[Physics] Pendulum Experiments of Maurice Allais

[Thomas Goodey]

Gentlemen: publication of the translation into English of 
Maurice Allais's monumental work, 'The Anisotropy of 
Space', is starting! At the moment, an electronic version 
of Chapter 1 is available at  

https://www.amazon.com/dp/B07B9YMNK1/

and a paperback version with the same text and images is
available at

https://www.amazon.com/dp/1980514623/

This Chapter 1 constitutes about a quarter of the entire 
book. It gives a long and detailed description of Allais's 
six marathon non-stop series of experiments with his 
paraconical pendulum with anisotropic support, each of 
those series being about one month long, along with 
detailed statistical analysis of the results. Such a 
dedicated long-term experimental effort has never been 
performed before or since; I think that only Miller's four 
series with his interferometer in 1925-26 can compare.  

Various people may have different opinions about the 
meaning and even the validity of Allais's pendulum work, 
but it is incontestable that his book is unrivaled as a 
human document that bears witness to the indefatigability 
and persistence of the experimenter.  

Chapter 2, which is shorter, will appear later. It 
describes Allais's experiments using a paraconical pendulum 
with isotropic support, which were cut short in 1960 by a 
brutal interruption of funding.  

You don't need to own an actual Kindle device to get this 
book in electronic format. You can download a free app from 
Amazon, and then your computer will mimic the operation of 
a physical Kindle, and you can download books to it in just 
the same way.  

Or, of course, you could buy the physical paperback.

What do you do when your dream dies?
Dreams die in every life. But not Pham's 
dream. He had pursued it across five hundred 
light years and three thousand years of 
objective time. It was a dream of a single 
Humankind, where justice would not be 
occasional flickering light, but a steady glow 
across all of Human Space. He dreamed of 
a civilization where continents never 
burned, and where minor kings didn't give 
children away as hostages.
