The Moral Hazard of Avoiding Complexity Assumptions
8 Feb 2016  1:56 pmMoshe Vardi's CACM editor letter The Moral Hazard of ComplexityTheoretic Assumptions practically begs a response from this blog. I also encourage you to read the discussion between Moshe and Piotr Indyk and a twitter discussion between Moshe and Ryan Williams. I take issue mostly with the title of Vardi's letter. Unfortunately we don't have the tools to prove strong unconditional lower bounds on solving problems. In computational complexity we rely on hardness assumptions, like P â‰ NP, to show that various problems are difficult to solve. Some of these assumptions, like the strong exponentialtime hypothesis, the Unique Games Conjecture, the circuits lower bounds needed for full derandomization, are... 
Go Google Go
4 Feb 2016  4:20 amIn 2009 I posted about a surprising new approach that moved computer Go from programs that lose to beginners to where it could beat good amateurs. That approach, now called Monte Carlo Tree Search, involves evaluating a position using random game play and doing a boundeddepth tree search to maximize the evaluation. Google last week announced AlphaGo, a program that uses ML techniques to optimize MCTS. This program beat the European Go champion five games to none, a huge advance over beating amateurs. In March AlphaGo will play the world Go champion, Lee Sedol, in a five game match. The world will follow the match closely (on YouTube naturally). For now we should keep our expectations in check, Deep Blue... 
Math questions that come out of the Iowa Caucus

The only exception is Jeb! who we call Jeb to dist from his brother. Also, I think he wants to play down his relation to his brother. Not that it will matter. Cruz/Trump/Rubio will get 8,7,6 delegates.(This might change but not by a lot). I'd call that a tie. Later states will be winnertakeall which make no sense in a race with this many people (though it may go down soon... 
We Still Can't Beat Relativization
28 Jan 2016  5:30 amAs we celebrate our successes in computational complexity here's a sobering fact: We have had no new nonrelativizing techniques in the last 25 years. A little background: In 1975, a few years after Cook established the P v NP problem, Baker, Gill and Solovay created two sets A and B such that every NP machine that could ask questions about A could be simulated by a P machine that could ask questions to A and there is some language accepted by an NP machine that could ask questions to B that cannot be solved by a P machine that could ask questions to B. In other words PA = NPA but PB â‰ NPB. All the known proof techniques at the time relativized, i.e., if you proved two classes were the same or... 
When do we stop giving the original reference?
24 Jan 2016  6:05 pmI was preparing a talk which included my result that there is a sane reduction 4COL \le 3COL (the paper is here) when I realized that if I am going to claim the reduction is by Gasarch then I should find out and credit the person who proved 3COL NPcomplete (I assume that the result 3COL \le 4COL is too trivial to have an author). I could not find the ref on the web (I am sure that one can find it on the web, but a cursory glance did not yield it). The reference was not in Goldreich's complexity book, nor the CLR Algorithms book. I suspect its not in most recent books. The reference is Stockmeyer, SIGACT NEWS 1973, Few modern paper references Cook or Levin's original papers for the CookLevin...

A Rubikâ€™s Cube Out of Dice
3 Feb 2016  8:00 amIn the past few months, I’ve been struggling to find a new hobby. While I still love hitting the links AND Zachary has expressed great interested in playing golf with me as well, it is an expensive hobby. Plus, until Daylight Savings Time rolls around and it warms up again, it’s just not going to happen. So, I’m going to try out my maker abilities and build a working Rubik’s cube out of dice and magnets. Not long ago, I watched a YouTube video of an unboxing. RedKB was demonstrating a magnetic dice cube and I was fascinated. While I could just run out and order one off of Amazon, I thought, “Why not make one myself?” So, that’s what I plan on doing. The good news is the Internet is replete with...

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. â€śWhatever 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.â€ť 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?... 
Itâ€™s okay to feel inferior
2 Jul 2015  7:35 amFind value in being the wall, when alone, you are only a brick Not all posts on this site will have to do with math, teaching, or technology. Â For example, today, during my time alone with God, I was impressed to record the following in my journal. Â It may not be exceedingly profound, but I don’t want to soon forget it because I am often, easily wounded when my ego takes a hit. Do not let your feelings push you to overreact when you encounter someone that excels at something you do not. For one, you must remember that your value, whether to yourself, to the world as a whole, or to your creator, does not depend on how well you fair against other individuals. You are vastly more complicated and intricate...



The Math Less Traveled

Post without words #5, explained
7 Feb 2016  6:32 amIf you stared for a while at the images in my previous post, you probably noticed some patterns, and maybe you even figured out some sort of rule or algorithm behind them. Commenter Yammatak expressed it as â€śYou split it into 4 and put 2 copies of the original on the bottom with the colors inverted and 2 copies on the top but rotated 90 in opposite directions.â€ť Like this: Yammatak is right: iterating this process does generate exactly the images in my post. As I noted in my response to Yammatakâ€™s comment, however, this is not how I made the images! I only noticed that they could be described using this simple rule after making them. So, how did I make them? First, I started with the...

