A surd is a number expressed as a square root (or some other root). Such roots are usually irrational; but Irrational Numbers also include other numbers, which CAN'T be expressed as the root of a rational number. For example, pi and e.

What is the difference between surds and irrationals?
Roots that are irrational are called surds. There are irrational numbers that are not surds since they are not roots of any equation. For example, Pi. Rational roots, such as square root of 4, are not surds.

How do you understand Surd's in maths?
How one understands surds depends on the person. If you would like to know what surds are, or have help understanding surds A surd is an unresolved radical, meaning that it is a root with the radical sign still on it. It is easier (and more accurate) to express it this way than writing it out for many numbers if the root is irrational. The concept of irrational numbers (which is what surds are, usually) can be confusing. In short, they are numbers that are not rational, that is, they cannot be written as a fraction. When using surds in math, you treat them just as you would a written out number.

Who is the father of surds?
The term "father of surds" is often attributed to the ancient Greek mathematician Hippasus of Metapontum. He is known for his work in irrational numbers, particularly for demonstrating the existence of numbers that cannot be expressed as the ratio of two integers, which are now considered surds. His discovery challenged the Pythagorean belief that all numbers could be expressed as whole numbers or ratios.
Can you give one example for surd which is not irrational?
It is impossible to have a surd that is not irrational. Surds are defined to be an irrational number (square root of a number).
