Madam Marie Curie: A Radiant Legacy of Science, Sacrifice, and Inspiration Maria Salomea Skłodowska-Curie (7th November 1867 – 4th July 1934) simply known as Marie Curie, was a Polish and Naturalised-French (1895-1934) physicist and chemist who conducted pioneering research on radioactivity. The early life and education of Marie Curie were marked by resilience, intelligence, and…

Sir Isaac Newton: The Extraordinary Life And Legacy Of A Scientific Genius.
—
by
Sir Isaac Newton (1643–1727) stands as one of the most influential figures in scientific history, whose discoveries transformed our understanding of the physical world. Known primarily for his laws of motion and universal gravitation, Newton’s work laid the groundwork for classical mechanics, significantly advanced mathematics, and changed the way humanity perceives the natural universe. This…

It was 5:00 p.m. on Thursday, January 7, 1610. Galileo Galilei stood in his garden in Padua, northern Italy. In his hands, he held a telescope which he recently built by himself. That night, he had decided to try something, no one else has done before: he was going to point his telescope toward Jupiter.…

What Do You Mean By A Classical Distribution Function? Applying The Classical Distribution Function Establish The Principle Of Equipartition of Energy.
—
by
Classical Distribution Function: The ratio of the number of particles distributed in the states to the number of states is called distribution function. It is the average number of the particles per quantum state of the system. The Classical or the Maxwell-Boltzmann distribution function is given by, where, is constant, is Boltzmann constant and is…
