Washington: According to recent study, position of Leaning Tower of Pisa can be best determined when one is in upright position. And the fact is scientifically proven. Newton’s laws of motion states that an object will fall only when centre of mass lies afar its base.

Scientists from the Max Planck Institute in Tubingen, Germany, have discovered that though physical laws governing object stability are represented by the brain, but a falling object is better judged only when one is in upright position. Side position doesn’t give the clearer view.

The reason is simple and clear, gravitational force is not sensed directly. It is the tortuous effects of gravity that are sensed. The research in the field is not new as somewhere in mid 19th century a scientist named Hermann Aubert slanted one side and observed a vertical line as being tilted towards him. He then stated in his theory that brain combines visual information and vestibular information to determine direction of gravity. It is different from interior depiction of body point of reference.

During the study observers were equipped with laptops, and they were tested in both the position upright and on side. In both the position perception of object stability were taken. The research team found that our insight or sensitivity whether an object will fall biased to perceived direction or in gravity exact direction depends upon our self position.

Heinrich Bulthoff director of Max Planck institute said that “This is another fine example suggesting that brain accurately represent objects in the world. It combines information from multiple sensory organs that autonomously do not provide an accurate demonstration of the physical world.”

The research further said that visual and vestibular body sense prompt the brain to make use of this superfluous information and an optimal perception and action is maintained. This process is at its best when sense is poor or lost. The research is going to prove very beneficial in suggesting the thought process of human.
