Why do we need irrational numbers in real life?
Engineering revolves on designing things for real life and several things like Signal Processing, Force Calculations, Speedometer etc use irrational numbers. Calculus and other mathematical domains that use these irrational numbers are used a lot in real life. Irrational Numbers are used indirectly.
Who is the first man to recognize the existence of irrational numbers?
Hippasus is sometimes credited with the discovery of the existence of irrational numbers, following which he was drowned at sea. Pythagoreans preached that all numbers could be expressed as the ratio of integers, and the discovery of irrational numbers is said to have shocked them.

Irrational numbers can be represented in the decimal form but not in fractions which implies that the irrational numbers cannot be expressed as the ratio of two integers. rational numbers have infinite non-repeating digits after the decimal point.
How do you prove a number is irrational?
How do you Prove that Root 3 is Irrational? Root 3 is irrational is proved by the method of contradiction. If root 3 is a rational number, then it should be represented as a ratio of two integers. We can prove that we cannot represent root is as p/q and therefore it is an irrational number.
