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!

Paul the Psychic Octopus

From 2008 to 2010, a pet octopus named "Paul" was given the rather burdensome chore of predicting the outcome of World Cup soccer matches. His handlers would put food into two boxes at a time, each box decorated with the flag of their respective country's teams, then whichever one Paul decided to chow down on first would be the predicted winner. Over his two-year career, Paul got it right 11 out of 13 times.

Of course, nobody's really suggesting that Paul was following soccer games. Rather, plain old luck doesn't put the odds too far away - one might get the same sort of record flipping a coin. Some have speculated that Paul was attracted to flags with horizontal stripes, which just raises the question of why countries with horizontally-striped flags should win soccer matches more often.

Paul was the subject of international fame - for an octopus, anyway - and was widely missed after his passing at old age of octopus years. And just when this story couldn't get any sillier, there's conspiracy theories around his passing.

Here's Paul in action during one of his televised picks:

Paul and his handler also got death threats and recipe suggestions after Paul's predictions proved accurate:
OK, now that's silly enough!

Get hit by lightning seven times; kill yourself at age 71 by gunshot

Roy Sullivan got into the Guinness Book of World Records as having been struck by lightning seven times - and survived them all! This was seven separate incidents, mind you, over a period of years from 1942 to 1977. He also claimed an eighth strike which happened to him as a child, but never bothered to record it.

Perhaps bothered too much by the way God seemed to have it in for him, he committed suicide by gunshot at age 71. His experience, however, form an important contribution to the specialized medical field of Keraunopathy - the study of the effects of lightning strikes on the human body.

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!

We're all descended from ancient Egyptians




A genealogy researcher has come to the startling conclusion that humans - all 7 billion+ of us - come from one big family tree, and furthermore that its roots are located in Egypt.

In "Common Ancestors of all Humans", Humphrys makes a strenuous case that we're all a lot more interrelated than we thought. It isn't even anything remarkable to say that we're all related - this has been claimed by anthropologists before. But this site goes the step further and concludes that the Ancient Egyptian Pharaoh Khufu, circa early 2500 B.C., is the great grand-daddy of us all.

One of the effects that goes into this is the phenomenon of pedigree collapse. This states that if you must insist that none of your ancestors were related, then you have a binary family tree that can only go back 30 generations before maxing out at a billion people - greater than the population of the world at the time! Thus, it is logical to conclude that in a world where the human population is always increasing, we would necessarily have had to have gotten those offspring from a smaller pool of ancestors.

This quote from the Wiki sums up the situation nicely:


"Small, isolated populations such as those of remote islands represent extreme examples of pedigree collapse, but the common historical tendency to marry those within walking distance, due to the relative immobility of the population before modern transport, meant that most marriage partners were at least distantly related. Even in America around the 19th century, the tendency of immigrants to marry among their ethnic, language or cultural group produced many cousin marriages."
If you're not already feeling a little queasy from the incestuous implications, consider that most religions have a creation myth involving an Adam and Eve figure, so they've been going around saying as much for years.

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.
