Randall Munroe disproves evilution


Some of you may have noticed the lack of updates here yesterday. I must apologize; I was in a crisis and having a bit of a breakdown. You see, everyone was sending me the latest xkcd comic, which was kind of like the God Equation, except that I have a deep and abiding faith in Randall Munroe, praise be unto him, amen, and knew he wouldn’t get the math wrong. At first I laughed, but then as the implications began to sink in, I realized I was in deep metaphysical trouble.

i-e8e6b1af1d01f3e0104eaa3eb289710a-dim_anal.jpeg

You see, the width of the English channel is variable: it’s going to vary by small, chance amounts as waves shift grains of sand and erode away bits of rock, and it’s going to have a larger cyclic component to its variation that correlates with the tides. Initially I figured this would simply have some kind of reciprocal relationship with Prius gas mileage, but then I noticed that it was the official EPA measurement of that parameter, which is only going to change quarterly or yearly. Which means that either a fundamental constant, the Planck energy constant, or the pressure of the earth’s core is fluctuating. Physics is in trouble. This could invalidate radiometric dating methods, and Munroe has failed to mention our other peril: if Prius gas mileage gets too high, perhaps the pressure at the Earth’s core will increase…until the planet explodes.

Then I realized that we evilutionists have claimed that the English channel has not always existed — during the last ice age, the value of the denominator in that term would have been zero. This cannot be. Either evilution or math is wrong, and since evilution is dependent on mathematics, I’m going to have to say the math can’t be wrong. And note, please: the end of the last glacial period was approximately 10,000 years ago, quite close to the approximate time of Creation as argued by some followers of the Holy Bible.

This represents a proof by division by zero error for a Young Earth.

It also means that we have to completely rethink our picture of what human life was like ten thousand years ago. All the textbooks now natter on about making baskets and flint knapping, but do any of them mention that cavemen would have also been getting phenomenal gas mileage in their hybrids?

Furthermore, the revelation that a fundamental mathematical constant like pi is the product of English geography does sort of mean that England does have divine status, and we rebellious colonists have been in a state of sin for a few centuries. It also makes Japanese industrial culture a centerpoint of the universe.

So I had to spend yesterday rebooting my philosophical premises. It took a while, but I’m now a Young Earth Otaku Tory. The blog will have to change its focus a bit; I hope you don’t mind.

    Yep, nothing like random, meaningless math equations to get things going. If you work on it, PZ, you and Randall can be as famous as Immanuel Velikovsky.

    Looking at that equation, I realize that Pi actually can be made to equal 3, either by adjusting the width of the English Channel or by fiat of the EPA. Wow.

  7. cuco3 says

    Obiously it’s absurd to think that the Planck constant could change. However, did you consider that the standard metre might not be fixed?

    Clearly this would have enormous implications for all aspects of science. One that quickly comes to mind is that it totally accounts for the supposed expansion of the universe. If the stars aren’t moving apart, but it’s simply that the metre’s been changing over the years then the ~14Gyr age of the Universe is called into doubt.

    Glad to hear you colonials have finally come to your senses. You will be so much happier under British rule once we have finished opening pubs and fish and chips shops across the continetal US. Not to mention that we will soon sort out your health reform problems once we inaugurate the North American branch of the NHS. Of course, this will require a little extra taxation. We will get back to you about the representation. Honest

    I thought you all ate Indian takeaway now.

    Not exclsuively, but Indian takeaway is indeed one more aspect of our society that we sto-, err, ‘borrowed’ from another culture. Most of it is not even traditional Indian food, but was created in the UK for western palletes.

    Don’t worry, we will make sure to open plenty of those too. You see how the Empire brings the peoples of the World together? ;P

  16. eric-mathgeek says

    Ah, but since the EPA and Prius didn’t exist when the width of the channel was 0, the right column then is effectively 0/0, which is indeterminate. So you’re safe.

    Hm, or, it’s more proper to say this equation isn’t applicable before the Prius was created. Which begs the question, what controlled the relationship before that, and how did the Prius take its place?

