Pi is not a rational number.

• A rational number can be expressed as a ratio of two integers, but pi cannot be expressed in this way.

• Pi is an irrational number with an infinite non-repeating decimal expansion.

• Proof of pi's irrationality was first given by Johann Lambert in 1761.

Fundamental concepts in physics and thermodynamics

• Force is a push or pull on an object that causes it to accelerate

• Momentum is the product of an object's mass and velocity

• Laws of motion describe how objects move and interact with each other

• Thermodynamics is the study of heat and its relationship with energy and work

• First law of thermodynamics states that energy cannot be created or destroyed, only transferred or converted

A rational number is a number that can be expressed as a ratio of two integers.

• Rational numbers include fractions and terminating or repeating decimals.

• They can be positive, negative, or zero.

• Examples include 1/2, -3/4, and 0.25.

• Irrational numbers, such as pi and the square root of 2, are not rational.

Pythagoras theorem states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

• The theorem is named after the ancient Greek mathematician Pythagoras.

• It is often written as a^2 + b^2 = c^2, where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

• It is used in various fields such as engineering, architecture, and physics to calculate distances, angles, and forces.

• For example, i...read more
