Great Engineers & Scientists

In 1676, Sir Isaac Newton wrote "If I have seen further it is by standing on ye shoulders of Giants." In this blog, we take Newton's words to heart, and recognize the many great engineers and scientists upon whose shoulders we stand.

So who do you think of when you hear "Great Engineer"? Let us know! Submit a few paragraphs about that person and we'll add him or her to the pantheon. Please provide a citation for the material that you submit so that we can verify it. Please note - it has to be original material. We cannot publish copywritten material or bulk text taken from books or other sites (including Wikipedia).

Leonhard Euler Remembered with a Google Doodle

Posted April 15, 2013 11:50 AM by LakeGrl

Today's Google Doodle honors a Swiss mathematician named Leonhard Euler. "Leonhard Euler was a pioneering Swiss mathematician and physicist. He made important discoveries in fields as diverse as infinitesimal calculus and graph theory." Wikipedia

He was considered one of the greatest mathematicians that ever lived and the most prolific, introducing much of modern mathematical terminology and notation. He was born April 15th 1707 in Basel, Switzerland and died 9/18/1783 in Russia. A large number of functions, equations and formulas are named in his honor. Lists of things named after Leonhard Euler from wikipedia.

Euler worked in many areas of mathematics including calculus, trigonometry, algebra, geometry, number theory, physics, and lunar theory. He is unique in that he has 2 numbers named after him, Euler's number in calculus, e, 2.71828, and Euler's Constant γ,(gamma) 0.57721.

According to Science World, he had a phenomenal memory and once did a calculation in his head to settle an argument between students. He lost the sight in his eyes possibly due to cataracts, but continued to publish by dictation. He published over 800 papers in his lifetime. He truly was a mathematical genius. Francois Argo said of him, "He Calculated just as men breathe, as eagles sustain themselves in the air" (Beckmann 1971, p. 143; Boyer 1968, p. 482).

His output was so abundant,

This deserves to be redundant:

And I searched to make sure it was not a duplication too! Oh well:)

This brings back some memories! I finished my engineering degree way back in 1987. e, ln, real and imaginary, Poisson, Lagrange, Bernouli, etc! All such a blur, but 25 years ago, they were my life!

Thanks for sharing.