    This is rather Glorith-replaces-the-Time-Trapper in Giffen’s Legion of Super-Heroes… (http://en.wikipedia.org/wiki/Legion_of_Super-Heroes#.22Five_Years_Later.22)

  17. bgsmith42 says

    I see a problem here.

    Of course, at one time the English Channel did not exist. But at that time, the Prius also did not exist. So the second term of the equation is 0/0, which can be equal to any real number since any real number multiplied by zero is zero. The equation is thus true.

    However, after the Channel came into existence, but before the Prius was developed, the second term would be zero. and thus pi would also be zero. Now, we would have noticed all these circles with zero circumferences and nonzero radii, so clearly this state of affairs never truly happened. Obviously, our memories of a time before the Prius are false. Perhaps they were implanted in our brains by Xenu?

  18. Christopher Petroni says

    All right. It’s time to get pedantic.

    Otaku comes from a Japanese word for “house.” It refers to people (usually males) devoted to hobbies that keep them indoors. I don’t think someone blasting up and down the Japanese countryside in their Prius qualifies; it sounds too cool.

    Perhaps I can suggest haiburiddo kaa mania (hybrid car maniac)? It’s more accurate, despite being about ten times as awkward.

    And yes, my pale, sun-shy fingers have revealed that I am an otaku whose hobby is pedantry.

  19. Zifnab says

    Unless, of course, Pi ISN’T a constant. And that means an increase in EPA estimates of Prius gas mileage (or a decrease in earth core pressure) just means we get more pi.

    And who doesn’t love more pi?

  20. bgsmith42 says

    I get pi ~= 3.28 using the 2009 Prius, but it’s nearly 3.6 if you use the 2010 model. I’m not sure how accurate my other figures are, they were scoured from Google and Wikipedia.

    Google calculator is teh awesome:

  22. Richard Eis says

    I don’t think Casey Luskin would “get it” in any sense of the word. Math is hard. Understanding math comedy is even harder.

  23. Harry Tuttle says

    However, after the Channel came into existence, but before the Prius was developed, the second term would be zero.

    But Prius is Latin for ‘before’ and before they spoke Latin they drove chariots. Not sure what the EPA rating for a couple of ponies attached to a cart is, but its got to be greater than zero. Thus we can minimize the time of no circles to the era between the opening of the English Channel and the development of Indo-European languages (L. prius is from the PIE root -prai). OK, that’s still a couple hundred thousand years, at least, but a couple hundred thousand years in which nobody wrote anything down so we can safely ignore it.

  33. rob says

    here is the calculation with units:

    (1.956×10^9 J / 360×10^9 Pa)*(46 mpg/21 miles)

    to get the units to work, you need to convert gallons to meters cubed. everything else is S.I. there are 264.17 gallons per meter cubed, so you get:

    (1.956×10^9/360×10^9)*(46/21)*(264.17)= 3.1440

  34. Feynmaniac says

    Can you imagine a world without lawyers?

    I get pi ~= 3.28 using the 2009 Prius, but it’s nearly 3.6 if you use the 2010 model. I’m not sure how accurate my other figures are, they were scoured from Google and Wikipedia.

    Well Wikipedia says the pressure at the core is 345 ± 15 GPa. I can’t find the experimental error for Planck energy but Ep = (ħc5/G)1/2, ħ is 6.62606896(33)×10−34 J s and G is 6.67428(67)×10−11 m3 kg−1 s−2 (c is defined exactly as 299,792,458 m s−1). By finding the experimental error for the Prius mileage and the minimum distance of the English channel the total experimental error can be found. This is left as an exercise for the reader (i.e, I’m too lazy busy to do it).

    Mathematicians are often kept off juries because of a belief by lawyers that they cannot understand the legal meaning of “proof beyond a reasonable doubt”. If you want to avoid jury duty, point out that you learned about theorems and proofs in calculus. For similar reasons, lawyers are kept out of calculus classes because of a belief by mathematicians that they cannot understand the mathematical meaning of “proof”

    Then again Edwin Hubble studied law before he became an astronomer so there may be some hope for humanity after all ;-)

    Fred, given a recent conversation here where it was reported that saying things in a nasty tone makes a difference to whether they’re true or not, it seems that most people don’t understand the meaning of proof.

