A Note on Fourier and the Greenhouse Effect

Web5 de abr. de 2024 · Jean-Baptiste-Joseph Fourier (March 21, 1768-May 16, 1830). French physicist and mathematician. Jean-Baptiste-Joseph Fourier began paving the way toward the understanding of the greenhouse effect. In 1824, his work led him to believe that the gases in the atmosphere could actually increase the surface temperature of the Earth. Fourier originally defined the Fourier series for real -valued functions of real arguments, and used the sine and cosine functions in the decomposition. Many other Fourier-related transforms have since been defined, extending his initial idea to many applications and birthing an area of mathematics called … Ver mais A Fourier series is an expansion of a periodic function into a sum of trigonometric functions.
