What are alones?
The pinions are a hypothetical group that would
indistinguishable particles located between the two families of particles queens of quantum mechanics. These
are bosons, which include among others, the photons and the Cooper pairs of fermions, and - most notably
electrons. According to theoretical physicists, the alones,
still only exist as mathematical entities, would be closely related to the existence of an intriguing mechanism
natural and powerful
high temperature superconductivity, which could be applied to the brand new copper oxide superconductors.
What is mad cow syndrome?
esponguiforme Known technically as bovine encephalopathy, or BSE,
mad cow disease was first identified by
veterinary team headed by GAH Wells, England, in cattle
the UK in November 1986. Since then, more than 50,000 cows have been
to be destroyed. Animals affected by the disease progressively thinner,
produce less and less milk, are shy and nervous, gnash their teeth and suffer
continuous tremors. In advanced stages of the disease, the cow is shown
aggressive with their partners and even the livestock, walking awkwardly and often falls
. The cause of BSE remains unknown, although it is thought
infectious agent, perhaps a new virus, or a prion, a pathological and amended of
a normal brain protein.
What is a knot of rats?
In some old books of zoology, shows the cases of groups of between five and 12
young rats with their tails intertwined mysteriously. This is what is known as knots or tangles
rats. Currently there are very few people worldwide who claim to have witnessed such
natural spectacle, so that your explanation scientific
very difficult, but certainly not lacking curious theories.
eighteenth century, it was believed that the loops of rats occurred when they were born with the umbilical cords
soldiers.
What is entropy?
Entropy is a quantity that gives us the degree of disorder or chaos in a system. The chemical reactions or physical
have the property that
occur only in the sense that the entropy increases or remains. Is taken as zero
entropy of pure substances perfectly crystallized at a temperature of
absolute zero (-273 ยบ C). The entropy increases with the volume and temperature. By increasing the volume
growing number of positions available for a molecule, and therefore reduces the chance
several molecules that may be forming a group
ordered. For its part, the temperature increase triggers the disorder, because different speeds
molecules that can be grown, which is harder to predict
position.
WHAT is the origin of the legend of the Pied Piper of Hamelin?
This popular legend, in which a flutist takes to lure all the children of Hamelin
Germanic people, after the people break the promise
pay for having got rid of a plague of rats, has its origin in an event that occurred in 1212
. It is said that in that year, about 40,000 children
Germans abandoned their homes and, guided by a boy named Nicholas, crossed the Alps and arrived in Rome
. In France, about 30,000 children joined the trip, which was called the Children's Crusade
.
leaders and survivors of the expedition met with Pope Innocent III,
who were invited to return to their homes. Many turned a deaf ear to advice
the Pope and embarked on different ships bound for North Africa, where
were sold as slaves.
