...scientists that honored the late Max Planck's 100th birth date, German Physicist Werner Heisenberg, 56, reported that he is prepared to make "a suggestion for the basic equation of matter." In Manhattan, before a meeting of the New York Academy of Sciences, German-born Dr. John Grebe, 58, director of Dow Chemical Co.'s nuclear, research, proposed "a periodic table for fundamental particles" that might help "explain the material of the universe...

Ultrasimplicity. U.S. physicists who have seen Heisenberg's equation still feel that it cannot quite explain all they see in their accelerators. Dr. John Grebe (rhymes with Hebe) begins with what they do see. A noted industrial researcher who was a leader in the wartime development of styrene for synthetic rubber, Grebe nevertheless has the same classical approach as Heisenberg. The secret of why the fundamental particles of matter somehow hold together in the atomic nucleus, he feels, must be less complicated than researchers believe. Reason: the rest of nature is "so beautiful and orderly and ultrasimple...

Working with what is known about the 28 accelerator-produced new particles, Grebe theorizes that they may all be multiples or combinations of only two: pairs of the negatively charged electron and the positively charged electron (positron). Reason is his discovery of two key particle ratios: that between the mass of mu and pi mesons, and that between the mass of the proton and sigma hyperon. Each proves to equal TT divided by four; this produces a new constant (1.12888), based on the inverse of the square root of TT divided by four, which Grebe calls "g." This tool "opens...

Other men have unsuccessfully focused on the electron and positron as the atom's "building blocks." Grebe hopes his table may have turned the trick. For it would, he suggests, indicate that gravity itself is an electromagnetic force accountable in electromagnetic terms. Like many another, this "unified field theory" may also fail. But, says Grebe, "the mathematical relations discovered cannot help but remain and be a useful step forward...
