ONE SMALL STEP

This is our little tribute to the greatest explorer of all times.


"Neil Armstrong was among the greatest of American heroes - not just of his time, but of all time.
When he and his fellow crew members lifted off aboard Apollo 11 in 1969, they carried with them the aspirations of an entire nation. They set out to show the world that the American spirit can see beyond what seems unimaginable - that with enough drive and ingenuity, anything is possible. And when Neil stepped foot on the surface of the moon for the first time, he delivered a moment of human achievement that will never be forgotten.

Neil's spirit of discovery lives on in all the men and women who have devoted their lives to exploring the unknown - including those who are ensuring that we reach higher and go further in space. That legacy will endure - sparked by a man who taught us the enormous power of one small step"
US President Barack Obama



Safe travels, Commander.

ASTOUNDING FACT: EVERYBODY NEEDS A BOSOM


It's so sad that the discovery of the Higgs boson, one of the biggest leap forward for science in the last one hundred years, has been just an usual line among breaking news. If nobody thinks that is something to discuss about, we do. Let them talk about Paris Hilton starting her dj career.

The Higgs boson is one of the final puzzle pieces required for a complete understanding of the standard model of physics—the so-far successful theory that explains how fundamental particles interact with the elementary forces of nature.
The so-called God particle was proposed in the 1960s by Peter Higgs to explain why some particles, such as quarks—building blocks of protons, among other things—and electrons have mass, while others, such as the light-carrying photon particle, do not.


Higgs's idea was that the universe is bathed in an invisible field similar to a magnetic field. Every particle feels this field—now known as the Higgs field—but to varying degrees.
If a particle can move through this field with little or no interaction, there will be no drag, and that particle will have little or no mass. Alternatively, if a particle interacts significantly with the Higgs field, it will have a higher mass.
The idea of the Higgs field requires the acceptance of a related particle: the Higgs boson.

According to the standard model, if the Higgs field didn't exist, the universe would be a very different place, said SLAC's Peskin, who isn't involved in the LHC experiments. "It would be very difficult to form atoms," Peskin said. "So our orderly world, where matter is made of atoms, and electrons form chemical bonds—we wouldn't have that if we did not have the Higgs field."
In other words: no galaxies, no stars, no planets, no life on Earth.
And no fucking Paris Hilton djing.

0 1 1 2 3 5 8 13 21 34 . . .


The Fibonacci sequence is named after Leonardo of Pisa, aka Fibonacci, although the sequence had been described earlier in Indian mathematics in connection with Sanskrit prosody.
In the West, the Fibonacci sequence first appears in the book Liber Abaci (1202), where Fibonacci considers the growth of an idealized and biologically unrealistic rabbit population, assuming that: a newly born pair of rabbits, one male, one female, are put in a field; rabbits are able to mate at the age of one month so that at the end of its second month a female can produce another pair of rabbits; rabbits never die and a mating pair always produces one new pair (one male, one female) every month from the second month on. The puzzle that Fibonacci posed was: how many pairs will there be in one year?
At the end of the each month, the number of pairs of rabbits is equal to the number of new pairs plus the number of pairs alive last month. This is the Fibonacci sequence, which is intimately connected with the golden ratio.
Applications include computer algorithms such as the Fibonacci search technique and the Fibonacci heap data structure, and graphs called Fibonacci cubes. They also appear in biological settings,such as branching in trees, Phyllotaxis (the arrangement of leaves on a stem), the fruit spouts of a pineapple, the flowering of artichoke, an uncurling fern and the arrangement of a pine cone.

ALLA FACCIA DEL TOMTOM

Improvvisamente mi sento terribilmente insignificante...
