| Show magnetic field of the earth still Is mystery of science washington scientists are still searching for a hidden clue or perhaps a new and unknown principle of physics which can explain the large magnetism of the earth and the far vaster magnetism of the sun said dr M A tuve of the department part ment of terrestrial magnetism of carnegie institution in an address here for ten years the department under the leadership of dr J A fleming has searched tor for the answer to the baffling question whose solution would make clearer the role played by the earths magnetic field in mans daily we life a role which affects radio wire communication muni cation cosmic ray intensity the amount of ultraviolet light striking the earth and many other factors in mans existence on their 10 year research march toward this goal doctor tuve and his colleagues dr L R hafstad and dr N P heydenburg of the department and prot prof gregory breit of wisconsin university have uri uncovered covered new and important findings but most fundamental of all was the detection and measurement of the enormous force within the cores of atoms that binds their parts together and prevents the universe from consisting of nothing but the nuclei of the simplest atom hydrogen no clue yet discovered thus the program which began and still seeks explanations of earth and solar magnetism has led into the hearts of the tiniest things in the universe but neither the tremendous force there discovered nor any other tact fact of modem physics has yet led to a clue which might explain the permanent magnetism of the earth doctor tuve told his audience to explain these large magnetic fields in the sun and earth it appears that either some new complexity will have to be introduced into the fundamental concepts of physics or that some new and yet unfound principle of physics will have to be discovered the first view seems the more probable doctor tuve indicated however some unknown atomic force occurring at the extremely high pressures within the earth and the sun may be the cause of the large magnetic fields said he the nuclei between which ahe new force of attraction has been found to exist are so minute he added that if one of them were enlarged to a diameter of one half inch the fingers and thumbs of the investigators on the same scale would be approximately miles long |
