Science Week in Andalusia

A recent the Unesco report echoes the lack of engineers , leading to a global brake on economic development.
Aversion to Science and Technology of our students, in any high school course, how many matemafobos there?.

PHYSICAL AND BEAUTY WITH 10 EXPERIMENT OS

What are the tests most fantastic made in physics throughout history? From Department of Physics, University of Granada, Miguel Cabrerizo has chosen a dozen proposals and submitted them to students in secondary schools and two purposes: to disseminate important scientific advances made by man to Throughout its history, and show in a fun, unjustly considered boring work of physicists.

The Sciences Faculty of the University of Granada becomes during the Science Week from 8 to 21 November in an experimental gallery where students from primary and secondary may take a tour of the 10 most beautiful experiments in physics. Physics Professor Michael Cabrerizo has chosen a dozen trials to show their stuff early, participants travel together with their explanations. One way to disseminate physics beyond memorizing formulas in class.

A group of students is Cabrerizo explanations about the Foucault pendulum

Among the experiments proposed in this exhibition-laboratory experiment found and l Ernest Rutherford for the discovery of atomic nucleus, represented by a mechanical model illustrating the complex trial conducted by the scientist. After bombarding gold foil with alpha particles and saw that they were diverted, refuted the previous atomic model postulated and enacted Rutherford's atomic model, in which it is proposed that the atom is made up of a positively charged nucleus and a series negatively charged electrons orbiting around it.


The drop experiment Millikan Oil , is represented in this conference by a machine similar to the physical U.S. used to determine first the electron charge. By suspending oil droplets within the walls of a single capacitor, could deduce the electron charge, applying different voltages to the droplets in the condenser.


The Foucault pendulum is also exposure. An experiment with the French physicist who could prove that the Earth's rotation can be represented by a fixed platform system in which a pendulum swings freely.


experiment in double Young slit light, the English scientist Thomas Young demonstrated the wave nature of light, ie light is a wave. In the presentation, has exemplified the double-slit experiment with photons. In 1961, we performed the same experiment with electrons, confirming the same results.


With trial balance of Cavendish, the British physicist and chemist won the first measurement of the mass of our planet Earth.


Another experiment is Newton's prism. A simple mechanism by which the English physicist, showed the refraction of light. Their experiment yielded information on the complexity of visible light, composed of different colors that precisely match the colors of the rainbow.


As for the Michelson-Nerly , was designed to measure the absolute speed of motion of the Earth in space using light waves. The negative result of this experiment was the ultimate test for ruling that electromagnetic waves do not require any material medium to propagate or whatever it is, that these waves can travel through a vacuum. This statement was useful to Albert Einstein to formulate his Theory of Special Relativity.


The calculating the perimeter of the Land of Eratosthenes is another fabulous experiments conducted in the history of physics. The famous Greek mathematician, by calculating the shadow of two sundials, one located in Siena and the other in Alexandria, and knowing the exact distance between the two cities, quite rightly calculated the extent of terrestrial radio. Among other things, the fascinating thing about this experiment, which took place about 200 years before Christ, which demonstrated the enormous seriousness of ancient science studies.


Finally, the two remaining experiments are carried out by the great Galileo Galilei. The experiment Galileo Inclined Plane, which is represented most curiously in the laboratory, was what enabled him to say that the distance traveled by an object is proportional to the square of elapsed time.


The other proposed experiments as the most beautiful experiment is e l Free Fall also made by this distinguished Italian physicist. With his experience, Galileo challenged the proposal Aristotle's freefall and confirmed that in the absence of air resistance exerted by the two bodies of different mass fall into the void with the same uniform acceleration.

addition 10 most beautiful experiments in physics, Faculty of Sciences has set a total of 79 different itineraries that can be developed by students of secondary schools enrolled in them, addition to permanent exhibitions and scientific projections that will be offered during those days. In this edition, apart from the influx of the general public, will carry out the different routes around 2,000 students from 39 Secondary Schools, which represents an increase of 60% over the previous year's attendance.
