"Masterpieces from Newton to Lebesque"

This gallery was inspired by William Dunham's (2005) book with the same name as the gallery exhibit. There is a deliberately small display of mathematicians as to not overwhelm the visitor.

As you pass through the gallery, you will see a little bit of each mathematician's personal life as well as a contribution that he has made to the development of calculus.

Enjoy your tour.

Feel free to take pictures.

No smoking please.

Welcome to the Pioneer Wing!

The foundation of calculus began with the independent work of Newton and Leibniz. It was followed-up by the Bernoulli Brothers and Euler, who expanded the concepts of limits, derivatives, infinite sequences, and infinite series.

As you pass through this wing, it is important to keep in mind that the early pioneers were not as critical in proving their work mathematically as they instead spent their time formulating ideas for this new branch of mathematics.

Looking back, it is amazing how the early pioneers conceived ideas for limits, infinity, sequences, and series. Please keep in mind also that their methods also shifted from the use of geometric means to algebraic as their perspectives grew.

Founders Hall

There had been much debate who is the founder of calculus, but most historians scoot around this debate by noting that Sir Isaac Newton and Gottfried Leibniz were independently the originators of calculus.

The Modernists Hall

**ENTERING**

Welcome to the Classical Wing!

The early pioneer's perspectives of calculus shifted from geometry and curves to analysis and functions, particularly driven by Euler. However, lack of time most likely left some of his ideas less precise and even less accepted “as is” for the mathematics community of that time.

In the Classical Wing, you will come across mathematicians whose work focused on formalizing calculus in the way in which we know it today. Their style of proof and precision is akin to that found in Euclidean geometry. Another notable difference within the mathematicians in this wing is their goal to make generalizations for many functions, unlike the pioneers who focused specifically on particular functions.

Welcome to the Modern Wing!

As you leave the Classical Wing, you may be thinking that much of calculus as we know it has been formalized by this point. What's left?

With a formalized and solid foundations now established for calculus, modern mathematicians had a strong basis on which to test new theorems and to promote advances in technology and engineering.

In this final wing, we briefly shed light onto the contributions that modern mathematicians who might not typically make it in a gallery; they demonstrate how calculus advances development in other fields.

The Bernoulli Brothers Hall

The Bernoulli Family was a well known Swiss family that made significant contributions to mathematics and science in the 17th and 18th Centuries. The "Bernoulli Brothers" - Johann and Jakob - are the family members with the most notable contributions to calculus.

The Euler Room

Swiss mathematician Leonhard Euler (1707-1783) is often considered the greatest mathematician to have ever lived. It is one reason why he has his own room in the gallery - room for us to expand and add more of his to our collection.

Contributions to calculus:

Infinitesimal calculus

Structure for analysis

Power series

Calculus of variations

Euler-Lagrange equation

Much, much more!

Disclaimer

The ideas of calculus can be traced back to Archimedes of Syracuse (c. 287-212 BCE), to Pierre de Fermat (1601-1665), and to Carl Friedrich Gauss (1777-1855) and more. However, we apologize that the gallery is unable to mention every mathematician’s contribution to calculus. This would be an enormous undertaking and is restricted by the size of our gallery.

As our facility continues to expand, we hope that more mathematicians can be included to our gallery collection. For now, there are three main wings to our gallery, covering three centuries of the history of calculus for you to enjoy.

Thank you for visiting.

Works on logarithms within calculus

Was paid by Marquis de l'Hospital to write calculus problems (and l'Hospital's rule), and in essence wrote the first calculus textbook.

Johann Bernoulli was Leonhard Euler's teacher.

Jakob Bernoulli (1654-1705)

Jakob (James, Jacques) Bernoulli was the older of the famous Bernoulli brothers. Jakob was very pro-Leibniz in the Newton-Leibniz controversy on who first founded calculus.

Works on harmonic series

Bernoulli's differential equation

Jakob Bernoulli also made many contributions to the field of probability. He also discovered the constant

The Cauchy Room

French mathematician Augustin-Louis Cauchy (1789-1857) is best known for starting the process of formalizing calculus and using rigorous proofs for proving theorems. Like his predecessor Euler, he has his own room with space for the expansion of his works as they are collected for the gallery. His contributions are many with the more popular ones listed below.

Contributions to calculus:

Like Cauchy, the mathematicians in this hall supported the need to make calculus more rigorous and well-defined instead of being based more on intuition.

Although Liouville is a lesser known contributor to the development of calculus, he gives us an example of how the developments in calculus were overlapping into other branches of mathematics and science.

Calculus has undergone many changes from its inception to the present. It has gone from an idea about curves to functions, from geometry to algebra, and from intuitive ideas to rigorous proofs and definitions.

Calculus helps solve the simplest and most complex of problems. It provides a way for our conceptions about limits and infinity to be challenged on one hand and enhanced on another.

Calculus has changed society in many ways, and it is exciting to think what lies ahead for us in the 21st Century. Please return to visit the Postmodern Wing envisioned for this gallery.
