A second gallery of mathematical cranks, wanks, and wonks


Continued from part one, this will be a second look at the many purveyors of woo in the math world. Fascinating though they are...

Radiant Primes

OK, we'll start with a gentle example. This guy... might be right, it seems to check out. But his idea of taking prime numbers, converting them to another base, reversing the digits, converting that number back, and then checking if it's composite or prime and then (are you still following?) plotting the result in dots on a graph produces a picture that's pretty much the random static noise you'd expect to get with some radial lines raining down. He explains the process lucidly here. It makes a pretty cellular automata, but I don't see what he's so excited about. This isn't crank math so much as it's a fundamental failure to understand how math research works.

"God Almighty's Grand Unified Theorem" (GAGUT)

Oooooh, we have a live one! It's hard to tell if this is math though, or if the passion of this person's vision transcends the simple arts of calculus altogether. Anyway, any page written in ALLCAPS that yells "GOD!!!" this many times is a guaranteed winner. Diving deeper into the site, however, reveals a lot more ALLCAPS raving and not a hell of a lot of math. But I noticed an awful lot of focus on race (pro-black) including one link that insists God elected Obama. Then you find this:

...clicky to biggy, and you'll find the biggest equation to nutting ratio on the site, and that's just one unexplained line. Yes, I see, the capital G is God. Now what?

Truth Evolutionism

Now this guy sounds like the Time Cube guy on Prozac.
"So sciences about largest negative action pursuit, largest happiness pursuit, largest profit pursuit and largest knowledge pursuit are unified into one: Science of Pursuit"
 Right, but how does that help us get laid? I confess that this guy loses me every other sentence, so I can't so much trace reasoning flaws because I can't follow the reasoning. The guy just won't slow down and let the rest of us catch up to the monologue in his head.
"In Truth Evolutionism, every existence origins from perturbation in nihility. So its ultimate goal is to find the evolution process from perturbation to existence and the best methods for expansion."
 um?
 "Physicists have discovered least action principle, so basic natural laws are best methodology to pursue negative action. So for systems with the same mathematical expression as negative action, basic natural laws will be their best methodology."
ah...
"This is an objective truth standard. Larger system won more attention, respect and even worship from human beings. You can imagine, if there were a system larger than universe, its laws will be worshiped better than "natural laws", and treated as more important truth than natural laws. With the objective truth standard, the system with the largest possibility to be observed contains ultimate truth."
Dammit man, slow the hell DOWN! This sounds like you could cook up a philosophy here, if only you'd quit nouning verbs and dropping 'the's!

Return to Socrates



Right at the top, we start out with "Ideas, Philosophy, Science, Software, God, Universe, Randomness" - Which leads me to my own first theory of math cranks: If you're trying to tackle more than two big ideas in one paper, you're probably a crank. This guy has also been in business a long time, and makes reference to readers and even a message board for open discussion at one time. But, weird for an admirer of Socrates, his primary mathematical fixation seems to be on gambling. We're in luck, probability math happens to be one of my favorite fields. Anyway, he starts out attacking the lottery for not paying true odds. Correct so far; I think all lotteries should be burned to the ground. As soon as he starts rattling about betting systems, I set my Ctrl-F for "Martingale" and bingo!


Yep, crank. For those of you wondering, a Martingale system is one where you try to recover previous losses by doubling your bet or using some other complex betting pattern. The problem where all Martingales fail is that they fall against the casino concept of a "table limit":


That limit stops you from doubling your bet infinitely; eventually you'll lose big, and then you'll never get it back. And then right after Martingale you get the famous gambler's fallacy, stated so well by our "expert" here:
"What you need is a notebook and a pencil. Write down the last roulette spins, from the oldest one available to the most recent spin. Do not start playing until you have at least 42 spins on your piece of paper. I prefer a small notebook with 20 rule lines. Multiples of 10 or 20 make it easy to count quickly the number of roulette spins. Use the roulette report that follows as the template (rows and columns). "
...the gambler's fallacy, explained in Wikipedia, is the fallacy of believing that past trials dictate future trials; in other words, if the wheel comes up red six spins in a row, then the gambler's fallacy would have it that black is a good bet right now because "the law of averages" say that red has less of a chance coming up now. The problem here is that the roulette wheel has no memory! Neither does any other random device - the dice don't know which number's "turn" it is to come up, your coin does not know that it's "supposed to" come up heads next toss because it just tossed five tails in a row.

Still, this guy's a real card. He's got books he's sold, casinos he's gotten into fights with... He's got his racket, he's happy.

Well, that runs my bookmark list dry. Til next time, True Believers!

