Joseph Fourier was a French mathematician, born on 21 March 1768 in Auxerre, France. His name is closely associated with the Fourier series and Fourier transform, mathematical tools utilised in a wide range of applications. He is also one of the 72 scientists and mathematicians whose names are engraved on the Eiffel Tower.

Fourier is celebrated for his extraordinary analytical skills and his pioneering theory of heat, which opened up an entirely new branch of physics and mathematics.

According to Cédric Villani, a mathematician and Fields Medal laureate, Fourier's work placed him at the forefront of scientific innovation.

“For the generations after him, Fourier remained the emblematic hero of mathematical physics. Some people even say he's the creator of mathematical physics,” Villani said.

Fourier was among the first mathematicians to express heat phenomena using mathematical equations. His groundbreaking work, presented in his 1822 publication The Analytical Theory of Heat, demonstrated how heat flows through materials, using what are now known as Fourier series and Fourier transforms.

These tools have since become indispensable in physics, engineering, and applied mathematics.

Fourier famously stated in Latin, "Fire obeys the laws of numbers," encapsulating his belief in the universality of mathematical principles.

His methods and equations extended far beyond the study of heat, finding applications in diverse areas such as signal processing, climate science, and quantum mechanics.

Villani noted that Lord Kelvin, another prominent mathematician and physicist, described Fourier’s contributions as "a great mathematical poem," emphasising their elegance and profound impact. Fourier’s theory of heat conduction not only revolutionised physics but also laid the foundation for mathematical physics as a discipline.

Fourier’s influence was not confined to academia. In 1802, he was appointed prefect of the Isère regional district under Napoleon's administration. During his tenure, he contributed significantly to the region's infrastructure, including supporting the construction of roads and canals.

Despite his remarkable achievements, Fourier’s life was tragically cut short. He died in 1830 at the age of 62, leaving behind a legacy that continues to shape modern science and mathematics.

For those who don't know this book of Topology is rated very positively and Free ! Some professors teaching this branch of Mathematic may be able to confirm this.

Topology is an important and interesting area of mathematics, the study of which will not only introduce you to new concepts and theorems but also put into context old ones like continuous functions. However, to say just this is to understate the significance of topology. It is so fundamental that its influence is evident in almost every other branch of mathematics. This makes the study of topology relevant to all who aspire to be mathematicians whether their first love is (or will be) algebra, analysis, category theory, chaos, continuum mechanics, dynamics, geometry, industrial mathematics, mathematical biology, mathematical economics, mathematical finance, mathematical modelling, mathematical physics, mathematics of communication, number theory, numerical mathematics, operations research or statistics. Topological notions like compactness, connectedness and denseness are as basic to mathematicians of today as sets and functions were to those of last century.

For the reader who has not previously studied an axiomatic branch of mathematics such as abstract algebra, learning to write proofs will be a hurdle. To assist you to learn how to write proofs, in the early chapters I often include an aside which does not form part of the proof but outlines the thought process which led to the proof.

Since 1985 with the last update dating from this year... Amazing commitment !

This site contains the mathematical archives of Alexander Grothendieck from 1949 to 1991. There you will find manuscripts, "typescripts", sometimes printed documents, in a classification essentially faithful (when it existed) to the author's classification . Of the 28,000 (approximately) pages in this collection, only 18,000 (approximately) are currently accessible

I hope some of us will benefit from his knowledge.

The art of scientific prediction has seeped into every aspect of our lives, influencing our habits and perspectives. Weather, transport, space conquest, architecture and even agriculture: our daily lives are inextricably linked to forecasts. In this first season, Cédric Villani takes us into the thrilling story of the invention of differential equations, calling on Isaac Newton, Christian Huygens, Leonhard Euler, Henri Poincaré...
