This informative book covers the pre war period to the 1990s spanning the author s experience of the rise of Nazism on the continent, his research and his involvement in the planning of Science and Higher Education in Britain. He gives a wry commentary on education and science in Britain, and describes his role in pressing for adequate funding for science, especially during the Thatcher era. His research in Edinburgh with the future Nobel Laureate Max Born, one of the giants of Theoretical Physics, led to a breakthrough in solidstate physics. In Manchester he worked with Patrick Blackett, also a future Nobel Laureate, measuring Extensive Air Showers . These are sprays of particles, which fall on the earth generated by nuclear particles from the cosmos. Later in Leeds he was one of the initiators of the National British Air Shower Experiment. He writes about some of the famous scientists he has met, and also of his disappointments which are often the fate of a working scientist. This is not a rounded autobiography. Much of the book is concerned with Kellermann s research in solid state and cosmic ray physics and his interaction with outstanding physicists of the time, notably his work with Karl Przibram in Vienna and later with Max Born, Patrick Blackett and E C Stoner, and his meetings with C F Powell in Great Britain. There is also an account of his meeting with Max Planck, his discussions with the later atom spy Klaus Fuchs and other notable scientists of the period. It is concerned also with British science policy and Kellermann s commitment to promote support for science by British governments of the day. But a life in physics spanning the second half of the twentieth century is also likely to be a life deeply marked by warfare, antiSemitism, and disruption. These intelligently written memoirs (Professor Geoffrey Cantor, University of Leeds) offer perceptive assessments of contemporary events and of many of the scientists and politicians Kellermann encountered. The Leitmotiv during Kellermannss later years was his research on cosmic ray extensive air showers. The nonspecialist will find a clear account of how these showers, caused by enormously energetic particles from the cosmos are clues to its understanding, an account leading right up to the present state of the art.

Abrir a Caixa de pandora significa mostrar uma maneira diferente de interpretar a Bíblia no sentido "Ufológico". Para tal feito abrir a Caixa pode nos trazer premissas positivas ou negativas quando deparamos com Instituiçes religiosas ou Pseudo-Crists. Chegamos ao futuro e a tecnologia onde os vestigios do passado começam a invocar a nossa mente presente de que os "Indios Playboys Judeus" certamente foram visitados por raças extraterrestres e no so foram ajudados como tambem herdaram os seus costumes, deixando um grande legado a humanidade. Chegou a hora de parar de classificar que um "Deus Todo Poderoso" foi responsavel por toda a Biblia Sagrada e que "Mentores" de religies ignorem estes verdadeiros e afiados fatos. Na historia universal, encontramos milhares de relatos que nos falam sobre os UFOs no decorrer dos milenios, tanto no testemunho das pessoas em seus simples relatos que vai ate de um risco no cho a pinturas famosas de seculos passados, vimos a presença UFOs na arqueologia que tenta se confundir e no dar respostas concretas ou no sabem explicar o que seria aquilo . No entanto, apesar de se fazerem presentes na historia de todos, muitos no acreditam na sua existencia. E se assim o fazem e porque querem ainda considera-los como oriundos do ceu,como um fator divino. No quero dizer com isso que Deus e astronauta, pelo contrario, queremos dizer que Deus e o criador de tudo que existe e que ele no precisaria de naves para vir ao nosso planeta. Para mim ja no sera espanto quando chegarem naves extraterrestres onde o seus tripulantes estaro vestidos e com caracteres como os Sacerdotes judeus antigos (Kohanim). No existe duvida que a India, China, e Japo ja foram visitados por seres celestes, que tentaram passar um pouco do que eles aprenderam neste mural do universo . Tenho a certeza de que este mundo na qual possui varios tipos de raça, e na verdade um celeiro de extraterrestres que vieram ate a nos e tentaram fundir a suas raças geneticamente, porem no obtiveram muito sucesso, o que restou foi apenas vestigios. E tambem no tenho duvida do que os *Greys tiveram um fator importante na qual estes seres ou talvez com outros apoiaram firmemente o Reino Egipcio, e 68 tambem de que eles travaram guerra com os seres que se identificavam serem pertencente a YHWH , na qual consta nas escrituras Biblicas. Sei que os *Greys sero uma total ameaça aos seres humanos no futuro proximo, e de que um grande evento podera acontecer em nosso planeta. Quero ainda declarar que o caso de UFOs e um fato mundial, e que as autoridades, no sabemos por quais motivos... Tentam esconder relatos como estes de toda populaço, como aconteceu com o caso de Varginha. ( tambem no podemos afirmar se isto e verdadeiro, uma vez que no tenhamos provas cabiveis, apenas testemunhais) No meu entender, tais criaturas (extraterrestres) para o sistema global e a suas autoridades isto causariam um caos mundial, um pandemonio poderia acontecer. Mais sei que ainda estes fatores um dia, se no for por mim, sera quebrado por outro a chave do grande misterio da humanidade sera revelado, e tenho certeza que quando houver esta iluminaço estaremos libertos de tudo e a paz reinara neste mundo de caos, governos corruptos, sistema politico sujo, mundo que se encontra em trevas, mesmo que tenhamos religies na terra.