A gallery of mathematical cranks, wanks, and wonks

You wouldn't think that mathematics, as a field, would attract that many fringe-living crackpots - at least not as much as, say, medicine or space physics. In math, after all, either 2 plus 2 adds up to 4 or else it doesn't, and there's not much room for argument after that. But, oh, how wrong you'd be! Join me on this intellectual Tilt-A-Whirl as we explore the home pages of some extremely unhinged amateur mathematicians:

Zim Mathematics

The startling page layout is just the appetizer to Zim Olsen's theories. However, Zim doesn't really seem as out there as some, merely extremely eccentric. On the crank side, there's the ranting philosophy of how we should think of mathematics, which reads like a better-educated Time Cube manifesto. On the other hand, we have the following masterpiece:
The Lord’s Prayer in System(s) Mathematics

Our Father who art in heaven
hallowed be thy name;
(1) + - × ÷ = (0) + - × ÷ = (1+0) + - × ÷ = (1,0) + - × ÷

Thy Kingdom come, Thy will be done
on earth as it is in heaven.
(1) +, -, ×, ÷ = (0) +, -,×, ÷ = (1+0) +, -, ×, ÷ = (1,0) +, -, ×, ÷

Give us this day our daily Bread.
Y(A,B) + - × ÷ => X(1,0,Y(A,B) +, -, ×, ÷)

Forgive us for our sins,
X(1,0,Y(A,B) +, -, ×, ÷) + - × ÷ => Y(1,0))

As we forgive those who sin against us.
W(A,B,Y(1,0) + - × ÷) => W(1,0)

Lead us not into temptation
X(1,0,Y(A,B)) + - × ÷

But deliver us from evil.
X(1,0,Y(A,B) +, -, ×, ÷) + - × ÷ => Y(1,0))

For thine is the Kingdom, the Power,
and the Glory, forever and ever.
F(1,0) = ___, ___, …___
OK, anybody who can engage in such whimsy has my benefit of the doubt.

Diamond Theory

Here again, I don't think Steven Cullinane is really unhinged per se. At the very least, his geometric study is fun to play with, particularly when you find this toy. And I'm not really sure that anything he says is wrong per se. But you might find yourself asking "So what?" or more to the point, "Why is this supposed to be the central theory to explaining life, the universe, and everything?"

The Correct Value for Pi

OK, here at last is somebody I can pin to the board. This Iranian scholar can't stand it that Pi is infinite, and insists that its true value is actually 3.125, so there! Wrong sir! Thank you for being up front and not burying it under 100 pages of dense "proof."

Impossible Correspondence

Ah, we love the argumentative ones! This colorful Mad Hatter uses amusing George-Clinton-type coinages like "supraconsciousness" to insist that everybody else is wrong, dammit, especially that Albert Einstein. Go on, pick a page, any page - the "Analysis of Maths by Theosophical Reduction" argues that we only need nine digits to define the universe and then wades into the I-Ching and something called the Mayan "Tzolk'in"... uh, this:

...guaranteeing that this refugee from Klingon astrology will lose the hell out of you before you can even suss out what he's rambling about. Oh, and there's a great bit of numerology about the Quran, and a piece on market cycles and Fibonacci done with no sense of irony for Darren Arinovsky's film. And hey, there's this:
"In his stand against the ether, Einstein had argued, "we should not speak of things that can't be measured." Probably the number one reason for saying that was to insure the job of measurements. Today, the Aether not only has been experimentally shown to "exist", but the reversed, subluminal group wave Aether and the superluminal phase wave Aether could also be measured once it was defined as the existent medium."
Treasures, treasures I tell you!

C.F. Russel - Cubed

This is impossible. I take back everything I ever said about the Time Cube guy; THIS is the craziest web person with a cube-centric theory! Oh, the pages start out tame enough,

but it gets crazier...

and crazier...

and CRAZIER!!!


God, thank you, man! I made it up to page 16 before I couldn't hang on any more and blew my load! And THEN I found this dingus. Take me! Take me away to your crazy, right-angled world forever.

The Monty Hall Paradox



It's well-known amongst the oldsters of the web, but it's time to introduce it to a new generation. So: The most famous nonintuitive puzzle in probability mathematics:

You're on a game show (the problem was named after the TV game show Let's Make A Deal, hosted by Monty Hall. You have three closed doors in front of you. You're told that two of the doors have a goat behind them, while the other door has a car behind it, but you don't know ahead of time which is which.

Let's belay all the devil's advocates who say they want a goat. You want a car.

The game works like this: You pick a door. Then Monty Hall opens one of the doors you did not pick, and shows you a goat behind it (he always picks a goat door). Now there's two doors left - one you picked, and the other you didn't pick. One has a car, and one has a goat. Now you get the opportunity to switch your decision to the other door, Either that, or you stay with what you've got. After you make this decision, all doors will be opened and you get whatever is behind the door you picked.

Now, what's your best strategy to win the car? Stay or switch?

The answer is that you switch. You win 2/3rds of the time if you switch, and lose only 1/3rd of the time when you stay with your initial pick.

Wikipedia has one of the most complete entries ever explaining the problem and all of the math behind it. However, what's really interesting is the story of the problem's history.

