In mathematics, infinity is the conceptual expression of such a numberless number. It is often symbolized by the lemniscate (also known as the lemniscate of Bernoulli), which looks something like the numeral 8 written sideways (). This symbol for infinity was first used in the 1600s by the mathematician John Wallis.
An epic is a poem; most epics started as oral tales that were passed down from generation to generation (often in the form of songs), which is why they're poems. A legend and a myth are more similar, but a myth most often explains something about the universe. So while there might be a legend about a man who slayed all the dragons, a myth would be about the man who caused it to rain, or how humans were created. Those are the basics differences.
Many people consider folktales and fables as part of the same body of tales which forms the oral and written heritage of a culture. They often tend to deal with similar fantastical subjects, and often both have moral lessons. However, despite these similarities, there are some differences between the two types of story.ifferences in Authorship. The other key difference between folktales and fables is authorship. A story is only really a folktale if it belongs to a traditional body of stories, told and retold in a variety of ways among a society.
