09-04-2014 An Experimental Study for Reproduction of
Biological Anomalies Reported in the 1999 Hoeven Crop Circle

Eltjo H. Haselhoff, Robert J. Boerman, Jan-Willem Bobbink

This article revisits a crop circle that appeared in The Netherlands in 1999. It presents new experimental results in an attempt to find trivial explanations for anomalous biophysical findings reported in relation to this formation. It is concluded that the anomalies cannot be explained as the result of wind, sunlight or the simple fact that the crop was flattened with mechanical tools.

The Joke of the Crop Circle - are crop circle man-made...?
Robert Boerman

This question is the basis of the second crop circle book by Robert Boerman. In 'The Joke of the Crop Circle' the author assumes that all crop circles are made by people. Crop circles are man-made and step-by-step it is explained how can make a crop circle him/herself.

Along the way it becomes clear in the book that some matters can simply not be explained, because what to think of all those biophysical deviations that have been found in crop circles? Deviations that have also been found in wind damage and in a wheat field without circle. And why are crop circles made on leylines and what role do light spheres play? Or do we have to speak off dust particles? Can the growth of wheat be manipulated or does that have something to do with the frequencies that have been measured in crop circles. Does professor Meaden's plasma vortex theory play a role and what does the creation of crop circles have to do with an American invention? Is there a link between both subjects and Haselhoff's light sphere theory?

In 'The Joke of the Crop Circle' several matters are discussed that don't seem to have anything to do with each other at first glance, though by combining them the author has achieved to give a whole new look of the crop circle phenomenon. Are crop circles really works of man like the subtitle of the book suggests or are they created in a different way?

Based on a fourteen year study this book attempts to answer the many questions that have arisen throughout the years. The most important question most probably is: 'Who are the crop circle makers?' The answer can be found in 'The Joke of the Crop Circle'...

05-04-2014 Is Sound Creating...?

It was in 2005 that I started a new research project about 'Cymatics' or 'Water Sound Images' if you want. One of the reasons for this research project was an article which was written by the English crop circle researcher Freddy Silva: 'Is sound creating crop circles...?' Crop circles have caught my interest in 1997 when I discovered a crop circle close to my house during a short flight above our town. Since then I have studied this mysterious phenomenon for many years and have written two books about crop circles.

What on Earth? Inside the Crop Circle Mystery is a feature documentary, shot in England, that features the lively community of visionary artists, scientists, philosophers, geometers, educators and farmers who have been profoundly touched by the crop circle phenomenon. Filled with stunning imagery of the circles, it deals with how our scientific materialistic worldview hampers serious investigations of one of the greatest mysteries of our time. And how ascertaining that the circles come from another intelligence would help us think as a planet, which would give us our best chance to solve the pressing lglobal problems that challenge us now.
