**Infinity** - When did humans first contemplate the concept of infinity? Well the earliest known reference can be found in a section of the *Yajur-Veda* known as the *Isha Upanishad*. It simply reads, "From infinity is born infinity. When infinity is taken out of infinity, only infinity is left over." Whether or not this is a mathematical reference is unclear. If written to denote eternity, then there may be earlier references to this chronological concept found in the Bible. Infinity is clearly referred to as a mathematical value by the Greeks in the 5h century B.C.. The discovery of the value of ** π** is too obscure and will not be speculated on here.
