Bird songs and bird calls are a reminder that nature is always around us, even when we might think that we are far from it. The earliest known conception of mathematical infinity appears in the Yajur Veda, an ancient Indian script, which at one point states, "If you remove a part from infinity or add a part to infinity, still what remains is infinity." Infinity was a popular topic of philosophical study among the Jain mathematicians c. 400BC. They distinguished between five types of infinity: infinite in one and two directions, infinite in area, infinite everywhere, and infinite perpetually. The symbol ∞ {\displaystyle {\text{∞}}} is often used to represent an infinite quantity. The 25 Spirit Animals & the Amazing Meanings Behind Them All. https://educateinspirechange.org/25-spirit-animals-amazing-meanings-behind/During the 600s, negative numbers were in use in India to represent debts. Diophantus' previous reference was discussed more explicitly by Indian mathematician Brahmagupta, in Brāhmasphuṭasiddhānta in 628, who used negative numbers to produce the general form quadratic formula that remains in use today. However, in the 12thcentury in India, Bhaskara gives negative roots for quadratic equations but says the negative value "is in this case not to be taken, for it is inadequate; people do not approve of negative roots". This is why no planets up till now have shown any evidence of life as their environment does not support the growth of nature.

The use of 0 as a number should be distinguished from its use as a placeholder numeral in place-value systems. Many ancient texts used0. Babylonian and Egyptian texts used it. Egyptians used the word nfr to denote zerobalance in double entry accounting. Indian texts used a Sanskrit word Shunye or shunya to refer to the concept of void. In mathematics texts this word often refers to the number zero. [15] In a similar vein, Pāṇini (5th century BC) used the null (zero) operator in the Ashtadhyayi, an early example of an algebraic grammar for the Sanskrit language (also see Pingala). By 130 AD, Ptolemy, influenced by Hipparchus and the Babylonians, was using a symbol for0 (a small circle with a long overbar) within a sexagesimal numeral system otherwise using alphabetic Greek numerals. Because it was used alone, not as just a placeholder, this Hellenistic zero was the first documented use of a true zero in the Old World. In later Byzantine manuscripts of his Syntaxis Mathematica ( Almagest), the Hellenistic zero had morphed into the Greek letter Omicron (otherwise meaning70).in the case when both a and b are negative even bedeviled Euler. [31] This difficulty eventually led him to the convention of using the special symbol i in place of − 1 {\displaystyle {\sqrt {-1}}} to guard against this mistake.

The earliest fleeting reference to square roots of negative numbers occurred in the work of the mathematician and inventor Heron of Alexandria in the 1st century AD, when he considered the volume of an impossible frustum of a pyramid. They became more prominent when in the 16thcentury closed formulas for the roots of third and fourth degree polynomials were discovered by Italian mathematicians such as Niccolò Fontana Tartaglia and Gerolamo Cardano. It was soon realized that these formulas, even if one was only interested in real solutions, sometimes required the manipulation of square roots of negative numbers. The search for roots of quintic and higher degree equations was an important development, the Abel–Ruffini theorem ( Ruffini 1799, Abel 1824) showed that they could not be solved by radicals (formulas involving only arithmetical operations and roots). Hence it was necessary to consider the wider set of algebraic numbers (all solutions to polynomial equations). Galois (1832) linked polynomial equations to group theory giving rise to the field of Galois theory. The first known documented use of zero dates to AD 628, and appeared in the Brāhmasphuṭasiddhānta, the main work of the Indian mathematician Brahmagupta. He treated0 as a number and discussed operations involving it, including division. By this time (the 7thcentury) the concept had clearly reached Cambodia as Khmer numerals, and documentation shows the idea later spreading to China and the Islamic world. Perhaps the greatest symbol of nature is us, mankind itself. Nature is key to our survival and where there is no nature and just dead, barren land, it will be hard to find life either.

The late Olmec people of south-central Mexico began to use a symbol for zero, a shell glyph, in the New World, possibly by the 4th century BC but certainly by 40BC, which became an integral part of Maya numerals and the Maya calendar. Maya arithmetic used base4 and base5 written as base20. George I. Sánchez in 1961 reported a base4, base5 "finger" abacus. [16] [ bettersourceneeded] Another true zero was used in tables alongside Roman numerals by 525 (first known use by Dionysius Exiguus), but as a word, nulla meaning nothing, not as a symbol. When division produced0 as a remainder, nihil, also meaning nothing, was used. These medieval zeros were used by all future medieval computists (calculators of Easter). An isolated use of their initial, N, was used in a table of Roman numerals by Bede or a colleague about 725, a true zero symbol. You can hear them right as the day breaks every single day, and feel yourself getting relaxed as you absorb those bird songs and chirps in your mind. Final Thoughts There are other uses of zero before Brahmagupta, though the documentation is not as complete as it is in the Brāhmasphuṭasiddhānta.
