---My Introduction---
- Hi, I'm Daniel5127. Occasionally, I consider myself as Mathematician because I like to study the Mathematics such as Calculus. I first discovered the Wikipedia in June 2005. As a Wikipedian, I'm a 20 year old boy (teenager) as College student, and live in Los Angeles, California, America. I will help you with anything if you don't know how to use Wikipedia, you don't understand the way of using in Wikipedia, or have any problems with editing. I've been a Wikipedian since March 3, 2006. So, I'm glad to see you. Ahh, my hobby is to study Science, because I want to be scientist in the future. I'm quite proud of being chinese Wikipedian. I'm also interested in Astrology, something that tells about fortune of the day. The astrology book is called The New Astrology. This book is dedicated to everyone.
Leonhard Euler (1707–1783) was a Swiss mathematician and physicist. He developed important concepts and proved mathematical theorems in fields as diverse as calculus, number theory and topology. Euler introduced much of the modern mathematical terminology and notation, particularly for mathematical analysis, such as the notion of a mathematical function. He is also renowned for his work in mechanics, optics and astronomy. Euler is considered to be the preeminent mathematician of the 18th century and one of the greatest of all time. According to Guinness World Records, he is also the most prolific; his collected works fill 60 to 80 quarto volumes. Euler was featured on the sixth series of the Swiss ten-franc banknote and on numerous Swiss, German and Russian stamps. The asteroid 2002 Euler was named in his honor. This portrait of Euler was created by the Swiss painter Jakob Emanuel Handmann in 1753 and is now in the collection of the Kunstmuseum Basel.Painting credit: Jakob Emanuel Handmann; restored by Bammesk
Awarded to Daniel for never letting others make you angry or sad (even the grumpy vandals!), for alwaysassuming good faith in every situation (whether you know that or not!), for always asking questions when you don't understand and learning from others answers... and, for just being a kind-hearted great-natured wikipedian! Congrats! - Glen 16:09, 19 June 2006 (UTC)
