One says of Galileo, that he was not able to convince his contemporaries that the Earth was round and turned. As it is known, it was Founcault in the middle of century XIX, but of two centuries after Galileo, that demonstrated publicly that the Earth rotated. It suspended to a pendulum under the cupola of the Pantheon of Paris, using a cable of 67 meters in length and one sphere of 28 kg. The plane of oscillation of the pendulum should remain invariable in the space if doesn't intervene external forces, but as the Earth it rotates on their own axis, all the present understood that the lateral movement was caused since by the rotation of the Earth the inertial moment it is conserved.
The chance or the bad fortune, according to as it is watched, I had to work in the station of Chamartín (Madrid-Spain) in a company of paquetería. In my work it such took by platform a wheelbarrow that was able to throw of about 10 hooked cars or but as if they were the "train of the witch" that put in the fairs of the towns, but with wheels. Very similar to the cars that transport the suitcases in the airports.
When they assigned to me a wheelbarrow already said me that it had to circulate around the platforms by the left, to avoid that the cars to the route fell. Personally, I experimentally proved the veracity of this fact in but of an occasion having my companions reason, with the consequent reprimand of my heads, machinists, inspectors of circulation and others. Really, if it circulated around the right fell to the route.
Memory still that asked to them my companions why this happened. All they said to me most intuitive. The platforms are inclined towards the right! Badly they are constructed! And sure and I thought, how a station with but of 12 platforms and with a length of about 400 meters or but each one, they were going to be all badly constructed and towards the same side?
In days of rain, I made sure that the platforms spilled water correctly, half of the platform towards a side and other half, towards the other. That is to say, correctly they were constructed. Then, why it was necessary to circulate around the left in the platforms?
Reading scientific books in those years, towards 1,993, I tripped over the Coriolis force. The example of which when clearing has been always put the cork of a full water washbasin, defeat in the entrance to the drain in opposite sense of the needles of the clock in the North hemisphere, and the South hemisphere on the contrary. Although the random movement can be able to cause that it turns the other way around of which would have, being greater than the Coriolis force. The effects of the Earth rotation are of great importance in the study of the wind systems, the marine currents and the launchings of rockets.
Colón as marine he knew it perfectly, although did not know why. He knew that to arrive at the "Américas" of the easy way but, was necessary to go first a Canary, so that the marine current pushed to him there towards and returning, towards Spain, being pushed to him the same marine current.
Although it seems the same physical law, the force Coriolis and the revolvable movement of the pendulum, they have their big differences. Of agreement that takes place for the revolvable movement of the Earth on their axis, but while the force Coriolis is accumulative, the revolvable movement of the pendulum is always constant. For example, the right part of the rails of the trains in the North hemisphere is but worn away, caused by the boxcars that it takes the machine when making effect " whip ". Alone in theory, because in the practice it is completely unobservable for the great resistance to the waste of the rails (I have verified it personally after taking but of 13 years in you hire rail). Also, I am assuming that the trains have two rails, one for each sense. That is to say, I am supposing that the trains always circulate in the same sense on the same rails.
That at the beginning is a small force in the first boxcars, it becomes a great lateral displacement at the end of the boxcars or in the previous example, in the cars for what the Coriolis force is accumulative. The revolvable movement of the alone pendulum depends on the observer's latitude and not of the long or big that is the pendulum.
In fact, the force Coriolis is so intense that it fixed the total number of cars that we could transport, because although circulates for the left to avoid that they fell to the road, the non alone last cars touched the pillars of the stairway, if not that it ended up incrusting being able to stop the wheelbarrow totally.
Another example would be that the right part of the bank of a river is a lot but erosionado, so much laterally as in depth that the left side in general. On the contrary, the lateral turn of the pendulum is constant the same as the day movement of the earth, because the inertial moment is conserved (well the engineers of the artificial satellites know it when they install the gyroscopes for not losing the reference coordinates in the space).