We may have to let you bed in on that one before we introduce you to black, red and finally white pudding (nobody knows what is in white pudding).

    If law schools refused to admit students who hadn’t taken calculus, we could improve this country a lot.

    Fun fact: In order to be admitted to a university in Austria, you need to have taken an exam (except exceptions that involve alternative exams that I don’t know much about), and this exam, which concludes certain school types, involves calculus. Integral calculus. (Well, it probably doesn’t need to, but integral calculus is taught in the last year of those school types, and differential calculus the year before.)

    No calculus, no studying the law.

    As Feynmaniac at #33 indicated, the alt text for the original image says that the pressure must increase. But the equation looks much more to me like it must decrease if pi, planck energy, and the English Channel’s width are all held constant. Am I missing something obvious here?

    Note: The following was written for the original post regarding ‘The God Equation,’ but I was at the time unable to register for comments (apparently the system doesn’t send to mail servers with dynamic IPs); here is the second try. Enjoy.

    I don’t know about this guy’s god equation, but mine is foolproof*!

    [1 + Sqrt(5)/10] x (pi) = (e) x Sqrt(2)

    The significance of this formula is simple, and, better than this Cummings fellow, my units work out exactly — all are dimensionless, just like god!!!11!eleven!

    1: One represents the number of life-sustaining planets of which we are aware — it is also the fundamental unit, and therefore its inclusion is likewise fundamental.

    5: Five represents the number of digits on a single appendage of the human body (assuming no defects or mutilation), and is thus instrumental in every aspect of human thought. We take its square root because it is indeed the root of our decimal system (though not its base; read on). (Also, fellow Discordians, the Law of Fives prevails. Fnord.)

    10: Ten is, obviously, the base of our number system, and as such it is the base of the fraction involving its root. We add this ratio to one to symbolize the addition of life to that which sustains life.

    pi: Pi is one of the fundamental constants of nature, and if its significance is lost on any readers here, then so, too, will be the significance of this formula. It is multiplied by the sum to represent the circle of life — the sum itself was the union of life with that which sustains life — and given this understanding of the sum, multiplying it by pi implies that the sum is a radius of sorts, which I have dubbed ‘the divine radius.’

    e: As with pi, if the significance of Euler’s number is lost, then no explanation here will convince, but due to the fact that it is the natural base, its appearance was expected, and lo and behold, here it is.

    Sqrt(2): Another fundamental irrational number, the square root of two is a key factor in a great many equations of math and physics. Its appearance here unites several features: it represents the secant of the angle pi/4, which heralds the equivalence of x and y (that is, the equality of female and male). The secant function itself is significant in that a secant line intersects a circle at two points — and we’re already talking about the circle of life!

    The clear implication, then, of this formula and its significance, is that there is a god, and a designer! It can be no other way!!one thousand one hundred and eleven!!

    *Note: All constants and results are taken to five significant figures, with the significance of five only being lost on Greyfaces.

    Bleurgh, Tory? Fah. You may as well declare yourself as a whig; you’d be just as in touch with the populace.

  70. yiab.pip.verisignlabs.com says

    Perhaps all of these problems can be solved by noticing that the numbers are only correct within experimental margins of error. Before there was a Prius, there were no experiments regarding its combined EPA gas mileage, thus the margin of error was infinite and so there is no difficulty with this equation.

    Basically, if we view all of the relevant quantities as being in states of quantum superposition, we can see that by refining our margins of error on quantities like the pressure at the Earth’s core, and the Prius combined EPA gas mileage, we are actually helping to reduce the quantum uncertainty regarding the value of pi, culling the collecting of histories superimposed for our current state. Essentially, while pi=0 was part of the superposition during the Post-Channel, Pre-Prius era, it no longer is.

    Take THAT, Deepak.

    #79 is correct. The “pi” in question isn’t related to the pi that is equal to circumference divided by diameter. To my recollection, from my schoolin’, that pi term is from Buckingham’s Pi Theorem. It’s just a dimensionless constant that is used to analyze models, establish similitude, and other useful stuff.
