: His technical expertise lies in instrumentation engineering and the study of fracture toughness in brittle materials like ceramics and polymers. One of his primary projects involved developing methods to control and analyze stable crack growth. Pyramid Research & Theories
: He developed the "P4" computer program to perform the complex astronomical calculations required to support his planetary correlation theories. Other Interests Hans Jelitto
: He served as a Research Associate (now retired) at the Hamburg University of Technology (TUHH) , specifically within the Institute of Advanced Ceramics. Other Interests : He served as a Research
: He authored the book Pyramiden und Planeten ("Pyramids and Planets"), where he proposes that the arrangement of the Giza pyramids in Egypt corresponds to the orbital positions of the inner planets (Mercury, Venus, and Earth) at a specific point in time. Hans Jelitto
