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

The equations of straight line are,
generally, given as the intersection of two planes. A systematic way to express
the straightline equations in terms of their direction ratios was presented. Full Text PDF

The NGDS (National Growth and Developmental Standards for the Pakistani
Children) Pilot Project was initiated in 1998 to establish Pakistanbased anthropometricaldata
library and growth charts, to formulate mathematical models, which predict
growth parameters, to write softwares, which generate detailed growth profiles
and to develop inexpensiveanthropometry instruments from local resources, which
could be employed in obtaining anthropometric measurements of Pakistani rural
and slumarea children. Standing and
sitting heights, shoulder widths, weights and midupperarm 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 bodymass 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 310 year old children using
this software. Full Text

J25: The Human Heart as
a System of Standing Waves
Work done at: UNIVERSITY OF KARACHI,

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. Full Text PDF

J24: The Sixth Paradigm of Physics
Work done at: UNIVERSITY OF KARACHI, University Road,
Karachi 75270, Pakistan

(2), 2000, 1116

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. Full Text PDF
J23: The
QuantumMechanical Interpretation of Time
Work done at: UNIVERSITY OF KARACHI, University Road,

28 (1), 2000, 9597

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. Full Text PDF
