Work is the product of force and displacement.

Einstein’s insights laid the foundation for numerous scientific advancements, including the development of modern quantum mechanics, cosmology, and technologies like GPS and nuclear energy. His work remains central to both theoretical and applied physics.

The theory of the expanding universe was first proposed by Belgian physicist and priest Georges Lemaître in 1927. Lemaître suggested that the universe is not static but expanding, based on his interpretation of Einstein’s general theory of relativity and observations ...

The discovery of radioactivity is credited to French physicist Henri Becquerel in 1896. While studying phosphorescent materials, Becquerel investigated whether certain substances emitted radiation similar to X-rays, which had been recently discovered by Wilhelm Roentgen. He experimented with uranium salts ...

Madame Marie Curie made several groundbreaking contributions to science, particularly in the fields of physics and chemistry. She is best known for her pioneering research on radioactivity, a term she coined. Along with her husband Pierre Curie, she discovered two ...
