Germs, disease, infection…

A recent strip from Dilbert that made me smile:

Having contracted viruses from both human and electronic sources lately, I know exactly where he’s coming from.
It’s worth noting that my electronic immune system worked a whole lot better than my natural one.

Times like these…

Your Quote of the Day comes from Brian Micklethwait who has a dodgy internet connection:

My internet connection is doing weird things, going on and off and on again and off again, for no apparent reason.  I fiddle about with the connections, which sometimes seems to work, but this could be coincidence.

All of which is of some small interest, but then he bangs in a line like this:

Times like these remind me of how much my life revolves around times like these not happening too often.

Brilliantly put.
Indeed, we’re all dependent on difficulties not befalling us too often, but we rarely think about it that way until they’ve well and truly befallen us.

Satan’s Arithmetic

From Frederick Schoeman of Cape Town on Friday’s Cape Times letters page:

Satan’s Arithmetic

I believe that a couple of centuries ago, two mathematicians were demonstrating their numerical skills to the French monarchy when one of them stunned his opponent and the audience by reciting an algebraic formula and claiming it to be proof that “God lives”.
Could I borrow a leaf out of that man’s book and claim that, since the graph of world population growth over the past 1700 years looks like a serpent trying to slither up a wall, Satan is alive and thriving on human lust?

I’ve been doing some extensive research into Fred’s story, but the best that I could come up with was the the story of Leonhard Euler, who was a mathematician, but was Swiss, not French, and his presentation of an algebraic formula, claiming to be the proof that God lives. This presentation was made to another individual, Denis Diderot who was French, but was better known for his philosophical musing, rather than his mathematical prowess. In addition, this presentation was made in St Petersburg in 1774, in front of the Russian Empress Catherine II, rather than any French monarch.
Wikipedia tells us:

There is a famous anecdote inspired by Euler’s arguments with secular philosophers over religion, which is set during Euler’s second stint at the St. Petersburg academy.
The French philosopher Denis Diderot was visiting Russia on Catherine the Great’s invitation. However, the Empress was alarmed that the philosopher’s arguments for atheism were influencing members of her court, and so Euler was asked to confront the Frenchman.
Diderot was later informed that a learned mathematician had produced a proof of the existence of God: he agreed to view the proof as it was presented in court. Euler appeared, advanced toward Diderot, and in a tone of perfect conviction announced, “Monsieur! (a+b)^n/n = x, donc Dieu existe, répondez!”.

This roughly translates as:

Listen mate, a plus b to the power n, over n, equals x. That means God exists.
What do you say to that then, huh? HUH?!?

Allegedly, Denis failed to provide an immediate answer. Or indeed any answer:

Diderot, to whom (says the story) all mathematics was gibberish, stood dumbstruck as peals of laughter erupted from the court. Embarrassed, he asked to leave Russia, a request that was graciously granted by the Empress.

This sudden stage fright could have been due to Euler’s sheer mathematical brilliance.
Or, conversely, it may have been caused by Diderot’s incredulity that some Swiss bloke had successfully baffled him with bullshit by spouting some maths at him and pretending that it meant something that it actually didn’t.
Why not try something similar at your local supermarket this weekend? At the Deli counter, ask for some ham. When the lady asks how much you’d like, exclaim loudly (remembering to use a tone of perfect conviction):
“Madam! a x squared, multiplied by b x, plus c, equals zero, therefore I’m off to the jams and spreads aisle. What say you to that?”.
See if she can find an immediate answer.

When she can’t, she must ask her boss’s permission to leave the country and go back to France.

Either way, there’s a whole lot more detail, including eye witness accounts, right here.

Of course, the formula didn’t prove that God exists at all, although it later proved invaluable in predicting how long one would have to wait for the next bus to the St Petersburg city centre.
Nice work, Leonhard.

So, the first of Fred’s paragraphs proven wholly misguided, yet almost slightly true, we move on to his second.
The bit about the snake.

But before that, at this point that I’d like us all to stop and consider some stuff for just a second. Firstly, put yourself in Fred’s shoes. At some moment in time, Fred actually felt that there was a connection between his 18th century algebraic French monarchy court presentation story and a graph of world population growth over the last 1700 years. Personally, I can’t see it. It’s like me taking an excerpt from a book on the dinosaurs and somehow linking it to the recent downturn in Malaysian rubber production.
But I digress. The important point here is that Fred saw this relationship.
Secondly (and still in Fred’s shoes), Fred sat down and wrote to the Cape Times about it. That is, not only did he feel that the connection was a valid one, he felt it was worth sharing – not just with his friends (although I have no idea if he put it on his Facebook wall) – but with the general population of Cape Town and surrounds.  While he was typing (or writing – who knows?) away, he still thought it was a good idea to sent it through to the letters page. When he addressed the envelope or entered the email address (ctletters@inl.co.za), he remained under the impression that the not only did his observation make complete sense, but that it was so important that 268,000 readers should be informed of it.
And then, once his thoughts arrived at the Cape Times office, at a time when sharks, rugby, racial issues, politics and cellphone masts (What? – Ed.) are at the forefront of all of our minds, Fred’s letter was one of the seven best that was received by the local rag that day.