Cognitive psychologists have tested and studied people extensively on this, and no matter how far along we go on the scientific and mathematical literacy scale, the vast majority gets this problem wrong on the first guess. World-renowned Hungarian mathematician Paul Erdos first heard of the problem and got it wrong. But the most notable hullabaloo was when high-IQ columnist Marilyn vos Savant gave her answer to the problem in her column in Parade magazine... and in the ensuing months the magazine received nearly 10,000 letters from readers arguing with it, a thousand of those from readers who held PHD degrees or better. She argued back and forth with readers for months, and classrooms across the country started testing it with their own simulations an discovered that she was right.

For those of you wanting to test this out, we have these wonderful modern computers now that are so good at this. Here's just one Monty Hall simulator that's usable online.

The puzzle has also taken on a life of its own in the media, being the subject of a Mythbusters episode, several mystery TV series, stage magicians' acts, and classroom exercises. Alas, Discovery channel hordes their shows' videos on their own channel, so all I can embed is this funky video:


Now don't stay up all night puzzling over this!

A month of Fridays brings bad luck


In a tense image only a conspiracy theorist (or Nicholas Cage fan - as if there were a difference) could love, artist George Widener captures 30 Fridays, with corresponding dates, when disasters hit. And one free day!

Amazing Playing Card Trivia


The cards directly invoke the days of the year. In a standard deck of playing cards, count ace=1, jack=11, queen=12, king=13, joker=1, and all of the other cards at face value. Without the jokers, the rest of the cards total 364. If we add in a joker (for April Fool's Day), we get 365. Add in the other joker (for Leap Day) and we get 366.

Discard the jokers and count the cards. There's 52, corresponding to the weeks in a year.

There are 12 face cards, corresponding to the 12 months of the year.

There are four suits, with 13 cards each. Each of the four seasons of the year has 13 weeks.

Within each suit, there are 13 ranks, corresponding to the months in the lunar year.

According to this source, Dmitri Mendeleev, creator of the Periodic Table of Elements, came up with the idea for the organization of the table as he laid out a tableaux of cards on a table while playing solitaire.

The only reason that the ace of spades gets a big, fancy design is because British royalty used to charge a special tax on cards, being a leisurely commodity. To show that the duty had been paid, a clerk would stamp one card in the deck. Because of the way cards were sorted and packaged, the top card just happened to be the ace of spades. Hence the expression "Duty ace".

Bonus buck: See my old open-source Flash card-shuffler here, though it's not much to look at. The link to my blog post includes an explanation and source code download for developers interested in using it for their own games.

A Turing Machine Made From Model Trains


From Turing Train Terminal. In the schematics section, they detail how the system can perform up to six binary calculations. I couldn't find a YouTube video of the beast in action, so here's a Lego Turing machine instead, set to the theme to the '80s TV series A Team by somebody with nauseating taste:

In 1966, the world's richest private citizen was Jean Paul Getty, at a mere $1.2 billion

Proof of the declining value of currency, more prosperous times for all, or of more uneven income distribution? In 1966, the Guinness World Record for richest human alive was J. Paul Getty, at a mere $1.2 billion, and his worth by the time of death only equaled $2 billion. Not only that, but the oil tycoon was the only billionaire in the US.

Even adjusting for inflation, Getty's bank account would have only been worth about $10 billion today. That's chump change compared to our list of billionaires in modern times:

  • Bill Gates $101 billion (peak worth reached in 1999)
  • Carlos Slim Helu $74 billion (peak worth reached in 2011)
  • Lakshmi Mittal $69 billion (peak worth reached in 2008)
  • Warren Buffett $66 billion (peak worth reached in 2007)
  • Mukesh Ambani $63 billion (peak worth reached in 2007)
The Forbes' list strives to include everyone with a net worth of a billion dollars or more. But even it tells a story about uneven distribution among the wealthy. The double-digits billionaires run out at #88; the total number of people on the list is 1,153.

It says odd things about our global economy that in the space of five decades, what would once be considered a fortune is barely enough to scrape by now.

The Two-Deck Turnover Trick - Try It!


Take two decks of ordinary playing cards. Keep the packs separate. Shuffle each of them. Now place both decks face down side-by-side and begin simultaneously drawing one card off each deck and revealing them.

Odds are better than 50/50 that at some point before you reach the bottom of the decks, you will eventually draw the exact same card of suit and rank from either deck at the same time.

I originally saw this in a recreational math book years ago, but I'll give the credit to this fascinating poker odds wizard, since seeing the trick on that page reminded me of it.

The Film Pi Contains Math Errors


In Darren Aronofsky's 1998 film Pi, there's a scene where Max tells the Kabbalah that he's sure that they've completed their search for a number that is 216 digits long. He tells them,

"It's just a number. I'm sure you've written down every two hundred sixteen digit number. You've translated all of them. You've intoned them all. Haven't you? But what's it gotten you? The number is nothing!"

The problem is, this is impossible. There's 9.9*(10^215) 216-digit numbers. For comparison, recorded human history IN SECONDS is only 60x60x24x6000, about 1.8*(10^11). One billion computers, spitting out one number every second night and day since the dawn of human history, would not have generated every possible 216-digit number by now.

Numerous other math goofs at the IMDB page.
