MENSA, the elite international high-IQ society, was founded in Oxford during 1946 as a third pillar intended to complement the Royal Society and British Academy. There is but one single requirement to be invited to join MENSA: an individual must have an IQ that is measured to be among the top two per cent of the population. But what is MENSA, and what purpose does it serve? The purpose of this book is to critically examine this 'origin myth' of Mensa in light of evidence from publicly accessible primary sources. Of particular interest is the stated aim of MENSA's three acclaimed founders for the society to conduct research that would or could inform decision-making by government and other authorities. These two books were written by 'an insider' who has been a member of MENSA for some 30 years and the goal is to reveal some very interesting aspects of this global organisation. This book first traces the history and development of MENSA and then critically examines some of the research conducted on or by members of MENSA over the last seventy years. The third chapter then provides evidence for three experiments designed to test the nature of light: (i) a series of table-top experiments to test the wave-particle nature of light and Einstein's relativistic theories and which challenge both; (ii) a split light beam experiment to illustrate 'the Q signal' which is arguably a precursor to photon entanglement; and (iii) an experiment to test the ability of light to travel independently of its source and which could also detect gravity waves and use triangulation to pinpoint the source. This experiment is arguably the precursor to the European Space Agency's forthcoming eLISA experiment. Then a theory to explain the periodic reversal of the Earth's geomagnetic poles is presented and in the fourth chapter recent preliminary research presented that may provide supporting evidence. Two sets of evidence were identified that could prove this theory: (i) evidence that the Sun periodically reverses its own geomagnetic poles, and (ii) geological evidence on other planets in the solar system for magnetic striping similar to that discovered in oceanic crust here on Earth which is thought to provide evidence that the Earth's own geomagnetic poles periodically reversed. Both sets of evidence have been found to exist. In the fifth chapter evidence is put forward in support of the author's claim to be the catalyst for the formation of the European Academy of Sciences. The two Appendices contain further evidence for research, which covers a broad spectrum of research interest and observations.