The chocolate bar game: variants
31 Jan 2016  11:23 pmRemember the chocolate bar game? Today I want to talk about some variants. Recall that the losing positions for the chocolate bar game can be visualized like this: What if we specify that you win if you end with a piece of chocolate, instead of losing? Well, that game can be visualized like this: As you can see, it actually has a lot of the same structure, but itâ€™s as though some rows and columns got shuffled around. Can you explain this? And hereâ€™s what happens if we keep the rules of the original chocolate bar game, but arbitrarily declare that is also a losing position (though not ).

24 Jan 2016  5:51 pmIâ€™m a bit late to the party, but the Great Internet Mersenne Prime Search has recently announced a newly verified prime number, , with a whopping 22,338,618 decimal digits! This is now the largest known prime number (though of course there are infinitely many larger ones). For some perspective, the King James Version of the bible has only just over 3 million letters, oneseventh as many as the number of digits in the new prime. For more perspective on how big this number is, check out this Numberphile video, in which Matt Parker actually gets the whole thing printed outâ€¦ in 3 volumesâ€¦ with a really tiny font! Apparently a computer found the prime on my sonâ€™s fourth birthday, September 17, 2015, but... 
The chocolate bar game: losing positions proved
23 Jan 2016  3:26 pmIn my last post I claimed that the losing positions for the chocolate bar game are precisely those of the form (or the reverse), that is, in binary, positions where one coordinate is the same as the other with any number of bits appended. So things like , , , , and so on. Letâ€™s prove it! First, some notation: letâ€™s denote a length string of bits by . (There wonâ€™t be any exponentiation in this post so there shouldnâ€™t be any confusion.) Note that denotes the empty sequence of bits. Also, if and are sequences of bits, we will write to denote their concatenation, that is, the sequence of bits followed by the sequence of bits . For example, if and , then . (Again, we wonâ€™t be doing any...

Satyendra Bose
11 Feb 2016  12:30 amAs I mentioned in this blog here, a few months ago I contributed some articles to a book called 30Second Einstein, which will be published by Ivy Press in the not too distant future. One of the articles I wrote for the book was on Indian mathematical physicist Satyendra Bose. It is after Bose that ‘bosons’ are named (as in ‘the Higgs boson’), and also terms like ‘BoseEinstein statistics’ and ‘BoseEinstein condensate’. So, who was Satyendra Bose, and why is his name attached to these things? Satyendra Bose was an Indian mathematical physicist after whom the ‘boson’ and BoseEinstein statistics are named Satyendra Bose was born in Calcutta, India, in 1894. He studied applied mathematics at Presidency...

Demonstrating Understanding in Mathematics
18 Nov 2015  10:00 pmLast week, The Atlantic published an excellent article questioning the trend toward requiring convoluted explanations of mathematical thinking in Common Corealigned math classes. The authors rightly pointed out that verbal explanations are hardly the only way of determining whether a student understands a concept and that many of the brightest mathematical minds are verbally challenged. The theory that if you cannot explain, you do not understand does logically lead to the conclusion that if you understand, you can explain. (IMACS Mathematical Logic students will recognize this as an example of contrapositive inference.) That theory, however, is completely false, yet it continues to drive the misguided...

the triangle of triangles
26 Jan 2016  6:35 pmIs there a triangle that contains every possible triangle? In one sense, yes there is.In "The StienerLehmus Theorem" (which appears in The Best Writing on Mathematics, 2015, edited by Mircea Pitici), John Conway and Alex Ryba introduce a clever nomogram which they call "the triangle of triangles."As the authors describe it,each point corresponds to a triple of numbers A, B, and C, that add to 180, and so to a shape of a triangle. In the figure, A is constant on downward sloping lines, B on upward sloping ones, and C on horizontals.In the diagram below, the point P provides us with a triple (36, 60, 84), which corresponds to the shape of a triangle ABC with those angles. Note that A and B are easier to read... 
a universe of puzzles
17 Dec 2015  8:15 pmIn The Puzzle Universe: A History of Mathematics in 315 Puzzles (TPU), Ivan Moscovich stretches the concept of puzzles to encompass almost anything that combines curiosity and playfulness (playthinks is his preferred term for this more general category of puzzling items). No surprise  these playful curiosities are inherently mathematical. In an informal and accessible way, Moscovich details the development of these puzzles, revealing their surprising family resemblances and the deep mathematics behind their playful exterior.An example of a playthink that might not at first inspection resemble a puzzle in the usual sense is the spirolateral (TPU puzzle 270). Drawn following basic rules, a family of...

15 Oct 2015  6:36 pmLooking at the Kepler pentagonal tiling, it seems there is skull staring back, warning me against spending too much time playing around with polygons.But regular pentagons encourage time wasting by how they fail to fit together, forcing fusings and overlaps. For example, finding a way to build out from a central ring of ten pentagons, you might try a ring of ten fused decagons.After another jagged ring of 30 pentagons, you can add another ring made of ten rings of pentagons joined by hexagons (formed from fused pentagons).One more step, and the decagons seem to be drifitng outward  once overlapping, now with stars between them.Or, you could start with a central ring of pentagons surrounded by five stars...

