The true history of seven heavens and the eighth that it's the Earth

Fourier formulate any type of periodic function might seem complex could always be represented as a sum of harmonic functions. Of harmonic functions are of many types but the most popular is the Sinus. Sinusoidal functions [ f(t)=A*sin(wt) or f(t)=A*cos(wt) ] ; are the trigonometric function with a parameter that is the amplitude is maximum and minimum value of this, a second parameter w ( omega ) named frequency, and a variable t ( time usually but not necessarily also be a distance). Then this periodic function can be represented by combining different harmonic functions which are chosen appropriately amplitudes and frequencies. These harmonic functions can describe many things, but the most popular description where it commonly is often associated in music and sound. The voice for example we represent it with a histogram of pressure variations at one point depending on the time, these histograms are terribly complex, just like musical instruments, but when we play an instrument ...

Warsaw Climate Conference has been a fault. But nobody surprise of it, every year there is Climate Conference and the result is equal: good words and nothing more. In Doha conference was even ridiculous, because how they want to speak about CO 2 reduction in home of great world producer of Oil ? One sign of their redundancy is the very poor coverage by the press, we could name it as the “ hidden conference ”; people can say more or less what Kyoto Protocol is, but asking the signatories they can’t say what about the current commitments.   Obviously specialized press has echoed of event. They showed to word the desperation of scientific world, the cynicism of skeptics and paralyze of politics. Fiona Harvey talks in “ As the Warsaw climate talks end, the hard work is just beginning ” about work that countries have in home to prepare the 2015 conference. I haven’t any doubt of countries will but the reductions of 2015 had been to apply today; in fact CO 2 has increased r...
