The forecast is that by the end of the year there will be around 12, visits. During the month of November, a new immersive experience for visitors, called SINERGIA, will be inaugurated, which will show the public real data obtained with the telescope.
This year it will be devoted to the computational methods which are used in different fields of astrophysics to simulate the dynamics of fluids. The school will take place in the assembly hall in the Guajara Campus of the University of La Laguna.

News type. With the hex nuts at rest he taps one and it begins to swing softly. Within seconds the other nut also begins to move. Eventually the two hex nuts begin oscillating as they transfer energy from one to the other. And it all started from that first, small tap.

If we could harness the dynamics behind the butterfly effect, we could move spacecraft with very little fuel, extend the life of satellites, or send robots to the moon inexpensively. Rafael de la Llave, Georgia Tech. For another example, think of a person who pushes a child on a playground swing.
Spacecraft typically follow conical routes that have been found to use the least fuel.
But those routes still require long detours to get to the final destination. Those detours, of course, burn fuel.

However, this is in spite of the fact that it's actually false: A butterfly in Brazil can flutter as hard as it likes, but it still can't whip up a tornado in Texas. Each flap of a butterfly's wings exerts a pressure on surrounding air molecules in order to thrust the insect upward. Each flap causes a tiny change in the air pressure around the butterfly, but this fluctuation is insignificant compared to the air's total pressure, which is about , times larger.
Changes in air pressure are one of the key factors involved in changing the weather, but in the case of the butterfly, the air molecules easily absorb the blow of a wing flap, so that a few inches away from a butterfly, the turbulence it causes will have died down.

Orrell, who has a doctorate in prediction of nonlinear systems from the University of Oxford, writes about prediction-making in fields such as meteorology, biology and economics for both scientific and lay audiences. His best-selling book "The Future of Everything: The Science of Prediction" Thunder's Mouth Press, describes the extreme difficulty meteorologists face in forecasting the weather, which is so sensitive to changes in atmospheric conditions like pressure and temperature that it cannot be accurately projected more than a few days in advance.
An estimation of the temperature that is off by just a fraction of a degree-Celsius leads to a cascade of errors later, making predictions that look out beyond a few days, but less than a few weeks, particularly challenging. However, "the changes that make a difference are far bigger than a butterfly flapping its wings," Orrell said. People started applying chaos theory to a lot of systems and saying, 'Well, this property is sensitive to initial conditions, so we can't make accurate predictions.
In fact, according to Orrell, only in greatly simplified models of chaos like the strange attractor do microscopic changes have huge consequences, escalating and ultimately causing the attractor to diverge from the path it otherwise would have taken. More complex computer models like those used by meteorologists are much more robust.
As Orrell and a team of several other mathematicians demonstrated in , inputting butterfly-flapping-scale disturbances into these weather models don't cause the outcomes of the models to diverge.
