- the observations by Maurice Allais in Paris in 1954 and 1959
- the experiment of Jeverdan, Rusu, and Antonescu in Romania in 1961
- the observations by Saxl and Allen of Harvard in 1970
- Three independent observations should be enough to convince anyone that
something is going on!

- He invented a gparaconicalh pendulum and observed the precession of its
azimuth during a number of marathon observational runs;
- He repeated some of the long-term optical sighting experiments of
Esclangon (1926);
- He re-analyzed the interferometric observations of C. Dayton Miller from
the 1920s.
- These researches all showed anomalous effects
- (And, over the same period, Allais also wrote two groundbreaking books
on economic theory, for which he received the Nobel Prize in 1988)

- cwas first observed during a total solar eclipse in Bucharest, Romania
in 1961 Jeverdan et al. were at the time completely unaware of Allaisfs
work. During the eclipse, the period of a sophisticated Foucault
pendulum (about 25 meters in length) shortened markedly. We consider
that the Allais effect and the JRA effect are probably two aspects of
one underlying phenomenon.

- From the 1950s through to 1970, Saxl and Allen operated a large torsion
pendulum at Harvard, repeatedly measuring the period over extended
experimental series taking many days. Not only did they detect periodic
deviations similar to those found by Allais, but during the solar
eclipse of 1970 they detected a pronounced increase of the period. They
also observed a weak spike during a lunar eclipse.
- (A torsion pendulum operates independently of Earthfs gravitation; the
effects are produced only by the torsion of the support wire and the
rotational inertia of the bob)

- On the occasion of the spectacular solar eclipse of 11 August 1999 which
passed over Europe, a group at NASA made a serious effort to organize
coordinated observations with Foucault pendulums.
- "The initial interpretation of the record points to three
possibilities," says Dr. David Noever of NASA/Marshall, "A
systematic error, a local effect, or the unexplored. To eliminate the
first two possibilities, we and several other observers will use
different kinds of measuring instruments in a distributed global network
of observing stations."
|

|
- In any case, the entire effort collapsed some months after the eclipse,
before the data was analyzed, when Noever and some associates quit their
jobs at NASA and founded a dotcom company. It is rumored that Noever
took all the files with him when he leftc

- Allais did not set out to make pendulum observations during an eclipse -
the 30 June 1954 eclipse fortuitously passed near Paris, and his
observation was serendipitous;
- Jeverdan planned to take his observations during the 1961 eclipse that
was scheduled to pass near his laboratory in Bucharest;
- Saxl and Allen took advantage of the solar eclipse that passed near
Harvard in 1970.

- There are no total solar eclipses during 2007. Pendulum experiments for
the solar eclipse of 1 August 2008 will be best performed in Spitzbergen
(Svalbard), which is about the most northerly location hosting any
reasonable outpost of civilization. But in 2009 there are two
magnificent eclipsesc.

months from now – the Sun-Moon line will pass horizontally 200 km above
Anchorage.

- At the maximum eclipse instants of two consecutive solar eclipses – of 3
October 2005 and 29 March 2006 – the anti-eclipse point will be very
near the island of Hawaii.