Yes. Really.

But onto the serpent thing. I had a good luck around on the internet and the best graph I could come up with to illustrate  Fred’s serpent against a wall thing was this one:

Obviously, you can ignore the bit before 311 AD, as Fred didn’t consider that when making his serpentine comparison.
Personally, I felt that it was a bit of a stretch, but then I’m no expert on what exactly a serpent trying to slither up a wall looks like. That’s why I searched for “a serpent trying to slither up a wall” on google images.

This was the best that I could find:

Which seems to suggest that human population exploded upwards, remained almost static while traveling back and then forward again in time, before increasing almost exponentially, peaking and then dropping off to the current number. That aside, we shouldn’t overlook that fact that

…it’s gripping onto that brickwork because Satan is thriving on human lust.

A few points, if I may be so bold:

Firstly, algebra cannot prove the existence of God. Theologians might have their own reasons for why this may be, but mine is probably more simple: that he doesn’t exist and that it’s awfully difficult to prove the existence of something that doesn’t exist – algebraically or otherwise.
Secondly, unless I’m missing some big chunk of causality here, an alleged incident in a “Parisian” court chamber 200+ years ago doesn’t have any bearing on the fact that “Satan is alive and thriving on human lust”.
Thirdly, I do still quite like the idea of an algebraic duel:

Sir, you have insulted me and I demand satisfaction. Meet me at 6 o’clock tomorrow morning and bring a blackboard.
No calculators.

Fourthly, what does Fred want us to do? Not breed? Adam and Eve bred. Mary and Joseph bred (sort of). Hey, Mr and Mrs Schoeman (Snr) bred. Are these also examples of human lust upon which Satan is thriving?
Fifthly, any line graph looks a bit like a snake on a wall.
Any block graph resembles the Manhattan Skyline.
Any pie chart has the appearance of… well… a pie. Deal with it.
Sixthly, get your historical facts right if you wish to make a good impression on those reading, but remember that…
Seventhly, just because you think something, doesn’t mean it’s a good idea to write it down and send it to the Cape Times.
Lastly, just because you think something, doesn’t mean it’s a good idea to write 1300 words on it on your blog.

We warned you

Remember this - the post where we told you that the Daily Mail was horrendously inaccurate in its description of the fatal shark attack in Fishhoek back in January 2010? (If you haven’t read it yet, you really should.)

Well, they’re at it again over the latest shark attack at the same beach. And yes, I assure you that it is the same beach. This despite their highlighting of Hout Bay as being where the attack took place – note the words “Hout” and “Bay” there in the circle:

It’s an easy and understandable mistake  to make though. After all, when you type “Clovelly Beach” into Google Maps, it actually takes you immediately to Hout Bay, 25 km away from “Clovelly Beach” and on the Atlantic Seaboard, rather than to “Clovelly Beach” in Fishhoek on False Bay.

Wait. No. It doesn’t do that at all.

I guess that we should congratulate them on correctly identifying South Africa though, even though there is a big hint in the name.

Shark Spotter flags and what they mean

After yesterday’s shark attack in Fishhoek, I listened to a woman who rang into a local radio station saying that she was confused about the flag system used on the beaches of False Bay to warn of shark activity and how she had to look at the signs each time she went to the beach.
“Red doesn’t mean danger,” she complained, amply demonstrating her confusion for the listeners.

It seems that some (re)education is required.
So what exactly do the four flags used by the Shark Spotters programme mean?

Green flag: We can see that there are no sharks around.
Black flag:  We can’t see if there are any sharks around or not.
Red flag: We have recently (ie. within the last 2 hours) spotted a shark.
White flag (and SIREN SOUNDED *hint hint*): There is a shark. Leave the water immediately.

It’s not so difficult really, is it? Especially since this helpful explanation is posted on and around all the local beaches:

As it says on the signs above (and as common sense would surely dictate) – swimming in the ocean is at your own risk. But why not lessen that risk by actually listening to these guys when they tell you to get out (or not to get in)?
