Who Discovered Zero?
Transcript of Who Discovered Zero?
They had sexagismal
instead of a
decimal system. Babylonians In around 500 AD ‘’Arybhatta’’ created a positional number system without zero.
He used ‘’kha’’ for position which also became the name of zero later.
A Dot (.) was used as an empty place holder. India The Mayans had a system around 665 AD
that used place value system with base 20
and a symbol for
an actual zero. Mayans The Greeks did not have a positional number system as mathematicians solved thing geometrically such as ‘’Euclid ‘’.
Only merchants used number
for keeping records. Greece Indians idea spread to china and Islamic countries .
In 1247 Chin chiu-shao wrote mathematical treatise in nine sections which used zero and in 1303 zhu shijie used an O in jade mirror of the four elements. China
the Indian numbers
Zero was not accepted
widely until the 1600’s. Italy By: Hero M. Salh The phenomenon of Focus Of Presentation Geographical history of zero.
Uses of Zero.
Zero as the name.
Fear of zero.
Properties of zero.
What if there was no zero.
Italy Geographical history of zero Zero was independently invented only three times. Two uses for zero, both extremely important
1- Empty place indicator ( 2106 clearly different from 216).
2- The number itself, in the form we use it as 0. Uses of Zero
The Arabs turned the Indian name for zero, Sunya (void)to sifr, and the west(Fibonacci) turned sifr into Zephirum, from which also gives the name ‘’cipher and zeron'' which our words cipher and zero arose. Zero as the name
The Greeks and Romans refused to convert to Babylonians system.
The zero-less world created by Pythagoras, Aristotle, and Ptolemy.
That fear resisted zero for 2000 years, and caused growth math to stop, block scientific development, and made error
in the calendar. Fear of zero Brahmagupta attempted to give rules to arithmetic involving zero:
9-0=9 Properties of zero Bhaskara found that a number divided by zero is infinity (a/0=∞)
He also discovered 0^2 is 0
And sqrt of zero is zero. 500 years after Brahmagupta Without zero:
There would be no negative number
No computer science
But the most Important things,
NO MATHEMATICS What if there were no zero??
Zero is possibly one of the most important discoveries of all times.
The world would not function correctly without zero. Conclusion Cajori .F. “A history of mathematics,” Chelsea publishing company New York, 1991, page 119