I have here to clarify that the form and intensity of the Coriolis Force depends of if the object in movement is in free or parallel fall to the floor. If it is in free fall, the object in movement will move toward the East being null in the poles and maxim in the equator to the perpendicular being to the terrestrial axis. On the contrary, if the movement is parallel to the floor, that is to say, perpendicular to the previous movement or free fall, then the objects in movement will move toward the right in the North hemisphere and in the South hemisphere toward the left, being null in the poles and in the equator, although increasing since of intensity toward the equator is every time but far from the terrestrial axis. What happens is that it becomes null in the equator to be the object in movement in a parallel plane to the terrestrial axis.
That is to say, the Coriolis force causes a lateral displacement caused by the revolving Earth movement on its axis. Then following this same reasoning, also the Earth has the another very many but weak revolving movement: the movement of translation around the Sun more movements Exist other many as the one of precession of the equinoxes but I am going them to discard, since they are excessively weak.
As Newton taught to us to Sir Issac, considered like the greater scientist of all the times, the Earth turns around the Sun thanks to the gravitational force, causing a revolving movement. Then, if we make the same experiment with the cars to detect the Coriolis Force to the dawn and then 12 hours but it takes, in one this small one would be added effect and in the other experiment it would be subtracted. This value experimental it would be twice as much that this small effect, as it is also it the parallax anua of a star.
Of here it is discovered that this effect is independent of the latitude, being 365 times but weak with regard to the place where we have carried out the experiment, although the experiment develops it in any place of the planet.
That is to say, to be able to get an experimental measure of 2 millimeters that would be exactly inside our mensuration possibilities, (a millimeter toward the left and 12 hours but it takes, another millimeter toward the right), we would need that the Coriolis Force causes a lateral deviation from our cars of 366 millimeters to the 06:00 Local Time and 364 millimeters at the 18:00 Local Time, provided our place of the experiment is located in near latitudes at the Ecuador, where the Coriolis Force is maximum.
This would be truth if Newton were right, but Einstein taught to us that the Earth moves in line straight on a cuatridimensional universe. That to us it seems to us that the Earth turns around the Sun in curve, it is because we are beings of three dimensions and we observed the universe in those same dimensions.
What do I say with this? That the weak effect that I wanted to find in the previous experiment for the movement of virement of the Earth would be nonexistent, because like I have said before, the Earth moves on line straight line around the Sun, and this concept is expandable to all the smaller other movements that the Earth has, because it will always move for the universe for its own inertia on line straight line, in an cuatridimensional universe.
It was going to obtain the same negative result that the experiment of Michelson and Morley to know the speed the Earth through "eter", and is when it appeared Einstein to explain to us that the speed of the light is independent of the speed of the observer.
Now it is when of a very subtle and delicate way, we will be able to find out the veracity of the theory of general relativity.
From always the three typical examples in favor of this theory, that have been put us they are: The advance of the perihelion of the Mercury orbit, the deviation of the light of stars near a gravitational field and the delay of the clocks. Lately we have other tests to their favor, for example double cuasar, the gravitational lenses, the reddening of the white dwarves or neutron stars, the loss of energy in a very close compact system causing a slow distance between both with the consequent diminution of the orbital speed, etc.
It is clear that these observations and experiments are not within reach of anyone. Those are needed but big telescopes of the world to check the truthfulness of the theory. The experiment that I have just edited if that one could discover with the daily means that we prepare. The force Coriolis is so intense to the being an accumulative force that although we carry out the experiment with some cars of very little quality with the crazy wheels it is appreciated perfectly since it has a very considerable lateral displacement (almost as much as the cars of the supermarkets).
In fact, it was a pain not to be able to quantify the lateral displacement in those years because I would need to carry out some how many mensurations it stops then me to make the stocking and other so many ones, 12 hours but it takes with the same cars. I believe that my boss would not understand it and also before all the passengers.
The problem of these experiments, is that as Einstein is right, in our measures they will be equal within the precision errors that we pruned to commit. We do not have to attribute them to the little precision, if not that the Earth moves in line straight around the Sun, through the space-time, in a cuatridimensional universe. A beautiful and easy form to verify the veracity of the theory of general relativity without having to resort to the great observatories or the experiments developed with the greater degree of precision.
I understand that you will ask yourselves, how it is possible to verify the theory of general relativity with a so simple and rudimentary experiment in the measurements? Then there are two options: that to anybody him to happened or something it is failed in my thesis. At the moment, I do not observe any error.
Sincerely, it would thank for your critics.
