We have researched on an effect
which is known in Nordic cultures
since it's observed there.
It's called the Mpemba effect.
It's been known since the age of Aristotle.
Aristotle said:
"It is well known that
if you leave a liquid to freeze outdoors,
it will freeze faster if such liquid is hot."
Our new approach is for this system
that we perfectly know how it works
the particles that there are within our system
we know how they interact, how they evolve,
we can simulate them in a computer, perform analytical calculations,
predict and know how and when the Mpemba Effect will occur.
In fact, we didn't just find out
that the hotter the liquid, the faster it cools.
but also the inverse effect.
The coldest liquid also warms up faster.
Until our work, and a little before some other guys,
it had never been studied scientifically
from a theoretical point of view or more seriously.
It had always been studied as a curious fact.
90 % of publications
are in popular science magazines.
We have found relevant
that we can define the initial conditions,
how to prepare the system,
for the effect to occur or not.
Both the warming and the cooling.
What was complicated was to realize
that was going to happen in our system
and to provide a complete description, both microscopic and macroscopic,
why this effect happened, at least within our system.
For this research
two researchers from Universidad de Extremadura,
Fra and Andrés have been collaborating with us.
And we also have a researcher from Universidad de Sevilla, Antonio.
Our main interest is to be able to measure experimentally
this Mpemba Effect.
It would be a great achievement since nobody has been able to measure it yet.
