A new way to teach math
The word "mathematics" derives from the Greek word
mathesiz, meaning learning.
Hence, mathematics means the "science of learning". According to Plato, "all learning
is recollection", a process by which the soul remembers its eternal ideas. Mathematics
was regarded as best suited to learning since it was believed that mathematics contained
eternal truths which sympathetically moved the eternal soul.
How did it happen that mathematics---once regarded as the science of learning---is
today regarded as the most difficult subject to learn?
Why is math difficult today?
The answer is simple: because religious politics got mixed into mathematics. How?
That is a long story.
For example, in the 5th c., the philosopher Proclus argued that since the truths
of mathematics were eternal, the cosmos itself was eternal. This angered the Christian
priests of the time, who had invented the doctrine of apocalypse: that doomsday
is round the corner (a ploy to frighten people and make them submit to the authority
of the priest). The priests showed their anger by declaring Proclus a heretic,
and in 529, Justinian, the Roman Christian king, banned all schools of philosophy
in the Roman empire.
The full story is interesting (look out for my forthcoming book), but we will not
go deeper into it, since our immediate concern is how to make mathematics easy to learn.
The point is that math was mixed with religion in the earliest Western traditions.
It was for religious reasons that European priests first learnt math in the 12th c. from Arabic books on
math, captured during the Crusades, and translated into Latin, starting 1125. After the failure
of the Crusades, these math books were used to teach Arabic methods of argument to priests,
since the priests (Aquinas and the schoolmen) now aimed to convert Arabs using reason
rather than force. (Of course,
Arabic math books were reinterpreted to make math consistent
with Christian theology.)
It was at this time that Greek authors like "Euclid" were concocted for many of
these books. Ever since then, Western math has suffered from a religious hangover.
In India, however, this religious connection was entirely absent. Mathematics developed
as
ganita: a means of practical calculation. There certainly was a notion
of proof, but this was not the
same notion of mathematical proof as developed
in the West. For example, empirical techniques of mathematical proof were used in
India, although this is disallowed in present-day Western math..
Because of this difference in the understanding of math, Europeans found it
hard to understand Indian math when they first encountered it. Even a simple thing
like the place value for numbers took some five
hundred years to be accepted
in Europe: starting from the recorded blunders made by Gerbert, Pope Sylvester 2
in the 10th c.
Similar difficulties attended the transmission of the calculus from India to Europe.
It took over three centuries from the time of Kepler and Cavalieri, Fermat and Pascal
until the formal real numbers of Dedekind and the eventual formalisation of set
theory in the 20th c.
Education today is unfortunately seen as a process of learning to ape the West, a la Macaulay, so math
is taught from a purely Western perspective. This way of teaching math retraces
the European experience of learning math: so the historical difficulties
experienced by Europeans are replayed in the math classroom.
The solution to this difficulty
is to throw out the religious beliefs that have crept into mathematics, and to go
back to something very close to the original understanding in which things like
the calculus developed as primarily a tool for calculation.
This makes math very simple, and also makes it ideally suited
to the present-day technology of computation which has greatly enhanced the ability to calculate.
Some philosophical adjustments are required in the understanding of math;
but this should not be a serious problem for anyone except those who are currently
regarded as math experts!
