorous thing because after 2 semesters of hard work, who wants to spend some of their precious time off enrolled in another course? Most people take courses that aren’t their strong suit or boring gen eds over winter/summer sessions, making the concept even more tedious. It won’t be easy to engage yourself in the material. As someone who’s barely going to graduate on time, I chose to utilize the free time to sign up for an online math class. God knows the only productive thing I’m going to be doing is bingeing as many television shows as possible (and working at a summer camp come July). Math has been the bane of my... 
Snack Time, Math Time
25 May 2016  6:26 pmI take every opportunity to explore mathematical concepts with my grandchildren and snack time is no exception. Snack time seems to be a perfect setting to discuss mathematics, I have their undivided attention and concrete objects that can be manipulated. Yesterday, I gave my grandson, Jack, a handful of grapes. Jack is 3 years old, soon to be 4. I asked him to tell me how many grapes are on his plate. The grapes were placed in a scattered configuration. He carefully pointed to each grape and counted the grapes, not repeating or neglecting any grape. (Kindergarten Common Core State Standard for Mathematics K.CC.4 and 5) He proudly reported that he had 6 grapes. The next task I gave Jack was to find all... 
Maths Exam Hell
25 May 2016  6:07 pmSo tomorrow morning (in less than 6 hours) I take my GCSE maths exam for the 3rd time. Yeah, 3rd time. I give up honestly, i have never gotten higher than a D and i’m certainly not going to get a C tomorrow. I can’t do it, i just can’t do maths. I look at the numbers and the numbers spin around the page and it takes me forever just to do a simple sum. I can’t do mental maths like most people my age, something in my brain just doesn’t let me do it. It frustrates me more than anything to be honest, no one has ever tried to help me with maths no matter how hard I tried. I’ve been told that i’m being lazy and that i’m stupid for not being able to do questions set in front of me – this coming from an actual...

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...

IMACS will award one full scholarship and one half scholarship among... 
Mathematics Education Should Include a Strong Foundation in Logic
29 Feb 2016  9:30 pmLogical thinking can be learned at a young age with engaging games and puzzles. Logic is the systematic study of reasoned argument. Why study logic? For students planning to take universitylevel math courses, which typically involve reading and writing proofs, the benefits are evident. But even for students heading in a different direction, developing strong logical reasoning skills has benefits too. Logic Supports Learning Mathematics Few would dispute that arithmetic is a fundamental base upon which the successful learning of math is built. Consequently, the development of arithmetic skills receives enormous attention in elementary school. Logic is equally fundamental to learning all other areas of... 
Going Beyond The Math Revolution
14 Feb 2016  10:00 pmMaking better thinkers for life. "[M]any of the best mathematicians in the world have never in their lives had any interest in competition math." —Keith Devlin, Professor of Mathematics, Stanford University Several of our Math Enrichment parents have asked why IMACS wasn’t mentioned in The Atlantic’s recent article entitled "The Math Revolution". Well, we’re the first to admit that we’re not sexy! To journalists, that is. Or rather what we do isn’t sexy, especially when compared to the panache of producing math competition winners. But we believe in what we do, which is more than just math. IMACS prepares children to be better thinkers for life. And after twentythree years of seeing our approach...

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,... 
a tiling of regular nonagons and stars
13 May 2016  10:34 amWhen I found this nice nonagon and star tiling, I couldn't get They Might Be Giants out of my head. The underlying symmetry comes from hexagons though:The relationship described in the previous post tells us that the next regular polygon that can be put around a hexagon like this is the dodecagon (see the line k = 6):And sure enough, these dodecagons can also form a nice hexagonbased tiling, with somewhat pointier stars.The k = 6 line above gives us a whole family of polygon and star hexagonal tilings that follow the relationship n = 3m + 3 the stars don't start to appear until m = 2 
regular polygons in rings, part two
22 Apr 2016  9:33 amIn the last two posts, I was playing around with rings of polygons, relying on a formula developed inthis postfrom last summer. I realize that the explanation offered in that original post was not so great, so I am going to try and better explain what the "regular polygon ring formula" k = 2n/(n (2+2m)) means, and mention a few more interesting patterns.The first thing to notice, is that some regular polygons can be fitted together nicely in a ring where there is one edge (along the interior of the ring) between adjacent polygons, like these:And some regular polygons can be fitted together skipping over two edges along the interior, like these:However, some regular polygons cannot be put into such... 
rings of regular polygons in rings
18 Apr 2016  7:38 pmAs mentioned here and here, you can arrange regular polygons in regular rings.If n is even, then n regular ngons can be placed in a ring with each ngon centered at the vertex of a another regular ngon, where there are m = (n  4)/2 edges between adjacent edges of the adjacent ngons.For example, squares can form a ring around a square, skipping no edges, while hexagons can form a ring around a hexagon, skipping one edge along the interior of the ring between adjacent hexagons.Things look a bit more interesting for octagons and decagons, which due to the skipping of edges form a star shape.So if a regularngon can form a ring around another regular ngon, what happens if you make rings out of those (i.e.... 
tetradecagons and heptagons
14 Apr 2016  9:15 pmTaking another look atregular polygons in rings, here are some regular heptagons (7 sides) centered at the vertices of a regular tetradecagon (14 sides), and some regular tetradecagons centered at the vertices of a regular heptagon. The smaller polygons form rings where there are a fixed number of edges skipped between each pair of adjacent polygons.When placing the heptagons around the tetradecagon, there are two edges between adjacent heptagons, and when placing the tetradecagons around the heptagon, there are four edges between the adjacent tetradecagons. In general, when placing polygons in rings like these, if you can place the regularngons at the verticies of a regular kgon, having adjacent...

