nvented the infinity symbol?

Question

a mathematician

Answer 1

Michael T is right

Answer 2

The precise origins of the infinity symbol ∞ are unclear. One possibility is suggested by the name it is sometimes called — the lemniscate, from the Latin lemniscus, meaning "ribbon". One can imagine walking forever along a simple loop formed from a ribbon.

A popular explanation is that the infinity symbol is derived from the shape of a Möbius strip. Again, one can imagine walking along its surface forever. However, this explanation is improbable, since the symbol had been in use to represent infinity for over two hundred years before August Ferdinand Möbius and Johann Benedict Listing discovered the Möbius strip in 1858.

It is also possible that it is inspired by older religious/alchemical symbolism. For instance, it has been found in Tibetan rock carvings, and the ouroboros, or infinity snake, is often depicted in this shape. In the tarot, the lemniscate represents the balance of forces and is often associated with the magician card.

John Wallis is usually credited with introducing ∞ as a symbol for infinity in 1655 in his De sectionibus conicis. One conjecture about why he chose this symbol is that he derived it from a Roman numeral for 1000 that was in turn derived from the Etruscan numeral for 1000, which looked somewhat like CIƆ and was sometimes used to mean "many". Another conjecture is that he derived it from the Greek letter ω (omega), the last letter in the Greek alphabet.

Answer 4

Infinity. The infinity symbol was introduced by John Wallis (1616-1703) in 1655 in his De sectionibus conicis (On Conic Sections)

Answer 5

The first known recorded sign was around 250 B.C. It isn't known what the meaning of the symbol is but the early Romans were the first to use it as the "Infinity" symbol. And it was a preist who used it as a symbol of God's undying love.

Answer 6

Must be some mathematician, as you already know. Then why ask instead of searching yourself ?

Answer 7

if you look at the symbol, the two circles are connected. oo.if you look at each circle as an entity, and the two intities are connected, this represents how we all are connected by love; which has no end.
