60 Years Not Solved, Puzzle Largest about the impact of Solar Eclipse

Total solar eclipse can be seen from 12 provinces in Indonesia on March 9, 2016 could be an opportunity to solve one of the biggest puzzles in science. Puzzle unsolved for 60 years was associated anomalies pendulum motion when a total solar eclipse.

Emerging puzzle originated from the French scientist Maurice Allais observed during a solar eclipse June 30, 1954. Nobel Economics in 1988 are also fond of astronomy would see the pendulum swing toward underwent major changes during an eclipse.

Under normal conditions, the direction of the swing of the pendulum turns clockwise at a speed of 0.19 degrees per minute. Change is actually reasonable because it is associated with the Earth's rotation. However, in the observations in 1954, Allais found that the direction of the swing of the pendulum turns 13.5 degrees and counter-clockwise.

Allais observed repeated on October 2, 1959 solar eclipse of Saint-Germain-en-Laye in France. He encountered the same phenomenon but can not explain why. Anomalies that can not be revealed the cause was later called Allais Effect.

Answer search

Outlined on the website National Aeronautics and Space Administration (NASA), a number of scientists who study physics and astronomy moved outlines Allais Effect. They conducted an experiment to confirm the reset. Basically the question: Is the anomalies that were found are related Allais eclipse?

Scientists GT Jeverdan observe the motion of the pendulum during a solar eclipse on February 15, 1961 from Romania. He met, pendulum motion slowed down 1 per 2000 during an eclipse. However, the observation was published in the journal Jeverdan English.

EJ Saxl and M Allen tried to confirm Allais Effect by observing the motion of the torsion pendulum. When used Allais Foucault pendulum to move sideways, torsion pendulum moves up and down. The pendulum consists of a load suspended by a spring.

Saxl and Allen were observed at Harvard University in 1970 found that the time required to perform a torsional pendulum swing increases during eclipses. However, the experimental Finnish scientist named T. Kuusela at the solar eclipse July 22 1990 in contrast to the observations Saxl and Allen.

In 2009, eight gravimeter and two pendulums are used on the observation of the solar eclipse January 26, 2009 in China. One of the scientists confirmed anomalies as encountered Allais. However, the observation is not published in any scientific journal.

Scientists attempt to explain the anomaly encountered Allais. The general view, a solar eclipse will affect the earth's gravity and rotation. Allais Effect is evidence of the influence. However, there are other explanations.

Research T Van Flandern of Meta Research and XS The University of Wales Swansena in the UK, published in Physical Review in 2003 revealed that the anomalies that were found could be because eclipse Allais causes cooling in the upper atmosphere that affects the density and movement of air masses.

Efforts Bosscha

Head of the observatory, Mahasena Son, said that the observation Allais Effect is still continuing. "We still can not explain the exact cause," he said. "The moment of eclipse in Indonesia could be our chance to answer."

Mahasena said the observatory is currently developing a pendulum with the sensor. The device will be used to confirm Allais Effect. "If we come across, this would be an interesting research report," said Mahasena when found Kompas.com, Friday.

Team observatory will conduct field observations Kalora, Poso, Central Sulawesi. Together Universe Awareness (Unawe), Bosscha team will also disseminate astronomy and eclipse observations to the citizens. Poso itself is one of the areas in Indonesia will experience a total solar eclipse this year.
