Suppose
one has learnt quite a bit of high-school/junior college physics, meaning he
knows all about things like Newton’s laws and equations of motion, Archimedes’
principle and Pascal’s law and equations that govern the behaviour of mirrors
and lenses, and the propagation of sound, and the basics of thermodynamics and
electromagnetism and even the way atoms are supposed to be built and to behave
– is that knowledge enough to understand all there is to chemistry? Any modern chemist would say no, while acknowledging
that much of his domain overlaps with the physicist’s territory: still, you
cannot pronounce on the way acids and bases interact to form an enormous
variety of salts on the basis of the laws of physics alone, nor how organic
compounds transmute from one category to another under the influence of
specific chemicals, temperatures, pressures and catalysts, nor how very large
compounds, such as amino acids and proteins, can be synthesized and modified. That is why a separate subject called
chemistry still exists, and shows no imminent signs of dying out.
When
you move on to the study of life –
from the composition, structure and organization of individual cells to the
specific study of the character and behaviour of tissues and organs and complex
organ systems, meaning particular living species, and given that there are
uncounted millions of incredibly different living species on earth from
bacteria and diatoms to giant trees and whales and homo sapiens itself, it goes
without saying that, though physics is still believed to be the most rigorous,
determinate, fundamental Queen of the Sciences, and the study of modern biology
is sought to be grounded in a good understanding of physics and chemistry, no
biologist or medical researcher will dream of asserting that a good grasp of
physics or even chemistry alone will equip you to understand life and its
infinite variety and complexity: however unsatisfactorily descriptive, non-rigorous,
non-mathematical the biological sciences are, they still exist in their own right, and will continue to do so for
the foreseeable future. A ‘Theory of Everything’, that elusive Holy Grail of
physics, even if attained someday, will not take you very far in becoming a
good student of evolution or a competent doctor. It is wise to keep this in
mind, despite the fact that most physicists sneer at the ‘lesser sciences’.
Our
doctors, though they are (for most of the time) dealing with only our bodies –
the material part of ourselves, hence most accessible to science as we
understand it – are most of the time acutely aware, moreover, that we have
something called minds (many biologists would claim that so do many other
animals, like elephants, dolphins, chimps, pigs and horses, though admittedly
of a far less complex and less multitalented sort), and the mind, though
centred in the brain but spread throughout the body via the senses and an
unthinkably complicated network of neuro-chemical connections, is so
inextricably intertwined with everything the body does and feels that it is
almost impossible to treat any really serious malaise, from accident-related
trauma to heart disease, without involving the mind in the process. And the
mind (as Yudhishthir averred two millennia ago and Asimov concurred a few
decades ago, the single most complex piece of organized matter in the universe),
still for the most part defies comprehension and conscious, rational control,
though the cleverest of men having been trying to understand it for thousands
of years. Psychology studies it most directly (alongwith, lately, neuroscience,
using fMRI brain scanners), but so have all religions (and their insights are
not to be ignorantly scoffed at). From what I have read of history, sociology,
economics and politics, they are all diverse ways of studying the same thing,
and after millennia of effort, no expert in any one of these fields can claim to have anything more than a partial
picture, each often having special techniques of distorting and caricaturing
the reality in its effort ot make it manageable and comprehensible (economics,
especially of the mathematical variety, would fall flat unless it assumes the
pathetic hyper-simplification that Man is nothing
but a machine coldly calculating pleasure, pain, profit and loss all the
time). That should give us some idea of how complicated the subject matter is.
Literature (including, very importantly, biographies) and cinema, moreover, are
very powerful ways of not only trying to understand
the human mind but to explore its seemingly limitless creative powers. As the
Bard said, ‘What a piece of work is Man!’, he himself being a prime exemplar.
It
is with this mind that we compose Thus
Spake Zarathustra, and sculpt Madonnas, and write Hamlet, and work out e equals m times c squared, and love and hate
and laugh and learn and dream. It is with this mind that I long for God (who is
this ‘I’? Is it an illusion? Does it mean
anything? Where is it located? Is it coterminous with the body and bodily
life? Why are some few minds so immeasurably more powerful than the rest? Do
collective minds exist?...). It is this I
which is reflecting while writing this essay…
The
long and short of it is, even a fairly good grasp of the fundamental sciences,
physics and chemistry, gives you little or no understanding of what is, or
should be, the most important thing of interest to all of us, that which,
individually as well as collectively, shapes and guides our destiny.
If
this is accepted to be true, isn’t it a frightening thing that of late those
who are guiding the fates of nations, heads of governments and CEOs of giant
corporations, have very little education outside of one or the other of the
sciences?
Don’t
we need much more broadly educated people at the helm of affairs than we have
right now? And doesn’t that beg the question, what does being ‘educated’ mean?
Just
thinking. Swarnava, it is budding physicists like you who give me the courage
to wonder publicly like this, those who, despite loving their own subjects,
already know that ‘this is not all there is’. Who know and respect and wonder
over the fact that some of the greatest insights in science, too, come in
dreams…