Learn These Math Skills First!
10 Feb 2016  4:15 amWhich math skills does my child need to learn first? “How can he be 13 years old and not know long division? How did that happen?” That was an actual quote from a distraught parent whose child had just done “not so well” on the Diagnostic Test that Tabtor gives to all new students. It’s often the case that students struggle with a topic because they’ve either not had the chance to practice easier concepts or missed learning an easier concept entirely. So for this student, it may be that his times tables recall is weak or he’s making mistakes in subtraction or he just hasn’t learnt how to set out his log division work. Math, like reading needs to buildÂ up from strong foundations. Find out which...

Was Richard Feynman a Great Teacher?
1 Feb 2016  6:00 amBill Gates recently published a blog post The Best Teacher I Never Had with an attached video extolling the virtues of Richard Feynman, the Nobel Prize winning physicist and Caltech professor, as a teacher. Was Richard Feynman a great teacher? One of Feynman’s main claims to greatness as a teacher is the twoyear introductory course in physics that he taught to freshmen and sophomores at Caltech (the California Institute of Technology) from 1961 to 1963 that gave rise to the three volume set of red The Feynman Lectures on Physics that generations of Caltech freshman dutifully purchased each year. These are now available online. Here is James Gleick and David Goodstein in Gleick’s biography of Feynman,... 
Data Science Boot Camps
23 Oct 2015  11:23 pmBusiness Insider recently ran an article “Here’s what you should know about those 99% job placement rates at ‘coding bootcamps’â€” some of which boast $100,000 exit salaries” warning readers to be cautious about the job placement rate claims of coding bootcamps. The article noted that the Department of Education has started a pilot program for student loans for coding bootcamps, which frequently charge $1020,000 for intensive coding programs lasting a few months. This article discusses data science boot camps, a particular variety of coding bootcamp that claim to prepare students for a lucrative career in the hot new field of “data science.” What is data science?

Can Math Beat the Stock Market?
22 Sep 2015  7:13 pmIn recent years, the image of high volume Wall Street traders has started to shift. Where we once pictured highpowered, experienced professionals who worked their way up to major trading positions through sheer ruthlessness, there are now quite a few young professional types breaking into the industry with nothing but mathematical prowess. They’re being called “quants,” and their approach to trading is based on indepth statistical analysis meant to detect and act upon probabilities. In short, this thickening wave of newer, younger Wall Street heavy hitters is looking to take on the stock market with a purely mathematical approach, which gets to a question many have asked for decades: can math really solve...

11 Feb 2016  5:00 amThe kids donâ€™t realize theyâ€™re doing math, they think theyâ€™re playing a game. It keeps them motivated to keep trying because it doesnâ€™t look like math the way theyâ€™re used to seeing math. Lisa Molinaro, Principal, Woodbrook Elementary When Albemarle County Public Schools (ACPS) were searching for a technologybased software program to support its math curriculum, their primary goal was to deepen student learning. The district, nationally recognized for embracing innovative education technology, first introduced MIND Research Instituteâ€™s ST Math in 2010 as a remediation resource for the countyâ€™s Title 1 schools.

S Wave Velocity + Anaximenes and Democritus Earthquake theories
11 Feb 2016  5:32 amIn our last post, we described P Waves, their formula, and Thale’s of Miletus theory of earthquake generation. Today we are going to discuss the theories of two other famous “ancient” fellas. Anaximenes and Democritus. Anaximenes, was an Ancient Greek PreSocratic philosopher active in the latter half of the 6th century BC. One of the three Milesianphilosophers, he is identified as a younger friend or student of Anaximander (Yah! Anaximander. He has no known connection to Charmander and he didn’t evolve to AnaxiZard). Anaximenes, like others in his school of thought, practiced material monism. This tendency to identify one specific underlying reality made up of a material thing is what he is... 
Thale's earthquake theory and PWaves
8 Feb 2016  5:01 amIn June we discussed the theories in Earthquake prediction. Last week we wrote about Lame’s first parameter and Enceladus, the Mythical guy that causes earthquakes when moving underground. Despite the fact that ancient Greeks were blaming Enceladus for any earth tremors in their stories, the great minds of that era were speculating a lot about the natural causes of the earthquakes. Such theories were included in the writings of Thales of Miletus (c. 585 BCE), Anaximenes of Miletus (c. 550 BCE) and Aristotle (c. 340 BCE). Thales had the theory that earth floats on water, and Thales’s theory about the cause of earthquakes is consistent with that hypothesis . It seems that he applied his floating on water...

Long storyshort, some Giants gathered and thought that it would be a great idea, to fight the Greek Gods and take the control of Cosmos (the world). A lot of epic battles occurred in this fight, and one of the greatest is between Athena and Enceladus. Enceladus, who has NO known connection to enchiladas, was the offspring of Gaia, born from the blood that fell when Cronus castrated his father, Uranus (awwwwkwaaaard!). There is another version of the story where he was just the son of Tartartus and Gaia,...
