Ernest William Wallis (1860-1934) was a British mathematician who made significant contributions to the fields of geometry and trigonometry.
Wallis was born in Kent, England, and received his education at University College, Oxford. After graduating with a degree in mathematics, he went on to teach at various schools and universities, eventually becoming a professor at the University of Glasgow.
One of Wallis's most notable contributions to mathematics was his work on non-Euclidean geometry, which involves geometries that do not follow the traditional rules of Euclidean geometry. This type of geometry was first proposed by mathematician János Bolyai in the early 19th century, and Wallis was one of the first to fully explore its implications and applications. He published several papers on the subject, including "On a Generalization of the Geometry of Lobachevski" and "On a New Type of Non-Euclidean Geometry."
In addition to his work on non-Euclidean geometry, Wallis also made significant contributions to trigonometry. He published a number of papers on trigonometric identities and developed a new method for calculating trigonometric functions that was more efficient than previous methods.
Despite his many achievements in mathematics, Wallis is not as well known as some of his contemporaries, such as Albert Einstein or Henri Poincaré. However, his contributions to geometry and trigonometry have had a lasting impact on the field and continue to be studied and used by mathematicians today.
Overall, Ernest William Wallis was a brilliant mathematician who made significant contributions to the fields of geometry and trigonometry. His work has had a lasting impact on the field and continues to be studied and used by mathematicians today.

It was a feat which was rightly considered remarkable, and Oldenburg, the Secretary of the Philosophical Transactions of the Royal Society of 1685. Contributions in Mathematics During his tenure in Oxford, John Wallis became known as a leading mathematician of his time. This was the time of the Civil war between both these parties. He worked extensively in the field of geometry and laid the foundation for calculus Taylor 2. Wallis replied with the pamphlet Due Correction for Mr Hobbes, or School Discipline for not saying his Lessons Aright to which The Marks of the Absurd Geometry, Rural Language etc.
He finished his copy in just a few weeks and began developing his formulas right thereafter. The book is also known as the Arithmetic of Infinitesimals, or a New Method of Inquiring into the Quadrature of Curves and other More Difficult Mathematical Problems. Despite this, he was appointed Savilian Professor of Geometry at Oxford, where is took the degree of D. Wallis held the Savilian Chair for over 50 years until his death and, even if he was appointed for the wrong reasons, he most certainly deserved to hold the chair. Newcastle, Australia, 1970-1985; professor, Southern Illinois U. Under his helm, the Oxford University became a center for mathematical excellence. Minnesota Symposium on Child Psychology: Culture and Developmental Systems, Volume 38.
An interesting John Wallis fact is that in 1644, he was assigned as secretary to the Westminster Clergy. Although Wallis is known for his mathematical manuscripts, he has published works in other disciplines as well. Historians thought of this as a wrong choice as he was not a popular mathematician during his time of appointment. Expectedly, the book became an instant favorite, with readers enjoying the content for centuries after its publication.

Shewing the Original, Progress, and Advancement thereof, from time to time, and by what Steps it hath attained to the Heighth at which it now is. And each designs at least in the same Infinite Line one Single Point: And but one. Biography John Wallis's father was the Reverend John Wallis who had become a minister in Ashford in 1602. It was during the 1631 Christmas holidays that Wallis first came in contact with mathematics when his brother taught him the rules of arithmetic. . From school in Felsted he went to Emmanual College Cambridge, entering around Christmas 1632.
Quickly his love of mathematics, which he had as a student but which had never found the opportunity to flourish, now came pouring out. London 51 1 1997 , 13- 22. Born: Birthplace: Ashford, England, United Kingdom Star Sign: Died:. During the civil war, he decoded Royalist messages for the Parliamentarians, a favor that vastly improved his career. The feat made his fortune. He was a highly respected man known widely in the area. A lesser-known but equally important work of his was the Tract on Conic Sections, published in the year 1655, where Wallis described the curves which could be obtained as cross sections by cutting a cone with a plane as properties of algebraic coordinates.
To avoid the use of actual infinity, bce and bce developed a technique, later known as the The issue of infinitely small numbers led to the discovery of y over the change in x for a line touching a curve at a given point x, y , he found it useful to look at the ratio between d y and d x, where d y is an y produced by moving an infinitesimal amount d x from x. Certainly the previous holder of the chair, Peter Turner, was dismissed for his Royalist views.

Negative Math: How Mathematical Rules Can Be Positively Bent. This laid the foundation of his most famous work of Arithmetica Infinitorium which was published in 1656. One night he calculated the square root of a number with 53 digits in his head. Wallis, however, gained by signing the petition against the King's execution for, in 1660 when the monarchy was restored and Charles II came to the throne, Wallis had his appointment in the Savilian Chair confirmed by the King.
A given magnitude is here represented by the numerical ratio which it bears to the unit of the same kind of magnitude: thus, when Wallis wants to compare two lengths he regards each as containing so many units of length. Retrieved 5 May 2018. There was considerable controversy over his election to this post. For this purpose, he introduced the word interpolation in this work, which was used to deal with fractional indexes. No third option can be maintained, unless as perchance it may seem to some was are all mad. Born in 1616, John Wallis is deemed one of the most influential mathematicians that have ever walked the planet. Retrieved 9 June 2013.
It was during this time that the first of two events which shaped Wallis's future took place:-. There, to avoid being diverted to other discourses and for some other reasons, we barred all discussion of Divinity, of State Affairs, and of news other than what concerned our business of philosophy confining ourselves to philosophical inquiries, and related topics; as medicine, anatomy, geometry, astronomy, navigation, statics, mechanics, and natural experiments. Here, Wallis discovered his skills with cryptography and used them to decode the letters of the Royalists for Parliamentarians. Many scientists like Huygens, Hobbes, Fermat, etc. He took the standard bachelor of arts degree and, since nobody at Cambridge at this time could direct his mathematical studies, he took a range of topics such as ethics, metaphysics, geography, astronomy, medicine and anatomy.
