Some say this number system includes the earliest use of zero.

Khmer numerals from Sambor inscriptions dated to 683 A.D., found in present-day Cambodia. It requires the ability to represent a concept beyond what is perceived,” he writes. “For a brain that has evolved to process sensory stimuli (something), conceiving of empty sets (nothing) as a meaningful category requires high-level abstraction. This represents a profound logical leap, argues neuroscientist Andreas Nieder in a 2016 paper. “When zero is added to a number or subtracted from a number, the number remains unchanged and a number multiplied by zero becomes zero,” he writes. 628, Brahmagupta provides rules for doing calculations with zero that mirror what we understand today. In his mathematical treatise Brahmasphutasiddhanta, written in A.D. Likely the first to make this logical leap was a man named Brahmagupta, a foundational figure in Indian mathematics. It’s a sign that mathematicians there conceived of zero as a unique numerical entity. There, researchers see the first solid evidence of zero, called “sunya” by the Indians, being used in mathematical calculations. This, argues Robert Kaplan in his book The Nothing That Is: A Natural History of Zero, indicates they probably thought of zero as something closer to a punctuation mark between real numbers, rather than a number in and of itself.įor a true appreciation of zero’s place in the number line, we must venture to India. Greek astronomers like Ptolemy made use of a hollow circle when calculating trigonometric figures, often adding a bar or line across the top. Here, we begin to see traces of the modern oval that we use today to represent zero. It turns up in Greece around the fourth century B.C., probably brought back by Alexander the Great after he conquered the Babylonian Empire in 331 B.C. Zero on the Moveįrom Babylon, zero began to spread slowly to other regions of the world. A translated verse in Maya text mourning a fallen leader, reads, in part, “no pyramid, no altar, no earth/cave.” The same shell glyph that stands for zero in their number system appears here in a more abstract sense, signifying nothing. The shell glyph also appears to have been used to indicate the concept of nothing more generally.

The Maya appear to have used several different glyphs for zero, though a shell was most common.

When they needed to show that a column had nothing in it, the Babylonians came up with the idea of simply leaving a space there - nothing in the truest sense. Though the Babylonians used a different number system than we did, they counted in much the same way using positional notation. To write, say, 105, we need to show that there’s nothing in the tens column, something accomplished with a zero today. There’s a five in the ones column, a one in the tens column and a one in the hundreds column.

For us, the number 115 has three columns with place values - ones, tens and hundreds. When counting, they divided their numbers into columns, much as we do today, a concept called positional notation. This is how the Babylonians employed zeros some 4,000 years ago. Scholars think it began with the concept of nothing as a placeholder while counting. The discovery of zero doesn’t seem to have come all at once, but rather in stages. There, as elsewhere, zero would prove to be a revolutionary concept, inspiring thinkers of the Middle Ages and Renaissance to fundamental insights about mathematics and the world. The concept of nothingness later traveled from the Middle East to India, China and elsewhere.Įuropean civilizations were fairly late to the nothing game, incorporating zero into their cultures only after the mathematician Fibonacci brought the Indo-Arabic numeral system to Europe after travels in the Middle East and Africa. The Maya, likewise, developed the idea of zero independently. The Sumerians are thought to be the first to have recognized the idea of nothing (although not until later did they come up with a symbol for zero). Ancient civilizations found use in zero as well, first as a component of numerical systems and later as a mathematical tool.