The Princeton Companion Is Back. Sort Of.
27 Apr 2016  7:52 amSeveral years ago (wow, it was 2008 – how time flies!), I wrote about The Princeton Companion to Mathematics. At the time I dubbed it, “the nicest math book I own”, and to this day, it has stood the test of time. What not everyone might know is that Princeton University Press recently released a second companion. Unlike the first, which focused on a wide spectrum of, mostly pure mathematics, this new tome centers on applied mathematics. Aptly named, The Princeton Companion to Applied Mathematics, it was released in late 2015 and my short and sweet take on this title is that it too is a remarkable book in its own right. Due to its hefty size (over 1,000 pages) I’m still working my way through it, but...

The Big List of Board Games that Inspire Mathematical Thinking
17 May 2016  9:00 amWhen a board game is presented as a math game, I am always eager to try it out! Unfortunately, in many cases I find the math in these games are too straightforward with cards of math problems for players to solve, or numbered spaces to count.These games are usually far from fun, only allowing kids to practice math facts or formulas. They lack the opportunity for the player to choose from different actions, strategize or even plan ahead. The math in board games doesn't have to be so straightforward! Math isnot just about numbers and formulas, and through games is one way we can experience the beauty of math all around us. There are many fun board games thatintegrate deeper mathematical thinking into...

Top 10 Ballistics equations
20 May 2016  5:03 am** Ballistics is the science of mechanics that deals with the launching, flight, behavior, and effects of projectiles, especially bullets, gravity bombs, rockets even baseballs. Here are the 10 equations you should have in mind if you are working on ballistics. 1. Escape Velocity Escape velocity is the speed at which the kinetic energy plus the gravitational potential energy of an object is zero. It is the speed needed to “break free” from a gravitational field without further propulsion. For a spherically symmetric massive body, the escape velocity at a given distance can be calculated by the mass of the massive body, and the distance from the center of gravity. ( Atmospheric friction (air drag) is... 
10 Equations a Geology student should know
13 May 2016  4:36 amSome branches of the Science of Geology, are pretty heavy in math and physics. Hydrogeology, Seismology, Geophysics and Structural Geology are some of them. Here we present you the 10 equations that a Geology Student should know and use. 1. Darcy's Law formula The most important law in Hydrogeology, by far. When your professor is willing to go easy on you in an exam, he is going Darcy's Law. It is fundamental knowledge for every geologist. It describes the flow of a fluid through a porous medium, for slow, viscous flow. The total discharge, is equal to the product of the intrinsic permeability of the medium, the crosssectional area to flow, and the total pressure drop, all divided by the viscosity,... 
Top 8 Biology Formulas
4 May 2016  4:41 amWell,Biology is the only science in which multiplication is the same thing as division. Although, that principle doesn't apply on Biology equations. Let’s have a look at the 8 most important of them. 1.Airway resistance Airway resistance is a concept in respiratory physiology that describes the resistance of the respiratory tract to airflow during inspiration and expiration. Airway resistance can be measured using body plethysmography. Simple (?) as that. 2.Alpha helix (rotational angle) The alpha helix (αhelix) is a common secondary structure of proteins and is a righthandcoiled or spiral conformation (helix). Residues in αhelices typically adopt backbone (φ, ψ) dihedral angles around (60,... 
Top 10 Thermodynamics formulas
25 Apr 2016  7:01 amThermodynamics! An awesome field, with many important equations. We gathered the top 10 of these formulas, just for you! 1. Thermal Conductivity – heat flow rate In physics, thermal conductivity is the property of a material to conduct heat. It is evaluated primarily in terms of Fourier’s Law for heat conduction. Heat transfer occurs at a higher rate across materials of high thermal conductivity than across materials of low thermal conductivity. Correspondingly materials of high thermal conductivity are widely used in heat sink applications and materials of low thermal conductivity are used as thermal insulation. 2. Sensible Heat Sensible heat is heat exchanged by a body or thermodynamic system... 
Top 8 Geography Formulas
21 Apr 2016  5:03 amYup, you read correct. Geography has formulas and some of them are really awesome! 1. Clairaut’s theorem Clairaut’s theorem is a general mathematical law applying to spheroids of revolution. The formula can be used to relate the gravity at any point on the Earth’s surface to the position of that point, allowing the ellipticity of the Earth to be calculated from measurements of gravity at different latitudes. Clairaut’s formula is giving the acceleration due to gravity g on the surface of a spheroid at latitude φ. Apart from geography It is also used a lot in astrodynamics. 2. Geocentric radius of the Earth Geodetic latitude is the angle between the normal and the equatorial plane....
