(“Correctly Established Doctrine of Brahma”) by Brahmagupta
is the first known text to describe how to use zero as a number.
It covers addition, subtraction, multiplication, and division with zeros
and whether the result is positive or negative.
Brahmagupta also gave rules
for solutions to general linear equations,
for calculating roots, powers, and sums of powers,
for handling fractions,
for calculating Pythagorean triples,
for calculating the area of cyclic quadrilaterals,
and for the value of π.
Zeros
The Chinese used a space in their counting-rod system
as a placeholder for zero.
The Incans used the absence of a knot
in their knotted cord device.
The Babylonians had a symbol used as a placeholder
in other numbers, to distinguish, for example, 105 from 15.
So did the Olmecs in Mesoamerica
in the numeral system for their long-count calendar.
Ptolemy and the Romans had a symbol for the lack of a quantity,
but they did not perform arithmetic with it.
Mathematicians in India used the the Sanskrit word
“ś ūnya” to refer to zero or void.
For Brahmagupta, zero is a positive number;
today we say it is neither positive nor negative.
For Brahmagupta, a fraction could have a zero denominator;
today we say division by zero is undefined.
Brāhmasphuṭa-siddhānta was translated
into Arabic by 1050.
The Arabic word ŝifr gives us our words
“zero” and “cipher.”
Something
Zero is nothing but nothing itself,
the same as the empty set.
The empty set is a subset
of all other sets,
including the empty set,
which is probably not why
seeing the emptiness in everything
is a key to spiritual enlightenment.
A photon is the zero
of elementary particles;
it’s a mass of nothing
whose energy is all in its frequency.
To reply “empty handed”
is not an empty reply;
it’s better than not replying.
There is only one empty set,
nothing being the same in all circumstances.
Really, no response
is the same as no banana.
Nothing
For the time being,
I enjoy my temporary existence
loving many who are here
and many who are gone,
and it makes me think
how close we are to nothing at all.
We make a distinction between 0, the number of nothing, and
0, a digit that is used in numbers written with digits in our
positional number system.
History shows that the digit 0 came first (using various
symbols). The history of the number 0 came from Brahmagupta. The
Islamic world already had the positional number system.
Brahmagupta gave them the number 0. The Persian, Muḥammad
ibn Mūsā al-Khwārizmī (the inventor of
algebra), oversaw translation of Brahmagupta into Arabic.
Al-Khwārizmī’s work in Latin translation in the
twelfth century introduced the Hindu-Arabic numeral system to the
Western world. Fibonacci, having learned from Arabic
mathematicians, contributed to its adoption in the thirteenth
century.
