Leonhard Euler was born on April 15, 1707 in Basel, Switzerland and passed away on September 18, 1783. Today is exactly 306^{th} years after his birth. Leonhard Euler is considered by many of the world’s top mathematicians as the greatest mathematician who have ever lived.

Leonhard Euler is the only mathematician who have two Mathematics Numbers named after him. The Euler’s Number in Calculus (e) and the Euler-Mascheroni Constant γ (gamma). He also contributed to the modern day mathematics naming and mathematics notation systems which we still use today.

These naming and formulas that Leonhard Euler created now nearly exists for 300 years.

**Why all the fuzz about Leonhard Euler?**

Many people who are not that into mathematics may not realize how deeply mathematics are embedded into humanity, and the importance of mathematics on humanity. Mathematics are used every day in science and architecture to calculate formulas and ingredients to create products, medicine, buildings and cars.

When an engineer builds a bridge or a 20 story building, the engineer needs to calculate the strength of the materials used in the building to make sure that the building or bridge will be able to carry the weight.

Without the formulas and mathematics insight by mathematicians like Leonhard Euler the world may not have evolved the way it had and we might have still been in the middle ages.

**Leonhard Euler Mathematics**

Leonhard Euler was simply brilliant and instead of focusing on a niche area of mathematics he focused on a very broad area of mathematics, and is noted for his worked in geometry, infinitesimal calculus, trigonometry, algebra, and number theory, as well as continuum physics, lunar theory and other areas of physics.

**Leonhard Euler Honors**

Today April 15, 2013 Google have selected Leonhard Euler to be honored on the Search Engine homepage this honor is however not the first time that Leonhard Euler have been honored for his work in mathematics. Leonhard Euler have been honored on a stamp in Germany and the Soviet Union and have also appeared on the 10-Francs Switzerland money.

Today’s Google Doodle have been cleverly designed to represent the life and legacy of Leonhard Euler and his work and formulas are very visible in the doodle.
