Look !!!
Paris, Tuesday April 19th, 2005, they said it would be raining the whole day, would you like to have a poll on the weather today?
Good Morning Students
Some of my younger colleagues, in a quest for publicity, have emitted the strange idea that the two globes seen on the face of the Human, globes filled probably with some gel like liquid and being used by the Humans to analyse their position and orientation, that these globes would be part of a mechanism for collecting what they call “visual” information.
Regretfully my younger colleagues seem to have devoted their mathematical training courses to other occupation than Science.
Well, students, let us compensate for the shortcomings of my younger colleagues and be privileged to an introduction to applied mathematics.
The rule of thumb is that you loose one reader per figure used. I hope you are so numerous that I will be able to afford to loose a lot of student' attention.
Well, let us assume that we discover some of the trash that Humans called essays or even worse, poems.
Let us see what we could think of:
This morning I had a walk to the Seine River. The cherry trees are flowering. It is wonderful.
An image would be something containing no less than 5 millions of points, which is rather a lot even for a medium Glub.
So, there I stand and I look at a cherry tree.
When younger I thought that the vision was something continuous. Now we are told that anything that takes less than 1/10 of a second is not seen by the eye. Taking my tax money obviously takes more than one tenth of a second as I see a lot of it.
So I look at that cherry tree; Wonderful. You would even have a picture if my camera had not given up when starting the trip.
So, a cherry tree would be 5 millions points? Probably awfully wrong but we have to start somewhere otherwise the cherry flowers will have become cherry fruits before even starting thinking;
So, let us say 5 millions (which is probably spelled 5 million, but who cares?)
Incidentally I have two eyes, so I have twice 5 millions, which makes the very convenient figure of 10 million of clicks in my eyes. And this is just in one tenth of a second;
I must have been standing in front of the cherry tree for more than 100 seconds.
So apparently my information system has been able to digest something like one billion clicks on my eye cells. One billion being for strange reasons called “un milliard” in French and in some countries one billion is not at all one billion, but ten times one million. I give that additional information to confirm your first impression that it is not really worth bothering about these idiotic figures as they make no sense.
At the same time, while looking at the cherry flowers, I was patting the neighbour's dog, talking to my wife (sorry, it could be the other way around, but which way is it really, sorry, our Data Processing System being at present overloaded we cannot process your query immediately, I learned that sentence from the Web Site of the French Ministry of Finance this year)
Apparently in less time that it takes to drink a glass of wine (French of course) my brain has been processing more than a billion of clicks or bytes or whatever you care to call it. It is beginning to sound rather unlikely, so after all, that stupid question” do we see” may have some background.
Not only that, but my eyes don't se the cherry flowers from the same angle, so they have to analyse both pictures and reconcile the figures to try and make sense out of it, again the same exercise the Ministry of Finance and myself do on the tax declaration, they wondering how I can survive on such a low income and I fully agreeing with them and yet they apparently are not pleased.
Incidentally, if you were taught like me at school that we have the perception of depth thanks to the fact that we have two eyes and that they are set 7 centimetres (that's two inches) apart, just forget about it, it simply is not true. Two inches is the length of a thumb, if you want to check by yourselves I find it better to hold the thumb on my brow rather than in my eyes.
Have you ever wondered why we have two eyes?
Have you wondered why birds, who after all probably need eyes even more than we do, look at the TV program of one channel with one eye and with the other eye look at another TV programme? So please in the future do not blame birds if they look slightly confused, it is hard enough to make sense out of the information you get from one TV channel, if you do not believe me, try to listen and look at the news in the morning from the French news channel and then switch over to the BBC channel. If you can make a ten line summary that makes sense, please send your nomination form to the Nobel Committee. Mind you, you can spare the postage, they are probably busy looking at the news on the Swedish TV which has simplified the World by drawing the limits of the civilized World at the Swedish Frontier.
We have all been taught by the high level Criminal story books we read that the treacherous enemy is always stabbing you from the back, or hitting you on the back of your head with a blunt instrument (engin contordant in French), so, why I do not in any way want to hint at any criticisms of citizens devoting their life to criminal activities, I dearly wish to express my perplexity at the Creator who placed our eyes in front, where we have no enemies, and no eyes on the back, where our enemies are. The only logical conclusion you can draw from that is that the Creator sided with our enemies, what else?
