Aristotle is known as the Father of Biology because of his extensive studies on the structure and behavior of animals. He was one of the first to use systematic observation and classification in the study of living things. While Mendel is the father of genetics, Aristotle's work laid the foundation for the biological sciences.

Euclid was a Greek mathematician often referred to as the father of geometry. His work Elements is one of the most influential works in the history of mathematics, serving as the main textbook for teaching geometry for centuries.

John Maynard Keynes was a British economist whose ideas, known as Keynesian economics, fundamentally changed the theory and practice of macroeconomics.

René Descartes is widely considered the father of modern mathematics for his development of Cartesian geometry, which bridged the gap between algebra and geometry.

Galileo Galilei used his telescope to observe the moon and was the first to document that its surface was not smooth, but covered in craters and mountains.

Adam Smith is often hailed as the father of modern economics.

Aristotle is known as the father of biology because he was the first to categorize living things based on their characteristics. He conducted extensive observations of animals and plants, laying the groundwork for the scientific study of life. His student Theophrastus is similarly known as the father of botany.

Galileo Galilei was the first to observe Saturn's rings through a telescope in 1610, though he initially described them as "appendages." It was later in 1655 that Christiaan Huygens correctly identified them as a ring system.

Astrometeorologist studies the theoretical effects of astronomical bodies and forces on Earth's atmosphere. So, it is incorrect. Correct answer is astronomer.

The phrase 'Number rules the universe' is famously attributed to the Greek philosopher and mathematician Pythagoras. He and his followers believed that mathematical relationships were the fundamental building blocks of reality.
