Mathematics Physics on the savannah *
He felt even before the show. It is still extraordinary admit it, make out the scent of the enemy among all the rich smell of the savannah.
The other had advanced cautiously against the wind, to avoid being spotted. But the breeze had suddenly turned. Oh, just a few seconds, but it was enough to reveal its presence.
The heart of our hero jumped but it showed nothing. He knew whence came the smell: somewhere behind that little thicket fifty yards of him. He also knew that in a sprint, one could reach a top speed of fifty km / h, so that he could not exceed thirty km / h. So tell me, what can we do, alone and unarmed, against a tiger hundred and twenty-five pounds?
The vegetation around was quite high and he said that the beast would be closest possible to him before triggering his attack. So do not panic, "he said. Casually, he continued his wild berries throwing everything around peeks.
Then he saw the tree, alone there in the middle of the savannah, small but well-branched. Just big enough to raise him, but just small enough not to support one hundred and twenty-five kilograms of the beast behind him. God blessed refuge in his great wisdom had planted there, especially for him, he would have sworn. Never did tree had seemed so beautiful.
On reflection, he said however that God, even if his cherished creatures, also liked the experience. Unless it is because he had a touch of malice, because otherwise why would he put this magnificent tree with a good hundred yards? It is correct to say that the designs of Providence are inscrutable, do not you think?
"Come, come, do not panic," said our hero again. We must at all costs avoid giving a pretext for another that triggers the attack now. "Judge for yourself: to thirty km / h (or 8.33 meters / second), our hero takes 12 seconds to cross the hundred meters that separate him from his tree hut. For its part, the assailant at fifty km / h (or 13.9 meters / second), takes only 10.8 seconds to cross the 150 yards separating him from the tree. It will therefore fall on the back of its prey before it reaches the tree.
So he continued his ride innocently to surreptitiously bring the tree savior. The hardest thing was to control the tension springs to fart he had in his legs and commanded him to embark on a wild ride. The coup
eye after he revealed that the beast was approaching it much faster than he approached the tree.
At this stage of my story, I had a good mind to let you do the math yourself to advise our hero on the distance that should exist between, on one hand, and the tree itself and, secondly, between himself and the tiger
to ensure its security. But you understand that our man has really no time to wait for the results of your calculations without knowing if you are strong in numbers. So I give you all go to his reasoning.
"If I can," he said, to get closer to twenty-five yards from that tree before this beast comes close to more than fifty meters, I'm saved. "Judge for yourself again: a little rule of three you will see that the beast would take 3 , 6 seconds to reach the tree while his meal would have already jumped into the tree in 3 seconds.
Therefore, he displayed all his cunning to get closer more quickly from the blessed tree without arousing the suspicions of the other. He pretended to chase a butterfly, threw a few cries of joy to show the other his perfect indifference and even executed a few rolled-balls. This ride nearer the finally no more than thirty yards from the tree. An innocent glance behind him to see that the other had used his antics to get closer. He was only twenty meters behind and then fifty yards from the tree.
You who have your calculator probably still throbbing hand, have probably already calculated that, at this point, aggressor and victim can both reach the tree in 3.6 seconds.
Is it because he suddenly understood the operation of its prey or is it because he could take a look at the results of your calculations or is it simply out of pure instinct, always Is it at the time that the beast suddenly roared to record in a race run at full speed with the goal left no doubt.
Our hero, his eyes wide with terror, launched his handful of berries in the air and scoot. What do I say "scoot"? It flies, it soars, the other fifteen yards behind, then to ten meters and five meters, then to two meters, then ... we do not boast enough, in my opinion, the benefits of adrenaline. Is it because the hair rising on the head have the effect of raising the subject and pull it forward or is it rather a form combustion develops in the lower abdomen and, by expelling the burned materials, prints an irresistible about? I do not know. But if you saw the jump in our hero to climb into the tree while the tiger's claws were scratching his ass, you will join me in raising a temple to the goddess Adrenaline.
The fawn turned around the long shaft with a roar of anger. Another insult to the top of my lungs to relieve the enormous stress that still lived. This racket quickly came to the ears of the family who was taking a nap a little later. They approached and when they saw the tiger, they began shouting and gesticulating in a threatening manner. The other did not ask her left and disappeared into the bushes.
So our hero descended from the tree and was greeted with hugs and shouts of joy. It's not every day that a chimp escapes from a tiger.

Yes, this story has a moral. She even has two. You never not even when I was going to tell you an adventure that touches so the tragedy without some lessons.
First, you guessed it, is that we can not overemphasize on the teaching of mathematics. The rule of three in particular. Not only that you avoid being devoured by tigers but it will also help you know if the cookies in bulk are cheaper per kilo than the pre-packaged cookies.
The second lesson is that we should all become fanatics reforestation. The virtues of trees are well known and hope that all the near tragedy reported above will encourage more of our governments to protect our forests. My dog at my side, I took this afternoon ¬ afternoon stroll along the foreshore of the island of Orleans (where there is not one Tiger I assure you), waved his tail in approval. It's crazy affection for this little beast for trees. Should one day I taught him to climb not just to piss. A tiger would make mincemeat of a chihuahua, do not you think? * Extract
