## The Number 2 is the First Prime Number

There are only eight prime numbers under 20, and 2 is the only even prime number.

By definition, a prime number is only divisible by itself and 1.

## The Number 2 is Either the Third or Fourth Number in the Fibonacci Sequence

This depends on whether you begin the sequence with 0 or 1.

## A Number is Considered Even if it is Divisible by 2

While this may seem obvious, it can be a helpful reminder if you ever get confused between odd and even numbers.

## Something Described as Two-Dimensional Only Takes Up Space in Two Dimensions

For example, a rectangle drawn on a piece of paper only has two dimensions: length and width.

If a character in a film is described as two-dimensional, it means they lack depth or complexity.

## The Atomic Number of Helium is 2

Helium, the first of the Noble gases, is completely colorless, odorless, and non-toxic.

It is also the second lightest gas and is commonly used to inflate balloons that float in the air.

## A Binary Number is a Number That Uses the Base-2 Number System

This system uses only two numbers, typically 0 and 1.

Our standard system of counting is based on 10.

## A Binary Star System Contains Two Stars Orbiting Each Other

Binary star systems contain two stars at their center, each orbiting around the other.

## The Prefix “Bi-” Means Two and Can Be Found in Thousands of Words

Words such as bicycle, binoculars, and biped all contain the prefix “bi-.”

There are several examples of words that contain the prefix “bi,” which means two. For instance, “bilingual” means knowing or using two languages, “bisect” refers to cutting something in half, “biannual” means occurring twice a year, and “bicycle” is a vehicle with two wheels.

The asteroid 2 Pallas is the second-ever asteroid to be discovered. Its formal name includes the number “two,” indicating that it was the second classified planet. Although it was once classified as a planet, it was later reclassified as an asteroid in the 19th Century. Pallas has a varying orbit between Mars and Jupiter.

The number two is prevalent in mythology, particularly in Roman mythology. The founding of Rome is linked to the story of two brothers named Romulus and Remus, who were raised by wolves after being thrown into the Tiber River as infants. Romulus later killed Remus and became the first king of Rome.

In culture and history, the focus is often on the first or third, with little attention paid to the second. This is similar to how middle children can often feel left out. However, as the saying goes, “two’s company, three’s a crowd.”
