In Appreciation of Maurice Allais (1911-2010)
The New Physical Field of Maurice Allais
by Laurence Hecht

October 24, 2010
Maurice Allais, French polymath and 1988 Nobel laureate in economics, died Oct. 9, 2010. We present here an appreciation of the work in physical sciences by this extraordinary genius, which included groundbreaking experimentation with a paraconical pendulum demonstrating the existence of a new physical field. Professor Allais graduated in 1931 from France’s École Polytechnique, first in his class. and later served as an administrator in the Bureau of Mines, professor of economic analysis at the École Nationale Supérieure and research director at France’s National Center for Scientific Research, among other responsibilities.

Maurice Allais’ physical researches are often viewed as a counter-position to Einstein’s relativity theory. Professor Allais indeed presented compelling evidence that the speed of light is not independent of its direction, and that therefore this precept, which is at the foundation of the special and general theory of relativity, renders the theory invalid. That shocking possibility much intrigued me in 1998, when I first learned of the work of this French genius whom I later came to know both as a friend and a source of scientific inspiration. I shall touch only briefly on that aspect of Allais’ work here, rather emphasizing his own experimental researches with the pendulum, leading to the identification of a new physical field, which I believe constitutes the most important of his contributions to science.
As Einstein’s unique formulation of the relativity of spacetime subsumed the existing laws of mechanics in a new and more comprehensive framework, it would only be the discovery of new physical phenomena that could fundamentally un-

dermine this conception. Einstein’s 1921 visit to American physicist Dayton C. Miller, and his later published comments on the Mount Wilson experiments, indicated his openness to this possibility. Miller, who had taught at the Case School of Applied Science in Cleveland with Albert Michelson’s collaborator, the chemist Edward Morley, was then attempting to demonstrate with an improved apparatus that the Michelson-Morley experiment had not produced a null result, but rather one which was in accord neither with the assumption of Einstein
that there was no ether—that is, a medium through which light and other electromagnetic waves propagated— nor with the older view of a stationary ether. Einstein encouraged Miller, noting that if the experimental results should prove him wrong, a new theory would be required. That exchange, and Miller’s experiments, played an important part in Allais’ thinking. However, that is not the best way to introduce the reader to the significance of his work.
The Paraconical Pendulum Let us rather go directly to certain experiments with a unique sort of pendulum, conceived in 1953 and carried out by Professor Allais and assistants from 1954 to 1960 in a laboratory in Saint-Germain, and during part of one year simultaneStudio Harcourt Paris ously in a quarry at Bougival, some kilometers distant. The idea for these experiments had come from Allais’ conviction that the propagation of the gravitational and electromagnetic actions requires the existence of an intermediate medium. It would not be precisely the ether as conceived by Augustin Fresnel early in the 19th Century, but a modification of it, for this ether could not be motionless in relation to the fixed stars, as had earlier been assumed. A magnetic field, whose geometric expression in the form of a whirl is easily demonstrable, would

same. However, as Allais lamented, despite

the installation of Foucault pendulums at

many universities and public buildings

around the world, no study of the finer mo-

tion of the pendulum had ever been con-

ducted over an extended time period.

Experiments with the glass ball pendulum

did not provide definitive answers to his

original hypothesis, and, unable to obtain a

device for producing more powerful mag-

netic fields, Allais turned to a study of the

anomalies in the motion of a short pendu-

lum. For this purpose, he constructed a de-

vice which he called a paraconical pendu-

lum, suspended such that the full weight of

In 1861, Léon Foucault had famously dem-

onstrated that a long pendulum, mounted so

that it was free to swing in any vertical plane,

would gradually change the azimuth of its

plane of oscillation, turning through a full cir-

cle to return to the starting position after a

length of time which depends upon the geo-

graphic latitude. At the installation in Paris

where Foucault first demonstrated the effect,

the pendulum took about 32 hours to return to

the starting azimuth, while at either of the

poles it would take just 24 hours. Foucault

had found a means to demonstrate the rota-

tion of the Earth from a point upon the Earth. It

was an astounding demonstration, followed a

Figure 2 MEASURING CIRCLE
The experiment was conducted by allowing the pendulum to swing freely for a 14-minute period every 20 minutes. The azimuth attained was determined by a graduated measuring circle capable of attaining an accuracy of 0.1 centesimal degrees (Figure 2). (There are 100 centesimal degrees in a right angle and 400 in a circle.) On each re-launching, the ball bearing was replaced with a new one, and the azimuth attained on the previous trial was used as the starting azimuth. The bearing surface was changed at the start of each week. These observations were carried out continuously day and night for periods up to a

month during June and July 1955. Three years later, simultaneous experiments at two locations established the same results.
Because of an asymmetry or anisotropy in the modulus of elasticity of the upper support, S”, there was a preferred azimuth to which the pendulum might tend to return, barring other effects. (The direction is indicated by the arrow PQ in Figures 3 and 4.) As a result, the pendulum did not rotate through a full 360°, like the Foucault pendulum, but rather varied its azimuth over a range of about 100 centesimal degrees (one-quarter circle). It was the periodicity of the variations in azimuth which proved to be most interesting. After discounting for the Foucault effect and the “return effect” due to the anisotropy of the support, Allais found very strong evidence for a periodic effect, which could not be attributed to any known cause. Harmonic analysis by a mathematical technique known as a Buys-Ballot filter showed that the periodicity manifested itself on a cycle of 24 and 25 hours. Analysis showed that the unknown disturbing influence or influences giving rise to this periodicity was of a strong character, with a strength on average and as a whole about twice that of the Foucault effect.
Luni-Solar Influence? The rising of the Moon occurs later each day, by an amount varying from about 20 to 80 minutes and averaging about 50 minutes over the course of a month. Thus, the position of the Moon overhead obeys a cycle of about 24 hours 50 minutes. This fact might lead one to suspect that the observed cyclicity in the pendulum data is due to the gravitational effect of the Moon, or the combined effect of Moon and Sun.
