In fact, this ubiquitous symbol for “nothing” didn’t even find its way to Europe until as late as the 12th century. It might seem like an obvious piece of any numerical system, but the zero is a surprisingly recent development in human history.

It’s this dot that will later evolve to be the symbol with a hole in the middle that we know today. In India, zero was theorized in the seventh century by the mathematician Brahmagupta.

The zero-length launch system or zero-length take-off system (ZLL, ZLTO, ZEL, ZELL) was a method whereby jet fighters and attack aircraft could be near-vertically launched using rocket motors to rapidly gain speed and altitude. Firstly it came into existence independently as a symbol in the Hindu-Arabic number system with a base 10.

From India, the zero made its way to China and back to the Middle East, where it was taken up by the mathematician Mohammed ibn-Musa al-Khowarizmi around 773. “Some of these ideas that we take for granted had to be dreamt up. Some places and countries did not know about zero, which may have made it harder for those people to do mathematics.For example, the year after 1 BC is AD 1 (there is no year zero). �*8UbB�JM�,bx H'���4)��K#̈́5" �j5��.T2m' L����"P�FR- Across the text there are hundreds of zeros denoted using a dot. ,�Qvb$�`���:�c��6��Ȏ$������{�E�5g��]��xG�VRG��Ib������!�%��n���q����^�b1t~E�&%ǩpj'��oƠ���Q2��� �`�%9Bn� j~'��Y�@�|��)eဲ?

But only the Indian dot that would eventually go on to gain true number status, first described in 628 AD by the Indian astronomer and mathematician Brahmagupta. Now, for the first time, the manuscript has been carbon dated – and this has immediately upturned some commonly held beliefs.

It was al-Khowarizmi who first synthesized Indian arithmetic and showed how the zero could function in algebraic equations, and by the ninth century the zero had entered the Arabic numeral system in a form resembling the oval shape we use today.
