J28: Concept Building in the Undergraduate Mathema-
ics and Physics Curricula

---------------------------------------------------------
The basic concepts of
scientific method should be reinforced in the undergraduate mathematics and physics curricula. Students should be able to distinguish what is science and what is not science. The key is to keep the terminologies to a minimum and to introduce the correct concepts depending on the cognitive abilities of the students. Experiments need to be designed to demonstrate the concepts taught in the classroom and to inculcate scientific thinking. Full Text PDF

J27: A Systematic Way to Express the Equations of Straight Line in Terms of Their Direction Ratios
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Naseeruddin, Karachi University Journal of Science, 33 (1&2), 2005, 71-72
-----------------------------------------------------------------------------------------------------------
The equations of straight line are, generally, given as the intersection of two planes. A systematic way to express the straight-line equations in terms of their direction ratios was presented.

J26: An Investigation of Growth Profiles of the Pakistani Children
Work done at
: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan

International Journal of Biology and Biotechnology, 1 (4), 2004, 709-717
------------------------------------------------------------------------------------------------------------
The NGDS (National Growth and Developmental Standards for the Pakistani Children) Pilot Project was initiated in 1998 to establish Pakistan-based anthropometrical-data library and growth charts, to formulate mathematical models, which predict growth parameters, to write softwares, which generate detailed growth profiles and to develop inexpensive-anthropometry instruments from local resources, which could be employed in obtaining anthropometric measurements of Pakistani rural and slum-area children.  Standing and sitting heights, shoulder widths, weights and mid-upper-arm circumferences were measured on over 2000 healthy children. Mathematical procedure/software was developed, which takes as input heights and weights of biological parents, and those of child at 2 successive occasions, 6 months apart. The output is a detailed growth profile indicating stunting and wasting (if present), overweight/underweight conditions, height velocity, rate of weight gain/loss and body-mass index (comparison of all three with references). Failure to grow may be the first indication of a major underlying problem. The authors recommend growth monitoring and analysis of all 3-10 year old children using this software.

J25: The Human Heart as a System of Standing Waves
Work done at:
UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Siddiqui KA, Karachi University Journal of Science, 30 (1&2), 2002, 55-63
------------------------------------------------------------------------------------------------------------
The human heart was considered to be a system of standing waves. Acoustic properties of the human heart were modeled by applying the concepts of wave theory. The nature and the origin of various frequencies were considered. Some experimental suggestions were given.

J24: The Sixth Paradigm of Physics
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270, Pakistan
Kamal SA, Siddiqui KA, Naseeruddin, Karachi University Journal of Science, 28 (2), 2000, 11-16
------------------------------------------------------------------------------------------------------------
The present physics is based on a set of five paradigms, namely, the first law of thermodynamics, the second law of thermodynamics, the quantum phenomena, the curved spacetime and the nonlinearity of physical systems. These  paradigms have changed the fundamental concepts of physics about the relationship of space, time and matter. For some time physics seems to be in a static situation. Data keep on flowing without adequate theories to explain them. The time has come for a sixth paradigm of physics to be introduced. This paper formulated the new paradigm in terms of a generalized variational principle.

J23: The Quantum-Mechanical Interpretation of Time
Work done at: UNIVERSITY OF KARACHI, University Road, Karachi 75270,  Pakistan
Kamal SA , Naseeruddin, Karachi University Journal of Science, 28 (1), 2000, 95-97
------------------------------------------------------------------------------------------------------------
If time is substituted in the equation of motion in the Heisenberg picture the results obtained may lead to confusions if the equations are not interpreted correctly. Some examples were given.

Dear Dr. Syed Arif Kamal Saheb,

Assalamu Alaikum! This is to, thankfully, acknowledge the reprint of your paper titled “An Investigation of Growth Profiles of Pakistani children”, published in International Journal of Biology and Biotechnology. This is an honour not only for you but also for the university as well that the research work of a professor from the University of Karachi is being published in a journal of international repute that will encourage you to devote more and more to your research activities.

I wish you more academic achievements in times to come.

With best regards,

Yours sincerely,


Professor Dr. Prizada Q. R. Siddiqui
Vice Chancellor
