But Fibonacci himself refers to them in his book as the “nine Indian numerals” with zero, which he calls .
Zero is the incredible invention that made our number system so efficient.The zero here is not just a concept of nothingness (and something every schoolchild learns you are forbidden to divide by), but also a .The zero is a sign we place in a location in a number when there is nothing there—to tell us, for example, that 40 means four tens and no units, or that 405 is four hundreds, no tens, and five units. When you stack such rings one on top of the other, and you let them represent, in turn, the units, tens, hundreds, thousands, ten thousands, and so on, based on each ring’s location, you get the highly efficient number system we have today.During the Khmer Rouge era, while killing 1.7 million of their own people, Pol Pot and his henchmen also looted, vandalized or destroyed more than 10,000 ancient statues or inscriptions.The location where the oldest zero in the world—on a seventh-century stone inscription—was kept was plundered by the Khmer Rouge as late as 1990.Its existence thus makes it highly unlikely that the zero was invented in Europe or Arabia and traveled east through Arab traders, as some had believed in the early 20th century.
The Cambodian zero proved that zero was an Eastern invention.
Surprisingly, this clunky old Roman number system, with its ancient Greek and Etruscan roots, remained in use in Europe until the thirteenth century!
Our base-10 system derives its power and efficiency from the fact that we use a zero.
Think of each ring as a dial—when it goes around full circle, you get 0 and you add a 1 to the ring above it.
As an example, start with the number 5—this means only the lowest ring, that of the units, is nonempty, and has the number 5. Five units from the 7 will bring the units ring to 0 and make the tens ring jump up to 1.
Krauss's theory that the universe emerged out of sheer "nothingness," countering the arguments using results from physics, cosmology, and the abstract mathematics of set theory.