I have a strange feeling that I have gone a bit astray of my subject, which was what?
The advantage of teaching at University level is that you can and are expected to ask one of these serious looking students to remind you of the subject of the day. After some years of teaching you learn to hide your intense perplexity and surprise when being informed of what you were supposed to teach today.
Having had a look at the title of this paper, it appears that we are discussing whether Humans do have the ability to see anything and that we have all agreed after some simple calculations that we cannot see anything.
To make it worse, not only are we not able to see anything as the numbers involved would assume that our brain has the size of a well fed elephant, but to compound things, we are supposed to remember everything, in spite of the fact that we have not seen it.
I can vouch as a scientific man that I have direct experience from the fact that we cannot see anything, simply ask me what was in the letters we received today and I will accurately answer “what letters?” as to remembering what I had for lunch I may work it out using an algorithm I have developed to make life easier, I always eat the same thing at the same time.
Incidentally a word of sound advice to beginners, when you see yellow “post-it” stickers here and there, I have found it refreshing to occasionally read them, it is amazing to see how little difference it finally made that you totally forget to do what was written on the “post-it”. Usually you do not need to keep post-it whose colour has turned from yellow to some grayfish hue. Post-it with messages like “call 01 67 34 78 94” usually refer to some thing you definitively did not want to do, so you can scrap them.
What was today's subject?
Whether the Humans can see?
Are you sure this was today's subject? Sounds rather daft to me.
Any fool, and I do not want you to start thinking of some of my colleagues, any fool with a bit of mathematical training can tell you that from a mathematical point of view, Humans are totally unable to analyse information gathered through optical cells. They might believe that they see, but this is another story.
It is true that Nature tried to solve the problem;
I do not want to appear to be patronizing about the way Nature solved the problem, but some shortcuts are rather obvious;
Look at the way the comics authors depict the aliens. They use pure intelligence and common sense and put the eyes were they would be the most useful, at the end of the arms. If your eyes are at the end of your arm, say at the place of you ring finger which by the way it totally useless, the eyes would be able to look everywhere and for instance you would not have to call for a very expensive plumber when you drop you earset battery in the drain, you would just direct your eyes down the tube until you see it, grab it with your eyelids and that's all, any fool can see that this is the only way to do it.
But Nature was lazy, as it had to transfer a lot of information from the eye cells to the brain, it very conveniently decided that it would place the eyes as near as possible to the brain to shorten the travel route. If you want an analogy, if you were using that kind of logic, you would select you wife on the basis of the distance between her house and yours to diminish the tediousness and time waste of courting her.
Let us assume, for the sake of absurdity, that Humans would have two eyes, each eye collecting 5 million of clicks every 1/10 of a second, that this information would be collected and transferred by some optical nerve to the brain, that the Brain would in some mysterious way be able to make sense out of this huge mountain of useless information, let us make all these preposterous assumptions, what would be the logical next step?
Obvious is it not and it puts and end to all ideas about the proposed suggestions that Humans would gather information through the eyes?
What would the Brain do with that mountain of information?
Let us say that the Brian would have some storage area somewhere, but where?
Let us assume that the Brain would have found a system to get rid of redundant and out-of-date information material, by the ears, by the tongue?
What would be the use of keeping all this information?
Let us assume that you engrave your phone number on a spaghetti, that you cook the spaghetti, that you get all your friends and colleagues (they are not the same) to cook spaghetti, you hire some trucks, you dump all the cooked spaghetti in the backyard and then you ask your wife to find the phone number?
Does that make sense?
Yes, I can hear the objection, yes I am aware that she will find it especially if it was written with lipstick, so let us assume that you ask your friend, if you have any, to find that number?
Preposterous is it not?
I can see that the clock is advancing, so I will state that this was my conclusion concerning today's lecture on the advantages and disadvantages of a linear or holistic paradigmic approach in the temperate use of iterations as a simplifier of the analysis of Grouped Information Sets
What do you mean, that was not today's subject?
Of course it was, if you cannot concentrate even for one hour, how do you hope to be able one day to lecture and write scientific articles read all around the World?
See you tomorrow Glub students, sorry, that is the defect of bad science, you start using words any way without any content.
