J10: Behavior of Massive Particles Near the Velocity of Light
Work done at:
UNIVERSITY OF KARACHI, University Road, Karachi 75270,

Kamal SA, Husain SA, Karachi University Journal of Science, 17 (1&2),
1989, 111-120
Behavior of massive particles near the velocity of light was discussed. It was
shown that an accurate determination of velocity makes the Lorentz factor
and the energy indeterminate. The relativistic relation of mass was modified
so that mass was non-infinite at v = c in the light of uncertainty principle.
An experiment was proposed to test the theory.

J09: Basic Requirements to Train a Physicist
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan 
Kamal SA, Siddiqui KA, Physics Education (India), 6 (1), 1989, pp 53-61 — April-June issue
Since the future progress of Pakistan depends on an adequate training of physicists, we need to prepare them
for careers in industry, research and teaching. They should have a thorough understanding of the basic principles of physics and must be able to apply them in practical situations. Our curriculum should prepare them to handle standard texts in electrodynamics, classical mechanics, statistical physics, quantum mechanics and applied mathematics. To achieve this goal the students need to be highly motivated and should develop habits of creative thinking and critical analysis. A curriculum was proposed for BS, MS and PhD in physics, suitable for the needs of Pakistan. This curriculum, also, prepared students for graduate and postgraduate studies in foreign universities.

J08: Spacetime Representation of Global-Electrocortical Activity
Work done at:
UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Siddiqui KA, Husain SA, Biological Cybernetics, 60 (4), 1989, 307-309
A model for global electrocortical activity is developed by considering telencephalonic structures as mass of
linked oscillators generating activity with a number of resonant modes. Equations for the signals are written in
the comoving frame and then transformed into the laboratory frame. The state transition matrix is obtained in
the presence of electric and magnetic fields.

J07: A Dimensionless-Reciprocal Lattice
Work done at:
UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Husain SA, Karachi University Journal of Science, 16 (1&2), 1988, 23-27
The reciprocal-lattice vectors, widely, used in solid-state physics have dimensions of inverse of length and,
hence, are going to be different if systems of units are changed. A modified lattice, cross lattice, was defined in such a way that the cross-lattice vectors were independent of the coördinate system chosen. Angular-momentum eigenfunctions for cross lattice were, also, obtained.

J06: The Direction of Qibla (Makka)
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Science and Technology in the Islamic World, 5 (3), 1987, 131-134
A mathematical derivation of the direction of qibla (the holy structure in Makka Mukarramah, Kingdom of Saudi Arabia, whose center is taken as reference direction toward which all Muslims face while saying their prayers) as  based on the geodesic was given for any point on the surface pf earth. This should help to resolve the controversy regarding the qibla direction in North America.

J05: Relationship of Anthropometric Measurements Taken on Clothing to Those Taken on Body
Work done at: THE JOHNS HOPKINS UNIVERSITY, Homewood Campus, Baltimore, Maryland 21218, United States
Kamal SA, Karachi University Journal of Science, 14 (1&2), 1986, 35-39
Anthropometric measurements are of fundamental importance in school health care. Sometimes, it is not practical to take the measurements on body. In these circumstances, the measurements are taken on clothing. This paper introduced relations to convert girths (circumferences) taken on clothing to those taken on body.

J04: Measurement of Angle of Spinal Curvature by Moiré Topographs
Work done at:
UNIVERSITY OF OKLAHOMA, Norman, Oklahoma 73019, United States
Kamal SA, Journal of Islamic Medical Association (United States), 14 (4), 1982, 145-149
A method for the measurement of angle of spinal curvature from moiré topographs for scoliosis and kyphosis was described. The angles measured in this way were compared with the angles measured from X rays by Cobb’s method.

J03: Determinant of a General Tensor
Work done at:
INDIANA UNIVERSITY, Bloomington, Indiana 4705, United States
Kamal SA, Matrix and Tensor Quarterly (UK), 31 (3), 1981, 64-66; abstract published in Mathematical Reviews 82j, October 1982, 15025 (15: Linear and Multilinear Algebra: Matrix Theory), published by the American Mathematical Society
A generalized definition of a determinant of mth rank was proposed. Two theorems were given with proofs, viz., the determinant of an inner product is equal to the determinant of an outer product, and, the determinants of a general tensor form an abelian group under the operation of multiplication.

J02: Extended Symmetries in Special Theory of Relativity
Work done at: INDIANA UNIVERSITY, Bloomington, Indiana 47405, United States
Kamal SA, Chinese Journal of Physics, 19 (4), 1981, 87-91
The behavior of particles with velocities greater than the velocity of light was re-examined and a theory presented, which was based on the symmetry principles of nature.

J01: Physical Significance and Properties of Relativistic-Effective-Mass Operator
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Journal of Natural Sciences and Mathematics, 20 (1), 1980, 15-22; abstract published in Mathematical Reviews 81h, August 1981, 81210 (81M: Relativistic Theory), published by the American Mathematical Society
Physical significance and properties of the relativistic-effective-mass operator (REMO) were discussed. REMO for tachyons (faster-than-light particles) was defined and its properties were compared with REMO for bradyons (slower-than-light particles).

The Students’ Gazette (April-May 1987) interviewed Syed Arif Kamal about his views regarding Department of Physics, University of Karachi. The interview was conducted by Nadia Mufti, BSc (Hons), First Year, Department of Physics.

What condition was this department in, when you joined? And how has it changed ever since?

Things have improved since the earlier times. We have more facilities and opportunities now.

Do you think the lab equipment provided to the students is enough?

We have tried to accommodate every student with individual apparatus. However, still, due to a large number of students there are, sometimes, more people on one apparatus.

Do you face any problems or difficulties with your students?

As such, there are no difficulties, but the classes are too overloaded due to which personal attention cannot be given to each student in class.

This science requires so much time and study. Is it all worth it when the time comes to find a job?

There is no shortage of jobs as people think, especially in the field of Physics. What is required is commitment. A degree doesn’t assure employment, initiative is needed as well.

Is there any future for Physics in Pakistan?

As I said before, scope is a man-made thing. If we show interest and commitment, we can brighten the future. There is no lack of talent in this country, only a clear concept is needed.
