		<title>You know why the fruits are eaten after a meal?</title>
		<description><![CDATA[The fruit on a full stomach does not make you fat: The calories intake is the same whether it is eaten between meals, or if the consumption occurs at the end of the meal. 
The same goes for its vitamin content. Indeed, the vitamin C in many fruits (kiwi, strawberries, citrus fruits &#8230;) favors the absorption of iron in other foods (meat, fish, eggs). 
Finally, concluding the meal with fruit is useful to avoid the temptation to eat sweets, often high in calories and fat.
Eating fresh fruit as a snack, ...]]></description>

		<title>Why Arabs write from right to left?</title>
		<description><![CDATA[Arab alphabet
The reason is historical. The current alphabet is of Arabic Aramaic source. The first known texts written in Aramaic dates from the IX century BD. This language originated in Syria, but already in the early first millennium BD spread
in Mesopotamia and later in Palestine. 
The Aramaic alphabet, in turn, derives from the oldest form of alphabet of the Phoenicians (whose country was the current Lebanon). The Phoenicians invented the &#8216;alphabet, towards the end of the second millennium BD. Initially, they possessed the letters in a kind of serpentine from ...]]></description>

		<title>U know why the fish stinks?</title>
		<description><![CDATA[
The smell of fish (fish odor) is not due to the fact that the fish died and then begin it&#8217;s decomposition but is due to trimethylamine, a compound that is volatile form after the death of fish, some proteolytic bacteria (demolition of protein structures) of the genera Achromobacter, Pseudomonas, Micrococcus, Bacillus putrefaciens Altreromonas and begin to colonize the meat. 
The process continues on a regular basis over the period of edibility of fish, and this explains why the smell (fish odor) increases with time. Then stabilizes.
Cool?
The measure of the amount ...]]></description>

		<title>U know why the fireflies glow?</title>
		<description><![CDATA[The firefly is an insect which is particularly known for its characteristic luminescence. This animal has special abdominal organs, which cause a chemical reaction with the organic synthesis of an enzyme called luciferasi.
The light produced is useful because from these insects it can be exploited as a mean of communication between individuals of the same species, probably as a sexual recall as well, that could draw the prey too. It is curious to note that the adult insect issues, generally, intermittent light, while the larvae shine light sets.

		<title>U know how to calculate the age of a horse?</title>
		<description><![CDATA[The age of a horse is determined by observing its teeth, because the adult male horse has 40 and the female 36 (because of missing brackets) as&#8217; distributed: 12 molars, 12 premolars, 4 bands, 12 incisors, which are also divided into: 2 Picozzi, 2 median and 2 cantons (or lateral). The spaces between the incisors and the premolars are called bars.
When sprout the first front teeth the horse reaches its first birthday. At 4 years there are 8 and 5 there are 12. Given that his life expectancy is around ...]]></description>

		<title>U know why &#8216;ostriches&#8217; hide their heads in the sand ?</title>
		<description><![CDATA[ The reason for this behavior on the part of ostriches is ignored by everyone, why? Simple &#8230; because it&#8217;s false! Indeed, the popular belief that ostriches put their heads in the sand in case of danger, is wrong and has never been recorded.
However, when there is no other possibility of escape evident, a bird can lie down on the ground with head and neck stretched forward and remain firm in the hope that it is ignored by his enemy. This strategy has similarly taken by a bird in hatching ...]]></description>

		<title>U know why there are most months 30 or 31 days long ?</title>
		<description><![CDATA[This has resulted from a compromise. Initially, months were mostly 29 days long and the average length of a month was 29.5 days which is the time taken by the Moon to orbit the Earth. However, this resulted in a year of only 354 days while the orbital period of the Earth is 365.2422 days. As a result, the calender became out of sync with seasons which was bad. This was initially corrected in an arbitrary way by adding a 13th month, but soon the calender was thrown into severe ...]]></description>

		<title>U know why &#8216;you cry cutting the onion&#8217; ?</title>
		<description><![CDATA[ In onion there are molecules that contain one or more of sulfur atoms: the organic sulphides. When cutting the onion these sulphides are combined with another substance present in different layers, &#8220;the allinasi enzyme&#8221;, which degrades amino acids and volatile odorless. These amino acids, reacting with water covering the cornea, are transformed into acids, mainly sulfuric and sulphide. As corrosive substances, the eye tries to rid activating the lacrimal glands. From the&#8217;90 in different parts of the world  , it attracts the attention of scientists, agronomists and geneticists. How ...]]></description>

		<title>U know why the &#8220;fractals&#8221; are called so ?</title>
		<description><![CDATA[The history of fractals in the strict sense is fairly recent. Suddenly opened in 1975 with the revolutionary publication &#8220;A Theory of Fractal Sets&#8221; of mathematician Benoît Mandelbrot, which became the basis of its fundamental text and manifest.


In &#8220;The Fractal Geometry of Nature&#8221; Mandelbrot, has coined the term fractal which derives from the Latin word &#8220;Fractus&#8221; (split), because the size of a fractal is not whole. The fractal geometric figures are characterized by repeated indefinitely until the same reason on an ever smaller scale.

The characteristic of these figures, a feat ...]]></description>

		<title>U know why one minute has 60 seconds?</title>
		<description><![CDATA[With the birth of mechanical watches, around the thirteenth century, it was established the habit of splitting time in 60 smaller parts, all equal, each of which was called in Latin &#8220;pars minuta prima&#8221; which means &#8220;first small part&#8221; then cut short &#8216;minutes&#8217;, and these in turn were divided into 60 shares still other smaller, each of which was called, in Latin, secunda pars minuta (second small part), then cut short&#8217; second &#8216;.
The choice of the number 60 is traced back to Sumerian, which had divided the circle in 360 ...]]></description>
