Joseph Fourier - Biography: Politician & Scientist
Jean-Baptiste Joseph Fourier, French mathematician and physicist, was born in Auxerre , years ago today. He is best known for the mathematical techniques that he developed in his analytical theory of heat transfer. Over the past two centuries, his methods have evolved into a major subject, harmonic analysis, with widespread applications in number theory, signal processing, quantum mechanics, weather prediction and a broad range of other fields. He established the fundamental equation that governs the diffusion or spreading out of heat, and solved it by using the infinite series of trigonometric functions that we now call Fourier series.
Jean-Baptiste Joseph Fourier et la découverte de l'effet de serre
The first opportunity came in , when Bonaparte was promoted to brigadier general for the decisive part he played in the siege of Toulon, which ousted the British from mainland France. After the coup de Thermidor in , Napoleon fell out of favor and was imprisoned. After his release he ended up preserving the new government from the Parisian Mob with artillery fire, an event that has become known as the 'Whiff of Grapeshot.
The life of Baron Jean Baptiste Joseph Fourier - the mathematical physicist has to be seen in the context of the French Revolution and its reverberations. One might say his career followed the peaks and troughs of the political wave. His life spanned the eruption and aftermath of the Revolution; Napoleon's rise to power, defeat and brief return the so-called Hundred Days ; and the Restoration of the Bourbon Kings. He was orphaned before he was ten years old and grew up with his aunt and uncle in the same town. Under teachers of the Benedictine order he showed himself to be a fast and diligent student.
