Musa Daji Abdullahi (born 19 July 1941) is a Nigerian electrical engineer and independent researcher known for his work on an alternative electrodynamics in which a charged particle is accelerated by an electric field to the speed of light with constant mass. His research interests span electromagnetic fields and radiation, electrodynamics, special and general relativity, gravitation and ether theory. His ideas lie outside the mainstream of modern physics.
Biography
Abdullahi was born in Katsina, Nigeria, in 1941. He attended primary school in Katsina from 1948 to 1954 and Barewa College, Zaria, from 1954 to 1959. He studied at the University of Manchester, England, from 1961 to 1965, obtaining a Bachelor of Science degree in physics in 1965. He later earned a Master's degree in electronics and telecommunications from Ahmadu Bello University, Zaria, in 1968.
Abdullahi entered the Nigerian Public Service in 1965, holding a number of teaching and administrative posts. He retired in August 2000 as Director of Engineering Services in the Federal Ministry of Works and Housing. He subsequently taught at Ahmadu Bello University, Zaria, and served on contract appointment as a senior lecturer in telecommunications engineering at the Federal University of Technology, Minna. He later worked as an independent researcher and adjunct lecturer in the Department of Physics at Umaru Musa Yar'adua University, Katsina.
Scientific contributions
Abdullahi is an independent researcher who has developed what he terms an alternative or "radiative" electrodynamics. In this framework, a charged particle such as an electron can be accelerated by an electric field to the speed of light as a limiting value while retaining a constant mass, accompanied by the emission of radiation. This stands in contrast to the theory of special relativity, in which a particle's mass is held to increase without bound as its speed approaches that of light.
In Abdullahi's model, it is not the mass of the particle that changes with speed, but the accelerating force acting on the charged particle, which he proposes falls to zero as the particle reaches the speed of light. He expresses the accelerating force on an electron as F = eE(c − v)/c = m(dv/dt), where m is a constant mass and c is the speed of light. The difference between this force and the force on a stationary electron is interpreted as a radiation-reaction force, against which the work done appears as emitted radiation. He has argued that at low speeds his formulation and relativistic electrodynamics both reduce to classical electrodynamics, but that they diverge at speeds close to that of light.
Abdullahi has also extended these ideas to propose explanations of inertia and gravitation outside the framework of general relativity. His work has been presented at conferences and published in independent and open-access venues rather than in the mainstream peer-reviewed physics literature.
Honors
Abdullahi is a Fellow of the Nigerian Society of Engineers, the Academy of Engineering, and the Institution of Engineering and Technology. In 2005 he was awarded the Nigerian national honour of Member of the Order of the Federal Republic (MFR).
