Why Does My Jaw Hurt?

say that in "Solstice," ago "sun"

Hugo seems unhappy in the midst of all this snow. And say we're only on December 19. Winter does not begin until 21 at 11:38 p.m., when the apparent position of the Sun seen from Earth deign to reach its northernmost extreme, thus causing a new winter solstice !

Frankly, I do not like to dwell on the weather. I prefer the one that actually happening, because it is still less (com-) understandable. But finally this year it seems we are well served. No one can really believe that this will eventually improve, whether short, medium or long term. If you want my opinion (but that's just opinion): we're screwed! It

are the little annoyances that affect us all, of course. Mainly traffic problems. Two days ago, a friend slipped a total loss ... in the end. No material damage, but - anyway - not funny! From our side, our supply of heating oil declines dramatically. Impossible for the moment at least until our truck arriving vessel. Finally, let's say it could happen ... but probably not again. We are watching an unlikely thaw when the snow never stops falling.

In all this, neither our friend nor we are most unhappy. She had secured "omnium" (as they say in Belgium) and - apart from the fear and inconvenience - it will come out with it. Ourselves, if there were more than oil, yet have a quantity of wood that will allow us to heat the main rooms of the house for at least a month! No cause for alarm unnecessarily.

But what about those who - for whatever reason - find themselves on the streets without shelter or other real future? What about those who are stuck on a highway, professional or otherwise, land or air, without hope of moving towards a finish that never stops does not happen? What about those who do not even have a little oil or wood to consider somewhat warm? What about those who see all their professional activity blocked by these white flakes? What about ...?

The probability of having a white Christmas is growing by the hour! Big deal! Me, it makes me rather mope!

Why such beauty?

As far back as I remember, I never liked the snow. This is probably due to two events : Very young, there was a finger crushed by a sledge with sharp steel blade. In fact, I do not know if it was my finger or my brother, but until then I had trouble understanding that the pleasures of winter could be associated with suffering. A few years later, there was a great battle of snow-balls in the early evening. One of them came on my face, right in my eye. It was only later that I noticed that the glass they had remained in the ball! As incredible as it is, I found the next morning, my glass eye! But I was definitely disgusted. Since then became conductor of both vehicles with 4 or 2 wheels, I discovered the disadvantages - to use a neutral term - snowfall Blocker.

short, I do not like it. So why is it so beautiful? Results ride around and around the house ... It is discouraging, right?

Online 20 Questions Genie

praise of diversity

The box shown in the figure four compartments of equal size and a perimeter of 112 cm. What is its area in cm2?

That's the problem - including the book excerpt practices of open problem , Gilbert and Michel Arsac Mantis (CRDP Lyon, 2007) - which has been recently raised a family, for my beloved wife. Three of us to look and we left all three in different directions. One tried to put all this into an equation, the other issued heroic assumptions. Personally, I found it quite easy and I present here the fast that I found.

in itself, regardless of the solution to this problem. What is interesting is to see that - facing the same problem - each person took a different path (and there are others yet). None of these roads was fundamentally wrong. Some are no doubt easier than others but they all led to the solution.

This applies almost always when this problem is presented to an audience, mathematician or not. Beyond this mathematical problem, one might think that is exactly the same face to any other "problem" ... family problems, social problems, professional problems, health problems, problems of life!

It is rewarding to first realize that facing such a problem, there are several ways to solve it. According to our personality, we will choose one or the other, but that does not mean we have the "right" way. There are others that also result in resolving the situation. Some are more complex than others, but the level of complexity does not it depend on the degree of perception of the person placing the solution in practice? In other words, a track I can seem very complex but in fact be very simple for anyone who develops it.

These different tracks, these different approaches to the solution often create misunderstandings harmful if not perspective. Take for example any ethical or moral issue. This is not because the other has an approach angle different from mine that it necessarily wrong. If already facing a simple mathematical problem, there are different possible starting points, what should we think of moral or ethical problems that are both complex and both open in the sense that no one "answer" as possible?

When I was asked this mathematical problem, I was very happy to have found a quick and easy simple solution. Seeing my family look, not without difficulty, some interesting solutions in itself, I was really challenged: have not we too often tend to think that the answers to complex questions are simple when we see from our point of view, when in reality they vary depending on the personality of each of us?

The truth is rarely universal. It is built around what each perceives reality. Far from being a limit to human intelligence, this variety of approaches is what makes all the wealth.
